Objective To evaluate the efficacy and safety of trimetazidine (TMZ) in the treatment of Stable Angina Pectoris (SAP).
Methods Randomized controlled trials (RCTs) on the efficacy and safety of Trimetazidine in treating patients with SAP were retrieved in the following databases as CNKI (1997 to June 2011), WanFang Data (1989 to June 2011), MEDLINE (1966 to June 2011), EMbase (1974 to June 2011), CBM (1989 to June 2011) and Cochrane Central Database (1989 to June 2011). The literature which met the inclusion and exclusion criteria were selected, data were extracted, the quality was evaluated, and meta-analysis was performed by using RevMan 5.0 software.
Results A total of 15 RCTs involving 1 500 patients were included. The meta-analysis showed that, compared with the control group, TMZ was significantly superior in the following 5 aspects: the time to 1 mm drop of ST segment (WMD=0.84, 95%CI 0.74 to 0.93, P=0.000 01), duration of doing exercise (WMD=0.82, 95%CI 0.73 to 0.91, P=0.000 01), and time to onset of angina (WMD=1.18, 95%CI 0.87 to 1.50, P lt;0.000 01) in the treadmill test, weekly mean number of angina attacks (WMD= –1.79, 95%CI –1.93 to –1.66, P lt;0.000 01), and weekly side effects between TMZ and the control group (RR=0.83, 95%CI 0.52 to 1.32, P=0.42).
Conclusion Based on current studies, TMZ is superior to other medicines in the control group for SAP at present, and it has no significant difference in side effects compared with the control group, so it is regarded as an effective and safe drug. For the quality restrictions and possible publication bias of the included studies, this conclusion needs to be confirmed by more high quality, large sample, multi-center, double blind RCTs.
