Objective To evaluate the efficacy of attovastatin in the treatment of patients with heart failure after myocardial infarction, and to provide reliable evidence for evidence-based treatment of those patient. Methods The randomized controlled trial (RCT) were searched from PubMed, Cochrane Library, EMbase, CNKI, Wanfang, VIP and other databases. The time limit for retrieval is from the construction of the database to October 2018. This study was carried out with RevMan 5.3 software to evaluated its clinical efficacy objectively. Results A total of 22 RCTs were included, involving 10 971 patients. The results of Meta-analysis with 20 RCTs showed that:(1) Compared with the routine treatment group, the six-minute walking distance and the left ventricular ejection fraction (LVEF), in attovastatin group was significantly increased[MD=7.56, 95%CI(4.13, 10.98), P<0.0001; MD=20.06, 95%CI(9.77, 30.35), P=0.000 1]. And the N-terminal brain natriuretic peptide (NT-proBNP), brain natriuretic peptide (BNP), left ventricular end-diastolic diameter (LVEDD), the left ventricular end systolic diameter (LVEDS) significantly decreased[MD=-153.23, 95%CI (-186.97, -119.49), P<0.000 01; MD=-96.74, 95%CI (-117.10, -76.38), P<0.000 01; MD=-5.69, 95%CI (-8.11, -3.27), P<0.000 01; MD=-6.80, 95%CI (-8.65, -4.95), P<0.000 01]. (2) Seven of the RCTs involved different doses of attovastatin showed the LVEDD, LVESD, NT-proBNP, BNP of 20 mg groups were significantly lower than those of 40 mg groups[MD=-5.13, 95%CI (-6.05, -4.21), P<0.000 01; MD=-0.84, 95%CI (-1.50, -0.17), P=0.01; MD=-26.53, 95%CI (-47.68, -5.37), P=0.01; MD=-17.63, 95%CI (-32.66, -2.59), P=0.02]; LVEF and six-minute walking distance was markedly increased[MD=9.13, 95%CI (7.95, 10.31), P<0.000 01; MD=22.24, 95%CI (7.06, 37.43), P=0.0004]. The results of qualitative analysis showed that attovastatin could effectively improve the clinical symptoms and cardiac function of patients with heart failure after myocardial infarction. Conclusion attovastatin is effective in the treatment of heart failure patients after myocardial infarction, which can effectively prevent the further development of asymptomatic heart failure. However, these conclusions need to be verified by more large samples and high quality clinical trials.
