Fibrilación auricular en pacientes con estenosis mitral del Hospital General Monte Sinaí en el periodo 2022-2025.

Abstract

Introduction: Atrial fibrillation (AF) is the most frequent arrhythmia in the world. By 2030, cases are expected to rise to 12 million, with 1.8 to 2.6 million new cases annually. Among valvular diseases, mitral stenosis (MS) is the most frequent. AF is the most frequent complication in patients with MS, occurring in approximately 40% of patients. The aim of the study is to estimate the prevalence of atrial fibrillation in patients with mitral stenosis seen at Mount Sinai General Hospital in the period from January 2022 to January 2025. Methodology: This is a descriptive study with a mixed approach and a non-experimental, cross-sectional, and retrospective design. The universe focuses on all patients with mitral stenosis at Mount Sinai General Hospital during 2022-2025. Inferential analysis was performed using chi 2 and t distribution. Results: We obtained 246 patients with the diagnosis of mitral stenosis of which 164 had described atrial fibrillation. The predominant sex was female, and the mean age was 61.07 ± 14.42. Diabetes was the most frequent comorbidity (84.8%). Dyspnea was present in more than 90% of cases. Paroxysmal AF was the most common arrhythmia. MS stage B was the most prevalent in patients with MS and AF. Conclusions: Further studies are needed to better understand the relationship of atrial fibrillation and mitral stenosis.
