Metabolism 2024; 154:155831. [PMID: 38431129 DOI: 10.1016/j.metabol.2024.155831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 02/22/2024] [Accepted: 02/27/2024] [Indexed: 03/05/2024]
Abstract
BACKGROUND Excessive dietary salt intake increases vascular stiffness in humans, especially in salt-sensitive populations. While we recently suggested that the endothelial sodium channel (EnNaC) contributes to salt-sensitivity related endothelial cell (EC) and arterial stiffening, mechanistic understanding remains incomplete. This study therefore aimed to explore the role of EC-serum and glucocorticoid regulated kinase 1 (SGK1), as a reported regulator of sodium channels, in EC and arterial stiffening. METHODS AND RESULTS A mouse model of salt sensitivity-associated vascular stiffening was produced by subcutaneous implantation of slow-release deoxycorticosterone acetate (DOCA) pellets, with salt (1 % NaCl, 0.2 % KCl) administered via drinking water. Preliminary data showed that global SGK1 deletion caused significantly decreased blood pressure (BP), EnNaC activity and aortic endothelium stiffness as compared to control mice following DOCA-salt treatment. To probe EC signaling pathways, selective deletion of EC-SGK1 was performed by cross-breeding cadherin 5-Cre mice with sgk1flox/flox mice. DOCA-salt treated control mice had significantly increased BP, EC and aortic stiffness in vivo and ex vivo, which were attenuated by EC-SGK1 deficiency. To demonstrate relevance to humans, human aortic ECs were cultured in the absence or presence of aldosterone and high salt with or without the SGK1 inhibitor, EMD638683 (10uM or 25uM). Treatment with aldosterone and high salt increased intrinsic stiffness of ECs, which was prevented by SGK1 inhibition. Further, the SGK1 inhibitor prevented aldosterone and high salt induced actin polymerization, a key mechanism in cellular stiffening. CONCLUSION EC-SGK1 contributes to salt-sensitivity related EC and aortic stiffening by mechanisms appearing to involve regulation of actin polymerization.

Sleep efficiency and PTSD symptom severity predict microvascular endothelial function and arterial stiffness in young, trauma-exposed women. Am J Physiol Heart Circ Physiol 2023; 325:H739-H750. [PMID: 37505472 PMCID: PMC10642999 DOI: 10.1152/ajpheart.00169.2023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 07/13/2023] [Accepted: 07/28/2023] [Indexed: 07/29/2023]
Abstract
Posttraumatic stress disorder (PTSD) is linked to sleep disturbances and significantly higher risk of developing cardiovascular disease (CVD). Furthermore, vascular dysfunction and sleep are independently associated with CVD. Uncovering the link between PTSD symptom severity, sleep disturbances, and vascular function could shine a light on mechanisms of CVD risk in trauma-exposed young women. The purpose of the present study was to investigate the individual and combined effects of sleep efficiency and PTSD symptom severity on vascular function. We recruited 60 otherwise healthy women [age, 26 ± 7 yr and body mass index (BMI), 27.7 ± 6.5 kg/m2] who had been exposed to trauma. We objectively quantified sleep efficiency (SE) using actigraphy, microvascular endothelial function via Framingham reactive hyperemia index (fRHI), and arterial stiffness via pulse-wave velocity (PWV). PTSD symptom severity was assessed using the PTSD checklist for fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (PCL5). PWV was correlated with age (r = 0.490, P < 0.001) and BMI (r = 0.484, P < 0.001). In addition, fRHI was positively correlated with SE (r = 0.409, P = 0.001) and negatively correlated with PTSD symptoms (r = -0.382, P = 0.002). To explore the predictive value of SE and PTSD symptoms on PWV and fRHI, we conducted two multivariate linear regression models. The model predicting PWV was significant (R2 = 0.584, P < 0.001) with age, BMI, blood pressure, and SE emerging as predictors. Likewise, the model predicting fRHI was significant (R2 = 0.360, P < 0.001) with both PTSD symptoms and SE as significant predictors. Our results suggest that although PTSD symptoms mainly impact microvascular endothelial function, sleep efficiency is additionally associated with arterial stiffness in young trauma-exposed women, after controlling for age and BMI.NEW & NOTEWORTHY This is the first study to investigate the individual and combined impacts of objective sleep and PTSD symptoms severity on arterial stiffness and microvascular endothelial function in young premenopausal women. We report that in young trauma-exposed women, although low sleep efficiency is associated with overall vascular function (i.e., microvascular endothelial function and arterial stiffness), the severity of PTSD symptoms is specifically associated with microvascular endothelial function, after accounting for age and body mass index.

