Abstract Background It has been suggested that the consumption of energy drinks (ED) may affect cardiovascular activity. Objectives to investigate the acute effects of ED intake on heart rate variability (HRV) and cardiovascular recovery after moderate aerobic exercise in males with different cardiorespiratory capacities. Methods This is a randomized, double-blind, crossover, placebo-controlled study. Twenty-eight young adults were split into two groups according to their peak oxygen consumption (VO2peak) values: (1) High VO2 peak (HO) – VO2 peak > 52.15 mL/kg/min, […]

Introduction Scientific evidence shows that the regular practice of physical exercise (PE) is beneficial for various organs and systems of the human body, mainly for the heart and cardiovascular system. In both systems, aerobic and strength PE promote physiological cardiac hypertrophy, respectively eccentric and concentric, improving myocardial function. In addition to the benefits for the heart, PE impacts blood vessels through shear stress and alters long-term vascular function, improving endothelial cell and smooth muscle cell function, generating arterial remodeling and […]

Background: Previous cross-sectional studies have demonstrated that physical activity is associated with lower cardiovascular risk in patients with peripheral artery disease (PAD). However, it is not possible to establish causality, and longitudinal design studies are required. Objective: To analyze the changes in cardiovascular risk parameters and physical activity levels after a 2-year follow-up in patients with symptomatic PAD. Methods: This study started in 2015. In the first phase, 268 patients were included. In the second phase, after 2 years (median […]

Brazil and Portugal have a great deal in common, and they are bound by strong ties, with a history that began to be written over five centuries ago. They share a language, although there are pronounced differences in accent, as well as vocabulary. Air traffic between both countries is intense (much lower during the Covid-19 pandemic), and citizens from both sides of the Atlantic Ocean inhabit or visit cities on the other side. Finally, Portuguese blood runs in the veins […]

Dear editor, I read with interest the article published by Costa et al.1 The use of statins in cardiometabolic protection promoted by physical training of moderate-intensity in an aquatic environment has been little studied, mainly from the clinical point of view. However, as described by Costa et al.,1 strength training in an aquatic environment combined with statins has been an effective increase in promoting metabolic adaptations and a reduction in lipid levels. The prognostic predictors associated with the risk of […]

Cardiovascular diseases (CVD) are responsible for approximately 19 million deaths annually in the world.In Brazil, they are involved in one third of deaths. A significant improvement in cardiovascular medicine has been observed in the last decades. However, cardiac failure, which is the final common pathway following heart injury, remains with a high incidence, prevalence, and mortality. A better understanding of CVD may allow the development of new pharmacological and non-pharmacological approaches to their treatment. In 2021, the Arquivos Brasileiros de […]

Abstract Background Patients with sickle cell disease (SCD) are at increased risk for cardiovascular complications. Exercise testing is used as a prognostic marker in a variety of cardiovascular diseases. However, there is a lack of evidence on exercise in SCD patients, particularly regarding its safety, feasibility, and possible prognostic role. Objectives We used the maximal treadmill test to determine safety and feasibility of the exercise testing in SCD patients. Additionally, the factors associated with exercise duration, as well as the […]

Abstract Background: Recurrence Plots (RP) enable a nonlinear analysis of Heart Rate Variability (HRV) and provide information on the Autonomic Nervous System (ANS). Objectives: To evaluate whether early ambulation in patients undergoing Percutaneous Transluminal Coronary Angioplasty (PTCA) influences the quantitative and qualitative components of RP. Methods: A total of 32 participants who underwent PTCA were divided into a Control Group (CG – no physical exercises) and an Early Ambulation Group (EAG – with physical exercises). Beat-to-beat heart rate was recorded […]
