Comparación entre la fibrilación auricular de novo y la mortalidad en pacientes sometidos a cirugía de revascularización miocárdica entre pacientes de 50 a 80 años en el Hospital Alcívar período 2020 – 2022.

Abstract

Post-surgical atrial fibrillation is the cardiac arrhythmia that occurs most frequently after open-heart intervention, it can occur in up to 50% of these patients, and it is associated with multiple adverse effects. The objective of this study was to determine the relationship between postoperative AF and mortality in patients undergoing cardiac surgery at Hospital Alcívar during the period January 2020 - December 2022. Methodology: Descriptive, retrospective, observational study with a nonexperimental design. Results: 151 patients undergoing cardiac surgery were included, of which 23.8% presented postoperative or de novo atrial fibrillation, ejection fraction <40% was related to the development of de Novo AF (p<0.01) on the other hand, de novo AF was related to a longer hospital stay and mortality (p<0.01). Conclusions: De novo or postoperative AF is the most common arrhythmia that occurs after cardiac intervention and is strongly associated with adverse effects such as longer hospital stay and increased mortality.
