Abstract Background The angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism (rs4340) is associated with the pathogenesis of heart failure (HF). This polymorphism may contribute to a greater propensity for severe HF and excess weight. Objective To evaluate adiposity, cardiac function, and their association with ACE I/D polymorphism in HF patients. Methods Cross-sectional study with ambulatory individuals ≥18 years diagnosed with HF. Genetic analysis was performed using polymerase chain reaction followed by agarose gel electrophoresis. Left ventricular ejection fraction (LVEF) was determined […]

Dear Editor, We would like to share ideas on the publication “Association of Paraoxonase-1 Genotype and Phenotype with Angiogram Positive Coronary Artery Disease”. Soflaei et al. noted that The presence of the G allele of the rs662 single nucleotide polymorphism is independently associated with an increased risk of coronary artery disease (CAD). The effect of polymorphism is investigated in this study. CAD might or might not be impacted by the hereditary component studied in this report. We both concur that […]

Background: Periodontitis and coronary artery disease (CAD) share an inflammatory etiology; there is a recent concern regarding the investigation of an association between these two conditions. Current theories indicate that cytokines and proteins have an important role in this process. C-reactive protein and interleukin-6 are inflammatory derivatives produced in the presence of periodontitis and in the pathophysiology of coronary disease. The polymorphisms of CRP + 1444 C > T and IL6-174 G > C are recognized in the literature as […]

Abstract Background: Genetic risk score can quantify individual’s predisposition to coronary artery disease; however, its usefulness as an independent risk predictor remains inconclusive. Objective: To evaluate the incremental predictive value of a genetic risk score to traditional risk factors associated with coronary disease. Methods: Thirty-three genetic variants previously associated with coronary disease were analyzed in a case-control population with 2,888 individuals. A multiplicative genetic risk score was calculated and then divided into quartiles, with the 1st quartile as the reference […]

Abstract Background: Metabolic syndrome (MS) is a condition that, when associated with ischemic heart disease and cardiovascular events, can be influenced by genetic variants and determine more severe coronary atherosclerosis. Objectives: To examine the contribution of genetic polymorphisms to the extension and severity of coronary disease in subjects with MS and recent acute coronary syndrome (ACS). Methods: Patients (n = 116, 68% males) aged 56 (9) years, with criteria for MS, were prospectively enrolled to the study during the hospitalization […]

Abstract Background: Changes in the angiotensin-converting enzyme (ACE) gene may contribute to the increase in blood pressure and consequently to the onset of heart failure (HF). The role of polymorphism is very controversial, and its identification in patients with HF secondary to Chagas disease in the Brazilian population is required. Objective: To determine ACE polymorphism in patients with HF secondary to Chagas disease and patients with Chagas disease without systolic dysfunction, and to evaluate the relationship of the ACE polymorphism […]
