title: Quality of life improves after renal artery stenting.
abstract: Although treatment of renal artery stenosis (RAS) with stents has been shown to improve blood pressure (BP) and renal function in some patients, little is known about the effect on health-related quality of life. A composite quality of life survey was administered in a cross-sectional cohort fashion to 149 patients presenting with angiographically and hemodynamically confirmed RAS either before (baseline, n = 37) or after (follow-up, n = 112) stent revascularization. BP, renal function, and antihypertensive medication use were also assessed. Systolic BP was lower in the revascularized patients (166 +/- 23 vs. 153 +/- 26, p < .01). The Short Form-36 Physical Component Summary (PCS) scores were higher (better) in revascularized patients (37 +/- 9 vs. 31 +/- 9, p < .01), whereas Mental Component Summary scores were equivalent (49 +/- 13 vs. 51 +/- 11, p = ns). Sleep dysfunction scores were lower (better) in the revascularized patients (32 +/- 26 vs. 48 +/- 32, p < .001), whereas self-reported appetite was higher (better; 62% +/- 29% vs. 73% +/- 27%,p < .05). After matching for age and gender, Short Form-36 PCS remained higher in the revascularized cohort (37 +/- 8 vs. 32 +/- 8, p < .05). Importantly, in multivariate analysis, revascularization was the most significant determinant of a higher PCS score (r2 = .07, beta = 5.21, p < .01). The current data suggest that renal artery stenting may improve health-related quality of life in patients with renovascular disease.