Abstract
BACKGROUND Estimated pulse wave velocity (ePWV) has been proposed as a potential approach to assess carotid-femoral pulse wave velocity (cfPWV). However, the potential ability of ePWV to predict all-cause and cause-specific mortality in the population group with hypertension remains unresolved. METHODS We conducted a prospective cohort study using the data of 14 044 adults (age ≥18 years) from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2014, and followed this cohort until the end of December 2019. ePWV was calculated by using a regression equation for age and mean blood pressure (MBP), derived by the Arterial Stiffness Collaborative Group. RESULTS The weighted mean age of the 14 044 adults included was 54.79 years; 49.42% of all participants were men. During the median follow-up period of 11 years, 3795 deaths were recorded. In the fully adjusted cox regression model, each 1 m/s increase in ePWV was associated with an increased risk of 56% [hazard ratio 1.61; 95% confidence interval (CI) 1.49-1.64] risk for all-cause mortality. Every 1 m/s increase in ePWV resulted in an increased risk of mortality from cardiovascular disease, cerebrovascular disease, respiratory disease, Alzheimer's disease, accidents, cancer, influenza and pneumonia by 60, 70, 47, 118, 73, 41 and 103%, respectively. ePWV has a robust predictive value for 5- and 10-year all-cause mortality in the hypertensive population with AUCs of 0.749 and 0.741, respectively. CONCLUSION Elevated ePWV is positively correlated with all-cause mortality and most cause-specific mortalities, independent of traditional risk factors. Moreover, ePWV demonstrates high accuracy in predicting 5-year and 10-year all-cause mortality, outperforming Framingham Risk Score.

Subject-Specific Pressure Normalization of Local Pulse Wave Velocity: Separating Intrinsic From Acute Load-Dependent Stiffening in Hypertensive Patients. Front Physiol 2022; 12:783457. [PMID: 35242043 PMCID: PMC8886155 DOI: 10.3389/fphys.2021.783457] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Accepted: 12/14/2021] [Indexed: 11/21/2022] Open
Abstract
Pulse wave velocity (PWV) is a powerful predictor of cardiovascular events. However, its intrinsic blood pressure (BP)-dependency complicates distinguishing between acute and chronic effects of increased BP on arterial stiffness. Based on the assumption that arteries exhibit a nearly exponential pressure-area (P-A) relationship, this study proposes a method to assess intersubject differences in local PWV independently from BP. The method was then used to analyze differences in local carotid PWV (cPWV) between hypertensive and healthy normotensive people before and after BP-normalization. Pressure (P) and diameter (D) waveforms were simultaneously acquired via tonometer at the left and ultrasound scanning at right common carotid artery (CCA), respectively, in 22 patients with Grade 1 or 2 hypertension and 22 age- and sex-matched controls. cPWV was determined using the D2P-loop method. Then, the exponential modeling of the P-area (A = πD2/4) relationships allowed defining a mathematical formulation to compute subject-specific changes in cPWV associated with BP changes, thus enabling the normalization of cPWV against intersubject differences in BP at the time of measurement. Carotid systolic BP (SBP) and diastolic BP (DBP) were, on average, 17.7 (p < 0.001) and 8.9 mmHg (p < 0.01) higher in hypertensives than controls, respectively. cPWV was 5.56 ± 0.86 m/s in controls and 6.24 ± 1.22 m/s in hypertensives. BP alone accounted for 68% of the cPWV difference between the two groups: 5.80 ± 0.84 vs. 6.03 ± 1.07 m/s after BP-normalization (p = 0.47). The mechanistic normalization of cPWV was in agreement with that estimated by analysis of covariance (ANCOVA). In conclusion, the proposed method, which could be easily implemented in the clinical setting, allows to assess the intersubject differences in PWV independently of BP. Our results suggested that mild hypertension in middle-aged subjects without target organ damage does not significantly alter the stiffness of the CCA wall independently of acute differences in BP. The results warrant further clinical investigations to establish the potential clinical utility of the method.

