Relação entre o índice de resistência vascular e o sucesso hemodinâmico de revascularizações distais dos membros inferiores / Vascular resistance index and the immediate hemodynamic success of lower limb distal artery revascularization

Resumo Contexto A cirurgia de revascularização é proposta para restaurar o fluxo sanguíneo para o pé nos casos de isquemia crítica (IC) devido a doença arterial obstrutiva periférica dos membros inferiores (MMII). O uso de ultrassonografia com Doppler (USD) vem despontando nos últimos anos como um método de grande valor para o planejamento cirúrgico dessa intervenção. Objetivos Avaliar a relação entre o índice de resistência (IR), mensurado por meio de USD, e o sucesso hemodinâmico imediato da cirurgia de revascularização dos MMII em pacientes com IC. Métodos O tipo de estudo empregado foi a coorte prospectiva, na qual foram avaliados 46 pacientes portadores de IC dos MMII submetidos à operação de revascularização infrainguinal por angioplastia ou em ponte de agosto de 2019 a fevereiro de 2022. Todos os pacientes foram submetidos à avaliação clínica vascular, à USD com medida do IR das artérias distais dos MMII, à arteriografia dos MMII e à aferição do índice tornozelo-braquial (ITB) no período pré-operatório. No pós-operatório imediato, todos os pacientes foram submetidos à nova aferição do ITB. Resultados Entre os 46 pacientes avaliados, 25 (54,3%) eram do sexo masculino. A idade variou de 32 a 89 anos (média de 67,83). Quanto ao sucesso hemodinâmico, avaliado pela comparação do ITB pré e pós-operatório, constatou-se que 31 (67,4%) pacientes apresentaram sucesso hemodinâmico após cirurgia de revascularização (aumento do ITB em 0,15 ou mais). Foi observada correlação positiva (p ≤ 0,05) entre o IR da artéria distal revascularizada do MMII e o sucesso hemodinâmico imediato avaliado pela aferição do ITB (IR menor e sucesso hemodinâmico). Conclusões Na presente pesquisa foi observada uma correlação positiva entre o índice de resistência arterial distal e o sucesso hemodinâmico nas revascularizações dos membros inferiores, avaliada através do índice tornozelobraquial, de forma que, quanto menor foi o IR, maior o sucesso hemodinâmico obtido.

Abstract Background Revascularization surgery is used to attempt to restore blood flow to the foot in patients with critical ischemia (CI) caused by peripheral arterial occlusive disease of the lower limbs (LL). Ultrasonography with Doppler (USD) SAH emerged in recent years as a highly valuable method for planning this surgical intervention. Objectives To evaluate the relationship between the resistance index (RI), measured with USD, and immediate hemodynamic success of LL revascularization surgery in patients with CI. Methods The study design was a prospective cohort assessing 46 patients with LL CLI who underwent operations to perform infrainguinal revascularization by angioplasty or bypass from August 2019 to February 2022. All patients underwent preoperative clinical vascular assessment with USD including measurement of the RI of distal LL arteries, LL arteriography, and measurement of the ankle-brachial index (ABI). All patients had their ABI measured again in the immediate postoperative period. Results Forty-six patients were assessed, 25 (54.3%) of whom were male. Age varied from 32 to 89 years (mean: 67.83). Hemodynamic success was assessed by comparison of preoperative and postoperative ABI, showing that hemodynamic success was achieved in 31 (67.4%) patients after revascularization surgery (ABI increased by 0.15 or more). A positive correlation (p ≤ 0.05) was observed between the RI of the distal revascularized LL artery and immediate hemodynamic success assessed by ABI (lower RI and hemodynamic success). Conclusions This study observed a positive correlation between the resistance index of the distal artery and immediate hemodynamic success of lower limb revascularizations, as assessed by the ankle-brachial index, so that the lower the RI the greater the hemodynamic success achieved.

Precisión y fiabilidad de la medición del índice tobillo-brazo utilizando un dispositivo oscilométrico versus el método Doppler / Accuracy and reliability of ankle-brachial index measurement using an oscillometric device versus the Doppler method

Introducción: la medición del índice tobillo-brazo (ITB) es una prueba de primera línea y con alta precisión diagnóstica para detectar la enfermedad vascular periférica (EVP). El método Doppler, considerado el estándar de oro, requiere del dispositivo y de un operador capacitado, lo que limita su uso en la atención primaria. Como alternativa, un método oscilométrico que emplea un dispositivo de presión arterial automático es una prueba simple y accesible que podría minimizar los sesgos del observador y eliminar la necesidad de capacitación especial. Objetivos: validar la capacidad diagnóstica de un dispositivo oscilométrico automatizado frente al método Doppler para la medición del ITB. Materiales y métodos: se incluyeron pacientes con diabetes mellitus tipo 1 y 2 (DM1 y DM2), mayores de 50 años, con uno o más factores de riesgo cardiovascular. Luego de que los pacientes permanecieran 5 minutos acostados, se registró la presión arterial sistólica (PAS) con tensiómetro Welch Allyn DS 45-11 y Doppler Vascular Contec Sonoline B 8 Mhz en ambas arterias tibiales posteriores y en arteria braquial derecha. Posteriormente se realizaron los mismos registros con monitor de presión arterial automático modelo Omrom HEM-7130. Se calculó el ITB de cada miembro inferior y las capacidades diagnósticas (sensibilidad [S-, especificidad [E], concordancia por coeficiente kappa, valor predictivo positivo [VPP] y valor predictivo negativo [VPN]) del método oscilométrico para detectar un ITB patológico por Doppler (≤0,90). Resultados: se evaluaron 66 pacientes, 52 varones y 14 mujeres, 7 con DM1 y 59 con DM2, 69 años de edad (DS 9,8), con una antigüedad de la DM de 18,05 años (DS 12,01). La prevalencia de EVP detectada por Doppler (ITB ≤0,90) fue del 16,7% (IC 95% 9,9-23,4). El método oscilométrico para detectar un ITB ≤0,90 por Doppler mostró una S del 72,7% (IC 95% 51,8-93,6), una E del 96,3% (IC 95% 92,4-100), una concordancia del 92,4% (IC 95% 87,5-97,3), un VPP del 80,0% (IC 95% 59,9-100) y un VPN del 94,6% (IC 95% 90,0-99,3). Conclusiones: el alto VPN hallado (condición esencial para un método de screening) significa que si el método oscilométrico da un ITB >0,90, hay un 94,6% de posibilidad de que el ITB por Doppler no sea ≤0,90. El VPP de 80% encontrado significa que si el ITB oscilométrico es ≤0,90, hay un 80% de posibilidad de que el ITB Doppler sea verdaderamente ≤0,90. Por lo tanto, consideramos que la simple medición del ITB con el método oscilométrico podría recomendarse en la atención primaria, donde se requieren métodos rápidos, fáciles y confiables.

