Abstract:
BACKGROUND: Acute myocardial infarction is one of major cardiovascular disease that increases according to the changes of diet and life style. Early diagnosis and treatment of acute myocardial infarction is critical for better prognosis and for reducing mortality. But early diagnosis of acute myocardial infarction is limited by several factors. Recently it was reported that measurements of several serum cardiac enzymes were useful for early diagnosis of acute mocardial infarction. This study was performed to investigate which method of serum creatine kinase measurement is the faster and accurate and whether serum creatine kinase is an early noninvasive predictor of coronary artery patency following thrombolysis in patients with acute myocardial infarction by means of analysis of serial changes in serum creatine kinase. METHODS: This study included 32 patients who had acute myocardial infarction. Serum CK-MB was measured by electrophoretic method and enzymatic immuoasssay method. and compared with EKG and total CK activity which measured by photoabsorbance method. Also we studied whether CK time-activity could be predictor for reperfusion. RESULTS: Immunoassay method accurately measures the serum CK-MB and correlates well with that of electrophoretic method in patients with acute mocardial infarction. Immunoassay method is more sensitive than EKG and has the similar sensitivity to electrophoretic method in diagnosis of acute myoardial infarction. Reperfusion of an occluded coronary artery results in early elevation of serum creatine kinase and CK-MB reflected by earlier appearance time, peak, and onset of clearance. CONCLUSION: Because immunoassay measurement of serum creatine kinase is faster than electrophoresis and requires less technical expertise, it is possible to make diagnosis in patients with acute myocardial infarction in a more timely and cost effective manner and creatine kinase is good predictor of recanalization of an occluded coronary artery after intravenous thrombolytic therapy.
