A case of coronary vasospasm-induced ventricular fibrillation without significant coronary artery disease / 대한내과학회지

ABSTRACT

Coronary vasospasm plays an important role in the pathogenesis not only of variant angina, but also of ischemic heart disease in general, including other forms of angina pectoris, acute myocardial infarction, and sudden death. Vasoactive events leading to an acute reduction in regional myocardial flow in the presence of a normal or previously compromised circulation are a common cause of arrhythmias. However, coronary vasospasm-induced electrical and mechanical complications are rarely reported in patients with angiographically normal or near-normal coronary arteries. This paper presents our experience with a patient presenting with coronary vasospasm-associated ventricular fibrillation without findings of significant coronary artery disease.