Introduction: the measurement of the ankle-brachial index (ABI) is a first-line test with high diagnostic accuracy for the detection of peripheral vascular disease. The Doppler method, considered the gold standard, requires the device and a trained operator, which limits its use in primary care. Alternatively, an oscillometric method using an automated blood pressure device is a simple and affordable test that could minimize observer bias and eliminate the need for special training. Objectives: to validate the diagnostic capacity of an automated oscillometric device against the Doppler method for ABI measurement. Materials and methods: diabetes mellitus type 1 and 2 (DM1 and DM2) patients older than 50 years with 1 or more cardiovascular risk factors were included. After 5 minutes lying down, SBP was recorded with a Welch Allyn DS 45-11 sphygmomanometer and Contec Sonoline B 8 Mhz Vascular Doppler in both posterior tibial arteries and in the right brachial artery. Subsequently, the same recordings were made with an Automatic Blood Pressure Monitor Model Omrom HEM-7130. The ABI of each lower limb and the diagnostic capabilities (sensitivity [S], specificity [E], concordance by kappa coefficient, positive predictive value [PPV] and negative predictive value [NPV] of the oscillometric method to detect a pathological ABI were calculated by Doppler (≤0.90). Results: 66 patients were evaluated, 52 men and 14 women, 7 DM1 and 59 DM2, 69 years old (SD 9.8) with a history of diabetes of 18.05 years (SD 12.01). The prevalence of PVD detected by Doppler (ABI ≤0.90) was 16.7% (95% CI 9.9-23.4). The oscillometric method to detect an ABI ≤0.90 by Doppler showed an S of 72.7% (95% CI 51.8-93.6), an E of 96.3% (95% CI 92.4-100), a concordance of 92.4% (95% CI 87.597.3), a PPV of 80.0% (95% CI 59.9-100) and a NPV of 94.6% (95% CI 90 .0-99.3). Conclusions: the high NPV found (essential condition for a screening method) means that if the oscillometric method gives an ABI >0.90, there is a 94.6% chance that the Doppler ABI is not ≤0.90. The PPV of 80% found means that if the oscillometric ABI is ≤0.90, there is an 80% chance that the Doppler ABI is truly ≤0.90. Therefore, we consider that the simple measurement of ABI with the oscillometric method could be recommended in primary care, where fast, easy and reliable methods are adequate.

Association between appendicular skeletal muscle mass and ankle-brachial index in patients with type 2 diabetes / 中华健康管理学杂志

Objective:To assess the relationship between appendicular skeletal muscle mass (ASM) and ankle brachial index (ABI) among patients with type 2 diabetes.Methods:In this cross-sectional study, from July 2018 to March 2019, a total of 278 patients with type 2 diabetes treated in Zhongda Hospital were enrolled in this study, and there were 158 males and 120 females. General information and clinical biochemical parameters and ABI in the patients were collected. The appendicular muscle mass was quantitatively measured with body composition analyzer to achieve ASM. And the appendicular skeletal muscle mass index (ASMI), skeletal muscle index (SMI), and appendicular skeletal muscle mass/body mass index (ASM/BMI) were calculated respectively. Correlation analysis and multiple linear regression analyses with different adjustment models were conducted to analyze the correlation between ABI and above-mentioned indexes.Results:The Pearson correlation analysis showed that ABI had significant positive correlation with ASM, ASMI and ASM/BMI ( r=0.14, 0.13, 0.13, all P<0.05), but a marginal relation with SMI ( r=0.116, P=0.053). Multiple linear regression analysis suggested that ASMI ( β=0.053, 95% CI: 0.006-0.101, P=0.027) and AMI/ABI ( β=0.347, 95% CI: 0.040-0.654, P=0.027) were significantly related to ABI. Conclusion:ASM is positively associated with ABI in patients with type 2 diabetes.

Risk factors for recurrence of lower-extremity arteriosclerosis obliterans in patients after interventional surgery / 中国基层医药

Objective:To investigate the risk factors for the recurrence of lower-extremity arteriosclerosis obliterans in patients after interventional surgery.Methods:The clinical data of 98 patients with lower-extremity arteriosclerosis obliterans who received treatment in Lishui Municipal Central Hospital from January 2021 to January 2022 were retrospectively analyzed. They were randomly divided into a recurrent group ( n = 36) and a non-recurrent group ( n = 62). The immediate efficacy of interventional therapy and the follow-up were determined in each group. Clinical data, triglyceride, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol levels, neutrophil/lymphocyte ratio, and fasting blood glucose level were compared between the two groups. The risk factors for the recurrence of lower-extremity arteriosclerosis obliterans after interventional surgery were further analyzed using logistic regression analysis. Results:The success rate of interventional surgery for aortoiliac artery, superficial femoral artery, and inferior genicular artery were 95.35% (41/43), 97.73% (43/44), and 95.83% (46/48), respectively. Twelve-month follow-up results showed that the patency rate of lower-extremity vessels decreased with time ( P < 0.05). There was a significant difference in Trans-Atlantic Inter Society Consensus (TASC) classification between the two groups (11/26/18/7 vs. 4/5/10/17, χ2 = 18.33, P < 0.05). Ankle-brachial index (ABI) in the recurrence group was significantly lower than that in the non-recurrence group [(0.77 ± 0.12) vs. (0.40 ± 0.02), t = 18.31, P < 0.05]. There were no significant differences in triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and fasting blood glucose levels between the two groups (all P < 0.05). The neutrophil/lymphocyte ratio (NLR) in the non-recurrent group was significantly lower than that in the recurrent group [(1.98 ± 0.28) vs. (13.18 ± 0.50), t = 15.25, P < 0.05]. Logistic regression analysis results showed that ABI ( OR = 1.459, 95% CI: 1.163-1.832), TASC classification ( OR = 1.344, 95% CI: 1.090-1.658), surgical method ( OR = 1.392, 95% CI: 1.140-1.700) and NLR ( OR = 1.474, 95% CI: 1.184-1.836) were the influential factors of recurrence of lower-extremity arteriosclerosis obliterans (all P < 0.05). Conclusion:ABI, TASC classification, surgical methods, and NLR are the influential factors of lower-extremity arteriosclerosis obliterans after interventional surgery. The above indexes should be closely monitored in clinical practice to maintain the effects of interventional surgery.

