Although percutaneous transluminal coronary angioplasty is successful in more than 90% of patients after acute coronary occlusion, overall mortality remains approximately 10% with higher subgroup mortality (i.e., occlusion of the left anterior descending coronary artery, multivessel disease, age older than 70 years, cardiogenic shock) and early recovery of regional wall motion is marginal. This multicenter report shows that controlled surgical reperfusion in patients with acute coronary occlusion reduces overall and subgroup mortality and restores substantial early contractility. In a survey from six institutions, 156 consecutive patients with acute coronary occlusion documented by angiography underwent surgical revascularization with controlled reperfusion using amino acid-enriched blood cardioplegic solution on total vented bypass. Ventricular wall motion was studied by echocardiography or multiple gated acquisition scan on postoperative days 5 to 7 and scored independently (0 = normal, 1 = mild hypokinesia, 2 = severe hypokinesia, 3 = akinesia, 4 = dyskinesia). Results are compared with results in 1203 patients with acute coronary occlusion treated by angioplasty in five reported medical series. Surgically treated patients were revascularized at longer ischemic intervals (6.3 versus 3.9 hours, p < 0.05) and had a greater incidence of left anterior descending occlusion (61% versus 43%, p < 0.05), multivessel disease (42% versus 22%, p < 0.05), and cardiogenic shock (41% versus 10%, p < 0.05), with 12 patients undergoing cardiopulmonary resuscitation en route to the operating room. Surgical results were superior in all categories, with overall mortality reduced from 8.7% after angioplasty to 3.9% after coronary bypass (p < 0.05). All surgical deaths occurred in patients with preoperative cardiogenic shock. Regional wall motion recovered significantly (score < 2) in 131 of 150 (87%) surgically treated patients with an average score of 0.9 +/- 0.8 (normal to mild hypokinesia) despite longer ischemic times.
