Type 1C Multiple Symmetrical Lipomatosis: A Cause of Misdiagnosis in Females.

Multiple symmetrical lipomatosis (MSL) is a disease that causes symmetrical fat deposits in the neck, shoulders, and upper trunk. It is more common in the neck area in men who consume alcohol. The male-to-female ratio varies from 15:1 to 30:1. Madelung's disease has been reported in a small number of female patients who do not consume alcohol. Pseudoathletic appearance (MSL type 1C) is rare and causes misdiagnosis. We would like to present a 50-year-old woman with an athletic appearance who had fat deposits on her shoulders and upper chest. After excluding obesity and Cushing's syndrome, which were initially considered, we aimed to remind people of this entity that causes symmetrical fat deposits in the upper trunk in females.

Role of basal autonomic functions in patients with increased morning blood pressure surge.

BACKGROUND: Morning blood pressure (BP) surge (MS) is associated with cardiovascular events. The autonomic nervous system plays an active role in the regulation of BP and its function can be evaluated by heart rate variability (HRV) analysis. This study aimed to evaluate autonomic nervous system functions in patients with increased MS. METHODS: Patients who underwent ambulatory BP monitoring (ABPM) and 24-h rhythm Holter in our hospital during the same period between 2017 and 2022 were evaluated. HRV parameters were obtained from 24-h rhythm Holter recordings. MS values of the patients were calculated from ABPM records and patients were divided into four groups according to the MS quartiles. HRV parameters and other parameters were compared between the groups. RESULTS: A total of 129 patients were included in the study. The mean age of the patients was 57.2 ± 18.2 years, and 63 (48.8%) were male. HF, the square root of the mean squared differences of successive normal-to-normal intervals (rMSSD), and the proportion of adjacent RR intervals differing by >50 ms in the 24-h recording (pNN50) were statistically significant between the groups ( P = 0.039, P = 0.013, P = 0.011, respectively). In univariate regression analysis, low-frequency/high-frequency ratio was positively associated with MS and HF, SDNNi, rMSSD, and pNN50 were negatively associated ( ß = 0.207, P = 0.019; ß = -0.272, P = 0.002; ß = -0.201, P = 0.022; ß = -0.265, P = 0.002; ß = -0.278, P = 0.001, respectively). Multiple linear regression analysis showed an independent association between HF, low-frequency/high-frequency ratio, rMSSD, pNN50, and MS ( ß = -0.247, P = 0.005; ß=0.206, P = 0.017; ß = -0.209, P = 0.005; ß = -0.227, P = 0.008, respectively). CONCLUSION: We found an independent association between HRV parameters associated with vagal tone and MS. The findings of our study suggest that the increased sympathetic activity detected in patients with high MS in previous studies may be due to a decrease in basal vagal tone.

Evaluation of the relationship between para-aortic adipose tissue and ascending aortic diameter using a new method.

BACKGROUND: Para-aortic adipose tissue (PAT) is the local adipose tissue that externally surrounds the aorta. It contributes significantly to aortic atherosclerosis and enlargement. Studies conducted with computed tomography and magnetic resonance have shown that individuals with aortic aneurysm had more PAT than healthy individuals. In this study, we measured PAT using transthoracic echocardiography (TTE). The aim of this study is to investigate the possible relationship of TTE measured PAT with ascending aortic width. METHODS: PAT was defined as the hypoechoic space in front of ascending aortic 2 cm above the sinotubular junction at the end of the systole. Patients were divided into 2 groups according to the presence of dilatation in the ascending aorta using Roman's classification (aortic size index, ASI). ASI of less than 21 was considered no aortic dilation and an ASI of 21 mm/m2 or greater was considered to have aortic dilation. RESULTS: A total of 321 unselected patients were divided into the ascending aortic dilatation (AAD) group (n = 96) and the normal ascending aorta diameter group (n = 225 patients). PAT was significantly higher in the AAD group compared with the non-ADD group (0.9 (0.48) vs. 0.7 (0.91) mm, p < 0.0001). Univariate and multivariate logistic regression analysis revealed that PAT (OR: 3.005, 95%CI (1.445-6.251)) were significantly associated with AAD. CONCLUSIONS: This is the first study which evaluated PAT measured by TTE. We found a significant association between PAT measured by TTE and ascending aorta width.

In-Hospital Bleeding and Mortality in Acute Coronary Syndrome Patients Treated with Tirofiban and Potent P2Y12 Inhibitors.

