- Nonatherosclerotic coronary artery disease (NACAD) is a term used to describe a category of diseases, which include: spontaneous coronary artery dissection (SCAD), coronary fibromuscular dysplasia (FMD), ectasia, vasculitis, embolism, vasospasm, or congenital anomaly.

非粥样硬化性冠状动脉疾病（NACAD）是描述一类疾病的术语，包括原发性冠状动脉夹层（SCAD），冠状动脉肌纤维发育不良（FMD），扩张，血管炎，栓塞，血管痉挛或先天性异常。

- NACAD is an important cause of myocardial infarction (MI) in young women, but is often missed on coronary angiography.

NACAD是导致年轻女性心肌梗死的重要原因，但却经常在冠状动脉造影中被忽略。

- A small retrospective study of women <50 years of age with ACS found that 54.8% had normal arteries, 30.5% atherosclerotic heart disease (ACAD), 13% nonatherosclerotic coronary artery disease (NACAD), and 1.7% unclear etiology.

一项针对50岁以下的急性冠脉综合征的女性的小型回顾性研究发现，54.8%的动脉为正常，30.5%为动脉粥样硬化性心脏病，13%为非粥样硬化性冠状动脉疾病，而1.7%病因学不清楚。

- NACAD accounted for 30% of MI’s with SCAD & Takotsubo cardiomyopathy accounting for the majority of cases.

NACAD占心肌梗死的30%，与SCAD及Takotsubo心肌病一起占心肌梗死的大多数。
