Prevalencia de fibrilación auricular en pacientes con insuficiencia cardiaca mayores de 45 años atendidos por el servicio de cardiología en el Hospital General del Norte de Guayaquil Los Ceibos durante el año 2021.

Abstract

Introduction: Atrial fibrillation (AF) is considered the most frequent arrhythmia worldwide, and is related to an increased risk of death, stroke and peripheral embolism. It is a condition in which the upper chambers of the heart (atria) beat irregularly and rapidly, causing poor blood flow to the rest of the body. HF is a clinical syndrome characterized by its signs and symptoms in response to structural or functional deterioration in the ventricle, these being the difficulty in filling or expelling. Methods: A retrospective and observational crosssectional study conducted at the General Hospital del Norte IESS Los Ceibos, in which the reported cases of heart failure in addition to atrial fibrillation during the 2021 period were reviewed. Results: Data were collected from 322 patients who met the inclusion criteria. Of these, 72% were women. The most common comorbidity was hypertension (91.9%), followed by ischemic heart disease with 199 patients within the sample (61.8%) and in third place type 2 diabetes (38.2%). Conclusion: There is a high prevalence of atrial fibrillation in patients with an established diagnosis of heart failure who were treated by the cardiology service at the IESS hospital, this being a value of 55.5%. Hypertension was considered the most frequent comorbidity, occurring in 164 of 178 patients with atrial fibrillation.
