OBJECTIVE: Adherence to antihypertensive medications is often less than optimal. Research suggests that patients have limited confidence regarding whether office blood pressure (BP) assessments represent their 'true' BP, which may further promote poor adherence to BP-lowering medication. We assessed peoples' confidence in the methods of BP assessment and examined the associations between patients' confidence levels and medication adherence comparing office and home BP-monitoring techniques...

BACKGROUND: The different geometric patterns of the left ventricle may or may not coexist with chamber dilatation. The prognostic impact of such a combination is unclear. METHODS AND RESULTS: We studied a cohort of 2635 initially untreated patients with hypertension, mean age 50 years. At entry, 24-hour ambulatory blood pressure progressively increased across the patterns of normal geometry, concentric left ventricular (LV) remodeling, eccentric nondilated LV hypertrophy (LVH), eccentric dilated LVH, concentric nondilated LVH, and concentric dilated LVH...

INTRODUCTION: Ambulatory blood pressure monitoring by automatic device is the best blood pressure evaluation method and sleep apnea syndrome is the leading cause of poor control. Oximetry allows screening these individuals but its usefulness has been poorly explored in Primary Health Care. The aim was to evaluate the blood pressure control at the office and with ambulatory blood pressure monitoring by automatic device and to relate it to sleep apnea syndrome. MATERIAL AND METHODS: We selected a sample of 50 participants, representative of 3036 hypertensive patients...

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a novel class of antihyperglycemic agents that improve glycemic control by increasing glycosuria. Additional benefits beyond glucose lowering include significant improvements in seated clinic blood pressure (BP), partly attributed to their diuretic-like actions. Less known are the effects of this class on 24-hour ambulatory BP, which is a better predictor of cardiovascular risk than seated clinic BP. METHODS AND RESULTS: We performed a meta-analysis of randomized, double-blind, placebo-controlled trials to investigate the effects of SGLT2 inhibitors on 24-hour ambulatory BP...

Study Objectives: Sudden unexpected death during sleep (SUDS) is the most common cause of death in patients with familial dysautonomia, an autosomal recessive disease characterized by sensory and autonomic dysfunction. It remains unknown what causes SUDS in these patients and who is at highest risk. We tested the hypothesis that SUDS in FD is linked to sleep-disordered breathing. Methods: We retrospectively identified patients with familial dysautonomia who died suddenly and unexpectedly during sleep and had undergone polysomnography within the 18-month period prior to death...

OBJECTIVE: Accumulation of reactive oxygen species by increased uric acid production has been suggested as a possible underlying mechanism for the association between uric acid and high blood pressure (BP). We, therefore, investigated the association between serum uric acid concentration 24-h urinary uric acid excretion, as proxy for uric acid production, and ambulatory 24-h BP and hypertension. METHODS: Cross-sectional analyses were conducted among 2555 individuals [52% men, mean age 60...

BACKGROUND: Renal sympathetic denervation seems to be less effective as a treatment for hypertension in patients with isolated systolic hypertension, a condition associated with elevated central arterial stiffness. Because isolated systolic hypertension can also be caused by wave reflection or increased cardiac output, a more differentiated approach might improve patient preselection for renal sympathetic denervation. We sought to evaluate the additional predictive value of invasive pulse wave velocity for response to renal sympathetic denervation in patients with combined versus isolated systolic hypertension...

Hypertension after kidney transplant is a frequent occurrence in pediatric patients. It is a risk factor for graft loss and contributes to the significant burden of cardiovascular disease (CVD) in this population. The etiology of posttransplant hypertension is multifactorial including donor factors, recipient factors, medications, and lifestyle factors similar to those prevalent in the general population. Ambulatory blood pressure monitoring has emerged as the most reliable method for measuring hypertension in pediatric transplant recipients, and many consider it to be essential in the care of these patients...

OBJECTIVE: Renal denervation (RDN) can cause focal (notches) and global (spasms) changes in renal artery dimensions. We quantified these changes and related them to renal norepinephrin tissue content in animals and to blood pressure (BP) changes in patients. METHODS: We measured renal artery dimensions pre-RDN and post-RDN, utilizing quantitative renal angiography (QRA) in a porcine model and in a retrospective patient cohort, and intravascular ultrasound (IVUS) in a prospective patient cohort...
