Prevalence and Risk Factors of Renal Artery Stenosis in Patients with Refractory Hypertension / 中国医学影像学杂志

ABSTRACT

PurposeTo investigate the independent risk factors of refractory hypertension for effective screening and treatment.Materials and Methods 142 patients with refractory hypertension underwent renal angiography, morbidity of renal artery stenosis (RAS) and angiography results were analyzed using univariate and multivariate Logistic regression.Results Thirty-eight cases of RAS were identiifed with incidence of 26.8%. Univariate analysis indicated that diabetes, peripheral artery disease and coronary heart disease were the predictor for RAS (P<0.05 orP<0.01). Multivariate regression analysis demonstrated that peripheral artery disease (OR 5.011, 95%CI 2.17-8.93,P<0.001) was independent risk factors for RAS. Diabetes and coronary heart disease were not independent risk factors.Conclusion Peripheral artery disease is independent risk factor for RAS among patients with refractory hypertension, which can serve as a screening index of renal angiography or renal angioplasty and stenting for RAS.
