Influencia de la fracción de eyección del ventrículo izquierdo en la mortalidad de pacientes mayores a 40 años sometidos a cirugía de revascularización miocárdica en el Hospital Alcívar de Guayaquil en el periodo de 2021 – 2022.

Abstract

ABSTRACT Introduction: Cardiovascular disease is the main cause of death worldwide, atherosclerotic disease of coronary vessels is the most frequent; actually, the best treatment for this disease is the revascularization, could be percutaneous or by revascularization surgery. Objective: To evaluate the influence of the left ventricular ejection fraction on the mortality of patients undergoing myocardial revascularization surgery at the Hospital Alcivar in Guayaquil in the period 2021 – 2022. Method: An observational, retrospective, cross sectional study was made in patients who undergo a myocardial revascularization surgery at the Hospital Alcivar and did analyze their mortality according to the LVEF with which they underwent this procedure. Results: The sample studied was 320 patients of which; 37.1% of patients with an FEVI <=40% died unlike patients with an FEVI >=50% and 41%-49% of which 6.60% and 6.80% of patients died respectively. The main cause of myocardial revascularization was multivessel injury, representing 98.1%. Of the risk factors analyzed, the one with the highest percentage was high blood pressure, representing 79.4%. Conclusions: the established hypothesis was corroborated by observing that mortality was 37.1% in the group of patients with reduced LVEF compared with the group of mildly reduced LVEF and preserved LVEF that was 6.8% and.
