Comparison of the electrocardiographic, clinical and coronarographic data in ischemic heart disease after physical exertion]

A comparison of the clinical data and those of ECG under physical exercises with the results of coronary angiography is presented for 130 patients with the ischaemic heart disease, aged 28 to 68 years; 63 of them had survived myocardial infarction, 63 had angina of effort, 65--angina at rest and angina of effort, 2 presented no complaints. The comparison of the clinical and coronarographic data demonstrated a high correlation in cases of angina; in 85.3% of the patients with typical angina pectoris coronary angiography revealed anatomic changes in the coronaries. Having compared the data to the positive exercise test with the results of coronary angiography, the authors found that 87.9% of the examined patients have--with a positive exercise test--coronary lesions and the S--T segment depression during physicial exercises 1 mm below the iso-electric line, which permits to diagnose anatomic changes in the coronaries. According to the authors, an acute onset of the disease, a brief history (up to 1 year) and a prompt restoration of the ECG following physical exercises are typical rather for local lesions of one coronary branch.
