Abstract Background Wolff-Parkinson-White (WPW) syndrome is characterized by ventricular pre-excitation, which can lead to severe arrhythmic events such as supraventricular tachycardia and pre-excited atrial fibrillation. The diagnostic value of non-invasive exercise tests in detecting high-risk accessory pathways remains inconsistent in the literature. Objectives To evaluate the diagnostic accuracy of non-invasive exercise tests compared to invasive electrophysiological studies (EPS) for identifying high-risk accessory pathways in WPW syndrome. Methods Following PRISMA-DTA guidelines, a comprehensive search was conducted in PubMed, Scopus, and Web […]

Abstract Background Strict blood pressure control has been investigated as a strategy to reduce severe cardiovascular events in patients with hypertension. However, there are still doubts about the impact of intensive antihypertensive treatment goals (< 130/80 mmHg) compared to conventional goals (≥ 130/80 mmHg) in preventing myocardial infarction, stroke, mortality, and possible treatment-related adverse effects. Objective To evaluate the effectiveness of intensive antihypertensive treatment goals in reducing critical cardiovascular events compared to usual goals. Methods This systematic review included randomized […]

Abstract Background Obesity is associated with the development of cardiovascular diseases and is a serious public health problem. In animal models, high-fat diet (HFD) feeding impairs cardiac structure and function and promotes oxidative stress and apoptosis. Resistance exercise training (RT), however, has been recommended as coadjutant in the treatment of cardiometabolic diseases, including obesity, because it increases energy expenditure and stimulates lipolysis. Objective In this systematic review, we aimed to assess the benefits of RT on the heart of rats […]

Abstract Background Randomized controlled trials (RCTs) and observational studies have compared the efficacy and safety of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in patients with severe aortic stenosis. Objectives Compare TAVR and SAVR in patients with different surgical risks, population characteristics, and different transcatheter prosthetic valves. Methods An overview of systematic reviews (SRs) was conducted following a structured protocol. Results were grouped by surgical risk, population characteristics, and different valves. RCTs in the SRs were […]

Abstract Background: Most cardiovascular deaths occur in low- and middle-income countries and myocardial infarction is one of the main life-threatening conditions. Objective: We assessed all-cause in-hospital mortality in patients admitted for myocardial infarction (STEMI and NSTEMI) in Latin America and the Caribbean from 2000 onward. Methods: We systematically searched in electronic bibliographic databases for cohort studies which reported in-hospital mortality due to STEMI and NSTEMI. A meta-analysis was performed and a p-value < 0.05 was considered significant. Results: We identified [...]

Abstract Background Clinical reasoning is at the core of medical practice and entangled in a conceptual confusion. The duality theory in probability allows to evaluate its objective and subjective aspects. Objectives To conduct a systematic review of the literature about clinical reasoning in decision making in medical education and to propose a “reasoning based on the Bayesian rule” (RBBR). Methods A systematic review on PubMed was conducted (until February 27, 2022), following a strict methodology, by a researcher experienced in […]
