Background: Due to the lack of reports in our country, risk factors influencing mortality in patients undergoing cardiac surgery are usually referred to, on the basis of western academic papers. In Iran this has been associated with different facilities and equipment s in different groups of populations. Thus, we have attempted to evaluate the above mentioned risk factors and their effects on mortality.
Materials and methods: All of the patients admitted for adult cardiac surgery in our center during a 15-month period (January 1999 to April 2000) were enrolled in a prospective study. Those undergoing surgery without the use of cardiopulmonary bypass (CPB) were excluded.
Results: The study population included 472 males and 273 females s%ith the mean age of 53+14.4 years (range, 16-82 years). The mortality rate was 5.2%. Factors associated with mortality were age, emergency surgery, ejection fraction, the individual surgeon operating, and the duration of CPB time. Sex, weight, body surface area, history of diabetes or hypertension, and the aortic cross clamp time didnʹt affect the mortality.
Conclusion: The overall success rate of cardiac surgery in our center is comparable to that of western societies. Emergency surgery, the individual operating surgeon, and CPB time are the associated risk factors statistically significant in mortality. Diabetes mellitus, hypertension, and duration of cross clamp time had no effect on mortality.
