Projected Impact of Nonpharmacologic Management of Stage 1 Hypertension Among Lower-Risk US Adults.

The 2017 American College of Cardiology/American Heart Association blood pressure guideline classified 31 million US adults as having stage 1 hypertension and recommended clinicians provide counseling on behavioral change to the low-risk portion of this group. However, nationwide reductions in cardiovascular disease (CVD) and associated health care expenditures achievable by nonpharmacologic therapy remain unquantified. We simulated interventions on a target population of US adults aged 35 to 64 years, identified from the 2015-2018 National Health and Nutrition Examination Survey, with low-risk stage 1 systolic hypertension: that is, untreated systolic blood pressure 130 to 139 mm Hg with diastolic BP <90 mm Hg; no history of CVD, diabetes, or chronic kidney disease; and a low 10-year risk of CVD. We used meta-analyses and trials to estimate the effects of population-level behavior modification on systolic blood pressure. We assessed the extent to which restricting intervention to those in regular contact with clinicians might prevent the delivery of nonpharmacologic therapy. Controlling systolic blood pressure to <130 mm Hg among the 8.8 million low-risk US adults with stage 1 hypertension could prevent 26 100 CVD events, avoid 2900 deaths, and save $1.7 billion in total direct health care costs over 10 years. Adoption of the Dietary Approaches to Stop Hypertension diet could prevent 28 000 CVD events. Other nonpharmacologic interventions could avert between 3800 and 19 500 CVD events. However, only 51% of men and 75% of women regularly interacted with clinicians for counseling opportunities. Among low-risk adults with stage 1 hypertension, substantial benefits to cardiovascular health could be achieved through public policy that promotes the adoption of nonpharmacologic therapy.

Predicted Cardiovascular Risk by the PREVENT Equations in US Adults With Stage 1 Hypertension.

The 2017 American College of Cardiology/American Heart Association blood pressure guideline recommends initiation of antihypertensive medication for adults with stage 1 hypertension (systolic blood pressure, 130-139 mm Hg, or diastolic blood pressure, 80-89 mm Hg) and 10-year atherosclerotic cardiovascular disease (ASCVD) risk ≥10% estimated by the pooled cohort equations (PCEs). In 2023, the American Heart Association published the predicting risk of cardiovascular disease events (PREVENT) equations to estimate ASCVD and total cardiovascular disease risk. We analyzed US National Health and Nutrition Examination Survey data from 2013 to 2020 for 1703 adults aged 30 to 79 years without self-reported cardiovascular disease with stage 1 hypertension. We estimated 10-year ASCVD risk by the PCEs and 10-year ASCVD and total cardiovascular disease risk by the base PREVENT equations. Analyses were weighted to represent noninstitutionalized US adults with stage 1 hypertension. Mean 10-year ASCVD risk was 5.4% (95% CI, 5.0%-5.9%) and 2.9% (95% CI, 2.7%-3.1%) using the PCEs and PREVENT equations, respectively. The proportion with 10-year ASCVD risk of 10% to <15% and ≥15% was 8.1% and 7.8% estimated by the PCEs, respectively, and 3.0% and 0.3% estimated by the PREVENT equations, respectively. No participants had a 10-year ASCVD risk ≥10% on the PREVENT equations and <10% on the PCEs, while 12.5% had a 10-year ASCVD risk ≥10% on the PCEs and <10% on the PREVENT equations. The mean 10-year total cardiovascular disease risk estimated by the PREVENT equations was lower than the mean 10-year ASCVD risk on the PCEs. Among US adults with stage 1 hypertension, the 10-year predicted ASCVD risk estimated by the PREVENT equations was approximately half the risk estimated by the PCEs.