OBJECTIVE: In this study, we aimed to determine whether potent agents affect in-hospital bleeding and mortality compared to clopidogrel in patients with the acute coronary syndrome in whom tirofiban and P2Y12 inhibitor are used together. METHODS: Patients who were treated interventionally between 2015 and 2020 and were using tirofiban were retrospectively screened. Clinical, laboratory, and angiographic findings were obtained from the hospital database. Patients were analyzed by dividing them into clopidogrel and prasugrel/ticagrelor groups. RESULTS: Acute coronary syndrome patients (n = 227) who were treated interventionally were included in this retrospective study. Clopidogrel was given to 93 (41%), ticagrelor to 112 (49.3%), and prasugrel to 22 of the patients (9.7%). Compared to the ticagrelor/prasugrel group, the clopidogrel group was older and more were women, and the history of hypertension and previous coronary artery disease was higher (P, respectively: <.001; .001; .008; .0045). The creatinine value was higher, the basal hemoglobin was lower, and the GRACE (Global Registry of Acute Coronary Events) and CRUSADE (Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHA Guidelines) scores were higher (P, respectively: .026; .002; .002; <.001). The in-hospital bleeding rate was signifi- cantly higher in the clopidogrel group (P < .001). Although the in-hospital mortality rate was higher, it was not statistically significant (P = .07). Regression analysis showed that GRACE score and gender were associated with in-hospital mortality (P < .001; P=.031, respectively), and only age was associated with in-hospital bleeding (P < .001). No relationship was found with P2Y12 inhibitor. CONCLUSION: In our study, we found that the combined use of potent P2Y12 inhibitor with tiro- fiban in acute coronary syndrome patients treated interventionally was not different from the use of clopidogrel in terms of in-hospital bleeding and mortality.

Association of the Atherogenic Index of Plasma with C-Reactive Protein and Urinary Albumin Excretion in a Normotensive Nondiabetic Population.

Background: The atherogenic index of plasma (AIP) is an indicator of atherogenic dyslipidemia and is significantly associated with the development of atherosclerotic cardiovascular disease. Previous studies showing the association of AIP with C-reactive protein (CRP) and microalbuminuria included hypertensive and diabetic patients. We aimed to determine the association of AIP with CRP and albuminuria in a normotensive and nondiabetic population. Methods: The study was conducted retrospectively. Two hundred thirty-three individuals without hypertension, diabetes, cardiovascular disease, malignancy, systemic inflammatory disease, nephrological disease, and active infection were determined and included in the study. Urinary albumin excretion was calculated from the albumin-creatinine ratio in fresh spot urine [urinary albumin-creatinine ratio (UACR)]. AIP risk groups were compared in terms of clinical and laboratory findings, and the correlation between AIP and CRP and UACR was evaluated. Results: A total of 233 people, with a mean age of 45.4 years and 139 (69.7%) of whom were male, were included in the study. One hundred thirty-eight (59.2%) individuals were found to be in the low-risk group, 29 (12.5%) in the medium-risk group, and 66 (28.3%) in the high-risk group, according to the AIP value. CRP and UACR were not different between the AIP risk groups (P: 0.141 and 0.441, respectively). A mild correlation was found between AIP and CRP (r: 0.192; P: 0.003), but no correlation was found between AIP and UACR (r: 0.086; P: 0.193). The stepwise linear regression analysis with model adjusted for possible confounders and AIP revealed that only body mass index was a significant predictor of CRP (ß: 0.308; P < 0.001), while only systolic blood pressure was a significant predictor of UACR (ß: 0.19; P: 0.004), but AIP was not. Conclusions: AIP was not associated with CRP and UACR in normotensive and nondiabetic individuals. This finding suggests that the relationship found in previous studies is related to the presence of hypertension or diabetes rather than the AIP.

Association of Morning Surge and Postexercise Heart Rate and Blood Pressure Recovery.

