CORONARY FLOW RESERVE IN PATIENTS WITH PRIOR SPONTANEOUS CORONARY ARTERY DISSECTION AND RECURRENT ANGINA

摘要

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an important cause of myocardial infarction (MI) in young women. A significant proportion of SCAD patients have ongoing chronic chest pain despite healing of their dissection, the etiology of which is poorly understood. We sought to determine whether coronary microvascular dysfunction (CMD) contributes to post-SCAD chronic chest pain by performing coronary reactivity testing (CRT) in the cardiac catheterization laboratory.
