| Summary: | To provide definite evidence for the anti-hypertensive benefit of Baroreflex Activation Therapy (BAT) for resistant hypertension, we performed a systematic review and meta-analysis to evaluate the efficacy and safety of BAT. Electronic searches were conducted in PubMed, EMBASE, The Cochrane Library and Web of Science. Two reviewers independently determined the eligibility of studies and extracted the data. The quality of all included studies was evaluated by the use of the Newcastle Ottawa Scale (NOS). Disagreements were settled through discussion. Twelve studies, included one randomized clinical trials (RCTs) and eleven prospective studies were eligible for qualitative analysis and five prospective studies were selected for meta-analysis. The data of analysis showed office systolic blood pressure (SBP)(WMD = −24.01, 95% CI = −28.65 to −19.36, P= 0.753I2 = 0.0%) and diastolic blood pressure (DBP)(WMD = −12.53, 95% CI = −15.82 to −9.24,P = 0.893,I2 = 0.893) decreased by BAT treatment.The effect on SBP was both significant in the Barostim neo TM device (WMD = −22.49, 95% CI = −29.13 to 15.84, P= 0.443; I2 = 0.0%) and Rheos System (WMD = 25.46, 95% CI = −31.96 to −18.96, P= 0.703; I2 = 0.0%). Our study found office BP were significantly decreased by BAT treatment, but available evidence is limited by risk of bias, small sample size, and few RCTs. Thus, there is presently insufficient evidence to fully evaluate the efficacy and safety of BAT for Patients with Resistant Hypertension. Additional high-quality RCT research with long-term follow-up is required. |
