1. É sempre necessário solicitar um eletrocardiograma antes de prescrever um antidepressivo tricíclico?
Não há necessidade absoluta de solicitar eletrocardiograma (ECG) antes de prescrever um antidepressivo tricíclico. Pacientes sem fatores de risco para morte súbita e em uso de doses baixas de tricíclicos (abaixo de 100 mg/dia de amitriptilina, imipramina e clomipramina e abaixo de 62,5 mg/dia de nortriptilina,) não necessitam realizar um ECG antes d

2. Is Frailty Syndrome a Predictor of Morbimortality in Postoperative Cardiac Surgery? – A Retrospective Cohort Study
Abstract Background Frailty is a biological syndrome suggested as a better predictor of morbimortality than chronological age. Objective To assess associations between frailty and morbimortality outcomes in postoperative cardiac surgery. Methods A retrospective cohort study was conducted with cardiac surgery patients. Frailty and maximal inspiratory pr

3. Short-Term Results of Ivabradine versus Metoprolol: The Effects on Atrial Fibrillation in Patients Undergoing Off-Pump Coronary Artery Bypass Grafting
ABSTRACT Introduction: Classic coronary artery bypass grafting (CABG) surgery involves diastolic cardiac arrest under cardiopulmonary bypass, while off-pump CABG (OPCABG) has become widespread in recent years. Methods: 174 patients who underwent OPCABG were included in the study. Patients were divided into two groups. Group I (n=90) received ivabradine and

4. Cardiovascular Physiotherapy on Respiratory Sinus Arrhythmia of Patients Undergoing Coronary Artery Bypass Grafting
Abstract Introduction: Patients in the postoperative period of coronary artery bypass grafting (CABG) present respiratory and autonomic dysfunctions. In this sense, cardiovascular physiotherapy has been offered as an indispensable differential for the improvement of the prognosis of this population. Heart rate variability is a simple, noninvasive method to

5. Does Decreased SNX10 Serve as a Novel Risk Factor in Atrial Fibrillation of the Valvular Heart Disease? - A Case-Control Study
Abstract Introduction: Atrial fibrillation (AF) is the most common sustained arrhythmia. Sorting nexin 10 (SNX10) has been reported to be an important regulator in embryonic development and human diseases, however, little is known about its role in cardiac disease. The aim of this study was to investigate the clinical significance of SNX10 expression in AF.

6. O que esperar da nova proposta de reforma administrativa: uma análise da Proposta de Emenda à Constituição (PEC) 32/20
Abstract Background The importance of regional sympathetic denervation in the pathophysiology and prognosis of Chagas disease has been recognized. Objective To conduct a review of studies that have assessed dysautonomia in chronic Chagas heart disease. Methods The search was performed on the Medline, Pubmed, Lilacs and SciELO databases. The inclusion c

8. Occurrence of recently diagnosed atrial fibrillation in the immediate postoperative period of myocardial revascularization surgery. Although common, a devalued complication
SUMMARY Atrial fibrillation (AF) is the most common arrhythmia in the postoperative period of cardiac surgery, with a prevalence between 15-40% after coronary artery bypass surgery (CABG). Several strategies have been tested for the prevention and management of AF postoperatively. Previous studies and analysis of records have shown higher rates of hospitaliz

9. GDF11 ameliorated myocardial ischemia reperfusion injury by antioxidant stress and up-regulating autophagy in STZ-induced type 1 diabetic rats
Abstract Purpose: To investigate whether GDF11 ameliorates myocardial ischemia reperfusion (MIR) injury in diabetic rats and explore the underlying mechanisms. Methods: Diabetic and non-diabetic rats subjected to MIR (30 min of coronary artery occlusion followed by 120 min of reperfusion) with/without GDF11 pretreatment. Cardiac function, myocardial infarc

10. Hyperkalemia in chronic kidney disease
RESUMO A hiperpotassemia é um achado frequente em pacientes com doença renal crônica (DRC). Esta elevação do nível sérico de potássio está associada à diminuição da excreção renal do íon, assim como ao uso de medicações para retardar a progressão da DRC ou para controlar doenças associadas, como diabetes mellitus e insuficiência cardíaca

11. The Effect of High-Dose Vitamin C on Biochemical Markers of Myocardial Injury in Coronary Artery Bypass Surgery
Abstract Objective: To evaluate the effect of high-dose vitamin C on cardiac reperfusion injury and plasma levels of creatine kinase-muscle/brain (CK-MB), troponin I, and lactate dehydrogenase (LDH) in patients undergoing coronary artery bypass grafting (CABG). Methods: This is a double-blind randomized clinical trial study. Fifty patients (50-80 years old

12. Outbreaks of nutritional cardiomyopathy in pigs in Brazil
RESUMO: Cardiomiopatia dilatada (CMD) é uma condição que afeta o miocárdio, raramente relatada em porcos. A DCM é caracterizada por dilatação ventricular, que resulta em disfunção sistólica e disfunção diastólica secundária e pode levar a arritmias e insuficiência cardíaca congestiva fatal. Este estudo descreve os achados clínicos, patológi
