摘要：Since the evidence regarding statin therapy in PAH has not been conclusive, we assessed the impact of statin therapy in PAH through a systematic review and meta-analysis of available studies. We searched selected databases up to August 1, 2015 to identify the studies investigating the effect of statin administration on PAH. Meta-analysis was performed using either a fixed-effects or random-effect model according to I(2) statistic. Meta-analysis of 8 studies with 665 patients did not suggest any significant improvement in 6-min walking distance (6MWD) by statin therapy (weighed mean difference [WMD]: -6.08 m, 95% confidence interval [CI]: -25.66, 13.50, p = 0.543; Q = 8.41, I(2) = 28.64%). Likewise, none of the other indices including pulmonary arterial pressure (WMD: -0.97 mmHg, 95%CI: -4.39, 2.44, p = 0.577; Q = 14.64, I(2) = 79.51%), right atrial pressure (WMD: 1.01 mmHg, 95%CI: -0.93, 2.96, p = 0.307; Q = 44.88, I(2) = 95.54%), cardiac index (WMD: 0.05 L/min/m(2), 95%CI: -0.05, 0.15, p = 0.323; Q = 3.82, I(2) = 21.42%), and pulmonary vascular resistance (WMD: -1.42 dyn*s/cm(5), 95%CI: -72.11, 69.27, p = 0.969; Q = 0.69, I(2) = 0%) was significantly altered by statin therapy. In conclusion, the results of the meta-analysis did not show a statistically significant effect of statin therapy in the improvement of 6MWD, pulmonary arterial pressure, right atrial pressure, cardiac index and pulmonary vascular resistance.
