[Incidence of major adverse cardiovascular events after cardiac surgery procedures].

The aim of the study was to analyze the incidence of major adverse cardiovascular events after different cardiac surgery procedures. This study included 307 patients who underwent some of cardiac surgery procedures within a period of 6 months of arriving at stationary cardiac rehabilitation. There were 101 patients (33%) who had valve surgery and 206 patients (67%) who underwent coronary artery bypass grafting (CABG). Primary end-point was death caused by fatal myocardial infarction (MI) or sudden death, and secondary end-points were non-fatal MI or unstable angina pectoris, stroke, new cardiac surgery or percutaneous coronary intervention, heart failure or significant arrhythmia and non-cardiac death. The mean duration of follow-up period after leaving stationary cardiac rehabilitation was 35 +/- 21 months. During the follow up period, there was total of 61 primary and secondary end-points. In CABG group, there were 48 major adverse cardiovascular events compared to 13 in the group of patients with prosthetic valve (p=0.03). There was total of 19 fatal MI or sudden death (6%). The fatal outcome rates of cardiovascular origin were significantly higher in the group of patients after CABG than in the patients with prosthetic valve (16 vs. 3 death, NS). The results of this study suggest that the complications after cardiac surgery procedures occurs more often in CABG patients. However, mortality rate after cardiac surgery in the analyzed groups of patients is relatively low.
