ABSTRACT
Resumo Fundamento: As diretrizes da Sociedade Europeia de Cardiologia recomendam um nível de colesterol LDL (LDL-C) < 55 mg/dL para pacientes com doença cardiovascular estabelecida. Embora a fórmula de Friedewald ainda seja amplamente utilizada para estimar o LDL-C, a fórmula mais recente de Martin-Hopkins mostrou maior precisão. Objetivos: Nosso objetivo foi avaliar: A) a proporção de pacientes que atingiram a meta de LDL-C e as terapias utilizadas em um centro terciário; B) o impacto da utilização do método de Martin-Hopkins em vez do método de Friedewald na proporção de pacientes controlados. Métodos: Estudo transversal monocêntrico, incluindo pacientes consecutivos pós-infarto do miocárdio, acompanhados por 20 cardiologistas, em um hospital terciário. Os dados foram coletados retrospectivamente de consultas clínicas realizadas após abril de 2022. Para cada paciente, os níveis de LDL-C e o atingimento das metas foram estimados a partir de um perfil lipídico ambulatorial, utilizando as fórmulas de Friedewald e Martin-Hopkins. Um valor-p bicaudal < 0,05 foi considerado estatisticamente significativo para todos os testes. Resultados: Foram incluídos 400 pacientes (com 67 ± 13 anos, 77% do sexo masculino). Utilizando a fórmula de Friedewald, a mediana de LDL-C sob terapia foi de 64 (50-81) mg/dL, e 31% tinham LDL-C dentro da meta. Estatinas de alta intensidade foram usadas em 64% dos pacientes, 37% estavam em uso de ezetimiba e 0,5% estavam em uso de inibidores de PCSK9. A terapia combinada de estatina de alta intensidade + ezetimiba foi utilizada em 102 pacientes (26%). A aplicação do método de Martin-Hopkins reclassificaria um total de 31 pacientes (7,8%). Entre aqueles considerados controlados pela fórmula de Friedewald, 27 (21,6%) teriam LDL-C estimado por Martin-Hopkins acima da meta. Conclusões: Menos de um terço dos pacientes pós-infarto do miocárdio apresentaram LDL-C dentro da meta. A aplicação da fórmula de Martin-Hopkins reclassificaria um quinto dos pacientes presumivelmente controlados no grupo de pacientes não controlados.
Abstract Background: The European Society of Cardiology guidelines recommend an LDL-cholesterol (LDL-C) < 55 mg/dL for patients with established cardiovascular disease. While the Friedewald equation to estimate LDL-C is still widely used, the newer Martin-Hopkins equation has shown greater accuracy. Objectives: We aimed to assess: A) the proportion of patients reaching LDL-C goal and the therapies used in a tertiary center; B) the impact of using the Martin-Hopkins method instead of Friedewald's on the proportion of controlled patients. Methods: A single-center cross-sectional study including consecutive post-myocardial infarction patients followed by 20 cardiologists in a tertiary hospital. Data was collected retrospectively from clinical appointments that took place after April 2022. For each patient, the LDL-C levels and attainment of goals were estimated from an ambulatory lipid profile using both Friedewald and Martin-Hopkins equations. A two-tailed p-value of < 0.05 was considered statistically significant for all tests. Results: Overall, 400 patients were included (aged 67 ± 13 years, 77% male). Using Friedewald's equation, the median LDL-C under therapy was 64 (50-81) mg/dL, and 31% had LDL-C within goals. High-intensity statins were used in 64% of patients, 37% were on ezetimibe, and 0.5% were under PCSK9 inhibitors. Combination therapy of high-intensity statin + ezetimibe was used in 102 patients (26%). Applying the Martin-Hopkins method would reclassify a total of 31 patients (7.8%). Among those deemed controlled by Friedewald's equation, 27 (21.6%) would have a Martin-Hopkins' LDL-C above goals. Conclusions: Less than one-third of post-myocardial infarction patients had LDL-C within the goal. Applying the Martin-Hopkins equation would reclassify one-fifth of presumably controlled patients into the non-controlled group.
