A). 5000 units of conventional heparin were administered by the intravenous route and 600 mg clopidogrel and 300 mg acetylsalicylic acid were given orally. She was taken to the emergency catheterization room. Diagnostic angiography showed diffuse coronary artery disease of the right coronary artery (RCA) (Figure 2 A), approximately 90% stenosis at the ostium of the left circumflex artery (LCX) and 85% stenosis at the ostium of the left anterior descending artery (LAD) (Figure 2 B). After intracoronary administration of 500 g of nitroglycerin, critical stenoses at the ostia of the LCX and LAD disappeared (Figure 2 C), the patient's chest pain resolved and ST segment elevations in leads DII, DIII, aVF and precordial leads and reciprocal findings on ECG returned to baseline (Figure 1 B).