INTRODUCTION: The autonomic nervous system plays an active role in the regulation of early morning blood pressure (BP) and BP/pulse regulation in the treadmill exercise test (TET). AIM: We evaluated the relationship between BP/pulse changes during TET and morning blood pressure surge (MS). METHODS: Patients who underwent ambulatory blood pressure measurement (ABPM) and TET in the same visit between 2017 and 2020 were evaluated retrospectively. Patients with previously diagnosed hypertension and/or using antihypertensives and office BP ≥ 140/90 were excluded from the study.MS values and dipping percentage were calculated from ABPM data. The patients were analyzed by dividing them into two groups according to the MS median, and BP/pulse values during exercise and recovery periods were compared in these groups. RESULTS: 202 patients [median age 45 (39-51), male 134 (66.3%)] were included in the study. MS median was 18.5 (10.75-27) mmHg. TET recovery period 3rd-min systolic blood pressure (RSBP) was higher in the group with high MS (p: 0.017). Systolic and diastolic dipping percentages were higher in the group with higher MS (p: 0.015, p: 0.040, respectively). Peak systolic and diastolic BP, RSBP, and recovery 3rd min diastolic BP were positively correlated with MS (p < 0.05, for all). Additionally, an independent relationship was observed between RSBP and MS (ß: 0.205, p: 0.028). CONCLUSION: We found an independent association between RSBP and MS. Increased RSBP may be associated with target organ damage and cardiovascular events such as MS.

A new and simple parameter for diagnosis pulmonary edema: Expiratory air humidity.

PURPOSE: Acute pulmonary edema is characterized by increased levels of fluid in the interstitial and alveolar space of the lung and requires emergency treatment. In acute pulmonary edema, the amount of fluid in the intra-alveolar, interstitial space, and pleural space vary considerably and this fluid will evaporate in different amounts compared to the physiological fluid. The aim of this study was to compare the humidity rates of expiratory air measured before and after pulmonary edema induced by α-naphthylthiourea (ANTU) in rats. METHODS: The study included twenty healthy adult rats divided equally into a healthy control group and a pulmonary edema group. Pulmonary edema was induced by administering ANTU intraperitoneally in the rats in the study group. Humidity, temperature, lung weight, pleural effusion, and histopathological changes in the respiratory system due to pulmonary edema were examined in the ANTU group. Control measurments were taken before administration of ANTU and again 4 h after administration of ANTU when lung damage was considred to be at maximum levels. RESULTS: Mean expiratory air humidity was 71.22±3.59% before ANTU and 56.28±3.94% after administration of ANTU. The mean humidity difference of -14.94±5.96% was considered statistically different (p = 0.01). CONCLUSION: Humidity rate in expiratory air was significantly lower in rats with acute pulmonary edema compared to healthy rats. This result supports the hypothesis that humidity in expiratory air can be considered an important parameter in patients during clinical are follow-up for pulmonary edema.

New perspective on fatigue in hemodialysis patients with preserved ejection fraction: diastolic dysfunction : Fatigue and diastolic dysfunction.

The relationship between diastolic dysfunction and fatigue in hemodialysis patients with preserved ejection fraction is unknown. In this context, the objective of this study is to assess fatigue using the relevant scales and to demonstrate its relationship with diastolic dysfunction. The patients who underwent hemodialysis were evaluated prospectively. Patients' fatigue was assessed using the Visual Analogue Scale to Evaluate Fatigue Severity (VAS-F). The echocardiographic works were performed as recommended in the American Society of Echocardiography guidelines. A total of 94 patients [mean age 64.7 ± 13.5 years, 54 males (57.4%)] were included in the study. The median VAS-F score of these patients was 68.5 (33.25-91.25), and they were divided into two groups according to this value. Peak myocardial velocities during early diastole (e') and tricuspid annular plane systolic excursion (TAPSE) values were found to be significantly lower in the group with high VAS-F scores, whereas the early diastolic flow velocities (E)/e' ratio and pulmonary artery peak systolic pressures (PAP) were found to be significantly higher (p < 0.05, for all). E/e' ratio (r 0.311, p 0.002) and PAP (r 0.281, p 0.006) values were found to be positively correlated with the VAS-F score, as opposed to the TAPSE (r - 0.257, p 0.012) and e' (r - 0.303, p 0.003) values, which were found to be negatively correlated with the VAS-F score. High fatigue scores in hemodialysis patients may be associated with diastolic dysfunction. In addition, in our study, we determined the correlation of VAS-F score with E/e' ratio, PAP and TAPSE.

Heart rate variability and heart rate turbulence in patients with vasovagal syncope.

