BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the impact of treatment with oral trimetazidine (TMZ) applied before and after percutaneous coronary interventions (PCI) on short-term left ventricular functions and plasma brain natriuretic peptide (BNP) levels in patients with non-ST segment elevation myocardial infarction (NSTEMI) undergoing PCI. SUBJECTS AND METHODS: The study included 45 patients who were undergoing PCI with the diagnosis of NSTEMI. The patients were randomized into two groups. The first group (n=22) of the patients hospitalized with the diagnosis of NSTEMI was given conventional therapy plus 60 mg TMZ just prior to PCI. Treatment with TMZ was continued for one month after the procedure. TMZ treatment was not given to the second group (n=23). Echocardiography images were recorded and plasma BNP levels were measured just prior to the PCI and on the 1st and 30th days after PCI. RESULTS: The myocardial performance index (MPI) was greater in the second group (p=0.02). In the comparison of BNP levels, they significantly decreased in both of the groups during the 30-day follow-up period (29.0+/-8 and 50.6+/-33, p<0.01 respectively). However, decreasing of BNP levels was higher in the group administered with TMZ. The decrease of left ventriclular end-diastolic volume was observed in all groups at 30 days after intervention, but was higher in the group administered with TMZ (p=0.01). CONCLUSION: Trimetazidine treatment commencing prior to PCI and continued after PCI in patients with NSTEMI provides improvements in MPI, left ventricular end diastolic volume and a decrease in BNP levels.
