One year follow-up effect of renal sympathetic denervation in patients with resistant hypertension.

Background: Resistant hypertension is a common clinical problem of blood pressure that is not controlled despite the simultaneous application of multiple antihypertensive agents. Ablation of renal afferent nerves has been applied and proved to decrease hypertension and injuries produced by severe sympathetic hyperactivity. The main objective of this study was to investigate the long-term effect of renal artery sympathetic ablation and its complications in patients with treatment-resistant hypertension.

Atorvastatin and prevention of contrast induced nephropathy following coronary angiography.