Influence of spleen-qi deficiency syndrome in type 2 diabetes mellitus on Ankle-Brachial Index / 国际中医中药杂志

Objective:To investigate the influence of T2DM Spleen-qi Deficiency syndrome on Ankle-Brachial Index (ABI).Methods:The clinical data of 298 patients with T2DM who were hospitalized in Dongzhimen Hospital, Beijing University of Chinese Medicine from January 2019 to December 2021 were retrospectively analyzed. According to the diagnostic criteria of spleen-qi deficiency syndrome, the patients were divided into two groups: spleen-qi deficiency syndrome group and non-spleen-qi deficiency syndrome group. There were 142 patients in the spleen-qi deficiency syndrome group and 156 patients in the non-spleen-qi deficiency syndrome group. The differences of ABI between the two groups were compared, and the correlation between spleen-qi deficiency syndrome and clinical indicators (gender, age, body mass index, course of diabetes, history of hypertension, smoking history, fasting glucose, total cholesterol, triglyceride, platelet, hemoglobin, serum albumin, blood urea nitrogen, serum creatinine, estimated glomerular filtration rate) and ABI in T2DM patients was analyzed.Results:The left ABI [1.09 (1.00, 1.19) vs. 1.13 (1.03, 1.22)] and the right ABI [1.09 (0.96, 1.17) vs. 1.12 (1.02, 1.20)] in T2DM spleen-qi deficiency syndrome group were significantly lower than those in non-spleen-qi deficiency group ( P<0.05).The left ABI was significantly correlated with spleen-qi deficiency syndrome ( r=0.122, P=0.035) and estimated glomerular filtration rate ( r=0.137, P=0.018), and the right ABI was significantly correlated with spleen-qi deficiency syndrome ( r=0.123, P=0.034) and PLT ( r=-0.115, P=0.047). After correcting for other confounding factors by multiple linear regression analysis, there was significantly correlation between spleen-qi deficiency syndrome and ABI. Conclusion:Compared with the non-spleen-qi deficiency syndrome group, T2DM patients in the spleen-qi deficiency group had a lower ankle-brachial index and were more likely to develop peripheral arterial disease.

Control metabólico y su relación con enfermedad arterial periférica en sujetos con diabetes mellitus tipo 2: Estudio caso-control pareado

Objetivo : Evaluar la relación entre control metabólico y enfermedad arterial periférica (EAP) en pacientes con diabetes mellitus tipo 2 (DM2) del hospital María Auxiliadora (HMA). Material y métodos : Estudio caso-control pareado para sexo, de un análisis secundario basado en datos del servicio de endocrinología del HMA, Lima-Perú. Los casos con EAP, fueron aquellos con índice tobillo-brazo (ITB) < 0,9. Los controles fueron aquellos con ITB entre 0,9 y 1,3 en una relación 4:1 con respecto a los casos. Se definió como mal control metabólico si presentaron al menos uno de las siguientes: hemoglobina glicosilada ≥ 7 %, presión arterial sistólica ≥ 140 mm Hg, presión arterial diastólica ≥ 90 mm Hg, colesterol HDL< 40 mg/dl (varón) o < 50 mg/dl (mujer), colesterol LDL ≥ 100 mg/dl y triglicéridos ≥ 150 mg/dl. Se calculó el Odds ratio (OR) de mal control metabólico, tanto crudo como ajustado, según presencia de EAP mediante regresión logística. Resultados : Incluimos a 39 casos y 157 controles. Un 94,9 % y 82,2 % de los casos y controles presentaron mal control metabólico respectivamente (p<0,05). Al ajustar a edad, tiempo de diabetes, índice de masa corporal y antecedente de tabaco, los pacientes con mal control metabólico presentaron un OR de 5,45; (IC 95 % 1,17 - 25,2); p=0,030 de presentar enfermedad arterial periférica definido por ITB<0,9. Conclusión : El mal control metabólico presenta una relación independiente con EAP en pacientes con DM2 del Hospital María Auxiliadora. Metas terapéuticas centradas solo en la glicemia, elevarían la carga de enfermedad de complicaciones macrovasculares.

Objective : To assess the relationship between metabolic control and peripheral arterial disease (PAD) in patients with type 2 diabetes mellitus (DM2) in Maria Auxiliadora Hospital (MAH). Material and methods : This is a sex-matched case control study with a secondary analysis based on data from the endocrinology service of MAH, Lima, Peru. Cases with PAD were defined as those with 50 mg/dL (females), LDL cholesterol ≥100 mg/dL and triglycerides ≥150 mg/dL. Odds ratio values for poor metabolic control were calculated, both crude and adjusted, according to the presence or PAD, by using logistic regression. Results : We included 39 cases and 157 controls. A great majority of cases (94.9%) and of controls (82.2%) had poor metabolic control, respectively (p<0.05). When adjusting for age, time with diabetes, body mass index, and history of tobacco use, patients with poor metabolic control had OR at 5.45 (95% CI: 1.17 - 25.2) and p= 0.030 for having peripheral arterial disease, as defined by ATAI <0.9. Conclusion : Poor metabolic control showed and independent relationship with PAD in DM2 patients in Maria Auxiliadora Hospital. If therapy was only centered in glycemic control, it would increase the burden of disease of macrovascular complications.

Doença arterial obstrutiva periférica em pacientes com insuficiência renal crônica dialítica na região de Toledo - Paraná: prevalência e fatores de risco / Peripheral arterial disease in patients with dialytic chronic renal failure in the region of Toledo - Paraná: prevalence and risk factors

Introdução: a doença arterial obstrutiva periférica (DAOP) tem alta prevalência na população em geral e está associada a elevado risco de eventos cardiovasculares. O índice tornozelo-braquial (ITB), é um exame simples e não invasivo, com alta sensibilidade e especificidade no diagnóstico de DAOP. A patologia pode estar associada a diversos fatores de risco, entre eles a doença renal crônica terminal. Contudo, os dados que avaliam sua prevalência e fatores de risco na população de doentes renais crônicos são escassos. Objetivos: Determinar a prevalência e os fatores de risco da doença arterial obstrutiva periférica em pacientes com insuficiência renal crônica dialítica. Metodologia: trata-se de um estudo transversal, que analisou 117 pacientes com doença renal dialítica. Foram avaliados através de um questionário para identificação dos fatores de risco e submetidos ao teste do ITB, sendo considerado diagnóstico de DAOP quando ITB <0,9. Resultados: o presente estudo evidenciou uma prevalência de DAOP em 11% dos pacientes, sendo 10 classificados como DAOP leve e 3 como moderada. Não foram encontrados pacientes com DAOP severa. Entretanto, 54 pacientes (46,2%) apresentaram rigidez de parede vascular. Assim, foi possível verificar que 67 (57,3%) pacientes apresentaram o ITB alterado. Conclusão: a alta prevalência de DAOP em pacientes com doença renal crônica dialíticafoi análoga ao encontrado por outros autores. É importante ressaltar que pacientes com ITB > 1,3 podem gerar resultados falsos-negativos no diagnóstico de DAOP. Devido a isso, a prevalência pode estar subestimada, o que sugere que o ITB nesses pacientes deve ser avaliado com mais atenção.