ABSTRACT
ABSTRACT Objective: We aimed to analyze the association of diabetes and subclinical hypothyroidism with subclinical atherosclerosis measured by coronary artery calcium (CAC) in the baseline of the ELSA-Brasil study. Materials and methods: CAC was measured using a 64-detector computed tomographic scanner. The association of CAC > 0 was presented as an odds ratio (OR) and 95% confidence intervals (95%CI) in logistic models and as β (95%CI) in linear models after multivariable adjustment for confounders. Results: We analyzed 3,809 participants (mean-age (SD) 50.5 (8.8); 51.7% women). In the main analysis, we did not find an association of diabetes and subclinical hypothyroidism with CAC. However, in stratified analysis according to age strata, we found no significative interaction terms, an important heterogeneity between the groups, with the younger age strata showing an association of the group with both diseases and CAC > 0 (OR 7.16; 95%CI, 1.14; 44.89) with a wide but significative 95%CI, suggesting that the smaller number of participants in the younger group may influence the results. Our findings also showed an association of CAC > 0 and log (CAC+1) with diabetes in logistic (OR, 1.31; 95%CI, 1.05-1.63) and linear models (β, 0.24, 0.16, 0.40), respectively. Diabetes was independently associated with CAC > 0 in linear models. Discussion: In conclusion, our results showed a great heterogeneity in stratified analysis based on age in the younger age strata. Although we found no significant interaction factors, the smaller sample size for the analysis may influence the negative findings.
ABSTRACT
Abstract Background: People with haemophilia (PwH) are living longer. Therefore, they can develop atherosclerotic cardiovascular disease (ASCVD). Electrocardiogram (ECG) alterations may be a sign of initial ASCVD before the occurrence of symptoms. Objective: To describe the prevalence of resting ECG alterations among PwH adults asymptomatic for ASCVD. Methods: PwH aged ≥ 30 years without previous ASCVD events were considered for the analysis. Resting ECG traces were analysed according to international reference values and the Brazilian Longitudinal Adult Health Study (ELSA-Brasil) results for asymptomatic Brazilian men. Based on the established normal values and using the QT index, we further described the altered ECGs as minor or major changes, according to the Minnesota Code. Differences between prevalences were evaluated by Pearson's χ2 test. Differences between medians were evaluated by the Mann-Whitney U test. A p-value < 0.05 was accepted as statistically significant. Results: A total of 64 PwH were included in the study. Median age was 44 years (interquartile range 35-52). Most patients had haemophilia A (81%) and 47% were severe. The prevalence of obesity, systemic arterial hypertension (SAH), diabetes mellitus (DM), and dyslipidaemia were 16%, 56%, 14%, and 72%, respectively. All the PwH had sinus rhythm, except for one, who had an implanted pacemaker due to idiopathic third-degree atrioventricular block. Altered ECGs were found in 25% and 30% of PwH, according to established criteria and ELSA-Brasil criteria, respectively. Major changes were found in eight (13%) PwH according to the Minnesota Code, including two ECGs with ischaemia-like wall inactivity. Conclusions: The prevalence of altered ECG varied from 25% to 30% among asymptomatic PwH.
ABSTRACT
Atherosclerosis （AS） is a chronic inflammatory pathological process in which lipid and/or fibrous substances are deposited in the intima of arteries， and it is one of the pathological bases of many cardiovascular and cerebrovascular diseases. Endoplasmic reticulum stress （ERS） is a protective mechanism of cell adaptation. Moderate ERS can reduce abnormal protein aggregation and increase the degradation of misfolded proteins to repair and stabilize the internal environment， while excessive ERS can cause unfolded protein reaction， activate inflammation， oxidative stress， apoptosis， autophagy， and other downstream pathways， and lead to cell damage， or even apoptosis. A large number of studies have shown that ERS mediates a variety of pathological processes related to AS， affects endothelial cells， smooth muscle cells， macrophages， endothelial progenitor cells， and other cell components closely related to its occurrence and development， influences the progress of AS by regulating cell function， and promotes the formation of AS plaque， the transformation of stable plaque to unstable plaque， and the rupture of unstable plaque. Regulation of ERS may be a key target for the prevention and treatment of AS， and it is a research hotspot at present. Traditional Chinese medicine （TCM） believes that the origin of AS is the imbalance of Yin and Yang， the disharmony of Zangfu organs， and the abnormal operation of Qi， blood， and body fluid， which leads to the accumulation of phlegm， blood stasis， and other pathological products in the pulse channels， making the blood flow blocked or misfunction and causing the disease， which belongs to the syndrome of deficiency in origin and excess in superficiality. As the pathogenesis of AS is complex， and the symptoms are diverse， TCM has significant advantages in treating AS because of its multiple targets， multiple pathways， stable efficacy， strong individualization， and high safety. This paper systematically elaborated on the role of ERS in the occurrence and development of AS and summarized the mechanism research on the regulation and control of ERS by Chinese herbal monomer， Chinese herbal extract， Chinese herbal compound， and proprietary medicine， so as to provide a theoretical basis for clinical research and drug development in the prevention and treatment of AS.
