Insights on safety and efficacy of renal artery denervation for uncontrolled-resistant hypertension in a high risk population with chronic kidney disease: first Italian real-world experience.

Aims: To evaluate the safety and efficacy of catheter-based radiofrequency renal sympathetic denervation (RSD) in a daily practice population of patients with uncontrolled resistant hypertension, on top of medical therapy.

Methods: Consecutive unselected patients with uncontrolled resistant hypertension undergoing RSD were enrolled. Office and ambulatory blood pressure (BP) measurements were collected at baseline and 3, 6 and 12 months after RSD.

Long-Term (3 Years) Prognosis of Contrast-Induced Acute Kidney Injury After Coronary Angiography.

Contrast-induced acute kidney injury (CI-AKI) after coronary angiography or interventions is relatively frequent and portends adverse outcomes. The lack of a "universally accepted" definition, however, limits the integration and comparison of available data. We aimed to detect the CI-AKI definition that best correlates with the occurrence of clinical events at long-term in a 3-year follow-up study of patients at intermediate-to-high risk for CI-AKI.
