Renal vein renin analysis: Limitations of its use in predicting benefit from percutaneous angioplasty

摘要: Two hundred forty-four consecutive patients (mean age 61 years), including 123 who had technically valid renal vein renin (RVR) analysis and 121 without RVR data, underwent successful percutaneous artery angioplasty (PTRA). They were retrospectively examined to evaluate the utility of in identifying hypertension (RVH), predicting benefit from PTRA, determining if lack knowledge levels significantly affected clinical outcome after PTRA. Abnormal values associated with PTRA 62 93 (67% sensitivity, 20% specificity, 72% positive predictive value). Clinical improvement following occurred 31 37 normal pre-PTRA (16% negative correctly identified 86 117 renovascular (74% 16% Improved blood pressure (BP) control abnormal 66% data (p>0.1). We conclude that very low value limited use this elderly 60 years) patient population a high incidence mild functional impairment serum creatinine 1.4 mg/dl) bilateral stenosis (38%).