Abstract 09: The Diagnostic Accuracy of Using Borderline High Office Blood Pressure Thresholds to Diagnose Masked Hypertension According to the 2017 American College of Cardiology / American Heart Association Blood Pressure Guideline

Background: Compared to adults with sustained normotension (i.e. those with neither high office blood pressure [BP] nor high out-of-office BP), adults with masked hypertension (i.e. those with high out-of-office BP but not high office BP) have an increased risk of cardiovascular disease events. The 2017 American College of Cardiology (ACC)/American Heart Association (AHA) BP guideline recommends using ambulatory BP monitoring (ABPM) to detect masked hypertension among adults with an office BP close to the high BP threshold (i.e. office systolic BP [SBP] 120 to &lt;130 mmHg or diastolic BP [DBP] 75 to &lt;80 mmHg) and not taking antihypertensive medication (Class IIa recommendation). Limited data exist on the diagnostic accuracy of using this approach to detect masked hypertension. Methods: We analyzed data from the Improving the Detection of Hypertension Study, a community-based study of adult participants, from Upper Manhattan, not taking antihypertensive medication. Office BP was measured using a validated Omron oscillometric device (Model HEM-790IT or HEM-791IT) and ABPM was performed using a validated Spacelabs device (Model 90207). Sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), false positive rate (FPR), and false negative rate (FNR) of having an office SBP 120 to &lt;130 mmHg or DBP 75 to &lt;80 mmHg for the diagnosis of high BP on ABPM were determined among 263 participants who had a mean SBP &lt;130 mmHg and mean DBP &lt;80 mmHg based on 6 SBP and 6 DBP readings from the first 2 visits (i.e. 3 SBP and 3 DBP readings per visit), and a sufficient number of ABPM readings (i.e. ≥10 awake and ≥5 asleep readings). High BP on ABPM was defined as mean awake SBP ≥130 mmHg or mean awake DBP ≥80 mmHg as per the 2017 ACC/AHA BP guideline. In a sensitivity analysis, high BP on ABPM was defined as mean 24-hour SBP ≥125 mmHg or mean 24-hour DBP ≥75 mmHg. Results: Mean (SD) age was 39.2 (12.8) years, 62.4% were female, 16.7% were non-Hispanic White, 14.4% were non-Hispanic Black, 6.8% were non-Hispanic Asian, 60.8% were Hispanic, and 1.3% were Other race/ethnicity. Of the 263 participants, 101 (38.4%) had an office SBP 120 to &lt;130 mmHg or DBP 75 to &lt;80 mmHg, and 69 (26.2%) had high BP on ABPM (awake SBP/DBP ≥130/80 mmHg). SN, SP, PPV, NPV, FPR, and FNR were 75.4%, 74.7%, 51.5%, 89.5%, 25.3%, and 24.6%, respectively. When using mean 24-hour SBP/DBP to define high BP on ABPM, SN, SP, PPV, NPV, FPR, and FNR were 72.7%, 75.8%, 55.4%, 87.0%, 24.2%, and 27.3%, respectively. Conclusions: The 2017 ACC/AHA BP guideline currently would require only 38.4% of participants with mean office BP &lt;130/80 mmHg to be screened with ABPM for masked hypertension using a screening office BP threshold of SBP 120 to &lt;130 mmHg or DBP 75 to &lt;80 mmHg. However, this approach had a substantial rate of false positives and false negatives. Investigation of alternative diagnostic screening approaches for masked hypertension is needed.

Cumulative Diastolic Blood Pressure Burden in Normal Systolic Blood Pressure and Cardiovascular Disease.

