By the first year of a follow-up, spontaneous clinical remissions (no anginal and ischemic episodes as evidenced by Holter monitoring, negative bicycle ergometric tests) in 52 (26%) out of 200 patients with primary angina pectoris. Possible predictors such as clinical signs, bicycle ergometric and coronary angiographic parameters were examined. A multifactorial stepwise discriminant analysis showed that the independent predictors of the clinical remission were heart rate and exercise power attained on bicycle ergometry, number of diseased coronary artery segments with 70% of more stenoses, disease pattern in the first month, existing and prior smoking, and myocardial infarction in the first 3 months of the disease onset.
在随访的第一年，200例原发性心绞痛患者中有52例（26%）出现自发性临床缓解（动态心电图监测未发现心绞痛和缺血发作，踏车运动试验结果为阴性）。对诸如临床体征、踏车运动试验和冠状动脉造影参数等可能的预测因素进行了检查。多因素逐步判别分析表明，临床缓解的独立预测因素为踏车运动试验时的心率和运动能力、狭窄程度达70%及以上的病变冠状动脉节段数量、疾病第一个月的类型、当前及既往吸烟情况，以及疾病发作后头3个月内是否发生心肌梗死。