Aim    The autonomic nervous system plays an important role in the pathogenesis of vasovagal syncope, but studies on the effect of basal autonomic tone have found confusing results. The aim of this study was to investigate the effect of basal autonomic functions, as assessed by heart rate variability (HRV) and heart rate turbulence (HRT), in patients with vasovagal syncope.Material and methods    Patients who underwent head-up tilt test (HUTT) due to unexplained syncope and who had a 24 hr Holter ECG recording in the same period were retrospectively analyzed. Patients with diabetes, a history of myocardial infarction, heart failure, orthostatic hypotension, atrial fibrillation, or use of vasoactive drugs, such as beta blockers, were excluded from the study. 161 patients who met these criteria were included in the study. Time domain HRV parameters from Holter ECG recordings and HRT parameters from patients with sufficient number of ventricular premature contractions were measured.Results    The age of the patients varied from 16 to 75 yrs (mean: 44.8±18.5 yrs). HUTT results of 60 (37.2 %) patients were evaluated as positive. There were no significant differences in the basal demographic, clinical, or laboratory findings of the tilt-positive and tilt-negative patient groups. Likewise, there were no significant differences between the time domain HRV parameters and HRT parameters of both groups.Conclusion    HRV and HRT parameters reflecting basal autonomic function were not different between HUTT positive and HUTT negative patient groups. These findings suggest that basal autonomic functions have no effect on vasovagal syncope pathogenesis.

Determinants of reverse dipping blood pressure in normotensive, non-diabetic population with an office measurement below 130/85mmHg.

Objective: The role of dipping blood pressure pattern in normotensives is unclear. The study aims to search the circadian blood pressure rhythm and the clinical determinants related to reverse dipping pattern in a strictly selected, normotensive population.Methods: The study population was divided into three groups depending on the nocturnal dipping pattern as dipping, non-dipping, and reverse dipping. Basal clinical characteristics, anthropometric measurements, and spot urine samples from the first-morning void were collected. Clinical determinants related to the presence of reverse dipping pattern were tested by the Multiple Binary Logistic Regression analysis.Results: A total of 233 participants were involved in the study population (median age 45 years [40-50]). Dipping pattern was detected in 55.4%, non-dipping pattern in 33.0%, and reverse dipping pattern in 11.6% of the study population. There was no difference between the groups in terms of basal clinical features. Albumin-to-creatinine ratio (ACR) (p < .001) and hs-CRP levels (p = .006) were also statistically significant across the groups. ACR (HR: 1.195, 95% CI: 1.067-1.338, p = .002) and hs-CRP (HR: 2.438, 95% CI: 1.023-5.808, p = .044) were found to be related to the presence of reverse dipping blood pressure pattern.Conclusions: The absence of nocturnal physiological dipping is seen at a remarkable rate in the normotensive Turkish population. ACR and hs-CRP are the clinical determinants related to the presence of reverse dipping blood pressure pattern.

Which is responsible for target organ damage in masked hypertension? Is it an increase in blood pressure or a disruption of the circadian rhythm?

OBJECTIVE: Masked hypertension (MH) and non-dipping pattern are conditions associated with target organ damage and cardiovascular risk, which are frequently observed together. We aimed to show the relationship between the target organ damage observed in MH and the deterioration in the dipping pattern. METHODS: Patients who underwent ambulatory blood pressure monitoring (ABPM) and office blood pressure (BP) <140/90 mmHg were retrospectively screened. In ABPM data, those with daytime BP ≥135/85 mmHg and night BP ≥120/70 mmHg were included in the MH group, while the others were included in the normotensive group. The patients were grouped as dipper, non-dipper and reverse-dipper according to ABPM results. Left ventricular mass index (LVMI), glomerular filtration rate (GFR) and serum creatinine levels were used to determine target organ damage. RESULTS: 289 patients [mean age 46.6 ± 12.4 years, 136 (47.1%) males], 154 (53.3%) of whom had MH were included in our study. GFR value was found to be significantly lower, serum creatinine levels and LVMI were significantly higher in patients with MH compared to normotensives (p < .05, for all). When the subgroups were examined, it was found that this difference was associated with the disruption in the dipping pattern. In patients with MH, dipping pattern disruption without change in systolic BP was independently associated with an increase in LVMI (p < .05, for both). CONCLUSION: Target organ damage seen in MH may be due to the deterioration of the dipping pattern.

Aortic arch calcification: a novel parameter for prediction of masked hypertension.

