[The study of the activity of creatine kinase in diagnosis of coronary reperfusion in patients with acute myocardial infarction after thrombolysis].
Early estimation of the efficacy of thrombolysis in acute myocardial infarction is of great clinical importance because the appearance of coronary reperfusion changes therapeutic and diagnostic procedures and decreases the mortality rate. Previous studies showed that the analysis of activity of creatinine kinase (CPK) measured in regular, short periods of time after thrombolysis night be useful in the diagnosis of reperfusion equally to coronary angiography. The aim of the study was to estimate the usefulness of the analysis of creatine kinase (CPK) and its isoenzyme (CK-MB) in the diagnosis of coronary reperfusion in patients with acute myocardial infarction after thrombolytic therapy. The study was performed in 50 patients with acute myocardial infarction admitted to our Cardiology Department, of these 42 were men aged from 34 to 68 and 8 were women aged from 43 to 70. 28 patients had acute inferior myocardial infarction, 22 patients--acute anterior myocardial infarction. All patients were administered 300 mg of aspirin after admission and then 150 mg of aspirin daily and 1,500,000 IU of streptokinase i.v. within 1 hour. Venous blood samples for determination of CPK and CK-MB were obtained every 3 hours during the first 48 h and once a day at 8 a.m from 3rd to 11th day. All patients underwent coronary angiography 2-4 weeks after thrombolysis. The study showed that in patients with reperfusion, activities of CPK and CK-MB three hours after thrombolysis were higher than 30% of later peak. These findings show the usefulness of this criterion in early, non-invasive estimation of efficacy of thrombolysis. Determination of activity of isoenzyme CK-MB during thrombolytic therapy is not necessary, because it evaluates similarly to CPK. We showed that electrocardiographic and enzymatic criteria are comparable in estimation of efficacy of thrombolytic therapy.
