title: Emergency room infusion of intravenous streptokinase in acute myocardial infarction: feasibility, safety, and hemodynamic consequences.
abstract: Between September 1, 1986, and December 31, 1987, sixty-four consecutive patients younger than 70 years, with early (less than 4 hours) symptoms and signs of myocardial infarction, were treated with 1.5 million units streptokinase intravenously in the emergency room (ER group) before admission to the coronary care unit. Data from these patients were compared in retrospect to those of 66 consecutive patients with myocardial infarction who were treated with intravenous streptokinase in the coronary care unit (CCU group) before September 1, 1986. Time between first symptoms and initiation of fibrinolytic therapy was significantly shorter in the ER group: 114 +/- 53 minutes vs 150 +/- 56 minutes in the CCU group (p less than 0.001). The incidence of in-hospital complications was similar in both groups. However, left ventricular stroke work index during the stay in the coronary care unit was 50 +/- 19 gm/m2 in the ER group vs 42 +/- 14 in the CCU group (p = 0.02). Also the echocardiographic left ventricular wall motion score at 48 hours after admission tended to be better in the ER group: 6.7 +/- 4.0 compared to that in the CCU group (7.6 +/- 4.5; p = 0.29). In conclusion, infusion of intravenous streptokinase in the emergency room is feasible and safe and results in a significant time gain leading to a better hemodynamic profile. Within the hospital the emergency room is the ideal place for intravenous fibrinolytic therapy in eligible patients with acute myocardial infarction.
