Acetylcholine-induced coronary microvascular vasospasm in a patient with angina pectoris and normal coronary angiogram--a case report

We demonstrated a continuous intracoronary infusion of acetylcholine-induced marked decrease of coronary blood flow estimated by intracoronary Doppler flow wire without significant epicardial coronary narrowing. This case can be called a patient with microvascular vasospastic angina.
