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.
本文呈现了130例年龄在28至68岁之间的缺血性心脏病患者的临床资料、运动时心电图数据与冠状动脉造影结果的对比情况。其中63例曾发生过心肌梗死，63例有劳力性心绞痛，65例有静息性心绞痛和劳力性心绞痛，2例无相关症状。临床资料与冠状动脉造影数据的对比显示，心绞痛患者中两者具有高度相关性；在85.3%的典型心绞痛患者中，冠状动脉造影显示冠状动脉存在解剖学改变。将运动试验阳性数据与冠状动脉造影结果进行比较后，作者发现，87.9%的受检患者在运动试验阳性时，冠状动脉存在病变，且运动时ST段压低至等电位线以下1毫米，这有助于诊断冠状动脉的解剖学改变。作者认为，疾病急性起病、病史较短（1年以内）以及运动后心电图迅速恢复正常是单支冠状动脉局部病变的典型表现。