Background: peripheral arterial disease (PAD) has a high prevalence in the general population and is associated with a high risk of cardiovascular events. The ankle-brachial index (ABI) is a simple noninvasive exam with high sensitivity and specificity in the diagnosis of PAD. Pathology may be associated with several risk factors, including terminal chronic kidney disease. However, data assessing their prevalence and risk factors in the chronic kidney disease population are scarce. Objectives: to determine the prevalence and risk factors of peripheral arterial disease in patients with dialytic chronic renal failure. Methods: this is a cross-sectional study that analyzed 117 patients with dialytic kidney disease. They were evaluated through a questionnaire to identify risk factors and were submitted to the ABI test, being considered a diagnosis of PAD when ABI <0.9. Results: the present study showed a prevalence of PAD in 11% of the patients, 10 classified as mild and 3 as moderate. No patients with severe PAD were found. However, 54 patients (46.2%) had vascular wall stiffness. Thus, it was possible to verify that 67 (57.3%) patients presented altered ABI. Conclusion: the high prevalence of PAD in patients with dialytic chronic kidney disease was similar to that found by other authors. It is important to highlight that patients with ABI> 1.3 may generate false negative results in the diagnosis of PAD. Because of this, the prevalence may be underestimated, suggesting that ABI in these patients should be evaluated more carefully.

A Study of Peripheral Arterial Disease in Type 2 Diabetes Mellitus with Relation to Ankle Brachial Pressure Index

Background : India shares a considerable share of the Global Disease Burden of Diabetes Mellitus which is a major public health concern. Among the many Vascular Complications of Diabetes, Peripheral Arterial Disease (PAD) is one and a major cause of Foot Related Disorders in Diabetics. The Ankle-Brachial Pressure Index (ABPI) is an efficient tool for objectively documenting the presence of lower extremity Peripheral Arterial Disease (PAD).The present study was conducted to find the prevalence of PAD in Diabetic Patients in a teaching hospital using ABPI.Materials and Methods : A total number of 100 cases of Type 2 Diabetic patients who were more than 40 years of age were included in the study after fulfilment of the inclusion and exclusion criteria. Ankle Brachial Pressure Index was measured in all and used to assess PAD. ABPI value of <0.9 was taken as indicative of PAD. Results : The prevalence of PAD using a ABPI Value of <0.9 was 31%. A significant association of PAD was found with duration of disease, hypertension, smoking and glycemic control.Conclusion : Peripheral Arterial Disease (PAD) is more commonly associated with Diabetes Mellitus than is generally thought. ABPI (Ankle Brachial Pressure Index) is a simple, noninvasive and cost-effective method for early detection of PAD.

Predictive value of ABI, HEART and TIMI scores for restenosis after stent implantation in patients with lower extremity arteriosclerosis obliterans / 国际外科学杂志

Objective:To explore the predictive value of ankle brachial index (ABI), HEART and thrombolysis in myocardial infarction (TIMI)scores for restenosis in patients with lower extremity arteriosclerosis obliterans (LEASO) after stent implantation.Methods:A retrospective study of 100 patients who were admitted to the Heyuan City People′s Hospital for stent implantation for LEASO from January 2015 to January 2020 and met the inclusion criteria were collected, and the patients were divided into restenosis group ( n=28) and patency group ( n=72) according to whether they were restenosis after operation. The clinical data of the two groups of patients were compared, including gender, age, disease course, history of cardiovascular and cerebrovascular diseases, smoking history, regular medication after surgery, number of stents, total length, bilateral lesions, total occlusion of lower extremities, length of vascular lesions, high-sensitivity C-reactive protein (hs-CRP), fasting blood glucose, triglyceride, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total cholesterol, fibrinogen, hemoglobin, platelet count and red blood cell count, and ABI, HEART, TIMI scores were compared, the relationship between ABI, HEART and TIMI scores and postoperative restenosis was further analyzed. Measurement data were expressed as mean±standard deviation ( ± s), and two independent samples t-test was used for comparison between groups; enumeration data were compared between groups by Chi-square test. Based on independent risk factors in multivariate Logistic regression analysis, a nomogram prediction model was constructed using R 3.3.2 software and software package rms. Correlations were analyzed using bivariate Pearson linear correlation analysis. The receiver operating characteristic curve (ROC) was used to evaluate the predictive value of each score and nomogram model for postoperative restenosis, and the results were expressed as the area under the curve (AUC) and the 95% confidence interval (95% CI) of the area. Results:Patients in the restenosis group and the patency group had a history of smoking, the proportion of irregular postoperative medications, the number of implanted stents, the total length of implanted stents, hs-CRP, fibrinogen, total cholesterol, red blood cell count levels, and ABI, HEART, TIMI scores were significantly different ( P<0.05). Pearson correlation analysis showed that ABI score ( r=-0.527, P=0.001) was negatively correlated with postoperative restenosis, and the HEART score ( r=0.604, P=0.010) and TIMI score ( r=0.719, P=0.005) were positively correlated with postoperative restenosis. A history of smoking, irregular medication after surgery, number of implanted stents>2, total length of implanted stent>212 mm, hs-CRP>2 mg/L, fibrinogen>3.7 g/L, ABI score ≤0.58, HEART score>6.30, and TIMI score>4.30 were independent risk factors for postoperative restenosis. The ABI, HEART, and TIMI scores predict the AUC of the ROC curve for postoperative restenosis of 0.813, 0.789, and 0.798, cutoff points were 0.58, 6.30 and 4.30 score, sensitivities were 95.64%, 91.17% and 92.51%, specificities were 64.18%, 55.43% and 58.62%, respectively. The consistency index (C-index) and ROC curve AUC of the nomogram prediction model were 0.811 (95% CI: 0.721-0.901) and 0.818 (95% CI: 0.732-0.904), respectively, indicating a good degree of discrimination. Conclusions:ABI, HEART and TIMI scores are independent risk factors for restenosis after stent implantation in LEASO patients. ABI, HEART and TIMI scores can effectively predict the risk of restenosis after stent implantation in patients.

