Abstract:Objective To evaluation of the myoglobin/carbonic anhydraseⅢ(Mb/CAⅢ) ratio and MB isoenzyme of creatine kinase ( CK-MB) as a noninvasive marker in detecting coronary artery reperfusion after thrombolysis. Methods The study consisted of 107 cases of acute myocardial infarction.54 patients received thrombolytic therapy( interventional therapy group, n=54) , 53 patients undergoing coronary angioplasty(thrombolytic therapy group, n=53).The Mb/CA III ratio and CK-MB were measured in the course of treatment.Results Thrombolytic therapy was followed by a (9.1 ± 2.2)fold increase in myoglobin and (10.8 ±3.3)fold increase in CK-MB fraction during the first hour of treatment, while CAⅢremained unchanged.The peak value of Mb/CAⅢratio was found at 2 h and that of CK-MB fraction at 8 h after thrombolysis.The reperfusion time point during primary angioplasty and follow-up of cardiac markers revealed that cut-off points of 3 and 10 h for the peak values of Mb/CAⅢratio and CK-MB fraction can be used as indicators for reperfusion, respectively.Mb/CAⅢratio measured before treatment and 2 and 4 h after the onset of treatment screened 41 of those 45 patients with probable reperfusion after thrombolysis.Conclusion The serum Mb/CAⅢratio can be used to evaluate the rate of infarction reperfusion success in patients with acute myocardial, and to screen the needs for percutaneous transluminal coronary angioplasty.
