Ninety patients with angiographically confirmed diagnosis of coronary heart disease were examined. The ECG exercise test and Holter ECG monitoring were carried out. Silent ischemia (SI) was revealed in 40 patients (44.4%). According to the data of examinations, the patients with SI episodes were clinically graver than those without SI. In the SI group, 60% of the patients had prognostic criteria of a clinically high coronarographic risk, namely stenosis of the trunk of the left coronary artery, dangerous localisation of one or more arteries in "incomplete" myocardial infarction, and significant sclerosis of three main coronary arteries. Practically all the patients were at high risk for SI episodes. The probability of a high risk increases if SI is associated with such factors as the total ischemic burden of more than 30 minutes and ST depression magnitude equal to 1.5 mm in the ECG exercise test or 3 mm in Holter ECG monitoring.
对90例经血管造影确诊为冠心病的患者进行了检查。进行了心电图运动试验和动态心电图监测。40例患者（44.4%）发现有静息性缺血（SI）。根据检查数据，发生SI发作的患者临床病情比未发生SI的患者更严重。在SI组中，60%的患者具有临床冠状动脉造影高风险的预后标准，即左冠状动脉主干狭窄、在“非完全性”心肌梗死中一条或多条动脉的危险定位以及三条主要冠状动脉的明显硬化。实际上所有患者都有发生SI发作的高风险。如果SI与诸如总缺血负荷超过30分钟以及心电图运动试验中ST段压低幅度等于1.5毫米或动态心电图监测中等于3毫米等因素相关，则高风险的概率会增加。
