Prevalência de fibrilação atrial em pacientes em terapia renal substitutiva

Abstract

Atrial Fibrillation (AF) is a supraventricular arrhythmia in which complete disruption of atrial electrical activity occurs, the atria lose their ability to contract, and thus do not generate atrial systole. The sinoatrial node is inhibited while AF persists. Its prevalence increases with age and is commonly associated with structural heart disease, which may bring hemodynamic damage and thromboembolic complications with major economic and morbidity and mortality implications. AF is the most common supraventricular arrhythmia in chronic renal patients undergoing hemodialysis, increasing cardiovascular risk in this population. Advanced age, dialysis time, left atrial dilatation, among other factors explain the increased prevalence of AF in this population. Thus, performing anticoagulation therapy in patients undergoing renal replacement therapy has been a topic of discussion among medical literature. This project will analyze the frequency of atrial fibrillation in dialysis patients with the objective of elucidating the discussion of the importance of anticoagulation therapy in these patients. This is a quantitative, observational, cross-sectional, descriptive and analytical study that will be performed at the Nephrology Service of the Passo Fundo Clinical Hospital, RS, and the study population will consist of all patients undergoing dialysis treatment at that service in the period. of data collection. This project is relevant to the health area, as it adds evidence on the frequency of atrial fibrillation in dialysis patients, bringing benefits to the medical community, patients and their families.
