Objectives To systematically assess the efficacy and safety of nitrates for patients with chronic heart failure. Method We searched PubMed, EMbase, Web of Science, The Cochrane Library (Issue 1, 2016), CBM, CNKI, VIP, and WanFang Data to collect randomized controlled trials (RCTs) and cross-over studies about nitrates in the treatment of heart failure from inception to January 4th 2016. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software. Results Ten trials were included involving 414 patients (195 patients in the nitrates group and 219 patients in the control group). The results of meta-analysis showed that, compared with the control group, the nitrates group could reduce arterial blood pressure (MD=-1.91, 95%CI -3.66 to -0.16, P=0.03), pulmonary wedge pressure vessels (PCWP) (MD=-2.00, 95%CI -3.84 to -0.15, P=0.03), increase cardiac index (CI) (MD=0.25, 95%CI 0.09 to 0.42, P=0.003), treadmill exercise time (MD=70.14, 95%CI 55.22 to 85.05, P < 0.000 01); but easily emerge side effects (OR=5.21, 95%CI 2.60 to 10.41, P < 0.000 01). Conclusion Current evidence indicates that nitrates treatment could improve the hemodynamic effect, enhance cardiac output and increase exercise tolerance in patients with heart failure.
