Abstract:
Objectives:To investigate long-term clinical outcomes of renal denervation(RDN)for the treatment of resistant hypertension. Methods:This study retrospectively enrolled 58 patients with resistant hypertension who received RDN treatment via femoral artery approach at Fuwai Hospital between February 2012 and November 2019.Follow up was performed at 1,3,6 months,1 year,and annually after RDN,and the last follow-up was June 2023.The baseline data and postoperative follow-up data including office blood pressure,24-hour mean blood pressure and heart rate,types and load of antihypertensive drugs,renal function,and major adverse events(including renal artery stenosis,acute myocardial infarction,stroke,cardiovascular death,and all-cause death)were obtained and analyzed.The impact of RDN on 10-year cardiovascular and cerebrovascular events was evaluated using the Framingham risk assessment model and the Chinese model. Results:A total of 58 patients were enrolled,with 1 patient(1.72%)died from lung cancer.Forty-one patients(70.69%)were visited in the last follow-up and the average follow-up time was(10.21±1.75)years.Compared with baseline,the office systolic/diastolic blood pressure was decreased by(12.59±21.65)/(9.87±14.27)mmHg(P<0.01,1 mmHg=0.133 kPa),24-hour mean systolic/diastolic blood pressure reduced by(11.28±15.33)/(7.94±12.29)mmHg(P<0.01),24-hour mean heart rate reduced by(2.45±9.46)bpm(P>0.05),the types of antihypertensive drugs decreased by 1.17±2.25(P<0.01),the drug load reduced by 1.45±2.37(P<0.001),and the estimated glomerular filtration rate decreased by(6.83±18.37)ml/(min·1.73 m2)(P<0.05)at the last follow-up.The impact of RDN on 10-year cardiovascular events and stroke risk was as follows:Framingham risk assessment showed an absolute risk decrease of 14.25%and 2.12%,respectively,and decreased by 5.72%and 17.46%using the Chinese cardiovascular and cerebrovascular risk assessment. Conclusions:This study showed that RDN could significantly reduce blood pressure levels in patients with resistant hypertension in the long-term follow up,and was expected to further reduce cardiovascular and cerebrovascular risks.
