Introduction and objectives

Evaluating 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).

Methods

From 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.

Results

In-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 鈮?0 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 鈮?0 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.

Conclusions

Mid-term survival after discharge was highly satisfactory. Mid-term mortality varied with age and other pre- and postoperative factors.
