Intracoronary thrombolysis and early bypass surgery for acute myocardial infarct: five years' experience.

During the five-year period between March 1980 and February 1985 selective intracoronary thrombolysis with streptokinase was performed in 469 patients with clinical and ECG signs of acute transmural myocardial infarct. Coronary arteriography prior to thrombolysis showed the infarct related vessel still or again patent in 21% of the patients. Among 372 patients with complete occlusion streptokinase infusion was successful in 87%, but failed in 13%.
