Revascularization may cause irreversible myocardial injuries About one-third of all elective PCI procedures are associated with significant myocardial injury, which has been linked to increased subsequent mortality.
Beneficial effects of trimetazidine therapy during PCI • Methods • 106 patients with unstable angina pectoris who underwent successful elective PCI • were randomly assigned to standard therapy or trimetazidine treatment • (60-mg loading dose prior to PCI followed by 20 mg tid after PCI on top of standard therapy). • Primary end point, cTnI levels, measured before and at 16-18 hours after PCI. • Secondary end points: • Left ventricular (LV) function evaluated by echocardiography • MACE (death, reinfarction, and target vessel revascularization) XU H et al. Chin J Cardiol. 2013;41(3):205-209.
Beneficial effects of trimetazidine therapy during PCI Results Postprocedural cTnI levels were significantly reduced in the trimetazidine group compared with the control group (P< 0.05). -92% XU H et al. Chin J Cardiol. 2013;41(3):205-209.

Beneficial effects of trimetazidine therapy during PCI Conclusion Trimetazidine can reduce the post-PCI cTnI release and improve LV function after PCI in patients with unstable angina pectoris. Discussion XU H et al. Chin J Cardiol. 2013;41(3):205-209.
Conclusion • About one-third of all elective PCI procedures are associated with significant myocardial injury, which has been linked to increased subsequent mortality. • Trimetazidine can effectively reduce PCI-associated myocardial damage, and has a protective effect on the myocardium. • These benefits could be linked to the mode of action of trimetazidine MR. By providing a 33% increase in cellular energy, trimetazidine MR protects cardiomyocytes against ischemia.