ABSTRACT
Objective To investigate the infection of Chlamydia pneumoniae and mycoplasma pneumoniae in adults and their association with atherosclerosis,and to provide theoretical guidance for the prevention of such diseases. Methods A case-control study was used to collect 362 patients who were diagnosed with atherosclerosis from January 2019 to December 2021 in Department of Sichuan Bazhong Central Hospital, and 370 cases who were admitted to the hospital during the same period of physical examination without any cardiovascular disease were selected as the control group, and whole blood samples of the two groups of study subjects were collected, and the infection of Chlamydia pneumoniae and mycoplasma pneumoniae was detected by PCR. Results The infection rate of Chlamydia pneumoniae was 35.49%, the infection rate of mycoplasma was 40.37%, and the co-infection rate was 11.37%；The infection rate of Chlamydia pneumoniae in the control group was 12.04%, the infection rate of mycoplasma was 15.83%, and the coinfection rate was 3.14%, and the difference between the two groups was statistically significant ( χ2=10.926, P=0.023). The effects of mycoplasma, chlamydia, and co-infection on atherosclerotic patients have sex differences, mainly manifested as higher infection rates in men; In addition, the effects of mycoplasma, chlamydia, and co-infection on atherosclerosis patients varied by age, mainly in the 55-70 years age group (P<0.05). Multivariate logistic regression results showed that Chlamydia pneumoniae infection was a risk factor for atherosclerosis (OR=1.303, 95%CI: 1.043-1.677) in the whole population, and chlamydia pneumoniae (OR=1.472, 95% CI: 1.037-1.556), mycoplasma (OR=2.003, 95%CI: 1.637-3.842) and co-infection in men (OR=1.937, 95%CI: 1.380-2.184) were risk factors for atherosclerosis, while co-infection in women (OR=1.699, 95%CI: 1.263-1.765) was a risk factor for atherosclerosis. Conclusion Chlamydia pneumoniae and mycoplasma infection are risk factors for atherosclerosis, and their impact on male groups is greater, and more attention needs to be paid to them.
ABSTRACT
Overweight/obesity has become an increasingly serious global public health problem. Studies have shown that many factors caused by overweight/obesity are involved in the occurrence of atherosclerosis, including adipokines, inflammatory factors and overweight/obesity related metabolic syndrome. This paper reviews the research progress on overweight/obesity and atherosclerosis from the above perspectives, aiming to provide reference for the prevention of overweight/obesity-related atherosclerosis.
ABSTRACT
Resumen El endotelio es una monocapa formada por células aplanadas llamadas w, que revisten la parte más interna del corazón, los vasos sanguíneos y los linfáticos. Es considerado un órgano que tiene una función de barrera, pero además se encarga de regular la permeabilidad y tono vascular, hemostasia, inflamación y angiogénesis. Esta revisión se centra sobre todo en las generalidades del endotelio vascular sano y su disfunción. Se analizan los conceptos de activación y disfunción, en donde la activación se considera como un proceso autolimitado, indispensable para la hemostasia y la inflamación. La disfunción endotelial, en cambio, es un proceso patológico, de mayor duración y que se presenta cuando el endotelio ya no puede autorregularse y cambia a un fenotipo proinflamatorio y protrombótico permanente. Esta disfunción es el primer cambio que lleva a la ateroesclerosis y al aumento del riesgo cardiovascular, por esta razón se revisan los principales biomarcadores de disfunción endotelial y riesgo cardiovascular. A medida que se avance en el conocimiento básico del endotelio y su disfunción, será posible diseñar nuevas medidas preventivas o terapéuticas que puedan disminuir dicho riesgo.
Abstract The endothelium is a monolayer of flatten cells named endothelial cells that form the inner layer of the heart, blood, and lymphatic vessels. Its function is not just as a barrier, but it is a regulator of vascular permeability and tone, hemostasis, inflammation, and angiogenesis. This review is about the general aspects of vascular endothelium and endothelial dysfunction that leads to increased vascular risk. Activation and dysfunction are discussed, considering the endothelial activation as a self-limiting process, necessary to promote inflammation and hemostasis. Endothelial dysfunction is a pathological process in which the endothelium loses its ability for self-regulation and acquires a prothrombotic and proinflammation phenotype. Endothelial dysfunction is the initial step for atherosclerosis and increased cardiovascular risk, so the main biomarkers of endothelial dysfunction are reviewed. As basic knowledge about endothelium increases, preventive or therapeutic measures can be designed as treatment or prevention the risk of its dysfunction.