Abstract
The prognostic importance of changes in aortic stiffness for the occurrence of adverse cardiovascular outcomes and mortality has never been investigated in patients with resistant hypertension. We aimed to evaluate it in a prospective cohort of 442 resistant hypertension individuals. Changes in aortic stiffness were assessed by 2 carotid-femoral pulse wave velocity (CF-PWV) measurements performed over a median time interval of 4.7 years. Multivariate Cox analysis examined the associations between changes in CF-PWV (evaluated as continuous variables and categorized into quartiles and as increased/persistently high or reduced/persistently low) and the occurrence of total cardiovascular events (CVEs), major adverse CVEs, and cardiovascular/all-cause mortalities. During a median follow-up of 4.1 years after the second CF-PWV measurement, there were 49 total CVEs (42 major adverse CVEs) and 53 all-cause deaths (32 cardiovascular). As continuous variables, increments in absolute and relative changes in CF-PWV were associated with higher risks of CVEs and major adverse CVEs occurrence, but not of mortality. Divided into quartiles of CF-PWV changes, risks increased in the third and fourth quartile subgroups in relation to the reference first quartile subgroup (those with greatest CF-PWV reductions) for all outcomes. Patients who either increased or persisted with high CF-PWV had excess risks of cardiovascular morbidity/mortality, with hazard ratios ranging from 2.7 to 3.0, in relation to those who reduced or persisted with low CF-PWV values. In conclusion, reducing or preventing progression of aortic stiffness was associated with significant cardiovascular protection in patients with resistant hypertension, suggesting that it may be an additional clinical target of antihypertensive treatment.

Abstract
BACKGROUND Diabetes is most commonly associated with aortic stiffness, but the importance of nondiabetic glucometabolic status for aortic stiffness (AS) in hypertension patients is unclear. METHODS We included 1065 hypertension patients without diabetes in a cohort study. Carotid-femoral pulse wave velocity (cfPWV) >10 m/s can broadly be defined as AS. Pearson correlation analysis and multiple regression analysis are used to reveal the relationship between elevated fasting blood glucose (FBG) and AS. RESULTS The 1065 hypertension patients (mean age 60 years) included 48% male, 22% smokers, 94.3% with anti-hypertensive drugs, 17.9% with AS, 80% with abdominal obesity, 42% with elevated triglycerides (TG), and 27% with elevated FBG. The mean values for office systolic blood pressure (SBP)/diastolic blood pressure (DBP) and central SBP/DBP were 130/85mmHg and 132/86mmHg. Mean cfPWV was 8.7m/s. Multiple regression analysis revealed that age, office SBP, and elevated FBG were independently related to AS in the whole hypertension. Elevated FBG had 1.6-fold risk of AS in hypertension patients compared with below the cutoff. In subgroup analysis, elevated FBG increased 2.68-fold risk for AS in those without metabolic syndrome (MS), not in MS. The area under curve (AUC) of office SBP was higher than central SBP for AS in receiver operating characteristic (ROC) analysis. CONCLUSION We found that elevated FBG was an independent risk factor for AS in hypertension patients without MS, although there was a high proportion of abdominal obesity. Office SBP was better than central SBP to assess AS in community hypertension.

Abstract
It is not clear whether the influence of arterial stiffness depends on the subject's cardiovascular risk status. This study was performed to assess the prognostic value of arterial stiffness according to different cardiovascular risk profiles. A total of 11,767 subjects (61 years and 58% males) who underwent brachial-ankle pulse wave velocity (baPWV) measurement were retrospectively analyzed. Subjects were stratified into three groups: (1) those with traditional risk factor ≤1 and without atherosclerotic cardiovascular disease (ASCVD), (2) those with traditional risk factors ≥2 and without ASCVD, or (3) those with documented ASCVD. Composite events of cardiac death, non-fatal myocardial infarction, coronary revascularization and stroke were assessed during the clinical follow-up period. Compared to patients with risk factor ≤1, those with risk factor ≥2 and those with ASCVD were older, and more frequently had unfavorable laboratory findings, and higher baPWV values. During the median follow-up of 1329 days (interquartile range, 570-1,965 days), there were 350 composite events (3.0%). In multivariable Cox regression analyses, higher baPWV value was independently associated with higher incidence rate of composite events even after controlling for potential confounders in all three groups (P < 0.05 for each). In this study, it was found that baPWV was independently associated with the occurrence of cardiovascular events irrespective of baseline cardiovascular risk profiles, suggesting that baPWV is useful for risk stratification in mass screening.

