Usefulness of Wide Pulse Pressure as a Predictor of Poor Outcome After Renal Artery Angioplasty and Stenting

Renal artery stenosis is a common cause of secondary hypertension and ischemic nephropathy. Percutaneous angioplasty and stent placement has allowed select patients with renal artery stenosis to use fewer antihypertensive agents and improve or stabilize renal function. The associations of baseline systolic, diastolic, and pulse pressures (PPs) with outcomes of blood pressure (BP) and renal function were examined in 243 patients who underwent renal angioplasty and stent placement. The average PP before the procedure in patients with improvements or stabilizations in renal function was 53 ± 20 mm Hg, compared to 107 ± 18 mm Hg (p