BACKGROUND: Masked hypertension is directly related to increased cardiovascular morbidity and mortality but remains underdiagnosed in clinical practice. The aim of the study was to search the role of aortic arch calcification (AAC) in the diagnosis of masked hypertension. METHODS AND RESULTS: Among the patients who underwent ambulatory blood pressure monitoring (ABPM) in our clinic, those with office blood pressure (OBP) <140/90 mmHg were included in the study population. According to OBP, they were divided into two groups as normal (<130/85 mmHg) and high normal (130-139/85-89 mmHg) OBP groups. Subjects were also investigated for the presence of masked hypertension with ABPM and searched in masked hypertension and control groups. Masked hypertension was defined as in the latest 2017 ACC/AHA Hypertension guideline and was diagnosed as the daytime BP ≥ 135/85 mmHg and nighttime BP ≥ 120/70 mmHg. AAC was evaluated on direct X-ray telecardiography. Diagnosis of masked hypertension was searched depending on the presence of AAC and OBP measurements as well. A total of 216 volunteers were involved in the study [mean age 45.2 ± 12.2 years; female gender 120 (55.5%)]. One hundred ten volunteers (50.9%) had masked hypertension according to the ABPM. AAC was significantly more common in the masked hypertension group (44.5% vs. 26.4%) (P = 0.005). AAC had a positive predictive value of 79% in those with high normal OBP in the diagnosis of masked hypertension, and also AAC had a negative predictive value of 74% in those with normal OBP. CONCLUSION: AAC can be used as a reliable diagnostic tool to exclude and predict masked hypertension during office examination.

Aortic Arch Calcification on Routine Chest Radiography is Strongly and Independently Associated with Non-Dipper Blood Pressure Pattern / A Calcificação no Arco Aórtico na Radiografia de Tórax de Rotina está Forte e Independentemente Associada ao Padrão Não-Dipper de Pressão Arterial

Abstract Background: Non-dipper blood pressure (NDBP) is one of the important causes of hypertension-related target organ damage and future cardiovascular events. Currently, there is no practical tool to predict NDBP pattern. Objectives: The aim of this study was to investigate the relationship between aortic arch calcification (AAC) on chest radiography and NDBP pattern. Methods: All patients referred for ambulatory BP monitoring test were approached for the study participation. NDBP was defined as the reduction of ≤10% in nighttime systolic BP as compared to the daytime values. AAC was evaluated with chest radiography and inter-observer agreement was analyzed by using kappa statistics. Univariate and multivariate logistic regression analysis was conducted to assess the association of AAC and NDBP pattern. A 2-tailed p-value < 0.05 was considered statistically significant. Results: A total of 406 patients (median age: 51.3) were included. Of these, 261(64%) had NDBP pattern. Overall, the prevalence of AAC was 230 (57%). Non-dipper group had significantly higher prevalence of AAC (70% vs. 33%, p < 0.0001) as compared to the dipper group. Presence of AAC was a strong and independent predictor of NDBP pattern (OR 3.919, 95%CI 2.39 to 6.42) in multivariate analysis. Conclusions: Presence of AAC on plain chest radiography is strongly and independently associated with the presence of NDBP pattern.

Resumo Fundamento: A pressão arterial não-dipper é uma das causas mais importantes de lesão de órgão-alvo da hipertensão e de eventos cardiovasculares futuros. Atualmente, não há uma ferramenta prática para prever o padrão não-dipper de pressão arterial. Objetivos: O objetivo deste estudo foi investigar a relação entre a calcificação no arco aórtico detectada no raio de tórax e o padrão não-dipper de pressão arterial. Métodos: Todos os pacientes encaminhados para monitorização ambulatorial da pressão arterial foram abordados para participação no estudo. A pressão arterial não-dipper foi definida como a redução de ≤10% da pressão arterial sistólica noturna quando comparada com os valores diários. A calcificação no arco aórtico foi avaliada através de radiografia do tórax e a concordância interobservador foi analisada utilizando a estatística kappa. Análises de regressão logística uni e multivariada foram realizadas para avaliar a associação entre a calcificação no AA e o padrão PADV. Valores de p bicaudais < 0,05 foram considerados estatisticamente significativos. Resultados: Ao todo, 406 pacientes (idade mediana: 51,3) foram incluídos. Desses, 261(64%) apresentavam padrão não-dipper de pressão arterial. De modo geral, a prevalência de calcificação no arco aórtico foi de 230 (57%). O grupo não-dipper apresentou prevalência significativamente maior de calcificação no arco aórtico (70% vs. 33%, p < 0,0001) em relação ao grupo dipper. A presença de calcificação no arco aórtico foi um preditor forte e independente de padrão não-dipper de pressão arterial (OR = 3,919; IC: 95% 2,39-6,42) em análise multivariada. Conclusões: A presença de calcificação no arco aórtico em raio-x de tórax simples está forte e independentemente associada à presença de padrão não-dipper de pressão arterial.