ABSTRACT
Introducción: La Enfermedad Arterial Periférica (EAP) es definida como la oclusión de las arterias de las extremidades, se reconoce como la tercera causa de morbilidad vascular aterosclerótica, después del infarto agudo de miocardio y el accidente cerebrovascular. Aunque las enfermedades cardiovasculares se han relacionado con la ocupación, la información sobre la relación entre el trabajo con la EAP es escasa. Objetivo: Identificar la prevalencia de EAP en población laboralmente activa y su relación con variables sociodemográficas, clínicas y estilo de vida. Metodología: Se realizó un estudio analítico de tipo transversal, en 203 sujetos de 40 años o más, laboralmente activos de Popayán. Tras la firma del consentimiento, se realizó una entrevista, y se registraron las variables sociodemográficas y clínicas. Para el tamizaje de EAP se evaluó el índice tobillo brazo (ITB). Los participantes se clasificaron en categorías basadas en el ITB de la siguiente manera: EAP ≤ 0,90; 0,91 a 0,99 normal; y no compresible > 1,40. Los datos fueron analizados con el programa SPSS versión 26.0, se aplicó la prueba de Kolmogorov-Smirnov como prueba de normalidad, la t Student para evaluar diferencias de medias entre los grupos de estudio y la prueba de Chi-cuadrado. Resultados y discusión: La prevalencia fue del 2,5 % para EAP, siendo el primer estudio reportado para población trabajadora en Colombia. La EAP fue más prevalente en empleados manuales (2,8 %) e ingresos bajos (30 %); además, fueron obesos y fumadores. El riesgo encontrado para edad fue OR 1,5; IC95 % 1,17 a 2,14, género OR 1,2; IC95 % 1,20 a 3,28 y DM2 OR 1,5; IC95 % 1,23 a 6,68. Conclusión: Se estableció por primera vez la prevalencia de EAP (2,5 %) en una población laboralmente activa de Popayán, siendo más prevalente en los individuos con ingresos bajos, expuestos a factores de riesgo cardiovascular y con antecedente familiar de DM2.
Introduction: The Peripheral Arterial Disease (PAD) is defined as the occlusion of the extremities' arteries, and it is known to be the third vascular atherosclerotic cause of death after acute myocardial infarction and brain stroke. Even though cardiovascular diseases had been linked to occupation, information about the relation between PAD and labor activity runs short. Objective: To identify the PAD prevalence in the working population and its relationship with sociodemographic, clinical and lifestyle variables. Methodology: A cross-sectional analytical study was conducted in 203 people of >40 years, actively working in the city of Popayán. After consent signing, interviews were completed to record such variables. PAD testing was evaluated through Ankle-Brachial Index (ABI). Participants were grouped into categories based on ABI as follows: PAD ≤0.90; normal 0.91 to 0.99; and non-compressible >1.40. Collected data was analyzed in SPSS version 26.0, applying Kolmogorov-Smirnov test as the normal; t Student test to evaluate mean differences between study groups and Chi-square. Results and discussion: PAD prevalence was 2.5 % being the very first report done for Colombia's working class. PAD was prevalent for manual-labor employees (2.8 %), low-income people (30 %), adding obesity and smoking to their profile. Age risk found was (OR 1.5; IC 95 % 1.17 to 2.14), by gender (OR 1.2; IC 95 % 1.20 to 3.28); DM2 (OR 1.5; IC 95 % 1.23 to 6.68). Conclusion: It was determined for the first time a prevalence of (2.5 °%) PAD for a population actively working in Popayán, being more frequent with individuals with low income, people exposed to higher cardiovascular risks, and for people with family DM2 records.
