Effect of the Injection Speed of Streptokinase in Patients with Acute MI Admitted to the Cardiac Intensive Care Section of Imam Khomeiny Hospital in Ardabil 2011-2012
Abstract
Background & objectives: Myocardial infarction (MI) isone of the most commonly heart diseases in all countries with the mortality rate of about 30%. Reperfusion of blocked coronary arteries plays an important role in reducing mortality and enhancing the quality of life of patients after acute MI. Methods: This clinical trial is to compare the efficacy of streptokinase administered intravenously in a two slow and accelerated groups: control group (slow intravenous infusion during 1 hour) and case group (half-hour accelerated intravenous infusion of streptokinase) with the sample size of 100 patients (divided randomly to 50 patients in each group). The data tool was a questionnaire, included the collected ECG changes before and after echocardiography and laboratory tests of patients. Data analyzed with SPSS software using chi-square test. Results:After reperfusion of the coronary artery, in the both case and control groups, elevation of ST segment has decreased statistically in two groups (60% and 84%, respectively). The complications rate following injection of SK in both case and control groups were 46% and 56%, respectively. The fraction in which 30% and 38% belong to cardiac complications, 32% and 22% to allergic symptoms and hematologic effects were 32% and 22%, in two groups, respectively and there was no statistically significant difference between two groups. Conclusion:According to the results of this study the accelerated (30 minutes) SK infusion can be fruitful for improving coronary reperfusion in patients with MI.
