摘要：
Pulmonary hypertension (pH) is a progressive and fatal disease with poor long-term prognosis and high mortality. Although great progress has been made in current treatment methods, the survival rate is still poor. Therefore, we need to find an effective treatment for pH.pH is a type of refractory, progressive, and fatal pulmonary vascular disease which involves a variety of clinical conditions and may complicate most cardiovascular and respiratory diseases. Pulmonary artery denervation (PADN) therapy for pH has become the current trend, but its clinical application still faces a series of problems, and its efficacy remains controversial. The purpose of the study is to evaluate the literature on the effects of PADN for pH.The PubMed, Embase, and Web of Science databases were searched by two researchers until April 9th, 2021. The literature was read and screened, and effective data(6-minute walking distance, cardiac output, mPAP, PVR,Left ventricular end-systolic diameter,Cardiac output,Readmission rate,Mortality,Cardiac function,and so on) was extracted, collated, and analyzed. The literature was managed by Endnote 9.3 software and evaluated by RevMan 5.3 software.The meta-analysis included five controlled experiments with a total of 339 patients. The literature quality evaluations were all Level B. The meta-analysis results showed that compared with the control group, PADN treatment could improve the 6-minute walking distance of pH patients [WMD = 103.72, 95%CI (49.63, 157.82), P < 0.05], reduce mean pulmonary artery pressure (mPAP) [WMD = -7.26, 95%CI (-10.86, -3.66), P < 0.05], reduce pulmonary vascular resistance (PVR) [WMD = -4.53, 95%CI (-8.23, -0.83), P < 0.05], and improve cardiac output [WMD = 0.48, 95%CI (0.23, 0.73), P < 0.05]. There was no significant effect on the left ventricular end-systolic diameter [WMD = -0.13, 95%CI (-0.49, 0.24), P > 0.05], readmission rate [OR = 0.14, 95%CI (0.01, 1.87), P > 0.05], mortality rate [OR = 0.77, 95%CI (0.22, 2.69), P > 0.05], or cardiac function [OR = 0.32, 95%CI (0.05, 2.10), P > 0.05].PADN is an effective method for the treatment of pH which is worthy of clinical promotion.Copyright © 2022 Elsevier Inc.
