The prognostic value of serum cardiac troponin Ⅰ in unstable angina pectoris / 心血管康复医学杂志

ABSTRACT

Objective: To evaluate the prognostic value of serum troponin Ⅰ (cTnI) in unstable angina pectoris (UA). Methods: Serum cTnI, creatine kinase isoenzyme MB (CK－MB) were simultaneously measured in 25 healthy subjects, 96 UA patients, routine treatment was administered and cardiac events were observed closely within two weeks. Results: Thirteen of 28 UA patients whose cTnI was≥0.3μg/L developed cardiac events, only 3 of 68 UA patients whose cTnI was ＜0. 3 μg/L developed cardiac events within two weeks, there was a significant difference (P＜0. 05). Conclusion: There is a clinical value of serum cTnI measurement in identifying the high risk patients of UA. The patients whose cTnI was≥0. 3μg/L indicate a poor prognosis.
