A history of streptokinase use in acute myocardial infarction

A serendipitous discovery by William Smith Tillett in 1933, followed by many years of work with his student Sol Sherry, laid a sound foundation for the use of streptokinase as a thrombolytic agent in the treatment of acute myocardial infarction. The drug found initial clinical application in combating fibrinous pleural exudates, hemothorax, and tuberculous meningitis. In 1958, Sherry and others started using streptokinase in patients with acute myocardial infarction and changed the focus of treatment from palliation to "cure." Initial trials that used streptokinase infusion produced conflicting results. An innovative approach of intracoronary streptokinase infusion was initiated by Rentrop and colleagues in 1979. Subsequently, larger trials of intracoronary infusion achieved reperfusion rates ranging from 70% to 90%. The need for a meticulously planned and systematically executed randomized multicenter trial was fulfilled by the Gruppo Italiano per la Sperimentazione della Streptochinasi nell'Infarto Miocardico (GISSI) trial in 1986, which not only validated streptokinase as an effective therapeutic method but also established a fixed protocol for its use in acute myocardial infarction. Currently, despite the wide use of tissue plasminogen activator in developed nations, streptokinase remains essential to the management of acute myocardial infarction in developing nations.