Objective:To investigate the correlation between serum thyroglobulin antibody (TG-Ab) and thyroid peroxidase antibody (TPO-Ab) cconcentrations and arteriosclerosis development in middle-aged and older adult patients with depression.Methods:A total of 200 middle-aged and older adult patients with depression who received treatment in the Third People's Hospital of Huzhou from January 2018 to October 2019 were included in this study. They were divided into four groups ( n = 50/group) according to TG-Ab and TPO-Ab test results: TG-Ab-positive (group 1), TPO-Ab-positive (group 2), TG-Ab-positive and TPO-Ab-positive (group 3), TG-Ab-negative and TPO-Ab-negative (control group). Serum thyroid hormone level, ankle-brachial pressure index (ABI), brachial-ankle pulse wave velocity, and the incidences of intima-media thickening and plaque formation in the lower extremity arteries were compared between groups. Results:Total thyroxine concentration in the control group, groups 1, 2 and 3 was (89.96 ± 2.45) nmol/L, (101.29 ± 3.35) nmol/L, (90.09 ± 2.70) nmol/L, (97.55 ± 2.57) nmol/L, respectively. There was a significant difference in total thyroxine concentration between groups ( F = 3.85, P < 0.05). Brachial-ankle pulse wave velocity in the control group, groups 1, 2, and 3 was (1 327.55 ± 67.78) cm/s, (1 510.36 ± 83.05) cm/s, (1 422.71 ± 71.40) cm/s, (1 533.95 ± 87.01) cm/s, respectively. There was a significant difference in brachial-ankle pulse wave velocity between groups ( F = 65.12, P < 0.05). The incidence of intima-media thickening in the control group, groups 1, 2, and 3 was 18% (9/50), 50% (25/50), 32% (16/50), 60% (30/50), respectively. The incidence of plaque formation in the control group, groups 1, 2, and 3 was 22% (11/50), 56% (28/50), 40% (20/50), 70% (35/50), respectively. There were significant differences in intima-media thickening and plaque formation between groups ( χ2 = 21.83, 25.77, all P < 0.001). Logistic multivariate regression analysis showed that age ( OR = 0.953) and TG-Ab ( OR = 1.116) were independent risk factors for developing arteriosclerosis in middle-aged and older adult patients with depression ( P < 0.05). Conclusion:TG-Ab-positive results are an independent risk factor for developing arteriosclerosis in middle-aged and older adult patients with depression. TPO-Ab-positive results have a synergistic effect on the occurrence and development of arteriosclerosis in middle-aged and older adult patients with depression. Monitoring serum TG-Ab and TPO-Ab concentrations is of great clinical significance for the prevention and treatment of arteriosclerosis in middle-aged and older adult patients with depression.

Clinical efficacy of endovascular stent therapy for treatment of lower extremity atherosclerotic occlusive disease in 40 patients / 中国基层医药

Objective:To investigate the short-term and long-term efficacy of endovascular stent therapy for lower extremity atherosclerotic occlusive disease.Methods:Eighty patients with lower extremity atherosclerotic occlusive disease who received treatment in Lishui Central People's Hospital from January 2020 to January 2021 were included in this study. They were randomly divided into control and observation groups, with 40 patients in each group. The control group received lower extremity artery bypass grafting, and the observation group received endovascular stent therapy. Clinical efficacy, ankle-brachial index, claudication distance, blood flow dynamics of dorsalis artery, nerve conduction velocity of the lower extremities, and postoperative complications were compared between the two groups in the short-term and 1-year follow-ups.Results:Total response rate in the observation group was 87.5% (35/40), which was significantly higher than 67.5% (27/40) in the control group ( Z = 2.00, P < 0.05). At 1-year follow-up, total response rate in the observation group was 70.0% (28/40), which was slightly, but not significantly, higher than 47.5% (19/40) in the control group ( Z = 1.77, P > 0.05). After treatment, the ankle-brachial index and claudication distance in the observation group were significantly higher than those in the control group ( t = 3.34, 8.30, both P < 0.001). The diameter, peak velocity and blood flow of dorsal foot artery in the observation group were significantly superior to those in the control group ( t = 6.98, 4.46, 5.95, all P < 0.001). Lower extremity nerve conduction velocity in the observation group was significantly higher than that in the control group ( t = 3.01, 3.70, both P < 0.05). The incidence of postoperative complications in the observation group was slightly, but not significantly, lower than that in the control group [5.0% (2/40) vs. 15.0% (6/40), P > 0.05]. Conclusion:Compared with lower extremity artery bypass grafting, endovascular stent therapy has good short-term and long-term efficacy in the treatment of lower extremity atherosclerotic occlusive disease. Endovascular stent therapy can increase ankle-brachial index and claudication distance, improve the hemodynamic indexes of dorsalis pedis artery, increase lower extremity nerve conduction velocity and has a few complications.

Effects of a 16-week physical training on clinical outcomes in patients with hypertension and chronic kidney disease: NEPHROS post-trial follow-up / Os efeitos de um treinamento físico de 16 semanas sobre desfechos clínicos em pacientes com hipertensão e doença renal crônica: o estudo NEPHROS de seguimento pós-ensaio / Efectos de un entrenamiento físico durante 16 semanas en los resultados clínicos de pacientes afectados de hipertensión y enfermedad crónica de riñón: NEPHROS seguimiento post ensayo

The NEPHROS is a randomized controlled trial which applied a 16-week aerobic and resistance training to patients with chronic kidney disease (CKD) and high blood pressure. This report describes a long-term post-trial follow-up, comparing survival, health-related quality of life (HRQoL), and estimated glomerular filtration rate (GFR) change between the intervention and control groups according to in-trial cardiovascular risk factors. Three years after the original trial, NEPHROS participants were re-evaluated. Cox proportional hazards model was used to compare survival time and linear regression for changes in GFR and physical and mental HRQoL summary scores between intervention and control groups according to age, sex, and in-trial GFR, C-reactive protein, glucose, lipids, ankle-brachial index (ABI), functional capacity, and blood pressure. Of the 150 participants of NEPHROS, 128 were included in the long-term analysis. The previous exercise training had no effects on survival, GFR, or HRQoL. Baseline in-trial GFR (HR = 0.95, 95%CI: 0.92; 0.98) and ABI (HR = 0.03, 95%CI: 0.002; 0.43) were positive independent predictors for survival. Lower ABI (coefficient = 9.00, 95%CI: 0.43; 17.5) and higher systolic blood pressure (coefficient = -0.13, 95%CI: -0.24; -0.03) were independent predictors for GFR decline. A 16-week exercise program had no long-term effect on survival, quality of life, or glomerular filtration in patients with CKD stages 2 to 4. Lower GFR and ABI and higher systolic blood pressure were associated with poorer prognosis among CKD patients.