ABSTRACT
Resumo Fundamento A busca por métodos clinicamente úteis de avaliação de doenças ateroscleróticas, com boa acurácia, de baixo custo, sem invasividade e de fácil manejo, há anos vem sendo estimulada. Dessa forma, os índices aterogênicos avaliados deste estudo podem se encaixar nesta demanda crescente. Objetivos Avaliar o potencial dos índices aterogênicos como métodos de avaliação de pacientes portadores de aterosclerose clínica. Métodos Estudo transversal de centro único, por meio do qual foram avaliados os índices de Castelli I e II, índice aterogênico plasmático (IAP), índice de combinação de lipoproteínas e a variação do índice de perfusão periférica entre 90 e 120 segundos após um estímulo vasodilatador endotélio-dependente (ΔIPP90-120) na predição de aterosclerose. A significância estatística foi estabelecida em p < 0,05. Resultados A amostra foi composta por 298 indivíduos com idade média de 63,0 ± 16,1 anos, dos quais 57,4% eram mulheres. Comparações pareadas da análise curva ROC dos índices que alcançaram área sob a curva (ASC) > 0,6 mostram que ΔIPP90-120 e IAP foram superiores aos demais índices, sem diferenças observadas entre si (diferença entre ASC = 0,056; IC95% -0,003-0,115). Ademais, tanto a ΔIPP90-120 [odds ratio (OR) 9,58; IC95% 4,71-19,46] quanto o IAP (OR 5,35; IC95% 2,30-12,45) foram preditores independentes de aterosclerose clínica. Conclusões O IAP e ΔIPP90-120 apresentaram melhor acurácia para discriminar aterosclerose clínica. Além disso, foram preditores independentes de aterosclerose clínica, evidenciando uma possibilidade promissora para o desenvolvimento de estratégias preventivas e de controle para doenças cardiovasculares. Tratam-se, portanto, de marcadores adequados para estudos multicêntricos do ponto de vista de praticidade, custo e validade externa.
Abstract Background The search for clinically useful methods to assess atherosclerotic diseases (ASCVD) with good accuracy, low cost, non-invasiveness, and easy handling has been stimulated for years. Thus, the atherogenic indices evaluated in this study may fit this growing demand. Objectives To assess the potential of atherogenic indices to evaluate patients with clinical atherosclerosis. Methods Single-center cross-sectional study, through which the Castelli I and II indices, the atherogenic index of plasma (AIP), the lipoprotein combine index, and the variation in the peripheral perfusion index between 90 and 120 seconds after an endothelium-dependent (ΔPI90-120) vasodilator stimulus were evaluated in the prediction of atherosclerosis. Statistical significance was set at p < 0.05. Results The sample consisted of 298 individuals with an average age of 63.0±16.1 years, of which 57.4% were women. Paired comparisons of the ROC curve analysis of the indices that reached the area under the curve (AUC) > 0.6 show that ΔPI90-120 and AIP were superior to other indices, and no differences were observed between them (difference between AUC = 0.056; 95%CI -0.003-0.115). Furthermore, both the ΔPI90-120 [odds ratio (OR) 9.58; 95%CI 4.71-19.46)] and AIP (OR 5.35; 95%CI 2.30-12.45) were independent predictors of clinical atherosclerosis. Conclusions The AIP and ΔPI90-120 represented better accuracy in discriminating clinical ASCVD. Moreover, they were independent predictors of clinical ASCVD, evidencing a promising possibility for developing preventive and control strategies for cardiovascular diseases. Therefore, they are markers for multicenter studies from the point of view of practicality, low cost, and external validity.

Abstract Cardiovascular diseases are among important causes of death. Atherosclerosis is an important etiology for coronary artery diseases in which coronary artery calcification plays a principal role. Recently novel cardiovascular risk factors in coronary calcification are under attention. In this study, we investigated possible association between novel cardiovascular risk factors and coronary calcification. This is a prospectively registered systematic review and meta-analysis in PROSPERO and was performed in accordance with PRISMA guidelines. Medical databases were searched. Primary papers were screened and studies reporting our outcomes of interest were selected for data extraction. Quantitative data syntheses were performed using Comprehensive Meta-analysis Ver.3. In this study, 5252 papers were screened and finally 28 papers including 31241 patients underwent data extraction. Based on our findings, neutrophil/lymphocyte ratio (8 out of 10), red cell distribution width (r = 0.250, p < 0.0001), and interleukin 6 (odds ratio [OR]: 1.101 [95% confidence interval (CI): 1.001-1.210], p = 0.047) were associated with severity of coronary calcification while C-reactive protein (one out of eight) was not associated with coronary calcification. Results of lymphocyte/monocyte ratio (r = -0.120, p < 0.001), platelet/lymphocyte ratio (OR: 1.47 [95% CI: 0.89-2.41, p = 0.124]), and MPV (r = 0.017, p = 0.814 vs. OR: 1.91 [95% CI: 1.28-2.85, p = 0.002]) remained controversial due to few number of included studies or contrary results. We can conclude that neutrophil/lymphocyte ratio, red cell distribution width, and interleukin-6 are significantly associated with coronary calcification and C-reactive protein is not significantly associated with severity of coronary calcification. Our results about mean platelet volume, platelet/lymphocyte ratio, and lymphocyte/monocyte ratio are not reliable and require further investigations.
