This review highlights that approximately 5% of acute myocardial infarctions are caused by nonatherosclerotic mechanisms, such as vasculitis, infections, Kawasaki's disease, metabolic disorders, metastatic disease, and substance abuse.
May prompt consideration of nonatherosclerotic MI etiologies; leaves open need for prospective studies on targeted diagnostics.
Approximately 5% of patients with acute myocardial infarction do not have atherosclerotic coronary artery disease but have other causes for their luminal narrowing. The third part of this three-part review of nonatherosclerotic causes of coronary narrowing focuses on coronary vasculitis, infectious diseases, Kawasaki's disease, metabolic disorders, metastatic disease, and substance abuse (cocaine).
