Abstract
OBJECTIVES Ambulatory (ABP) and self-home blood pressure (HBP) measurements are known to be superior to office blood pressure (OBP) measurements in predicting cardiovascular events. Whether ABP has superior prognostic ability than HBP, or the reverse, has not been adequately investigated. METHODS A systematic literature search was conducted to identify outcome studies investigating HBP and ABP in the same population. A meta-analysis was conducted to calculate the pooled measure of risk regarding the primary endpoint of each study for each method. Primary analysis included the comparison of pooled estimates of HBP versus 24 h ABP. RESULTS Among 2587 articles retrieved, 6 fulfilled the inclusion criteria. Meta-analysis of five studies ( n = 4439, weighted age 57 years, men 52%, hypertension 68%, diabetes 15%, cardiovascular disease 11%) indicated pooled hazard ratio per 10 mmHg increase in systolic HBP 1.36 (95% CI 1.23-1.50) and in 24 h ABP 1.38 (1.22-1.57) for the primary endpoint of each study ( z -test P = NS). Meta-analysis of five studies ( n = 4497, weighted age 58 years, men 51%, hypertension 65%, diabetes 15%, cardiovascular disease 9%) indicated pooled hazard ratio per 10 mmHg increase in systolic HBP 1.29 (1.14-1.47), daytime ABP 1.30 (1.15-1.46) and nighttime ABP 1.31 (1.14-1.50) ( z -test, P = NS). Data for DBP were similar. All studies were deemed to have low risk of bias. In studies comparing all the three methods, OBP provided the lowest hazard ratio. CONCLUSION This meta-analysis of the available prospective outcome studies suggested that HBP and ABP have similar ability in predicting outcome and superior to OBP.

Abstract
We stand at a critical juncture in the delivery of health care for hypertension. Blood pressure control rates have stagnated, and traditional health care is failing. Fortunately, hypertension is exceptionally well-suited to remote management, and innovative digital solutions are proliferating. Early strategies arose with the spread of digital medicine, long before the COVID-19 pandemic forced lasting changes to the way medicine is practiced. Highlighting one contemporary example, this review explores salient features of remote management hypertensive programs, including: an automated algorithm to guide clinical decisions, home (as opposed to office) blood pressure measurements, an interdisciplinary care team, and robust information technology and analytics. Dozens of emerging hypertension management solutions are contributing to a highly fragmented and competitive landscape. Beyond viability, profit and scalability are critical. We explore the challenges impeding large-scale acceptance of these programs and conclude with a hopeful look to the future when remote hypertension care will have dramatic impact on global cardiovascular health.

Abstract
OBJECTIVE The prognostic importance of derived central/aortic blood pressures (BPs) in relation to brachial office and ambulatory BPs has never been investigated in patients with resistant hypertension (RHT) or type 2 diabetes (T2D). We aimed to evaluate it in two cohorts with 532 individuals with RHT and 467 with T2D (median follow-ups 4.4 and 7.3 years, respectively). METHODS Central/aortic pressure waveforms were estimated by radial tonometry by a type 1 device (SphygmoCor device/software), and other parameters of central hemodynamics (augmentation index and Buckberg indices) were calculated. Multivariate Cox regressions examined the associations between central and peripheral BPs with cardiovascular events incidence and mortality, and C -statistics and the integrated discrimination improvement index evaluated the improvement in risk discrimination. RESULTS During follow-up, there were 52 cardiovascular events and 51 all-cause deaths in the RHT and 104 and 137 in the T2D cohort. No aortic BP was better than its brachial counterpart in predicting risk or improving discrimination for any outcome in either cohort. In the RHT cohort, ambulatory BPs were superior to central and office-brachial BPs. Otherwise, the augmentation index in RHT (hazard ratios: 1.5, for 1-SD increment) and the Buckberg index in T2D (hazard ratios: 0.7-0.8) were independent predictors of cardiovascular/mortality outcomes, and improved risk discrimination (integrated discrimination improvement up to 25% in RHT and 15% in T2D). CONCLUSION Derived aortic BPs by a type 1 device did not improve cardiovascular/mortality risk prediction over brachial BPs in our cohorts of patients with RHT and T2D, but additional parameters of central hemodynamics may be useful.

Prognostic importance of obstructive sleep apnea and CPAP treatment for cardiovascular and mortality outcomes in patients with resistant hypertension: a prospective cohort study. Hypertens Res 2023; 46:1020-1030. [PMID: 36690808 DOI: 10.1038/s41440-023-01193-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 01/09/2023] [Accepted: 01/10/2023] [Indexed: 01/25/2023]
Abstract
The prognostic importance of obstructive sleep apnea (OSA) severity and other polysomnographic parameters in patients with resistant hypertension (RHT) has never been evaluated. We aimed to assess it in a prospective cohort of 422 individuals with RHT. OSA presence/severity was ascertained by complete polysomnography (PSG) at baseline. Multivariable Cox regressions assessed the risks associated with OSA severity and other PSG parameters (apnea-hypopnea index, sleep duration, nocturnal hypoxemia and periodic limb movements) for the primary (total cardiovascular events [CVEs] and all-cause mortality) and secondary outcomes (major CVEs). In the subgroup of patients with moderate/severe OSA, the risks associated with CPAP treatment were also estimated in relation to untreated individuals. One-hundred and eighty-six participants (44%) had no/mild OSA and 236 (56%) had moderate/severe OSA, and 67 of them were CPAP-treated. Over a mean follow-up of 5 years, there were 46 CVEs (37 major ones) and 44 all-cause deaths. Neither the presence of moderate/severe or severe OSA, nor being untreated during follow-up, was associated with significant excess risks for any outcome in relation to the subgroup with no/mild OSA. Similarly, no other PSG-derived parameter predicted any adverse outcome. Otherwise, CPAP treatment was associated with non-significant risk reductions of 37% for total CVEs, 49% for major CVEs and 63% for all-cause mortality in relation to those who remained untreated during follow-up. In conclusion, the presence/severity of OSA and its related PSG parameters were not associated with worse cardiovascular/mortality prognosis in patients with RHT. However, CPAP treatment might be protective in individuals with moderate/severe OSA.

