Abstract: Objective To study the diagnostic and prognostic value of troponin T(cTnT) in patients with unstable angina pectoris(UAP). Methods Totally 98 cases of patients with UAP and 100 cases patients with stable angina pectoris(SAP) were selected, their levels of cTnT were measured respectively at 0-4 hours and 12-24 hours after hospitalization, and the relationship between their cTnT levels and the occurrences of acute heart events within 6 months was observed in follow-up. Results Positive rates of the serum of cTnT in patients with UAP were significantly higher than those in patients with SAP, and those of the serum of cTnT in Braunwald grade 3 were also significantly higher than those in grade 2 and grade 1. The rates of acute heart events in patients with positive cTnT were significantly higher than those with negative cTnT. Conclusion There were an important roles in measuring the serum of cTnT at evaluate the pathogenesis of UAP and its prognostic states.
