Aim: To evaluate the role of preoperative cardiac risk factors, cardiac enzymes and ECG on cardiac morbidity in males, older than 40, who planned to have thoracic surgery. Material and Methods: With the consent of ethical committee, this prospective study was performed on forty males, older than 40, who scheduled for elective thoracic surgery. The cases with at least one of the preoperative cardiac risk factors were included. Standard anesthesia was achieved for all of the cases. Blood pressure, heart rate, ECG and SpO2 were monitored. ECG, troponin I, CK-MB and CPK levels were recorded in preoperative and postoperative (in 24. / 48. hours) periods. Intraoperative haemodynamic deteriorations and postoperative changes in ECG, troponin I, CK-MB and CPK levels were determined. Results: Overall mean age of the cases was 57.1 ± 8.5 years. Totally seven cases had changes in ECG in the first or second days of their operations. Three of them had ECG changes in both days. Four of seven cases with postoperative ECG changes had multiple preoperative cardiac risk factors. Nineteen of 20 cases with intraoperative haemodynamic deteriorations had been underwent pulmonary resection. Mean operation length of the cases with postoperative ECG changes (227.1 ± 43.7 minute) was longer than the others (189.9 ± 51.6 minute) (p< 0.05). Postoperative changes in CPK levels were statistically significant in the cases with postoperative ECG changes (p< 0.05). Conclusion: We think that it is important as preoperative risk factors as cardiac enzymes and postoperative ECG records to decrease cardiac morbidity in males, older than 40, especially undergoing pulmonary resection.
