Ninety-five coronary patients were studied, including 44 patients with stable angina and 51 with unstable angina. All patients underwent bicycle ergometry and the intravenous ergometrin test. An anginal attack developed in response to bicycle ergometry in 63.5% of patients with stable angina and in 74.4% of patients with progressive coronary insufficiency. The threshold capacity achieved was directly related to the functional class of stable angina, and dependent on the clinical variety of unstable angina. The ergometrin test was positive in 70.4% of patients with stable angina and 82.4% of patients with unstable angina. An ergometrin-induced anginal attack developed where the double product was significantly smaller than that of threshold stress. The differences were the highest in patients with progressive angina and attacks of acute coronary insufficiency.
对95例冠心病患者进行了研究，其中包括44例稳定型心绞痛患者和51例不稳定型心绞痛患者。所有患者均接受了踏车运动试验和静脉注射麦角新碱试验。在稳定型心绞痛患者中，63.5%的患者在踏车运动试验中诱发了心绞痛发作，在进行性冠状动脉功能不全患者中，这一比例为74.4%。达到的阈能力与稳定型心绞痛的功能分级直接相关，并取决于不稳定型心绞痛的临床类型。麦角新碱试验在70.4%的稳定型心绞痛患者和82.4%的不稳定型心绞痛患者中呈阳性。在双倍乘积明显小于阈应力的情况下，会发生麦角新碱诱发的心绞痛发作。在进行性心绞痛和急性冠状动脉功能不全发作的患者中，差异最为明显。
