Emergency Coronary-Artery Angioplasty for Cardiogenic Shock Complicating Acute Myocardial Infarction

Figure 1. Emergency Coronary-Artery Angioplasty for Cardiogenic Shock Complicating Acute Myocardial Infarction. Coronary-artery angioplasty was performed in a 45-year-old man who presented with two hours of crushing retrosternal chest pain and hypotension (blood pressure, 90/60 mm Hg). Electrocardiography revealed evidence of an acute anterior-wall myocardial infarction. Coronary arteriography (Panel A) showed a left anterior descending artery that was totally occluded in its proximal portion (indicated by the arrow in each panel), with normal right and circumflex coronary arteries. Emergency coronary-artery angioplasty (Panel B) resulted in rapid antegrade flow without residual stenosis at the site of the occlusion (Panel C). The . . .
