Streptokinase study on ST segment resolution in patients age less than 40 years with myocardial infarction

ABSTRACT

Thrombolytic therapy for Acute Myocardial Infarction has been one of the most potent treatment ever developed for condition that kill more patients worldwide than any other. To evaluate the benefit and efficacy or observational studies of streptokinase therapy on ST-segment elevation resolution in different types of myocardial infarction that focus especially on the younger age group less than forty years. To observe the streptokinase therapy, in ST-segment elevation resolution, in age less than 40 years and in different types of myocardial infarction. The study was conducted at national institute of cardiovascular diseases [NICVD] of Pakistan, Karachi. All patients fulfilling the inclusion criteria for thrombolytic therapy were included. Baseline ECO recorded before streptokinase infusion and repeated at completion of infusion i.e. 90 minutes, day 1 and day 2. Streptokiriase therapy on blood pressure, CKMB, and ST-segment resolution at 90 minutes, day 1, and Day2 in less than 40-year of age patient. The mean systolic blood pressure was 124 +/- 3.32 and 112 +/- 3.00 pre and post SK therapy reflecting a percentage decrease of 6.67 and highly significant [P<0.001]. The Diastolic blood pressure was decrease to 6.25% with a mean value of 76.80 +/- 2.70 and 72 +/- 1.91 before and after the Streptokinase therapy's, segment resolution at 90 minutes was decreased to 52.01 percent from the baseline and continued to decrease at Day-1 and Day-2 with a percentage reduction of 70.65 and 83.69% respectively. The P values were highly significant [P<0.001]. Thrombolysis improves survival when given within 12 hours of the onset of symptoms. The magnitude of benefit is greatest when reperfusion is established early. Age itself should not be considered a contraindication for fibronolysis
