ABSTRACT
Objective: To explore the effect of trimetazidine (TMZ) on T-peak (Tp) to T-end (Te) interval of resting ECG in patients with unstable angina pectoris (UAP) after percutaneous coronary intervention (PCI). Methods: We investigated 94 UAP patients with PCI and 76 of them ifnished the study as 2 groups. Control group,n=42, the patients received conventional treatment, and TMZ group,n=34, in addition to conventional treatment, the patients received TMZ 60 mg at 0.5 to 1 hour before PCI. The changes of Tp to Te interval before and after PCI were calculated, serum levels of creatine kinase (CK), creatine kinase-MB (CK-MB) and cardiac troponin I (cTnI) at before and at 6, 24 hours after PCI were compared between 2 groups. Ventricular arrhythmia was recorded during PCI. Results: Both groups had shortened Tp to Te intervals after PCI, and TMZ group had more shortened Tp to Te interval, bothP0.05. The occurrence rate of ventricular arrhythmia in Control group was higher than that in TMZ group (12.52% vs 5.16%) during PCI,P<0.05. Compared with Control group, TMZ group had lower levels of CK, CK-MB and cTnI at 6, 24 hours after PCI, allP<0.05. Conclusion: TMZ could decrease Tp to Te interval of resting ECG, prevent ventricular arrhythmia and reduce the relevant myocardial injury in UAP patients after PCI.
