Abstract Duchenne muscular dystrophy (DMD) is a muscular disease genetically linked to the DMD gene, which encodes dystrophin, a protein that is crucial for the integrity of skeletal muscle and myocytes. This condition follows an X-linked inheritance pattern. Female carriers are typically asymptomatic; however, they may develop cardiomyopathy, making screening for structural heart disease advisable. We conducted a cross-sectional study to assess the prevalence of subclinical left ventricular (LV) dysfunction, defined by reduced global longitudinal strain (GLS), in asymptomatic female […]

Abstract Background: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with heart failure. Objective: To evaluate the response of CRT in maximal inspiratory pressure (MIP), peak expiratory flow (PEF), and exercise tolerance as determined by the six-minute walk test (6MWT) in patients with HF. Methods: This study used the 6MWT and Manovacuometer to assess functional capacity in relation to activities of daily living, in which fatigue and dyspnea are common. Results: After six months of CRT, this study […]

Abstract Background Increasing thoracic expansion is effective at reducing blood pressure in hypertensive subjects. Yoga prescribes many respiratory techniques with a growing number of practitioners. However, very little is known whether sedentary or yoga practitioners show measurable differences in their respiratory patterns. Objective This study aims to demonstrate differences between healthy sedentary individuals and healthy yoga practitioners regarding maximal respiratory pressures and thoracic and abdominal respiratory expansibility. Methods Maximal inspiratory and expiratory pressures (MIP and MEP, respectively) were evaluated by […]

Abstract Background: Nasal mucociliary clearance (NMC) responds to autonomic activity through exercise. However, there is a gap in the literature on how NMC responds to resistance exercise. Objective: To evaluate the acute effects of resistance tube exercise on NMC and the autonomic nervous system in smokers. Methods: Clinical trial was performed with 18 individuals. Personal, anthropometric, and smoking history data were collected, and a pulmonary function test was performed by spirometry. The fatigue resistance test was performed in order to […]

The initiative to make an edition dedicated to a certain area of knowledge in a scientific journal is always a major challenge full of hard work. Original articles, reviews and / or special cases in the field are expected and the best experts in the subject are those that the editor hopes to be able to count. This edition of the International Journal of Cardiology Science, headed by Dr. Claúdio Gil Soares de Araújo, is focused on physical exercise and […]

Abstract The primary goal of coronary artery bypass grafting is to achieve complete revascularization with grafts that will remain patent throughout the patient’s lifetime. This study investigated the association between bypass graft patency and comorbidity burden determined by Charlson comorbidity index (CCI) among patients with previous bypass operation who underwent a control angiography. One-hundred and two patients who had undergone CABG in the past were included to the study. Critical stenosis was defined as 50% or greater coronary luminal obstruction […]

Introduction Obstructive sleep apnea syndrome (OSAS), a chronic, progressive disease, with high mortality and morbidity, which has been associated with cardiovascular diseases, including heart failure (HF). The pathophysiological changes related to OSAS and its contribution to cardiovascular risk are consequences of increased sympathetic activity, increased oxidative stress, pro-inflammatory changes and endothelial dysfunction. […]

Abstract Children and adolescents infected by HIV through mother-to-child transmission are at high risk of developing premature cardiovascular diseases due to dyslipidemia, insulin resistance and low-grade chronic inflammation. The aim of the pilot study was to verify the effect of a playful exercise program on cardiovascular, morphological, metabolic, fitness, and quality of life outcomes. A non-randomized clinical trial consisting of 24 sessions of playful aerobic and resistive exercises was applied to 10 children and adolescents living with HIV from Florianopolis, […]