Abstract
BACKGROUND Physical activity is associated with reduced arterial stiffness, although such a relationship has not been reported in those with resistant hypertension. Therefore, this study aimed to determine the association between daily physical activity and arterial stiffness in patients with resistant hypertension. METHODS Fifty-seven (57) patients with resistant hypertension (50.9% men), aged 58.8±9.4 years, were consecutively recruited. Arterial stiffness was evaluated using carotid-femoral pulse wave velocity (cf-PWV). Daily physical activity was objectively assessed with accelerometers during 7 consecutive days. RESULTS Patients had a body mass index of 29.0±4.0 kg/m2 (84.3% overweight/obese) and were taking an average 4.5 antihypertensive medications. Overall, the cf-PWV was 9.2±2.4 m/s and the majority of participants (n=41, 71.9%) presented a cf-PWV <10 m/s. The cf-PWV showed an inverse correlation with light-intensity physical activity (r = -0.290, p=0.029) and total daily physical activity (r = -0.287, p=0.030). The correlation between light physical activity and cf-PWV remained significant after adjustment for systolic and diastolic blood pressure, but lost significance when further adjusted for age. CONCLUSIONS Higher daily levels of light-intensity and total physical activity were associated with lower arterial stiffness. Nonetheless, this association is weak and attenuated or abolished when adjusted for blood pressure and age. These results suggest that physical activity may play an important role as a lifestyle intervention for patients with resistant hypertension. Future studies with larger samples sizes are necessary to confirm this preliminary data.

Abstract
Arterial stiffness, defined as the rigidity of the arterial wall, is the consequence of vascular aging and is associated with the full spectrum of cardiovascular diseases. Carotid-femoral pulse wave velocity (cf-PWV) is the gold standard method for arterial stiffness evaluation: it measures the velocity of the arterial pulse along the thoracic and abdominal aorta alongside arterial distensibility. Its value rises as stiffness progresses. Cf-PWV is helpful to assess residual cardiovascular risk (CVR) in hypertension (HT). In fact, an increase in pulsatility and arterial stiffness predicts CVR in patients affected by arterial HT, independently of other risk factors. Arterial stiffness can predict cardiovascular events in several other clinical conditions such as heart failure, diabetes, and pulmonary HT. However, cf-PWV has not been yet included in routine clinical practice so far. A possible reason might be its methodological and theoretical limitations (inaccuracy in the traveled distance, intra and interindividual variability, lack of well-defined references values, and age- and blood pressure-independent cutoff). To exceed these limits a strict adherence to guidelines, use of analytical approaches, and possibility of integrating the results with other stiffness examinations are essential approaches.

