title: Early operative intervention after thrombolytic therapy for acute myocardial infarction.
abstract: Thrombolytic therapy effectively interrupts acute myocardial infarction but does not correct the underlying plaque causing acute thrombosis. Early operation and treatment of the residual coronary artery disease has therefore been evaluated. Over 29 months, 184 patients with acute myocardial infarction of less than 6 hours duration were treated with intracoronary (IC) or intravenous (IV) streptokinase (SK). Angiography was performed early and thrombolysis found to be successful in 70% of the IC-SK group and 82% of the IV-SK group. One hundred six patients with successful thrombolysis had early revascularization surgery performed 3.3 +/- 2.1 days following SK treatment (range 0 to 11 days). These patients were compared with 110 consecutive patients who underwent coronary artery bypass grafting for standard indications. The SK group had an average of 3.0 +/- 1.4 grafts, 4.3 +/- 3.1 units of blood, and 10.8 +/- 5.3 days in the hospital postoperatively per patient and had an operative mortality rate of 2.7%. The control group averaged 3.6 +/- 1.3 grafts, 4.0 +/- 2.4 units of blood, and 9.6 +/- 3.5 days in the hospital postoperatively per patient with an operative mortality rate of 2.7%. This experience indicates that early operation following SK therapy can be performed with low operative risk and without prolonged hospitalization.
