Levels of CK-MB and Troponin I in Patients who Underwent Percutaneous Transluminal Coronary Angioplasty

Aim: Not only the progressive increase in indications for percutaneous transluminal coronary angioplasty (PTCA) attracts the attention, but also the myocardial damage that may develop after this technique. In this paper, the significance of cardiac markers in detecting myocardial damage following PTCA is discussed. Methods: 47 randomly selected patients, who have undergone PTCA procedure for different reasons, had blood analysis of cTnI and CK-MB levels before and after the procedure between 6 and 12 hours. Chemiluminescent Enzyme Immunoassay method was applied for cTnI and kinetic immunoinhibition method was applied for CK-MB. Results: Significant increase was found in levels of cTnI (p
