心绞痛是急性心肌缺血的主要临床表现,也是诊断冠心病的重要依据之一,但有时心肌缺血可不伴有胸痛,甚至可无任何症状。无痛性急性心肌梗塞,运动试验显示典型ST段缺血性改变或冠状动脉造影示冠状动脉痉挛及ST段抬高而不伴有心绞痛等情况均为临床医师所熟悉。近年来,对无痛性心肌缺血发作的临床意义、预后及治疗等问题受到了注意,现将有关研究资料简述如 Angina pectoris is the main clinical manifestations of acute myocardial ischemia, but also one of the important basis for the diagnosis of coronary heart disease, but sometimes myocardial ischemia may not be associated with chest pain, and may even have no symptoms. Painless acute myocardial infarction, exercise tests showed typical ST-segment ischemic changes or coronary angiography showed coronary spasm and ST-segment elevation without angina and other conditions are familiar to clinicians. In recent years, attention has been paid to the clinical significance, prognosis and treatment of painless myocardial ischemia, and the related research data such as
