Observational StudyRenal sympathetic denervation: early impact on ambulatory resistant hypertension.
Although guidelines recommend ambulatory blood pressure (BP) monitoring (ABPM), few data are available regarding the effects of renal denervation (RDN) on 24-hour ABPM values. A total of 44 patients with mean systolic BP ≥135 mm Hg on ABPM despite adequate therapy were included. Basal systolic BP (SBP) and diastolic BP (DBP) were 154±11 mm Hg and 86±12 mm Hg, respectively. ⋯ Neither the number of ablation points nor the amount of impedance drop was predictive of response. Only approximately half of patients with resistant hypertension responded to RDN. However, in these responders, a remarkable reduction of 24-hour BP occurred as early as 1 month after RDN.

Trends in hypertension prevalence, awareness, treatment, and control among US adults 80 years and older, 1988-2010.
The authors examined trends in systolic blood pressure (SBP) and diastolic blood pressure (DBP) and the prevalence, awareness, treatment, and control of hypertension in 1988-1994 (n=1164), 1999-2004 (n=1,026), and 2005-2010 (n=1048) among US adults 80 years and older in serial National Health and Nutrition Examination Surveys. Hypertension was defined as SBP ≥140 mm Hg, DBP ≥90 mm Hg, or use of antihypertensive medication. Awareness and treatment were defined by self-report and control as SBP/DBP<140/90 mm Hg. ⋯ Controlled hypertension increased from 30.4% in 1988-1994 to 53.1% in 2005-2010. The proportion of patients taking 3 classes of antihypertensive medication increased from 7.0% to 30.9% between 1988-1994 and 2005-2010. Increases in awareness, treatment, and control of hypertension and antihypertensive polypharmacy have been observed among very old US adults.
