INCIDENCE OF MYOCARDIAL INFARCTION AFTER OPEN HEART SURGERY

Abstract

Background: One of the most common surgical procedures performed today is open heart surgery, and with it comes complications. One of these complications is post-operative myocardial infarction (MI), and others are post-operative stroke, neurological problems, wound infection, respiratory complications, etc.<br />Methods: This prospective study included 424 patients who underwent open heart surgery at our center between November 2005 and May 2006. All relevant clinical, electrocardiographic, echocardiographic, and laboratory data were gathered in all the patients, and the patients were observed for the development of MI after surgery.<br />Results: Post-operative MI occurred in 45 (10.8%) patients. By the univariate analysis, systemic hypertension, on-pump surgery, and increased serum levels of LDL cholesterol and triglycerides (TG) were significantly associated with the occurrence of post-operative MI (all P-values<0.05).<br />Conclusion: The results of the present study demonstrated that systemic hypertension, on-pump surgery, and serum levels of LDL and TG were related to post-operative MI. Therefore, clinical data, laboratory data, ECG, and echocardiography may be useful in the risk stratification of high-risk patients for the occurrence of post-operative MI
