Evolution of MI

1 comment:

  1. Q: A 67-year-old man with a history of hyperlipidemia, hypertension, and angina presents to the emergency department with crushing substernal chest pain radiating down his left arm. The pain is not relieved by rest or sublingual nitroglycerin. ECG reveals ST-segment elevation in the V1-V4 with ST-segment depression in leads III and aVL. Cardiac biomarkers are elevated. The patient is taken for emergent cardiac catheterization and percutaneous coronary intervention of an occluded left anterior descending artery. He leaves the catheter laboratory symptom free. After this patient is revascularized, at what point in time is he most likely to develop diffuse ST-segment elevations in all leads, pleuritic chest pain, and a friction rub?

    A: 5-10 days