O estudo NEPHROS é um ensaio controlado e randomizado que aplicou um programa de treinamento aeróbico e de força com duração de 16 semanas em pacientes com doença renal crônica e hipertensão arterial. O artigo descreve o seguimento pós-ensaio de longo prazo, comparando sobrevida, qualidade de vida relacionada à saúde (HRQoL) e mudança na taxa de filtração glomerular estimada (TFGe) entre o grupo de intervenção e o grupo controle, e de acordo com fatores de risco cardiovascular registrados durante o ensaio. Os participantes do estudo NEPHROS foram reavaliados três anos depois do ensaio original. Foi usada a razão de riscos proporcionais de Cox para comparar o tempo de sobrevida, e a regressão linear para comparar a mudança na TFGe e as pontuações gerais de HRQoL física e mental, entre os grupos de intervenção e controle, de acordo com idade, sexo e níveis durante o ensaio original de TFGe, proteína C-reativa, glicose, lipídios, índice tornozelo-braquial (ITB), capacidade funcional e pressão arterial. Entre os 150 participantes do NEPHROS, 128 foram incluídos na análise de seguimento. Não foi observado nenhum efeito do treinamento na sobrevida, TFGe ou HRQoL. As medidas durante o ensaio original de TFGe (HR = 0,95; IC95%: 0,92; 0,98) e ITB (HR = 0,03; IC95%: 0,002; 0,43) foram preditores positivos independentes de sobrevida. ITB mais baixo (coeficiente = 9,00; IC95%: 0,43; 17,5) e pressão sistólica mais alta (coeficiente = -0,13; IC95% -0,24; -0.03) foram preditores independentes de declínio da TFGe. O programa de exercício de 16 semanas não teve efeito no longo prazo sobre sobrevida, qualidade de vida ou mudança na taxa de filtração glomerular em pacientes com doença renal crônica de estágios 2 a 4. Níveis mais baixos de TFGe e ITB e pressão arterial sistólica mais elevada estiveram associados a prior prognóstico entre pacientes com doença renal crônica.

NEPHROS es un ensayo controlado aleatorio que aplicó un entrenamiento de 16 semanas aeróbico y de resistencia a pacientes con enfermedad crónica de riñón y presión alta. El informe actual describe un seguimiento de largo plazo post ensayo, comparando supervivencia, calidad de vida relacionada con la salud (HRQoL) y el cambio de tasa estimada de filtración glomerular (eGFR) entre los grupos de intervención y control, y según factores de riesgo cardiovascular en el ensayo. Tras tres años del ensayo original, los participantes en NEPHROS fueron reevaluados. Se usó el modelo de Cox de riesgos proporcionales para comparar el tiempo de supervivencia y la regresión lineal para comparar el cambio en los marcadores resumen eGFR, físicos y mentales HRQoL, entre los grupos de intervención y grupos de control, y según edad, sexo, y eGFR en el ensayo, proteína C-reactiva, glucosa, lípidos, índice tobillo-brazo (ABI), capacidad funcional y presión sanguínea. De los 150 participantes de NEPHROS, 128 personas fueron incluidas en el análisis a largo plazo. No se observó un cambio en el efecto del entrenamiento físico previo en la supervivencia, eGFR o HRQoL. La base de referencia en el ensayo eGFR (HR = 0,95; 95%CI: 0,92; 0,98) y ABI (HR = 0,03; 95%CI: 0,002; 0,43) fueron predictores independientes positivos para la supervivencia. Un más bajo ABI (coeficiente = 9,00; 95%CI: 0,43; 17,5) y una presión sistólica sanguínea más alta (coeficiente = -0,13; 95%CI -0,24; -0,03) fueron predictores independientes para la disminución de la eGFR. El programa de ejercicio de dieciséis semanas no tuvo un efecto a largo plazo en la supervivencia, calidad de vida o cambio en la filtración glomerular en pacientes con etapas 2 a 4 enfermedad crónica de riñón. Una eGFR y ABI más bajos, y una presión más alta sistólica de sangre estuvieron asociadas con una prognosis más escasa entre pacientes enfermedad crónica de riñón.

High ankle-brachial index predicts cardiovascular events and mortality in hemodialysis patients with severe secondary hyperparathyroidism / Índice tornozelo-braquial elevado prediz eventos e mortalidade cardiovasculares nos pacientes em hemodiálise com hiperparatireoidismo secundário grave

Abstract Introduction: Vascular calcification related to severe secondary hyperparathyroidism (SHPT) is an important cause of cardiovascular and bone complications, leading to high morbidity and mortality in patients with chronic kidney disease (CKD) undergoing hemodialysis (HD). The present study aimed to analyze whether ankle-brachial index (ABI), a non-invasive diagnostic tool, is able to predict cardiovascular outcomes in this population. Methods: We selected 88 adult patients on HD for at least 6 months, with serum iPTH>1,000pg/mL. We collected clinical data, biochemical and hormonal parameters, and ABI (sonar-Doppler). Calcification was assessed by lateral radiography of the abdomen and by simple vascular calcification score (SVCS). This cohort was monitored prospectively between 2012 and 2019 for cardiovascular outcomes (death, myocardial infarction (MI), stroke, and calciphylaxis) to estimate the accuracy of ABI in this setting. Results: The baseline values were: iPTH: 1770±689pg/mL, P: 5.8±1.2 mg/dL, corrected Ca: 9.7±0.8mg/dL, 25(OH)vit D: 25.1±10.9ng/mL. Sixty-five percent of patients had ABI>1.3 (ranging from 0.6 to 3.2); 66% had SVCS≥3, and 45% aortic calcification (Kauppila≥8). The prospective evaluation (51.6±24.0 months), provided the following cardiovascular outcomes: 11% of deaths, 17% of nonfatal MI, one stroke, and 3% of calciphylaxis. After adjustments, patients with ABI≥1.6 had 8.9-fold higher risk of cardiovascular events (p=0.035), and ABI≥1.8 had 12.2-fold higher risk of cardiovascular mortality (p=0.019). Conclusion: The presence of vascular calcifications and arterial stiffness was highly prevalent in our population. We suggest that ABI, a simple and cost-effective diagnostic tool, could be used at an outpatient basis to predict cardiovascular events in patients with severe SHPT undergoing HD.