Resumen Las enfermedades cardiovasculares se encuentran entre las primeras causas de mortalidad. La aterosclerosis es una etiología importante de las enfermedades de las arterias coronarias en la que la calcificación de las arterias coronarias juega un papel principal. Recientemente, se están prestando atención a factores novedosos de riesgo cardiovascular en la calcificación coronaria. En este estudio investigamos la asociación posible entre los factores novedosos de riesgo cardiovascular y la calcificación coronaria. Esta es una revisión sistemática y metaanálisis registrados de forma prospectiva en PROSPERO y se realizó de acuerdo con las pautas de PRISMA. Se realizaron búsquedas en bases de datos médicas. Se examinaron los artículos primarios y se seleccionaron para la extracción de datos los estudios cuyos resultados fueron de nuestro interés. Las síntesis de datos cuantitativos se realizaron utilizando Comprehensive Meta-analysis Ver.3. En este estudio se seleccionaron 5252 artículos y finalmente se extrajeron los datos de 28 artículos que incluían 31241 pacientes. Según nuestros hallazgos, la proporción de neutrófilos/linfocitos (8 de 10), el ancho de distribución de glóbulos rojos (r = 0,250, valor de p < 0.0001) y la interleucina 6 (OR: 1.101 [IC del 95%: 1.001-1.210], valor p = 0.047) se asociaron con la gravedad de la calcificación coronaria, mientras que la proteína C reactiva (1 de 8) no se asoció con la calcificación coronaria. Resultados de la proporción linfocitos/monocitos (r = -0,120, valor p < 0,001), la proporción plaquetas/linfocitos (OR: 1,47 [IC 95%: 0.89-2.41, valor p = 0.124]) y el volumen plaquetario medio (r = 0.017, valor p = 0.814 C. OR: 1.91 [IC 95%: 1.28-2.85, valor p = 0.002]) siguieron siendo polémicos debido al escaso número de estudios incluidos o resultados contrarios. Podemos concluir que la proporción de neutrófilos/linfocitos, el ancho de distribución de los glóbulos rojos y la interleucina 6 se asocian significativamente con la calcificación coronaria y la proteína C reactiva no se asocia significativamente con la gravedad de la calcificación coronaria. Nuestros resultados sobre el volumen plaquetario medio, la proporción de plaquetas/linfocitos y la proporción de linfocitos/monocitos no son confiables y requieren más investigaciones.
ABSTRACT
Background: An elevated cardiovascular risk has been demonstrated in middle-aged individuals with onset of hair greying before the age of 30 years. Increased serum levels of pro-inflammatory cytokines, interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-?), indicate an ongoing state of chronic inflammation that is correlated with cardiovascular risk but have not been studied earlier in patients with early onset of hair greying. Aim/Objective: To study various cardiovascular risk markers including pro-inflammatory cytokines interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-?) in patients with premature canities. Methods: This was a hospital-based case-control study of 40 patients with premature canities (age between 19 and 25 years; >5 grey hair) and an equal number of age and gender-matched healthy controls. The blood pressure, pulse rate and body mass index were recorded, and investigations including fasting blood sugar, serum insulin, fasting lipid profile, high sensitivity c-reactive protein (hs-CRP), IL-6 and TNF-? were performed. The homeostatic model assessment of insulin resistance (HOMA-IR) was calculated for all the participants. Results: The mean blood pressure, fasting blood sugar, serum insulin, hs-CRP and HOMA-IR were all significantly elevated in patients with premature canities and the serum HDL levels were significantly lower. A greater number of patients with premature canities had significantly elevated IL-6 as compared with the controls. Limitations: The sample size was small. A subjective scale was used for grading the severity of premature canities. Trichoscopic evaluation of severity of greying or modified phototrichogram could not be used in this study. Conclusion: Abnormalities in cardiovascular risk markers were found in patients with premature canities. Screening and counselling of patients with premature greying of hair is recommended in order to prevent future cardiovascular disease.