Fibulins: a new biomarker for pulmonary thromboembolism?

OBJECTIVES: Fibulin-1, -2, -4, and -5 have important role in several vascular diseases. We aimed to investigate if fibulin-4 and -5 can be used as a biomarker for pulmonary thromboembolism (PTE). METHODS: This is a prospective case control study. Thirthy patients diagnosed with PTE and 31 in the control group. Data on demographic characteristics, length of hospital stay, blood cell counts, troponin and BNP levels, arterial blood gases, radiological reports, indication for thromboembolitic treatment, intensive care unit (ICU) requirement, and loss of life were recorded for the patients group. Serum Fibulin-4 and Fibulin-5 levels were measured. RESULTS: Fibulin 4 levels correlated positively with female gender (p < .01, r = 0.433). Positive results were found in 14 (46.7%) patients for PESI.0.1; in 7 (23.3%) patients for D-dimer; in 7 (23.3%) patients for troponin-I; in 7(23.3%) patients for BNP. Median values for Fibulin 4 level were significantly higher in patients positive for BNP. Fibulin-5 level was found to be correlated with the presence of embolism (p = .041, r = 0.263). CONCLUSIONS: Fibulin-4 and -5 have been shown to be relevant to cardiovascular biology and diseases. Experimental studies and observations in humans show that they may play a role in several cardiovascular diseases particularly pulmonary embolism.

The Relationship Between Obstructive Sleep Apnea and Coronary Plaque: A Coronary Computed Tomographic Angiography Study.

BACKGROUND: Coronary artery disease continues to be the most important cause of morbidity and mortality. Obstructive sleep apnea (OSA) is independently associated with subclinical atherosclerosis. In this study, we aimed to assess the relationship between the presence of coronary plaques and OSA and between coronary plaque burden and the severity of OSA according to plaque type. METHODS: In this cross-sectional study, we enrolled 214 consecutive patients who were divided into four groups of 43 patients (age: 52.3 ± 6.4 years) without OSA, 51 patients (age: 53.9 ± 6.7 years) with mild OSA, 40 patients (age: 55.2 ± 5.9 years) with moderate OSA, and 80 patients (age: 54.9 ± 7.2 years) with severe OSA according to the apnea-hypopnea index (AHI). We performed coronary computed tomographic angiography (CCTA) and evaluated plaque positivity, the presence of non-calcified/mixed plaques, and total stenosis score for each group. RESULTS: The prevalence of non-calcified/mixed plaques was three times higher in the severe OSA (41.3%) group and two times higher in the moderate OSA (30.0%) group compared to the patients without OSA (14.0%). When the four groups were examined in terms of plaque burden, the total stenosis score was found to increase with the presence and severity of OSA (0.27 ± 0.85, 1.07 ± 2.44, 1.75 ± 2.85, and 2.55 ± 3.96 respectively, p = 0.001). In addition, AHI and age were independent predictors of the presence of non-calcified/mixed plaques (p < 0.001 and p = 0.007, respectively). CONCLUSIONS: The presence of coronary artery plaques, especially non-calcified/mixed plaques, and coronary artery stenosis as measured by CCTA was significantly associated with the severity of sleep-disordered breathing in symptomatic patients at low to intermediate risk of coronary artery disease. Prospective studies are needed to establish the relationship between plaque burden and OSA.

A strong and reliable indicator for early postoperative major cardiac events after elective orthopedic surgery: Aortic arch calcification.