Abstract
Arterial stiffening, a characteristic feature of obesity and type 2 diabetes, contributes to the development and progression of cardiovascular diseases (CVD). Currently, no effective prophylaxis or therapeutics is available to prevent or treat arterial stiffening. A better understanding of the molecular mechanisms underlying arterial stiffening is vital to identify newer targets and strategies to reduce CVD burden. A major contributor to arterial stiffening is increased collagen deposition. In the 5'-untranslated regions of mRNAs encoding for type I collagen, an evolutionally conserved stem-loop (SL) structure plays an essential role in its stability and post-transcriptional regulation. Here, we show that feeding a high-fat/high-sucrose (HFHS) diet for 28 wk increases adiposity, insulin resistance, and blood pressure in male wild-type littermates. Moreover, arterial stiffness, assessed in vivo via aortic pulse wave velocity, and ex vivo using atomic force microscopy in aortic explants or pressure myography in isolated femoral and mesenteric arteries, was also increased in those mice. Notably, all these indices of arterial stiffness, along with collagen type I levels in the vasculature, were reduced in HFHS-fed mice harboring a mutation in the 5'SL structure, relative to wild-type littermates. This protective vascular phenotype in 5'SL-mutant mice did not associate with a reduction in insulin resistance or blood pressure. These findings implicate the 5'SL structure as a putative therapeutic target to prevent or reverse arterial stiffening and CVD associated with obesity and type 2 diabetes.NEW & NOTEWORTHY In the 5'-untranslated (UTR) regions of mRNAs encoding for type I collagen, an evolutionally conserved SL structure plays an essential role in its stability and posttranscriptional regulation. We demonstrate that a mutation of the SL mRNA structure in the 5'-UTR decreases collagen type I deposition and arterial stiffness in obese mice. Targeting this evolutionarily conserved SL structure may hold promise in the management of arterial stiffening and CVD associated with obesity and type 2 diabetes.

Abstract
Several important findings bearing on the prevention, detection, and management of hypertension have been reported since publication of the 2017 American College of Cardiology/American Heart Association Blood Pressure Guideline. This review summarizes and places in context the results of relevant observational studies, randomized clinical trials, and meta-analyses published between January 2018 and March 2021. Topics covered include blood pressure measurement, patient evaluation for secondary hypertension, cardiovascular disease risk assessment and blood pressure threshold for drug therapy, lifestyle and pharmacological management, treatment target blood pressure goal, management of hypertension in older adults, diabetes, chronic kidney disease, resistant hypertension, and optimization of care using patient, provider, and health system approaches. Presenting new information in each of these areas has the potential to increase hypertension awareness, treatment, and control which remain essential for the prevention of cardiovascular disease and mortality in the future.

Abstract
OBJECTIVE The prognostic importance of the nocturnal blood pressure (BP) fall and early-morning surge were scarcely investigated in patients with resistant hypertension (RHT). We investigated them in a prospective cohort of 1726 RHT individuals. METHODS The nocturnal fall and morning surge were calculated from the baseline ambulatory BP monitoring (ABPM) and also as mean cumulative values using all ABPMs performed during follow-up. Dipping patterns (normal, extreme, reduced, and reverse) were defined by classic cut-off values of the night-to-day ratio, while MS (difference between early-morning and night-time BP) was categorized into quartiles and at the extremes of its distribution (5th, 10th, 90th, and 95th percentiles). The primary outcomes were total cardiovascular events (CVEs), major adverse cardiovascular events (MACEs), all-cause and cardiovascular mortalities. Multivariate Cox analyses examined the associations between nocturnal BP fall and morning surge and outcomes. RESULTS Over a median follow-up of 8.3 years, 417 CVEs occurred (358 MACEs), and 391 individuals died (233 cardiovascular deaths). Reduced and reverse dipping patterns were significant predictors of CVEs and MACEs, with hazard ratios between 1.6 and 2.5, whereas extreme dipping was a protective factor in younger individuals (hazard ratios 0.3--0.4) but a hazardous factor in elderly (hazard ratios 3.7--5.0) and in individuals with previous cardiovascular diseases (hazard ratios 2.6--4.4). No morning surge parameter was predictive of any outcome in fully adjusted analyses. CONCLUSION Abnormal dipping patterns but not the early-morning BP surge, were important prognostic markers for future cardiovascular morbidity in RHT patients. The prognosis of extreme dippers depended on age and the presence of cardiovascular diseases.

