Supervivencia a los cinco años en pacientes con valvulopatías izquierdas operados de cirugía cardíaca valvular

Introduction: The mid and long term survival rate is a necessary parameter to evaluate the outcomes of heart valve surgery. Objectives: To determine the five-year survival of patients who underwent aorticIntroduction: The mid and long term survival rate is a necessary parameter to evaluate the outcomes of heart valve surgery. Objectives: To determine the five-year survival of patients who underwent aortic and/or mitral valve surgery, and the variables that could independently predict a lower survival in the follow-up. Methods: A cohort study was conducted for evaluating 139 patients who under-went a heart valve surgery, in the period 2010-2012, at the Instituto de Cardiología y Cirugía Cardiovascular of Havana, Cuba, all of which survived the postoperative period, and were followed up to five years after the surgery. A Kaplan-Meier curve was performed to determine the survival after surgery. Also, a multivariate Cox regression was carried out to determine the variables that were dependently associated with a lower survival rate. The statistical significance level used was p
