Electrocardiographic abnormalities in chagasic patients compared to the general population: A systematic review with updated meta-analysis.

Introduction: Chagas disease (CD) remains a serious public health issue. It can progress from the acute phase to the chronic phase, manifesting as a cardiomyopathy with some typical electrocardiogram abnormality.

Objectives: This systematic review with meta-analysis aims to evaluate the overall prevalence of cardiac arrhythmias in patients with CD and discriminative values to clinical and epidemiological variables for specific arrhythmias.

Association between reduced left ventricular ejection fraction and functional outcomes in acute stroke: Systematic review and meta-analysis.

Introduction: Left ventricular ejection fraction (LVEF) is a measure of cardiac function and often reduced LVEF is indicative of cardiomyopathy/heart failure. The current study evaluated whether reduced LVEF is associated with poor outcomes and mortality in acute stroke.

Methods: Articles that compared poor outcomes (modified Rankin scale 3-6) or mortality in people with reduced LVEF compared to preserved LVEF in acute ischemic stroke were searched in the following databases: MEDLINE/PubMed, Embase, Scopus, Biomed central, and Cochrane Library.