AtherosclerosisABSTRACT
ABSTRACT In individuals with very low high-density lipoprotein (HDL-C) cholesterol, such as Tangier disease, LCAT deficiency, and familial hypoalphalipoproteinemia, there is an increased risk of premature atherosclerosis. However, analyzes based on comparisons of populations with small variations in HDL-C mediated by polygenic alterations do not confirm these findings, suggesting that there is an indirect association or heterogeneity in the pathophysiological mechanisms related to the reduction of HDL-C. Trials that evaluated some of the HDL functions demonstrate a more robust degree of association between the HDL system and atherosclerotic risk, but as they were not designed to modify lipoprotein functionality, there is insufficient data to establish a causal relationship. We currently have randomized clinical trials of therapies that increase HDL-C concentration by various mechanisms, and this HDL-C elevation has not independently demonstrated a reduction in the risk of cardiovascular events. Therefore, this evidence shows that (a) measuring HDL-C as a way of estimating HDL-related atheroprotective system function is insufficient and (b) we still do not know how to increase cardiovascular protection with therapies aimed at modifying HDL metabolism. This leads us to a greater effort to understand the mechanisms of molecular action and cellular interaction of HDL, completely abandoning the traditional view focused on the plasma concentration of HDL-C. In this review, we will detail this new understanding and the new horizon for using the HDL system to mitigate residual atherosclerotic risk.
ABSTRACT
Aims : To calculate the prevalence of Dyslipidemia in patients with Mycobacterium Tuberculosis infection (Mtb) and Diabetes Mellitus (DM). Materials and Methods : A study done on 294 patients infected with Mtb were enrolled in the study. Patients infected with Tuberculosis (TB) were selected from Medicine and Pulmonary Medicine Departments in MLN Medical College Prayagraj. Patients were segregated into two groups on the basis of glucose tolerance; Abnormal Glucose Tolerance (AGT) and Normal Glucose Tolerance (NGT). Results: A total of 294 patients with TB were taken in the study, 143 patients in AGT group and 151 patients in NGT group. The average age of the patients in AGT group was 47.91 years. Among AGT and NGT, Dyslipidemia was found to be statistically significant among AGT group (p=0.01). Mean Serum Triglycerides (209.8, p<0.004) and LDL Cholesterol (144.3, p<0.0001) in AGT group. Conclusion : Patient with TB DM are more prone for Dyslipidemia and atherogenicity
ABSTRACT
Introducción: La enfermedad periodontal ha sido identificada como un factor de riesgo para enfermedades del corazón. La falta de hábitos de higiene bucal asociados a factores de riesgo puede conducir al desarrollo de periodontitis, lo que conducirá a un aumento de mediadores inflamatorios en la sangre, lo que es un riesgo potencial para el desarrollo del proceso de aterosclerosis. Objetivo: Evaluar en la literatura la influencia de la enfermedad periodontal en las enfermedades cardiovasculares, especialmente en relación con la aterosclerosis. Método: Consistió en una búsqueda en libros y artículos científicos, con la utilización de palabras clave asociadas, así como artículos seleccionados en las bases de datos SciELO, PubMed, Scopus, de lo cual se obtuvieron alrededor de 40 bibliografías, que fueron decantadas a 35, de ellas el 50 % actualizadas. Resultados: estudios de metaanálisis apoyan una relación causal entre la enfermedad periodontal y la cardiopatía, lo que demuestra que el riesgo de desarrollar algunas complicaciones vasculares se encontró aumentado en pacientes con problemas periodontales. Conclusiones: Se hace relevante evaluar la relación de estas enfermedades y los mecanismos implicados, para poder elaborar medidas preventivas.
Introduction: Periodontal disease has been identified as a risk factor for heart disease. The lack of oral hygiene habits associated with risk factors can lead to the development of periodontitis, which will lead to an increase in inflammatory mediators in the blood, which is a potential risk for the development of the atherosclerosis process. Objective: To evaluate in the literature the influence of periodontal disease on cardiovascular diseases, especially in relation to atherosclerosis. Method: It consisted of a search in books and scientific articles, with the use of associated keywords, as well as selected articles in the SciELO, PubMed, Scopus databases, from which around 40 bibliographies were obtained, which were narrowed down to 35, of them 50% updated. Results: Meta-analysis studies support a causal relationship between periodontal disease and heart disease, demonstrating that the risk of developing some vascular complications was found to be increased in patients with periodontal problems. Final considerations: It is relevant to evaluate the relationship between these diseases and the mechanisms involved, in order to develop preventive measures.

