1. Effects of Hyperthyroidism on Contractility and Na+/Ca2+ Exchanger Activity in the Isolated Papillary Muscle of Rats
Abstract Background: Hyperthyroidism (Hy) is an endocrine disorder, in which the thyroid hormones markedly alter the cardiac function. Increased myocardial contractility and cardiac output, improvement in diastolic relaxation, changes in electrical activity, increments in ventricular mass, and arrhythmias have been reported. However, the influences of thyro

2. Application of Mivacurium in Fast-Track Anesthesia for Transthoracic Device Closure of Ventricular Septal Defects in Children
Abstract Introduction: The objective of this study was to investigate the effect of mivacurium in the application of fast-track anesthesia for transthoracic device closure of ventricular septal defects (VSDs) in children. Methods: The data of 108 children who underwent transthoracic device closure of VSDs from December 2018 to June 2020 were recorded and a

3. Acute Myocardial Infarction and Percutaneous Coronary Intervention: What does the Epidemiological Data of the Last Years Indicate?
Abstract Background: ST-segment elevation acute myocardial infarction (STEMI) is a pathological process that involves cardiac muscle tissue death. Intravenous thrombolysis with fibrinolytics or primary percutaneous coronary intervention (PCI), an invasive technique, can be performed for tissue revascularization. PCI has been preferred as compared to non-inv

4. Short-Term Effects of a Resistance Training Program Using Elastic Tubing in Patients with Heart Disease
Abstract Background Resistance training is effective in cardiac rehabilitation; however, it is conventionally performed using free weights or machines, which can pose logistic challenges to patients with restricted mobility. For its ease of access and cost-effectiveness, elastic tubing is a particularly appealing alternative, but it remains underutilized fo

5. Effects of Inspiratory Muscle Training Using an Electronic Device on Patients Undergoing Cardiac Surgery: A Randomized Controlled Trial
Abstract Background Cardiac surgery causes pathophysiological changes that favor the occurrence of pulmonary and functional complications. Objective To investigate the effects of inspiratory muscle training (IMT) with an electronic device on patients undergoing cardiac surgery. Methods A randomized controlled trial was conducted with 30 adult patients

6. Correlation between Surgical Risk Scales with Respiratory Muscle Strength and Functional Independence in Patients Submitted to Coronary Artery Bypass Grafting
Abstract Background The European Heart Surgery Risk Assessment System (EuroSCORE) and InsCor have been used to predict complications of cardiac surgery. However, their application to predict lung function and functionality is still uncertain. Objective To correlate surgical risk scales with functional independence and pulmonary function in patients under

12. INFLUENCE OF CREATINE KINASE ON C-REACTIVE PROTEIN IN MUSCLE ADAPTATION
RESUMO Introdução O envelhecimento é um processo natural e marcado por mudanças e adaptações, tanto biológicas quanto fisiológicas. Com relação às adaptações, existem inúmeros trabalhos que abordam essas respostas decorrente a vários tipos de treinamento. O treinamento resistido (TR) pode ser avaliado por parâmetros bioquímicos, como a cre