Abstract
The definition of resistant hypertension (RHT) has been updated to include failure to achieve target blood pressure (BP) despite treatment with ≥3 antihypertensive drugs, including diuretics, renin-angiotensin system blockers, and calcium channel blockers, prescribed at the maximum or maximally tolerated doses, or as success in achieving the target blood pressure but requiring ≥4 drugs. RHT is a major clinical problem, as it is associated with higher mortality and morbidity than non-RHT. Therefore, it is crucial to accurately identify RHT patients to effectively manage their disease. Out-of-clinic BP measurement, including home BP monitoring and ambulatory BP monitoring is gaining prominence for the diagnosis and management of RHT. Home BP monitoring is advantageous as it is feasibly repetitive, inexpensive, widely available, and because of its reproducibility over long periods. In addition, home BP monitoring has crucial advantage of allowing safe titration for the maximum or maximally tolerable dose, and for self-monitoring, thereby improving clinical inertia and nonadherence, and allowing true RHT to be more accurately identified.

Abstract
AimHypertension is among the most prevalent chronic diseases with diverse etiology, affecting over 1 billion people globally. In numerous studies, vitamin C inversely correlated with blood pressure and was suspected to have antihypertensive properties. Currently, there is conflicting evidence regarding the relationship between vitamin C and blood pressure, with most studies being conducted on hypertensive subjects. The principal objective of this project was to investigate the relationship between vitamin C and blood pressure in normotensive adult subjects.MethodsA total of 2,533 individuals aged 20 years and above were enrolled in the present study from the National Health and Nutrition Examination Survey (NHANES) 2017-2018. Outcome variables were systolic blood pressure (SBP) and diastolic blood pressure (DBP). Serum vitamin C was regarded as an independent variable. EmpowerStats software and R (version 3.4.3) were used to examine the association between vitamin C and SBP or DBP.ResultsVitamin C was reversely correlated with both SBP (β = −0.02, 95% CI: −0.03 to −0.00, p = 0.0306) and DBP (β = −0.02, 95% CI: −0.04 to −0.01, p = <0.0011) after adjusting all covariates. This reverse relationship may be affected by a number of factors, including a person’s gender, age, race, and ethnicity. A U-shaped association between vitamin C and SBP in females and an inverted one between vitamin C and DBP in males were detected, respectively. We further calculated the inflection points at 90.3 μmol/L for females and 40 μmol/L for males. It is somewhat surprising that a reverse U-shaped distribution between vitamin C and SBP and DBP in people over 50 was detected, and the point of inflection of vitamin C were all located at 40 μmol/L.ConclusionVitamin C was negatively correlated with both SBP and DBP in this cross-sectional analysis. However, a U-shaped relationship and an inverted one were also observed in certain people, which implied that, though vitamin C is considered a vital antioxidant, maintaining vitamin C at appropriate levels may be beneficial according to different populations.

Abstract
INTRODUCTION Stroke is the second-leading cause of death worldwide and the second-leading cause of disability-adjusted life-years. It is well known that hypertension is a significant risk factor for cardiovascular events, including stroke. AREAS COVERED Recent interventional trials have demonstrated the superiority of intensive blood pressure (BP) control for prevention of cardiovascular events compared to standard BP control. Notably, in the Strategy of Blood Pressure Intervention in Elderly Hypertensive Patients (STEP) trial, intensive BP control showed superiority in the prevention of stroke events in elderly hypertensive patients. Novel medications such as angiotensin receptor-neprilysin inhibitors and sodium glucose cotransporter 2 inhibitors have the potential to suppress various CVD events including stroke. Non-pharmacological antihypertensive therapies such as renal denervation have demonstrated BP-lowering effects and may be useful for stroke prevention. Additionally, new methods and systems of BP monitoring including various kinds of nighttime BP measurement devices, wearable devices, and methods using information and communication technology can be used to assess the pathophysiology of BP variability as a risk factor and an event trigger of stroke incidence. EXPERT OPINION Novel therapies and new technologies for BP evaluation strongly support the development of individualized anticipatory medicine, which should be useful for the prevention of stroke.

Abstract
PURPOSE OF REVIEW As the evidence on different blood pressure phenotypes and their cardiovascular risks evolve, it is imperative to evaluate the reliability of office blood pressure (OBP), ambulatory blood pressure (ABP), and home blood pressure (HBP) measurements and their associations with cardiovascular morbidity and mortality. RECENT FINDINGS HBP is more reliable in diagnosis of hypertension than OBP or ABP. HBP correlates better with left ventricular mass index (LVMI). Increasing systolic HBP is associated with a higher risk of all-cause mortality, cardiovascular mortality, and cardiovascular events. An elevated systolic ABP is also associated with a higher risk of cardiovascular events and mortality. ABP is a better predictor of cardiovascular events than OBP in diabetics. ABP and HBP furnish additional information beyond OBP. They correlate better with cardiovascular outcomes and are more helpful with monitoring therapy than OBP. Comparative effectiveness studies of all three methods associating with cardiovascular outcomes are warranted.
