Physical exercise has been considered an important non-pharmacological therapy for the prevention and treatment of cardiovascular diseases. However, its effects on minor cardiac remodeling are not clear. To evaluate the influence of aerobic exercise on the functional capacity, cardiac structure, left ventricular (LV) function, and gene expression of NADPH oxidase subunits in rats with small-sized myocardial infarction (MI). Three months after MI induction, Wistar rats were divided into three groups Sham; sedentary MI (MI-SED); and aerobic exercised MI (MI-AE). The rats exercised on a treadmill three times a week for 12 weeks. An echocardiogram was performed before and after training. The infarction size was evaluated by histology, and gene expression was assessed by RT-PCR. https://www.selleckchem.com/products/loxo-292.html The significance level for statistical analysis was set at 5%. Rats with MI lower than 30% of the LV total area were included in the study. Functional capacity was higher in MI-AE than in Sham and MI-SED rats. The infarction size did not differ between groups. Infarcted rats had increased LV diastolic and systolic diameter, left atrial diameter, and LV mass, with systolic dysfunction. Relative wall thickness was lower in MI-SED than in the MI-AE and Sham groups. Gene expression of the NADPH oxidase subunits NOX2, NOX4, p22phox, and p47phox did not differ between groups. Small-sized MI changes cardiac structure and LV systolic function. Late aerobic exercise is able to improve functional capacity and cardiac remodeling by preserving the left ventricular geometry. NADPH oxidase subunits gene expression is not involved in cardiac remodeling or modulated by aerobic exercise in rats with small-sized MI. Small-sized MI changes cardiac structure and LV systolic function. Late aerobic exercise is able to improve functional capacity and cardiac remodeling by preserving the left ventricular geometry. NADPH oxidase subunits gene expression is not involved in cardiac remodeling or modulated by aerobic exercise in rats with small-sized MI. A major cause of death worldwide, cardiovascular diseases and their prevalence in cardiologists are little known. To describe life habits and cardiovascular risk factors (CVRF) and to investigate the prevalence of diagnosis, awareness, and control of these CVRF among cardiologists members affiliated to and specialists from the Brazilian Society of Cardiology. National multicenter cross-sectional study to assess Brazilian cardiologists using a questionnaire on life habits, preexisting diseases, current medications, anthropometric measurements, blood pressure, and levels of glucose and lipids. A total of 555 cardiologists were evaluated, of which 67.9% were male, with a mean age of 47.2±11.7 years. Most were non-smoker (88.7%) and physically active (77.1%), consumed alcohol (78.2%), had normal weight circumference (51.7%), and were overweight (56.1%). The prevalence of systemic arterial hypertension (SAH), diabetes mellitus (DM), and dyslipidemia (DLP) were 32.4%, 5.9%, and 49.7%, respectively, of which only 57.2%, 45.5%, and 49.6%, respectively, were aware of the diseases. The Brazilian cardiologists participating in the study had a high prevalence of SAH, DM and DLP, but only a half of participants were aware of these conditions and, among these, the rates of controlled disease were low for SAH and DLP, although cardiologists are professionals with great knowledge about these CVRF. These findings represent a warning sign for the approach of CVRF in Brazilian cardiologists and encourage the conduction of future studies.

Cardiovascular disease (CVD) mortality, after several decades of decrease, has shown a tendency towards the stabilization in some countries, including Brazil and Rio de Janeiro state. This new tendency was not further analyzed by gender, age group and region of the Rio de Janeiro state. To analyze the trends of premature and late mortality from CVD, ischemic heart disease (IHD) and cerebrovascular disease (CBVD) by gender in the city of Rio de Janeiro (capital) and the health regions of Rio de Janeiro state (from 1996 to 2016. Data on deaths and the population were obtained from DATASUS/MS. The rates were compensated by ill-defined codes, corrected by Ill-Defined Cardiovascular codes and gender and age-adjusted by the direct method (reference population - population of the state of Rio de Janeiro - 2000 census). The Joinpoint Trend Analysis Software was employed. IHD mortality stabilized or even increased for at least 50% of the analyzed areas (EAPC≥0). No change was observed. in the "North" and "Nortntion to women. It is suggested that serglycin has important functions in fibrin stabilization and inflammation but there is limited information on its clinical value for atherosclerotic heart disease. The purpose of this study is to find out serum serglycin levels in acute myocardial infarction patients and in the control group individuals; and to investigate the association between serglycin levels with inflammation markers and infarct size markers. The study population consisted of 75 patients with ST-segment elevation myocardial infarction (STEMI) and 57 patients with normal coronary arteries (NCA) (control group). Patient characteristics, serum serglycin levels, high-sensitivity C-reactive protein (hs-CRP) levels, peak troponin T levels and other biochemical parameters were recorded. A p value <0.05 was considered statistically significant. The control group consisted of individuals who are younger and smoke less than those of the STEMI group. The number of females in the control group was higher than in the STEMI group. Serum serglycin levels were significantly higher in the STEMI group than in control group (102.81±39.42 vs. 57.13±32.25, p<0.001). Correlation analyses revealed a significant positive correlation between serglycin and troponin (Spearman's Rho 0.419; p<0.001) and between serglycin and hs CRP (Spearman's Rho 0.336; p<0.001). Multivariate logistic regression analysis demonstrated that serum serglycin levels were independently associated with STEMI. Using a cutoff level of 80,47 μg/L, the serglycin level predicted the presence of STEMI with a sensitivity of 75.7% and specificity of 68.4%. Serum serglycin levels were significantly higher in the STEMI group than in the control group. Serum serglycin levels were positively correlated with both hs CRP levels and troponin levels. Serum serglycin levels were significantly higher in the STEMI group than in the control group. Serum serglycin levels were positively correlated with both hs CRP levels and troponin levels.
