High-sensitivity troponinT was negative at 7:58 a.m. (9.2 ng/L). The admission ECG was normal. Symptoms improved after treatment with aeetylic salicylic acid, clopidogrel, and heparin. Coronary CT angiography was performed at 10:30 a.m., demonstrating no evidence of significant stenosis of the main epicardial coronary vessels (Panels A and F). However, the contrast agent filling of the first septal branch discontinued 1 cm after originating from the LAD (Panels A and D), suggesting acute occlusion.
