Intracoronary thrombolytic therapy performed within a coronary care unit: one year's experience.

Acute myocardial infarction is associated with a high incidence of occluding coronary arterial thrombi. Thrombolytic therapy has been advocated to restore coronary artery blood flow and to reduce myocardial damage. Coronary arteriography and intracoronary thrombolytic therapy was administered to 61 patients admitted to a Coronary Care Unit within eight hours of symptoms. Successful reperfusion was obtained in 38 of 46 single vessel occlusions associated with a first coronary attack. Failure of reperfusion occurred in patients with two vessel occlusions or with cardiogenic shock. This study demonstrates the feasibility of applying this technique within a Coronary Care Unit with low capital and running costs, and suggests that its widespread application is possible even within the setting of a District General Hospital.
