Abstract Background: Arterial hypertension is a multisystem disease that increases the risk of fatal cardiac events. Objectives: This study aims to determine the prevalence of increased blood pressure levels of pre-adolescents and adolescents and correlate these pressure levels with the presence of overweight or obesity and family history of hypertension. Methods: In an observational, cross-sectional study, a sample of 157 students from the city of Petropolis aged from ten to nineteen was randomly selected. The study included four public schools […]

Abstract Background: Coronary heart disease is a public health problem, and the leading cause of premature death in Europe and worldwide. There is epidemiological evidence that the control of cardiovascular risk factors following myocardial revascularization remains suboptimal. Objectives: Analyze the incidence of cardiovascular events in patients receiving secondary prevention therapies after myocardial revascularization. Methods: Single-center study on consecutive coronary patients retrospectively identified, conducted at the Institute of Cardiovascular Diseases in Timisoara, Romania. Patients with diagnosis of revascularization for coronary artery […]

Abstract Background: Left bundle branch block (LBBB) has prognostic significance in patients with congestive heart failure. However, its influence is not well established in patients with preserved systolic ventricular function. Objective: To evaluate the implications of LBBB presence in the cardiovascular performance of patients with preserved left ventricular systolic function (LVEF). Methods: 26 LBBB patients (61.3 ± 8.2 years of age) and 23 healthy individuals (58 ± 6.8 years of age) with LVEF > 0.5 underwent cardiopulmonary exercise testing (CPET). […]

Abstract Background: Resistance training promotes cardiovascular health benefits that may affected by sleep deprivation. Objective: To evaluate the effect of high-intensity resistance training on myocardial contractility in rats subsequently subjected to paradoxical sleep deprivation. Methods: Forty male Wistar rats were distributed into control group (CTRL), resistance training (REST), 96-hour paradoxical sleep deprivation (PSD96) and resistance training followed by 96-hour paradoxical sleep deprivation (REST/PSD96). The animals underwent high-intensity resistance training for 8 weeks, 5x/week. Twenty-four hours after the last training session, […]

Abstract Background: To date, several validated patient-based risk scores have been established to predict mortality and morbidity in patients presenting with ST-segment elevation myocardial infarction (STEMI). The Gensini score was originally developed to quantify the severity of coronary artery disease (CAD). Objectives: We intend to assess the association between severity of CAD assessed by Gensini score and in-hospital mortality in patients with STEMI undergoing primary percutaneous coronary intervention (P-PCI). Methods: A total of 539 patients presenting with acute STEMI, who […]

Abstract Background: There is a discrepancy between protocols used for the diagnosis of childhood hypertension, and the most recommended one is the measurement of blood pressure in at least three different moments. Objective: To identify the prevalence of hypertension in children, and to associate it with the nutritional status variable. Methods: This is a longitudinal study, which included all children aged 7 to 10 years enrolled in public schools and had the authorization of their parents/guardians, totaling 722 children. In […]

Abstract Background: Hypertension is a clinical condition of multifactorial etiology that imposes serious harm to the health of elderly individuals. Despite the fact that cardiovascular disorders influence the development of hypertension in this age group, several other genetic and environmental factors have been described in the literature, including the polymorphic variant of the angiotensin-converting enzyme (ACE) gene and the distribution of body fat. Objective: To assess the prevalence of hypertension among elderly individuals and its possible correlation with the I/D […]

Abstract Background: Patients submitted to cardiac resynchronization may develop response patterns that are higher than expected, with normalization of clinical and echocardiographic parameters. Objective: To analyze the clinical and echocardiographic characteristics of this population of super-responders, comparing them with the other patients submitted to cardiac resynchronization therapy. Methods: A prospective, observational cohort study involving 146 patients consecutively submitted to cardiac resynchronization implants. Fisher’s exact test and Mann-Whitney test were performed to compare the variables. Patients with ejection fraction > 50% […]