Abstract
Background The long‐term prognosis of refractory hypertension (RfHT), defined as failure to control blood pressure (BP) levels despite an antihypertensive treatment with ≥5 medications including a diuretic and mineraloreceptor antagonist, has never been evaluated. Methods and Results In a prospective cohort study with 1576 patients with resistant hypertension, patients were classified as refractory or nonrefractory based on uncontrolled clinic (or office) and ambulatory BPs during the first 2 years of follow‐up. Multivariate Cox analyses examined the associations between the diagnosis of RfHT and the occurrence of total cardiovascular events (CVEs), major adverse CVEs, and cardiovascular and all‐cause mortality, after adjustments for other risk factors. In total, 135 patients (8.6%) had RfHT by uncontrolled ambulatory BPs and 167 (10.6%) by uncontrolled clinic BPs. Over a median Follow‐Up of 8.9 years, 338 total CVEs occurred (288 major adverse CVEs, including 124 myocardial infarctions, and 96 strokes), and 331 patients died, 196 from cardiovascular causes. The diagnosis of RfHT, using either classification by clinic or ambulatory BPs, was associated with significantly higher risks of major adverse CVEs, cardiovascular mortality, and stroke incidence, with hazard ratios varying from 1.54 to 2.14 in relation to patients with resistant nonrefractory hypertension; however, the classification based on ambulatory BPs was better in identifying higher risk patients than the classification based on clinic BP levels. Conclusions Patients with RfHT, particularly when defined by uncontrolled ambulatory BP levels, had higher risks of major adverse CVEs and mortality in relation to patients with resistant but nonrefractory hypertension, supporting the concept of refractory hypertension as a true extreme phenotype of antihypertensive treatment failure.

Impaired l-arginine-nitric oxide pathway contributes to the pathogenesis of resistant hypertension. Clin Sci (Lond) 2020; 133:2061-2067.

Abstract
The precise mechanisms underlying resistant hypertension remain elusive. Reduced nitric oxide (NO) bioavailability is frequently documented in chronic kidney disease, obesity, diabetes and advanced age, all of which are risk factors for resistant hypertension. Sympathetic overactivity and chronic activation of the renin-angiotensin system are salient features of resistant hypertension. Interestingly, recent data indicate that renal sympathetic overactivity can reduce the expression of neuronal nitric oxide synthase in the paraventricular nucleus. Reduced NO levels in the paraventricular nucleus can increase sympathetic outflow and this can create a vicious cycle contributing to resistant hypertension. Angiotensin II can reduce l-arginine transport and hence NO production. Reduced NO levels may reduce the formation of angiotensin 1-7 dampening the cardio-protective effects of the renin-angiotensin system contributing to resistant hypertension. In addition, interleukin-6 (IL-6) is demonstrated to be independently associated with resistant hypertension, and IL-6 can reduce NO synthesis. Despite this, NO levels have not been quantified in resistant hypertension. Findings from a small proof of concept study indicate that NO donors can reduce blood pressure in patients with resistant hypertension but more studies are required to validate these preliminary findings. In the present paper, we put forward the hypothesis that reduced NO bioavailability contributes substantially to the development of resistant hypertension.

Abstract
The prognostic importances of on-treatment clinic and ambulatory blood pressure (BP) levels have never been investigated in individuals with resistant hypertension. We aimed to evaluate them for the occurrence of incident cardiovascular and mortality outcomes in a prospective cohort of 1726 patients with resistant hypertension. Clinic and ambulatory BPs were measured at baseline and serially during follow-up (analyzed as time-varying and as mean cumulative BPs) and also categorized as controlled/uncontrolled as defined by the traditional and new 2017 American College of Cardiology/American Heart Association criteria. Multivariate Cox analyses examined the associations between BP parameters and the occurrence of total cardiovascular events, major adverse cardiovascular events, and cardiovascular and all-cause mortalities. C statistics and the integrated discrimination improvement indexes evaluated the improvement in risk discrimination. Over a median follow-up of 8.3 years, 417 total cardiovascular events occurred (358 major adverse cardiovascular events) and 391 individuals died (233 cardiovascular deaths). All single systolic BP (SBP) parameters significantly predicted all outcomes, but the associations were stronger for ambulatory SBPs than for clinic SBPs and for on-treatment SBPs (particularly for mean cumulative) than for baseline SBPs, and both improved risk discrimination (with increases in C statistic of up to 0.021 and integrated discrimination improvements of up to 19.7%). These findings were consistent for diastolic BPs. Uncontrolled ambulatory BPs were associated with higher risks for all outcomes, whereas uncontrolled clinic BPs were not. In conclusion, mean cumulative ambulatory BPs during follow-up were the best prognostic markers of adverse cardiovascular outcomes and mortality in patients with resistant hypertension. Serial ambulatory BP monitoring shall be more widely used in resistant hypertension management.
