Background: Coronary artery fistula (CAF) is an abnormal connection that links a coronary artery to a cardiac chamber or another major blood vessel. Several studies have shown the association between mean platelet volume (MPV) and cardiovascular diseases. In the literature, there is no previous study about the association between hematologic parameters and congenital CAF. For this reason, we aimed to investigate the association of MPV with CAF. Methods: 70 patients with normal coronary arteries and 50 with coronary artery fistulas […]

Background: Sirtuins may act in many cellular processes like apoptosis, DNA repair and lipid/glucose metabolism. Experimental studies suggested some sirtuin types may have protective effects against endothelial dysfunction, atherosclerosis, cardiac hypertrophy and reperfusion injury. Data about sirtuins in acute myocardial infarction (AMI) patients are scarce. Objectives: To investigate temporal changes of serum sirtuin 1,3 and 6 levels in AMI patients; to compare the serum sirtuin 1,3 and 6 levels between AMI patients and control subjects; and to investigate the association […]

Abstract Background: Observational studies have highlighted an association between serum uric acid (SUA) levels and cardiovascular risk factors. Despite the growing body of evidences, several studies were conducted in older individuals or in carriers of diseases susceptible to affect SUA levels and cardiometabolic risk markers. Objective: To evaluate the relationship of SUA with body adiposity, metabolic profile, oxidative stress, inflammatory biomarkers, blood pressure and endothelial function in healthy young and middle-aged adults. Methods: 149 Brazilian adults aged 20-55 years, both […]

Based on the assumption that a classification system is a very critical subject and may significantly improve the prediction of individual responses to treatment and related diseases, we proposed 16 years ago a classification for endothelial dysfunction including etiological, functional, and evolutionary aspects ().
