Intracoronary streptokinase therapy in the coronary care unit for acute myocardial infarction

Abstract

Intracoronary streptokinase was offered and preliminary coronary angiography performed in 14 patients who were seen with the clinical diagnosis of acute myocardial infarction within 4 h of onset of symptoms. The procedure was performed in the Coronary Care Unit (CCU) of St. Peter's Medical Center with the use of a portable C‐arm fluoroscope. Angiography was recorded on video tape. Service was provided by an “on‐call” team consisting of two physicians, a CCU nurse, and a radiology technician, on a 24‐h service basis. Adequate visualization of coronary anatomy was obtained in all patients. Patency of occluded vessels was achieved in 10 of 11 patients who received intracoronary streptokinase. The initial streptokinase bolus was administered at a mean interval of 4.1 h from onset of symptoms. It is concluded that speedy and effective coronary thrombolytic therapy can be provided in the CCU on a 24‐h service basis by an on‐call team. The use of CCU for this purpose will make this therapy widely available across the country, without the need for Cardiac Catheterization Laboratory. Copyright © 1984 Wiley Periodicals, Inc.
