The Clinical Short-term Outcome of Atorvastatin and Trimetazidine Combination Treatment in Patients with Non-ST Segment Elevation Acute Coronary Syndromes Undergoing Percutaneous Coronary Intervention

Background and Objectives: To investigate the effects of atorvastatin (ATV) and trimetazidine (TMZ) combination treatment in patients with non-ST segment elevation acute coronary syndromes (NSTE-ACS) undergoing percutaneous coronary intervention.

Subjects and Methods: A total of 92 patients with NSTE-ACS were randomly divided into the pretreatment with ATV group (80mg 12h before PCI, with a further 20mg every day to 30th days after PCI, n=44) or the pretreatment with ATV (as the ATV group) and TMZ (60mg 30min before PCI, with a further 20mg tid to 30th days after PCI, n=48). Echocardiography was executed and plasma N-terminal pro brain natriuretic peptide (NT-pro-BNP) levels were measured just prior to the PCI and 30th days after PCI. The main end point was a 30-day incidence of major adverse cardiac events.

Result: Major adverse cardiac events occurred in 9.1% of patients in the ATV group and 4.2% of those in the ATV+TMZ group (P=0.189). NT-pro-BNP of the two groups were decreased 30th days after PCI, however, NT-pro-BNP in the ATV+TMZ group were significantly lower than those in the ATV group (P<0.05). Cardiac function in NSTE-ACS patients, as reflected by the increased LVEF, FS as well as decreased LVEDd (P<0.05) in all groups at 30 days after intervention, but cardiac function parameters were more obviously improved in the group administered with ATV+TMZ (p<0.05).

Conclusion: Short-term pretreatment with the combination of ATV and TMZ administration prior to PCI can prominently decrease NT-pro-BNP and improve cardiac function compared to a single administration of the ATV.
