Obstructive coronary disease. A 59-year-old man presenting after a prolonged episode of crushing chest pain with bilateral radiation to the arms that subsided after sublingual nitroglycerine. There were non-specific STT-segment changes on the electrocardiogram and normal initial myocardial necrosis markers. Coronary CTA (A–C) shows atherosclerotic plaque (arrowheads) and a short, severe stenosis in the mid-LAD (arrow). Second cardiac markers were positive. Catheter angiography (D and E) confirmed a stenosis in the mid-LAD.
