Abstract:
Objective To investigate cardiac troponin I (cTnⅠ) for detecting minor myocardial damage and evaluating the prognostic value in unstable angina (UA) Methods Serum cTnⅠ, creatine kinase isoenzyme MB (CK MB) and a part in cardiac troponin T (cTnT) were measured in 106 (UA) and 44 stable angina (SA) patients as well as 68 cases with normal coronary angiography, 72 healthy subjects Relative risk factors and occurrence of heart events were analyzed Results 61 of 106 patients with UA had elevated cTnⅠ levels (57 5%), but 8 of 44 cases with SA had positive results (18 18%) Among them, only 3 cases had slightly elevated CK MB levels The incidences of heart events were significantly higher in patients with elevated cTnⅠ levels than in patients with normal one The higher cTnⅠ levels was and the more heart events occurred cTnT values was similarly found to be an indicator of increased risk of heart events Conclusion cTnⅠ is a higher sensitive and specific marker for assessing minor myocardial damage cTnⅠ is a strong independent indicator of risk stratification in UA
