PURPOSE: Device-guided slow breathing (DGB) is indicated as nonpharmacological treatment for hypertension. The sympathetic nerve activity (SNA) reduction may be one of the mechanisms involved in blood pressure (BP) decrease. The aim of this study is to evaluate the long-term use of DGB in BP and SNA. SUBJECTS AND METHODS: Hypertensive patients were randomized to listen music (Control Group-CG) or DGB (aim to reduce respiratory rate to less than 10 breaths/minute during 15 minutes/day for 8 weeks)...

BACKGROUND AND AIM: The prevalence and associated risks of white-coat hypertension (WCH) are still a matter of debate. We aimed to assess differences in prevalence and associated conditions of WCH defined on the basis of the normality of all daytime, night-time, and 24-h blood pressure (BP), only daytime, or only 24-h BP. METHODS: We selected 115 708 patients (45 020 untreated and 70 688 treated) from the Spanish Ambulatory BP Monitoring Registry. WCH was estimated in patients with elevated office BP (≥140 and/or 90 mmHg) by using normal daytime (<135/85) BP, normal 24-h BP (<130/80), or normal daytime, night-time (<120/70) and 24-h BP...

In the absence of left ventricular hypertrophy, importance of fragmented QRS complex (fQRS) in individuals with hypertension is unknown. The authors aimed to evaluate the relationship between blood pressure levels and fQRS in the absence of left ventricular hypertrophy. A total of 548 never-treated patients who underwent 24-hour ambulatory blood pressure monitoring were enrolled. The frequency of fQRS was significantly higher in patients with hypertension than normotension (36.4% vs 17.6%, P<.05). Multivariate logistic regression analysis revealed that systolic blood pressure is significantly associated with presence of fQRS on electrocardiography (odds ratio, 0...

PURPOSE: Out-of-office blood pressure (BP) measurements (home blood pressure monitoring [HBPM] and ambulatory blood pressure monitoring [ABPM]) provide important additional information for effective hypertension detection and management decisions. Therefore, out-of-office BP measurement is now recommended by several international guidelines. This study evaluated the practice and uptake of HBPM and ABPM among physicians from Singapore. MATERIALS AND METHODS: A sample of physicians from Singapore was surveyed between 8 September and 5 October 2016...

Hypertension (HTN) is a significant global health problem, responsible for 7.5 million deaths each year worldwide. The prevalence of HTN is increasing in the pediatric population likely attributed to the increase in childhood obesity. Recent work has also shown that blood pressure (BP) tends to track from childhood to adulthood including BP-related target organ damage. In the last 25-30 years, pediatric use of ambulatory blood pressure monitoring (ABPM) has been expanding mainly in the setting of initial elevated BP measurement evaluation, HTN therapy efficacy follow-up, and renal disease...

The brain is a central component of cognitive and physical human performance. Measures including functional brain activation, cerebral perfusion, cerebral oxygenation, evoked electrical responses, and resting hemodynamic and electrical activity are all related to, or can predict health status or performance decrements. However, measuring brain physiology typically requires large, stationary machines that are not suitable for mobile or self-monitoring. Moreover, when individuals are ambulatory, systemic physiological fluctuations-e...

BACKGROUND: Among individuals without hypertension based on clinic blood pressure (BP), it is unclear who should be screened for masked hypertension, defined as having hypertension based on out-of-clinic BP. We hypothesized that individuals with a higher 10-year predicted atherosclerotic cardiovascular disease (ASCVD) risk, calculated using the pooled cohort risk equations, have a higher prevalence of masked hypertension. METHODS AND RESULTS: We analyzed data from the Jackson Heart Study-a population-based cohort of blacks-to determine the association of predicted ASCVD risk with masked hypertension...

Refractory hypertension is a recently described phenotype of antihypertensive treatment failure defined as uncontrolled blood pressure (BP) despite the use of ≥5 different antihypertensive agents, including chlorthalidone and spironolactone. Recent studies indicate that refractory hypertension is uncommon, with a prevalence of ≈5% to 10% of patients referred to a hypertension specialty clinic for uncontrolled hypertension. The prevalence of white coat effect, that is, uncontrolled automated office BP ≥135/85 mm Hg and controlled out-of-office BP <135/85 mm Hg, by awake ambulatory BP monitor in hypertensive patients overall is ≈30% to 40%...

Reverse or inverted dipping (ie, the phenomenon characterized by higher nighttime compared with daytime blood pressure values) is an alteration of circadian blood pressure rhythm frequently documented in hypertension, type 2 diabetes mellitus, chronic kidney disease, and sleep apnea syndrome, and generally regarded as a harmful condition. Available literature on the clinical and prognostic implications of reverse dipping is scanty. The present article will review a number of relevant issues concerning reverse dipping, in particular: (1) its possible mechanisms; (2) prevalence and clinical correlates, (3) concomitant cardiac and extracardiac subclinical organ damage; (4) association with acute and chronic cardiovascular diseases; (5) prognostic value in predicting cardiovascular events and mortality; and (6) therapeutic interventions aimed at reverting this abnormal circadian blood pressure rhythm...

Diabetic retinopathy (DR) is a chronic microvascular complication associated a worse prognosis. We aimed to evaluate the predictors of development/progression of DR in a cohort of 544 high-risk patients with type 2 diabetes who had annual ophthalmologic examinations over a median follow-up of 6 years. Ambulatory blood pressure (BP) monitoring and aortic stiffness by carotid-femoral pulse wave velocity were performed. Multivariate Cox survival analysis examined the independent predictors of development or progression of DR...

BACKGROUND: To date, few studies have analyzed postexercise hypotension (PEH) in hypertensive patients with different levels of physical fitness. AIM: Therefore, this study aimed to compare PEH in trained and sedentary hypertensive individuals. METHODS: Fifty-one well-controlled hypertensive patients of both sexes were assigned to a trained group [60.4±9.4 years; resting blood pressure (BP)=126.3±5.4/75.0±6.3 mmHg; VO2peak=27.3±4.6 ml kg/min] and 58 sedentary hypertensive patients of both sexes were assigned to a sedentary group (63...

Since the use of ambulatory blood pressure monitoring (ABPM) in the beginning of the 70's, our perception of blood pressure based only on office blood pressure has been challenged. Indeed, more specific phenotypes such as white coat hypertension, masked hypertension or different circadian patterns of blood pressure have been described and studied. This has resulted in increased use of ambulatory blood pressure measurements for diagnostic and therapeutic purposes. The main focus of this paper is night-time blood pressure...

Diurnal variations in blood pressure (BP) loss are closely associated with target organ damage and cardiovascular events. The quantity of coronary artery calcification (CAC) correlates with the atherosclerotic plaque burden, and an increased quantity indicates a substantially increased risk of cardiovascular events. This study investigated the nighttime diurnal variation in BP loss associated with CAC in patients with chronic kidney disease (CKD).Of the 1958 participants, we enrolled 722 participants with CKD without a history of acute coronary syndrome or symptomatic coronary artery disease...
