Retrospectıve evaluatıon of operatıon rısk analysıs ın CABG performed patıents over 75 years of age

Age is an important risk factor in development of Coronary Artery Disease (CAD). In our country, it is increasing with the demographic difference of the society as in whole world. We aimed to determine the grade of mortality and morbidity risks in our study by evaluating gender of the patients aged 75 years old and over included in our study, presence or absence of preoperative renal disfunction, cross duration during operation, bypass duration, and intensive care periods in the postoperative period. It was observed that lenght of stay in the intensive care unit was longer for female patients according to gender and that bypass and cross-clemp durations increased in parallel with increase in number of veins according to number of vascular classes. As a result of 1 unit increase hospitalization duration in intensive care unit, mortality risk will increase 1.697 times (69.7%). Renal impairment was found to be a significant variable affecting mortality. It was seen that those with renal impairment had a mortality risk of 12,875 times higher than those without.
