Severe diffuse coronary artery spasm in the early phase of cardiogenic shock

Coronary artery vasospasm rarely appears as a diffuse phenomenon that involves all the coronary tree. We present a clinical case of acute myocardial infarction complicated by ventricular fibrillation and cardiogenic shock. Urgent coronary angiography showed occlusion of proximal Circumflex coronary artery and a TIMI I flow in the left anterior descending artery due to severe, diffuse coronary vasospasm. Patient was successfully treated with intra-aortic balloon pump and intracoronary bolus of nitroglycerin with restoration of flow in left coronary branches and complete resolution of shock.