BACKGROUND: Cardiovascular events after orthopedic surgery may result in mortality. Therefore, predictors of early cardiovascular events after elective orthopedic surgery are required. AIM: The aim of this study is to investigate the relationship between aortic arch calcification and 30-day major adverse cardiac events following elective orthopedic surgery. METHODS: Patients who had undergone orthopedic surgery were screened. Preoperative detailed anamnesis was taken. Echocardiography and standard chest x-ray were performed.Patients were followed in terms of perioperative 30-days major cardiac events and were classified into two groups according to development of perioperative major adverse cardiac events.Aortic arch calcification was evaluated by two cardiologists, blinded to study findings and was graded as 0 to 3 on chest x-ray. RESULTS: A total of 1060 patients were approached for the study participation. Of these 714 were included in the study (mean age: 70.43, 65% female). Cardiovascular events occurred in 33 patients. As compared to the patients without cardiac events, the prevalence of aortic arch calcification, coronary artery disease, hypertension, and smoking were higher in patients with cardiac events. In addition, Lee index, left ventricular end-systolic, end-diastolic and left atrial diameter were significantly higher, GFR values were significantly lower in the group with cardiac events.Multivariate regression analysis showed that smoking (OR 5.031, 95% CI 1.602 to 15.794), presence of hypertension (OR 5.133, 95% CI 1.297 to 20.308) and aortic arch calcification (OR 6.920, 95% CI 3.890 to 12.310) are independent predictors of major cardiac events within 30-day of elective orthopedic surgery. CONCLUSIONS: Presence of aortic arch calcification is associated with development of major cardiac events within 30-days after elective orthopedic surgery.

Does contrast media volume affect long-term survival in patients with chronic kidney disease?

INTRODUCTION: The aim of this study was to investigate the relationships between survival and related features in patients with chronic kidney disease undergoing cardiac catheterization and coronary angiography. MATERIAL AND METHODS: Three hundred and seven consecutive patients with an estimated glomerular filtration rate (e-GFR) less than 60 ml/min/1.73 m2 undergoing coronary angiography were enrolled in the study. The study population was pursued with a median follow-up duration of 41.5 months. RESULTS: In the Cox proportional hazards regression model, age (HR = 1.047, 95% CI: 1.011-1.084, p = 0.01), contrast media volume (HR = 1.004, 95% CI: 1.001-1.007, p = 0.008), angiotensin II receptor blocker (ARB) use (HR = 0.485, 95% CI: 0.261-0.901, p = 0.02), and e-GFR (HR = 0.978, 95% CI: 0.940-1.016, p = 0.04) were found to be independent predictors of long-term all-cause mortality. The survival analysis showed that the long-term all-cause mortality rate was higher in patients using contrast media volume greater than 140 ml compared to patients given less than or equal to 140 ml during the coronary angiography (3.6% vs. 11.6% log-rank, p = 0.001). CONCLUSIONS: In patients with chronic kidney disease undergoing cardiac catheterization, age, contrast media volume, e-GFR and low ARB use were found to be independent predictors of long-term all-cause mortality. Contrast media volume used > 140 ml was independently associated with long-term all-cause mortality compared to less than or equal to 140 ml during cardiac catheterization.

Prognostic Value of Neutrophil to Lymphocyte Ratio and Risk Factors for Mortality in Patients with Stanford Type A Aortic Dissection.

BACKGROUND: Neutrophil to lymphocyte ratio (NLR) is a prognostic predictor in a wide range of cardiovascular disease. Acute aortic dissection (AD) is an uncommon but fatal cardiovascular disease. In this study, we investigated both prognostic factors in patients with AD and whether NLR can be a predictor for mortality. Methods: We analyzed retrospectively the data of 57 patients with AD who had undergone emergent surgery in our hospital and included 128 consecutive patients with chest pain admitted to the emergency room as a control group. Also, patients who were operated on due to aortic dissection as another subgroup were compared to NLR values. Baseline clinical features, cardiovascular risk factors, and surgical and laboratory parameters were obtained from the hospital database. Results: Patients with AD had higher NLR than the control group (1.7 ± 0.5 versus 7.6 ± 3.3, P < .001). In the AD group, 15 deaths occurred and non-survivors had significantly higher NLR, compared to survivors (11.6 ± 2.4 versus 6.6 ± 2.3, P < .001). In multivariate analysis, high NLR (odds ratio [OR] 1.913, 95% CI 1.030-1.081, P = .04) and cross-clamp time (OR 1.265, 95% CI 1.003-1.596, P = .04) were determined as independent predictors of in-hospital mortality. In receiver operating characteristics curve analyses, the NLR > 9.3 predicted the mortality in AD with a specificity of 91% and a sensitivity of 86% (P < .001). CONCLUSION: This study shows that high NLR can be used as a marker for prognosis in short-term mortality of patient with AD. Additionally, increased lactate level in perioperative period, prolonged cardiopulmonary bypass time, and additional cardiac procedures are strong independent predictors of short-term mortality in patients with acute AD.
