“心绞痛”仅是对主观疼痛症状的描述,缺少客观指标。典型心绞痛通常因体力劳动、精神紧张诱发,用硝酸甘油或休息可绥解,呈反复发作性胸骨后绞窄样疼痛,部分病人发作时 ST 段降低;所谓变异型心绞痛(VAP)乃1959年 Prinz-mctal 首先提出的相对典型心绞痛而言的特殊类型,发作时伴 ST 段抬高。近年来冠状动脉(CA)造影证明 CA 痉挛是VAP 发作的重要因素。其临床表现复杂多样,竟有“变异的变异”之称。很难根据临床征象推断其病变严重程度及指导治疗,CA 狭窄程度极为不一,预后差异甚大。
“Angina” is only a description of the subjective pain symptoms, the lack of objective indicators. Typical angina usually due to manual labor, mental stress induced by nitroglycerin or rest can be resolved, was recurrent post-stenosis like sternum, ST segment decreased in some patients attack; so-called variant angina (VAP) is 1959 Prinz The first type of m-relative was proposed for a specific type of typical angina pectoris with episodes of ST-segment elevation. Coronary artery (CA) angiography in recent years proved that CA spasm is an important factor in the onset of VAP. The clinical manifestations of complex and diverse, as the “variation of variation,” said. It is difficult to infer the severity of the disease and guide the treatment based on clinical signs, the degree of CA stenosis is very different, the prognosis is very different.
