Eight patients with office blood pressure >140/90 mmHg, despite being treated with at least three antihypertensive drugs, underwent catheter-based renal denervation. Secondary hypertension was excluded in all patients. Every patient underwent follow-up at 30 days, and then every 3 months. At 6 and 12 months the median value of systolic clinic blood pressure decreased from 161 mmHg (25th-75th percentiles: 158-191 mmHg) at baseline to 144 mmHg (25th-75th percentiles: 136-153 mmHg) at follow up (P=0.012), and the median value of diastolic clinic blood pressure decreased from 102 mmHg (25th-75th percentiles: 94-122 mmHg) at baseline to 90 mmHg (25th-75th percentiles: 78-99 mmHg) at follow-up (P=0.012). The number of medications decreased from 5 (range, 2-8) at baseline to 3.3 (range, 0-6) at follow up. There was a significant decrease of left ventricular mass index from a median of 160 g/m2 (25th-75th percentiles: 147-151 g/m2) at baseline to 126 g/m2 (25th-75th percentiles 107-151 g/m2) at follow-up (P=0.043) was detected. The renal function, and metabolic and neurohumoral parameters, did not change significantly. No complications were observed.

PlumX Metrics

PlumX Metrics  provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
