Myocardial salvage with streptokinase combined with nitroglycerine and verapamil in acute myocardial infarction
1988
Abstract We tested the hypothesis that preservation of left ventricular function results from treatment with intravenous streptokinase given in the first 2 hours from onset of acute transmural myocardial infarction together with nitroglycerine and verapamil. Thirty-three consecutive patients with onset of pain less than 2 hours prior to admission, received intravenous streptokinase 1.5 × 10 6 units with intravenous nitroglycerine and verapamil; 23 concurrently admitted "control" patients with pain onset 2–4 hours received intravenous nitroglycerine and verapamil only. Radionuclide ventriculographic assessment at 2 days revealed a significantly greater left ventricular ejection fraction in the streptokinase-treated patients (54.5 ± 2.8 vs 46.1 ± 2.9; P P We conclude that early presentation and treatment with intravenous streptokinase, nitroglycerine and verapamil is associated with a high incidence of successful thrombolysis and significant preservation of left ventricular function. Nitroglycerine and verapamil may augment the efficacy of streptokinase in this group of patients.
