The Observation Of Serum Troponin Ⅰ In Patients With Unstable Angina Pectoris

Objective: To valuate the clinical significance of serum troponin I (CTnI) in patients with unstable angina pectoris and minor myocardial damage (MMD).Methods: Diplo-antibody immunofluorescence was used to detect serum CTnI in 31 healthy subjects,20 stable angina pectoris (SAP) and 36 unstable angina pectoris (SAP) patients.Results: The positive rate of CTnI in UAP (36.11%) was significantly higher than in SAP (5%) and in 31 healthy subjects. Among the 36 UAP patients, the short-term cardiac events were significantly higher in CTnI positive group than in CTnI negative group. No significant difference was found in serum CK-MB among 3 groups.Conclusion: Serum CTnI demonstrates minor myocardial damage and can predict the prognosis of patients with unstable angina pectoris.
