Abstract: | AIM: To assess extent and localization of coronary artery lesions in patients with painless myocardial ischemia. MATERIAL AND METHODS: Tredmill stress-echocardiograghy, Holter ECG monitoring and coronary angiography were carried out in 59 male patients (age 30-72, mean 54.5 years) with either angina pectoris or painless ischemia. RESULTS: Among patients with painless ischemia 50% had 2-vessel disease, mostly with right coronary artery involvement (87.5%) and there was no case of left main stenosis. Patients with angina were characterized by significantly higher index of obstruction (p<0.005) and often had multivessel coronary artery disease (48.8%). CONCLUSION: Patients with effort angina compared with those with painless ischemia had more extensive and severe coronary artery involvement while the latter more often had right coronary artery stenoses. |
