A Case of Rest Angina due to Microvascular Spasm

概要

論文の詳細を見る
A 66-year-old woman underwent elective cardiac catheterization for investigation of periodic attacks of chest pain at rest. During the examination, a chest pain attack occurred unexpectedly, resulting in ST elevation in the precordial leads on electrocardiography. Immediate coronary arteriography demonstrated no organic stenosis but markedly delayed contrast medium perfusion in the mid to distal portion of the left anterior descending artery. These phenomena spontaneously disappeared about 3 min later, and the patient was diagnosed as having angina pectoris due to microvascular spasm. The demonstration of angina pectoris due to microvascular spasm by coronary arteriography during a spontaneous attack is very rare.
