    Abstract:
    INTRODUCTION: The objective of this study was to examine the occurrence of asymptomatic myocardial ischemia prior to and after myocardial revascularization in patients with multivessel occlusive coronary disease. Asymptomatic ischemia can be described as real ischemia without anginal pain or other ischemic symptoms in patients with coronary disease or coronary artery spasm. Our study examined silent ischemia after myocardial revascularization. Early detection of silent ischemia is important for prevention of cardiac incidents. MATERIAL AND METHODS: We have examined patients with multivessel coronary disease with occurrence of continued preoperative silent ischemia. All patients have undergone ECG examination, exercise stress test and Holter-monitoring prior to and after myocardial revascularization. RESULTS: The investigation comprised 27 patients and their average age was 54.5 years. All patients with silent ischemia had a multivessel occlusive coronary disease and have undergone myocardial revascularization managed with triple or quadruple aortocoronary bypass surgery. Exercise stress test was performed postoperatively in elder patients, as well as ECG and Holter-monitoring. Silent ischemia was established in 21.6% of patients, while in 87.5% untreated diabetes mellitus was diagnosed. Silent ischemia most often occurred in the early morning hours and it was frequently associated with heart rhythm disturbances (VES) whereas these rhythm disturbances depended on the length of the ischemic episode. Intermittent 2nd degree atrioventricular block was found in one patient. CONCLUSION: Silent myocardial ischemia occurred in 21% of patients after myocardial revascularization. It is most often detected in the early morning hours and is associated with ventricular rhythm disorders. Silent ischemia is easily detected by simple examination procedures providing adequate therapy and prevention of cardiac incidents.
