Introduction And ObjectivesEvaluating patient outcomes following cardiac surgery is a means of measuring the quality of that surgery. The present study analyzes survival and the risk factors associated with mid-term mortality of patients undergoing cardiac surgery in Son Dureta University Hospital (Palma, Balearic Islands, Spain).MethodsFrom November 2002 thru December 2007, 1938 patients underwent interventions. Patients were stratified in 4 age groups. Of 1900 patients discharged from hospital, 1844 were followed until December 31, 2008. Following discharge, we constructed Kaplan-Meier survival curves and performed Cox regression analysis to determine which variables associated with mid-term mortality.ResultsIn-hospital mortality of the 1,938 patients was 1.96% (CI 95%, 1.36%-2.6%). Survival probability at 1, 3 and 5 years follow-up was 98%, 94% and 90%, respectively. Mean follow-up was 3.2 (0.01-6.06) years. Patients aged ≥ 70 years showed a lower survival rate than those aged <70 (log rank test, P <.0001). At the end of follow-up, mortality was 6.5% (CI 95%, 5.4%-7.7%). Age ≥ 70 years, a history of severe ventricular dysfunction (ejection fraction < 30%), severe pulmonary hypertension, diabetes mellitus, preoperative anemia, postoperative stroke, and hospital stay were independently associated with mid-term mortality.ConclusionsMid-term survival after discharge was highly satisfactory. Mid-term mortality varied with age and other pre- and postoperative factors.Copyright © 2010 Sociedad Española de Cardiología. Published by Elsevier Espana. All rights reserved.
