Ecg Changes in Cardiac Risk Group Patients in the Perioperative Period for Noncardiac Operationsnon

Abstract

The aim of this study was to identfy the perioperative electrocardiography (ECG) changes and the predictors of cardiac complications. This pro!!ıpective study was pe,formed between January 1996 and March 1997 in Surgery Department of Medical Faculty of Gaziantep University. We studied the patients aging between 40-46 who were scheduled for elective and semielective noncardiac surgery. Patients who had definitive coronary artery disease (CAD) or high riskfor CAD on 54 patients (mean age 54±8.35) (30 Female,24 Male) Group 1 was compared with control group (Group il) on 54 patients (mean age 53±8) (21 Female, 33 Male). Preoperative riskfactors were recorded in Group 1. in each patient 12 lead ECG and cardiac spesific enzyme studies were obtained before the operation and again postoperatively on three consecutive days. in addition to the routine ECGs, serial ECG were obtained up to one week after surgery whenever a patient had postoperative cardiac signs, symptoms or changes were observed in the routine ECGs. We used Goldman and Detsky classification for evaluating the cardiac risk indexes. Perioperative ECG changes in Group 1 were compared with Group II. The incidence is significantly higher in Group I (p=0,0001) The incidences of the ischemic changes were higher in both groups (p=0,0023). Two (%3.7) out of 54 patients in Group I had clinically symptomatic, nonQ wave postoperative MI on the first operative day. These patients whose postoperative MI had preoperative ECG changes and also had coronary risk factors. in addition age, sex, the number and the types of coronary risk factors, cardiac risk index classification, site and the types of the surgery, preoperative medical problems didn't affect the rate of perioperatuar ECG changes.
