: Myocardial infarction (MI) is the most frequent cause of ischemic heart death. MI is generally assumed to be due to arterial thrombosis superimposed on an atherosclerotic plaque in an epicardial coronary artery. Total occlusion of an epicardial coronary artery leads to ST elevation, while non-occlusive lesion leads to ST depression. We hereby have reported a case of ST-segment elevation myocardial infarction with normal coronary arteries angiography. A 35-year-old man presented with typical chest pain, nausea, vomiting and cold sweating. ECG obtained at admission and 30 minutes later revealed sinus tachycardia with ST-segment elevations (> 2 mm) in leads V2-V5. Cardiac biomarkers including creatine phosphokinase (CPK), creatine kinase muscle-brain (CK.MB) and troponin high sensitive were elevated. The standard treatment for MI including pain relief, aspirin, thrombolysis if indicated and beta blockade were begun for the patient. STEMI was confirmed and thus, angiography was performed. Coronary angiography revealed normal coronary arteries without any angiographic evidence of stenosis, coronary artery dissection, embolism, plaque rupture or vasospasm.

Simultaneous ST-segment elevation (SST-SE) in anterior and inferior leads in the setting of ST-segment elevation myocardial infarction is often confounding for a cardiologist and further more challenging is the angiographic localization of the culprit vessel. SST-SE can be fatal as it jeopardizes simultaneously a larger area of myocardium. This phenomenon could be due to “one lesion, one artery,” “two lesions, one artery,” “two lesions, two arteries,” or combinations in two different coronary arteries. We have discussed an index case where we encountered a phenomenon of SST-SE and coronary angiography demonstrated “two lesions, one artery” (proximal occlusion and distal critical diffuse stenoses of the wrap-around left anterior descending [LAD] artery) and “two lesions, two (different coronary) arteries” (previously mentioned stenoses of the LAD artery and critical stenosis of the posterolateral branch of the right coronary arteries). We have also described in brief the possible causes of this phenomena and their electroangiographic correlation of the culprit vessels.