Resumo Introdução: A calcificação vascular relacionada ao hiperparatireoidismo secundário (HPTS) grave é uma causa importante de complicações cardiovasculares e ósseas, levando a alta morbidade e mortalidade em pacientes com doença renal crônica (DRC) em hemodiálise (HD). O presente estudo objetivou analisar se o índice tornozelo-braquial (ITB), uma ferramenta diagnóstica não invasiva, pode predizer desfechos cardiovasculares nesta população. Métodos: Selecionamos 88 adultos em HD há pelo menos 6 meses, com PTHi sérico>1.000pg/mL. Coletamos dados clínicos, parâmetros bioquímicos e hormonais, e ITB (sonar-Doppler). A calcificação foi avaliada por radiografia lateral do abdome e por escore de calcificação vascular simples (ECVS). Esta coorte foi monitorada prospectivamente entre 2012 e 2019 para desfechos cardiovasculares (óbito, infarto do miocárdio (IM), acidente vascular cerebral e calcifilaxia) para estimar a precisão do ITB neste cenário. Resultados: Os valores basais foram: PTHi: 1770±689pg/mL, P: 5,8±1,2 mg/dL, Ca corrigido: 9,7±0,8mg/dL, 25(OH)vit D: 25,1±10,9ng/Ml; 65% dos pacientes apresentaram ITB>1,3 (variando de 0,6 a 3,2); 66% tiveram ECVS≥3, e 45% calcificação da aorta (Kauppila≥8). A avaliação prospectiva (51,6±24,0 meses) forneceu os seguintes desfechos cardiovasculares: 11% de óbitos, 17% de IM não fatal, um AVC, 3% de calcifilaxia. Após ajustes, pacientes com ITB≥1,6 tiveram risco 8,9 vezes maior de eventos cardiovasculares (p=0,035), e ITB≥1,8 apresentaram risco 12,2 vezes maior de mortalidade cardiovascular (p=0,019). Conclusão: A presença de calcificações vasculares e rigidez arterial foi altamente prevalente em nossa população. Sugerimos o ITB, uma ferramenta diagnóstica simples e econômica, para ser usada em ambulatório para prever eventos cardiovasculares em pacientes com HPTS grave em HD.

Contribuição do índice tornozelo-braquial na estratificação do risco cardiovascular / Contribution of the ankle-brachial index to cardiovascular risk stratification

doença arterial periférica (DAP) desponta atualmente como a terceira maior causa de morbidade cardiovascular por doença aterosclerótica no mundo, havendo nítida associação com a doença arterial coronária (DAC) e o acidente vascular encefálico (AVE). Sendo muitas vezes a primeira manifestação da aterosclerose sistêmica, seu correto diagnóstico pode levar à reestratificação de risco cardiovascular (RCV), principalmente em pacientes assintomáticos do ponto de vista cardiológico. Surge assim o índice tornozelo-braquial (ITB), padrão-ouro para o diagnóstico não-invasivo de DAP, como exame complementar de fácil acesso, baixo custo, passível de ser realizado ambulatorialmente e com resultado objetivo e de fácil interpretação, tornando-se um método acessível para avaliação da aterosclerose sistêmica. Diversos estudos amparam seu uso como complementação ao Escore de Risco de Framingham, aumentando a acurácia do mesmo e permitindo a reestratificação de pacientes, auxiliando assim na decisão clínica do tratamento a ser instituído, ou mesmo como fator de RCV isolado.

Peripheral arterial disease (PAD) is currently the third leading cause of cardiovascular morbidity from atherosclerotic disease in the world, with a clear association with coronary artery disease (CAD) and stroke. As it is often the first manifestation of systemic atherosclerosis, its correct diagnosis can lead to cardiovascular risk (CVR) restratification, especially in asymptomatic cardiac patients. Thus, the ankle-brachial index (ABI), the gold standard for the non-invasive diagnosis of PAD, appears as a complementary exam that is easily accessible, low cost, capable of being performed in an outpatient clinic and with an objective and easy-to-interpret result, being an accessible method for assessing systemic atherosclerosis. Several studies support its use as a complement to the Framingham Risk Score, increasing its accuracy and allowing the restratification of patients, thus assisting in the clinical decision of the treatment to be instituted, or even as an isolated CVR.

Pesquisa de enfermedad arterial periférica asintomática en pacientes con diabetes mellitus tipo 2 / Screening for asymptomatic peripheral artery disease in patients with type 2 diabetes mellitus

Introducción: La diabetes mellitus modifica la historia natural de la aterosclerosis. Por ello, la repercusión de este proceso en los diferentes lechos vasculares constituye la principal causa de morbimortalidad en estos pacientes. Objetivos: Determinar la frecuencia de enfermedad arterial periférica asintomática en personas con diabetes mellitus tipo 2, su relación con otras variables clínicas de la diabetes y las complicaciones de la enfermedad. Métodos: Se realizó un estudio descriptivo transversal en el policlínico Cerro con un total de 100 pacientes diabéticos tipo 2 en edades comprendidas entre 40 y 70 años en el período de un año (2019), sin diagnóstico previo de enfermedad arterial periférica ni lesiones en los pies. Se examinaron los pulsos periféricos de miembros inferiores y se calculó el índice de presiones tobillo-brazo. Resultados: Se identificaron 36 pacientes con índices bajos, lo que fue consistente con una enfermedad arterial periférica asintomática (36 por ciento). El tabaquismo se relacionó de forma significativa con la presencia de índices bajos (p = 0,02), pero no hubo diferencias significativas con respecto a la edad, el sexo, el color de la piel, el tiempo de evolución de la diabetes, el consumo de bebidas alcohólicas, la actividad física, la hipertensión arterial y la obesidad. La mayoría de los pacientes tuvo una afectación ligera en cuanto a la severidad. Conclusiones: La enfermedad arterial periférica asintomática es una complicación frecuente en las personas con diabetes de tipo 2(AU)

Introduction: Diabetes mellitus modifies the natural history of atherosclerosis. Therefore, the impact of this process on the different vascular beds is the main cause of morbidity and mortality in these patients. Objectives: Determine the frequency of asymptomatic peripheral artery disease in people with type 2 diabetes mellitus, its relationship with other clinical variables of diabetes and complications of the disease. Methods: A cross-sectional descriptive study was conducted at Cerro polyclinic with a total of 100 type 2 diabetic patients aged between 40 and 70 years in a period of one year (2019), without prior diagnosis of peripheral arterial disease or foot injuries. Peripheral pulses of the lower limbs were examined and the ankle-brachial pressure index was calculated. Results: 36 patients with low rates were identified, which was consistent with asymptomatic peripheral arterial disease (36 percent). Smoking habit was significantly related to the presence of low rates (p = 0.02), but there were no significant differences with respect to age, sex, skin color, time of evolution of diabetes, consumption of alcoholic beverages, physical activity, high blood pressure and obesity. Most patients had a slight affectation regarding severity. Conclusions: Asymptomatic peripheral artery disease is a common complication in people with type 2 diabetes(AU)

