冠状动脉痉挛不仅是引起变异型心绞痛的重要因素,也是引起非劳累型心绞痛、劳累型心绞痛和急性心肌梗塞的重要因素。然而,冠状动脉痉挛的确切机理仍未阐明。已有报道酒精可诱发变异型心绞痛发作。本文就饮酒与变异型心绞痛的关系作一研究。方法:15例经冠状动脉造影检查证实的变异型心绞痛患者,住院作酒精试验,给予含16%酒精的饮料100～360毫升或含4.5%酒精的啤酒500～630毫升。试验前至少3天停用除硝酸甘油外的其他药物,试验前2小时硝酸甘油也停止使用。每例患者最少应进行该试验二次。凡下列标准之一出现 Coronary artery spasm is not only an important factor causing variant angina, but also an important factor causing non-exertion angina pectoris, angina pectoris and acute myocardial infarction. However, the exact mechanism of coronary artery spasm remains unclear. It has been reported that alcohol can induce variant angina pectoris. This article studies the relationship between alcohol consumption and variant angina. Methods: Fifteen patients with variant angina pectoris confirmed by coronary angiography were hospitalized for alcohol test and were given 100-360 ml of alcohol with 16% alcohol or 500-630 ml of beer containing 4.5% alcohol. At least 3 days before the test disable other drugs other than nitroglycerin, 2 hours before the test nitroglycerin also stopped using. The test should be performed at least twice per patient. One of the following criteria appears
