[Laboratory diagnosis of myocardial microlesions during coronary balloon angioplasty with stenting]
Abstract:
Fifty patients with stable angina who had undergone elective coronary angioplasty with stenting were examined. Myocardial microlesions diagnosed from the elevated levels of troponin (Tn) I and creatine phosphate kinase MB (CPK-MB) were detected in 48-54% of the patients; however, the content of Tn I exceeded the high reference level only in 18%. Tn I is a more specific method than CPK-MB in detecting myocardial microlesions during intracoronary intervention. The signs of myocardial microlesions were most commonly detected during intervention into the arteries with types B and C stenoses in case of complicated or technically difficult stent implantation.
