Use of tissue plasminogen activator in the coronary care unit for acute closure after coronary angioplasty.

Coronary angioplasty in a patient ten days following myocardial infarction was complicated by repeated thrombotic occlusion requiring intracoronary streptokinase. Recurrence of chest pain and ST elevations after transfer to the coronary care unit was successfully managed with intravenous tissue plasminogen activator without returning the patient to the catheterization laboratory.