Role of ankle brachial index measured by simple automatic sphygmomanometers in predicting postoperative kidney function in patients undergoing major cardiac surgery / El papel del índice tobillo-brazo medido mediante un esfigmomanómetro automático para pronosticar la función renal posoperatoria en pacientes que se sometieron a una cirugía cardíaca mayor

Abstract Introduction: Ankle-brachial pressure index is an objective, noninvasive test for predicting subclinical atherosclerotic diseases. We investigated the role of ankle-brachial pressure index measured with automated sphygmomanometer devices in the prediction of the development of acute kidney injury in patients undergoing major cardiac surgery. Methods: This single-centered, cross-sectional, and observational study was performed on 80 (66 males and 14 females, 58 ± 10 years) patients undergone cardiac surgery. Complete anamnesis, laboratory tests, intravenous fluids, medications, blood products, and all perioperative procedures were recorded in all patients before the surgery. Two automated sphygmomanometer devices giving equivalent results were used for measuring Ankle-brachial pressure index. The data in the first two days after the surgery were used for analysis. The criteria of AKIN were used in the diagnosis of acute kidney injury. Results: Twenty-one (23%) patients developed acute kidney injury in the postoperative period. None of the patients needed renal replacement therapy or died. There was no significant difference between mean ankle-brachial pressure index levels of patients with and without acute kidney injury (1.04 ± 0.17 and 1.06 ± 0.19, respectively, p=0.554). The mean ankle-brachial pressure index was significantly lower in patients with perioperative complications that cause hemodynamic instability (1.07 ± 0.14, 0.96 ± 0.13, p=0.016). On the multivariate analysis model, only perioperative hemodynamic complication development was found to be related to postoperative acute kidney injury. Conclusion: Ankle-brachial pressure index may have a role in predicting perioperative hemodynamic complications, which may cause acute kidney injury in patients undergoing major surgery. Simple automatic blood pressure devices can be used in daily practice for ankle-brachial pressure index measurement instead of complex and expensive doppler devices.

Resumen Introducción: El índice tobillo-brazo (ITB) es una prueba objetiva y no invasiva para diagnosticar la aterosclerosis asintomática. Investigamos el papel del índice tobillo-brazo medido a través de esfigmomanómetros automáticos para pronosticar el desarrollo de insuficiencia renal aguda en pacientes que se sometieron a una cirugía cardíaca mayor. Material y métodos: En este estudio observacional, transversal y unicéntrico, se incluyó a 80 pacientes (66 hombres y 14 mujeres de 58 ± 10 años) que se sometieron a una cirugía cardíaca. Se registraron los siguientes datos de todos los pacientes antes de la cirugía: anamnesis completa, análisis clínicos, líquidos intravenosos, medicamentos, productos hemoderivados e intervenciones perioperatorias. Para medir el ITB, se utilizaron dos esfigmomanómetros automáticos que arrojaron resultados similares. Se analizaron los datos recogidos los primeros dos días luego de la cirugía. Se siguieron los criterios de la AKIN para diagnosticar la insuficiencia renal aguda. Resultados: Veintiún pacientes (23 %) sufrieron insuficiencia renal aguda en el postoperatorio. Ninguno de los pacientes necesitó tratamiento renal sustitutivo ni falleció. No hubo diferencias significativas entre los valores medios del índice tobillo-brazo en pacientes con insuficiencia renal aguda y sin ella (1,04 ± 0,17 y 1,06 ± 0,19, respectivamente; p=0,554). El valor medio del ITB fue significativamente menor en pacientes con complicaciones perioperatorias que causan inestabilidad hemodinámica (1,07 ± 0,14; 0,96 ± 0,13; p=0,016). En el modelo de análisis multivariado, solo se encontró que la aparición de complicaciones hemodinámicas perioperatorias estaba relacionada con la insuficiencia renal aguda luego de la operación quirúrgica. Conclusión: Es posible que el ITB desempeñe un papel en la predicción de complicaciones hemodinámicas perioperatorias, que pueden causar insuficiencia renal aguda en pacientes sometidos a cirugía mayor. En la práctica diaria, pueden utilizarse dispositivos automáticos simples que calculan la tensión arterial para medir el índice tobillo-brazo, en lugar de dispositivos Doppler complejos y costosos.

Índice tobillo-brazo obtenido mediante fotopletismografía como marcador de insuficiencia arterial periférica asintomática en pacientes prehipertensos

RESUMEN Introducción: La enfermedad arterial periférica (EAP) puede presentarse de forma asintomática, de ahí la necesidad de su diagnóstico para evitar complicaciones. Objetivo: Determinar la presencia de enfermedad arterial periférica mediante el índice tobillo-brazo obtenido por fotopletismografía en pacientes prehipertensos. Método: Se realizó un estudio descriptivo de corte transversal, en un universo constituido por los 35 pacientes mayores de 18 años, con diagnóstico presuntivo de prehipertensión arterial, del Consultorio 2 perteneciente al Policlínico Universitario Josué País García de Santiago de Cuba. Para medir el índice tobillo-brazo se empleó el pletismógrafo digital ANGIODIN® PD 3000. Resultados: El 100% de los pacientes carecía de síntomas de EAP, pero al realizar la medición del índice tobillo-brazo se encontró que el 51,43% de ellos tenía signos de esta enfermedad. La EAP fue más frecuente en hombres (52,94 vs. 50,0%), sin que se encontraran diferencias estadísticas significativas (p>0,05). Conclusiones: El índice tobillo-brazo obtenido mediante fotopletismografía resultó útil para determinar la presencia de enfermedad arterial periférica asintomática en pacientes prehipertensos. Se identificó una alta incidencia de la enfermedad, con mayor frecuencia en el sexo masculino.

ABSTRACT Introduction: Peripheral artery disease (PAD) may present with no symptoms at all, hence the need for diagnosis to avoid complications. Objective: To determine the presence of peripheral artery disease by means of the ankle-brachial index obtained by photoplethysmography in prehypertensive patients. Method: A descriptive cross-sectional study was carried out in a population of 35 patients over 18 years of age, with a presumptive diagnosis of prehypertension, belonging to the Family Doctor's Office 2 from the Policlínico Universitario Josué País García in Santiago de Cuba. The ANGIODIN® PD 3000 digital plethysmograph was used to measure the ankle-brachial index. Results: None of the patients had symptoms of PAD, but after measuring the ankle-brachial index, 51.43% of them were found to have signs of this disease. Peripheral artery disease was more frequent in men (52.94 vs. 50.0%), with no significant statistical differences (p>0.05). Conclusions: The ankle-brachial index obtained by photoplethysmography was useful in determining the presence of asymptomatic peripheral artery disease in prehypertensive patients. A high incidence of the disease was identified, with a higher frequency in the male sex.
