Fibrilación auricular como factor pronóstico en pacientes ingresados con insuficiencia cardíaca aguda descompensada en el Hospital Luis Vernaza de Guayaquil, desde octubre del 2017 al mes de julio del 2018.

Abstract

Introduction: Atrial Fibrillation (AF) is an important cause of morbidity and mortality in patients with Acute Heart Failure (AHF). It affects around 1% to 2% of the Ecuadorian population, being one of the most common reasons for consultation in the emergency services, representing a high expenditure at the health level. The association of these two pathologies represent a high mortality rate. Objective: To analyze whether atrial fibrillation in patients with decompensated acute heart failure predicts a higher mortality rate in hospitalized patients in the period from October 2017 to July 2018. Methods and Materials: An observational, analytical and retrospective study was made. The data was obtained by reviewing electronic medical records of patients diagnosed with decompensated acute heart failure admitted to the Hospital Luis Vernaza de Guayaquil from October 2017 to July 2018. Results: 57.8% of admitted patients, are in functional class III of the NYHA. The AF predominates more in women than in men; 54.7% vs 45.3% respectively. Patients between 76 and 85 years of age have a high risk of mortality with high NT pro BNP levels (p 0.045). Conclusions: A higher level of NT pro BNP increased NYHA functional class. Regarding the mortality rate in patients with and without AF, there was a tendency of association, without being statistically significant. Finally, it can be concluded that AF is not a prognostic factor in mortality in patients with AHF.