ABSTRACT
Abstract Background Psoriasis is a protean disease associated with several comorbidities that may have increased levels of adiponectin such as resistin. This may affect the patients atherosclerotic risk. Objective To study resistin levels in a sample of Brazilian patients with psoriasis and its association with clinical profile, comorbidities, and carotid Intima-Media Thickness (cIMT). Methods This is a cross-sectional study of 119 individuals: 34 healthy controls and 85 patients with psoriasis, 42 of which with skin involvement only and 43 with psoriatic arthritis. Clinical and epidemiological data, measurement of PASI (Psoriasis Area Severity Index) and DAPSA (Disease Activity in Psoriatic Arthritis), lipid profile, cIMT by ultrasound were collected from medical records. Resistin serum levels were measured by ELISA. Results Patients with psoriasis had higher resistin levels (p = 0.009) and worse cIMT (p = 0.0002) than controls. In the psoriasis sample, no associations of resistin levels with epidemiological, clinical findings, and activity indexes were found. Resistin serum levels were associated with the presence of diabetes (p = 0.008) and metabolic syndrome (p = 0.01) and correlated with total cholesterol (r = 0.26) and triglycerides (r = 0.33) but not with cIMT. Study limitations This work is limited by its transversal design and by the limited number of patients included. Conclusion Resistin serum levels are elevated in psoriasis patients. In this sample, clinical, epidemiological, and activity indexes were not linked to resistin serum levels, but atherosclerotic risk factors were.
ABSTRACT
Resumo Fundamento Identificar os indivíduos assintomáticos sob risco de desenvolver doenças cardiovasculares é um dos principais objetivos da cardiologia preventiva. O escore de cálcio coronariano (ECC) permite estimar a idade vascular, que se mostrou mais fidedigna que a idade cronológica na determinação do risco cardiovascular. Objetivos Reclassificar o risco cardiovascular com base na idade arterial e avaliar a progressão do escore de cálcio durante o seguimento. Métodos 150 homens assintomáticos foram submetidos a avaliação clínica e do ECC em 2 avaliações com intervalo de 7,6 anos. Classificamos os pacientes pelos escores de risco tradicionais e pela idade arterial. Avaliamos quais variáveis se associaram a maior progressão do ECC durante o período. O nível de significância estatística considerado foi de 5% (p < 0,05). Resultados A utilização da idade arterial na estratificação do risco cardiovascular em comparação ao escore de risco de Framingham (ERF) reclassificou 29% dos indivíduos para uma categoria de risco superior e 37% para uma categoria inferior. Em relação ao escore da AHA e ACC (ASCVD), 31% passaram para um risco maior e 36% para um risco menor. A classificação inicial pela idade arterial teve relação direta com a progressão do ECC ao longo do seguimento (p < 0,001), fato que não foi observado para o ERF (p = 0,862) e ASCVD (p = 0,153). As variáveis individuais que mais se associaram à progressão do ECC foram a pressão arterial sistólica e o HDL baixo. Conclusão A estratificação de risco cardiovascular utilizando a idade arterial apresentou melhor associação que o ERF e ASCVD na identificação de indivíduos com maior risco de progressão da aterosclerose.
Abstract Background Identifying asymptomatic individuals at risk of developing cardiovascular disease is one of the main goals of preventive cardiology. The coronary calcium score (CCS) makes it possible to estimate vascular age, which has shown to be more reliable than chronological age for determining cardiovascular risk. Objectives To reclassify cardiovascular risk based on arterial age and evaluate CCS progression during follow-up. Methods We included 150 asymptomatic men who underwent clinical and CCS evaluation in 2 evaluations with an interval of 7.6 years. We classified patients by traditional risk scores and arterial age. We evaluated which variables were associated with greater CCS progression during the period, considering a statistical significance level of 5% (p < 0.05). Results The use of arterial age in the stratification of cardiovascular risk in comparison with the Framingham risk score (FRS) reclassified 29% of individuals to a higher risk category and 37% to a lower risk category. Regarding the American Heart Association and American College of Cardiology score (ASCVD), 31% were reclassified as higher risk and 36% as lower risk. The initial classification by arterial age was directly related to the progression of CCS throughout follow-up (p < 0.001). This was not observed for the FRS (p = 0.862) or ASCVD (p = 0.153). The individual variables most associated with CCS progression were high systolic blood pressure and low HDL. Conclusion Cardiovascular risk stratification using arterial age showed a better association than the FRS and ASCVD in identifying individuals with higher risk of atherosclerosis progression.