The clinical significance of isolated diastolic hypertension defined by the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guidelines remains inconsistent. We examined whether long-term diastolic burden predicts the first major adverse cardiovascular event in participants with sustained and untreated normal systolic BP. The Mass General Brigham Biobank is a New England health care-based cohort recruited between 2010 and 2021. A total of 15 979 participants aged 18 to 64 years and without prior cardiovascular disease, antihypertensives, or high systolic BP were studied. The cumulative diastolic burden was determined as the area under the curve for diastolic BP (DBP) ≥80 mm Hg over 5 years before enrollment. Major adverse cardiovascular event was defined as a composite of first incident ischemic heart disease, stroke, heart failure, or all-cause death. Of the 15 979 participants, mean (SD) age at enrollment was 47.6 (14.3) years, 11 950 (74.8%) were women, and the mean (SD) systolic BP and DBP were 118.0 (12.9) and 72.2 (9.3) mm Hg, respectively. Over a median (interquartile range) follow-up of 3.5 (1.8-5.4) years, 2467 (15.4%) major adverse cardiovascular events occurred. Using Cox proportional hazards regression, each SD increase in cumulative DBP was independently associated with a hazard ratio (95% CI) of 1.06 (1.02-1.10) without effect modification by sex (P=0.65), age (P=0.46), or race/ethnicity (P=0.24). In addition to traditional risk factors, cumulative DBP modestly improved the discrimination C index (95% CI) from 0.74 (0.72-0.75) to 0.75 (0.74-0.76; likelihood ratio test, P=0.037). Among individuals with normal systolic BP, cumulative DBP may augment cardiovascular disease risk stratification beyond a single DBP measure and traditional risk factors.

Thiazide Diuretic Utilization Within the VA.

The 2017 American College of Cardiology/American Heart Association blood pressure guideline recommends chlorthalidone as the preferred thiazide diuretic. We aimed to better understand thiazide prescribing patterns within the US Department of Veterans Affairs (VA). A retrospective analysis was conducted of patients with a prescription for hydrochlorothiazide (HCTZ), chlorthalidone, indapamide, or any combination products containing these from January 1, 2016, to January 21, 2022. The primary objective was to determine the utilization rates of each thiazide in the active cohort, assessed via χ2 test with Bonferroni correction. Secondary objectives included concomitant potassium or magnesium supplementation, blood pressure rates and control, and thiazide use from January 1, 2016, to December 31, 2021. Of 628,994 active thiazide prescriptions, utilization rates differed significantly between thiazide groups (P < .001). Rates for HCTZ, chlorthalidone, and indapamide were 84.6%, 14.9%, and 0.5%, respectively. HCTZ use decreased from 90.2% to 83.5% (P < .001) and chlorthalidone use increased from 9.3% to 16.0% (P < .001). Between thiazide groups, rates of blood pressure control were not significantly different (P = .58). Potassium or magnesium supplementation was significantly different between groups (P < .001). The highest concomitant supplementation was with indapamide followed by chlorthalidone and HCTZ with rates of 27.1%, 22.6%, and 12.4%, respectively. Despite guideline recommendations for chlorthalidone, HCTZ is the most prescribed thiazide diuretic within the VA. However, there was a significant trend toward increased chlorthalidone prescribing from 2016 to 2021. Application of these data may guide further research to increase guideline-recommended therapy.

Abstract P147: Cumulative Diastolic Blood Pressure Burden In Normal Systolic Blood Pressure And Cardiovascular Disease

Introduction: The clinical significance of isolated diastolic hypertension defined by the 2017 American College of Cardiology/American Heart Association Blood Pressure (BP) Guideline remains controversial. We examined whether long-term diastolic burden independently predicts the first major adverse cardiovascular event (MACE) in participants with sustained untreated normal systolic BP. Methods: We identified 18,181 Mass General Brigham Biobank participants aged 18 to 64 years with untreated systolic BP &lt;130 mmHg. Cumulative diastolic burden was determined as the area under curve for diastolic BP (DBP) ≥80 mmHg over a 5-year period prior to enrollment. Hazard ratio (HR) between cumulative diastolic burden and MACE was estimated using Cox proportional hazards regression. Prognostic value of enrollment and cumulative DBP was compared. Results: Of the 18,181 participants, mean [SD] age at enrollment was 47.6 [14.3] years, 13,574 [74.7%] were female, and 2853 (15.7%) MACE occurred over a median [IQR] follow-up of 3.5 [1.9-5.3] years. Each SD increase in cumulative DBP was associated with HR (95% CI) of 1.07 (1.03-1.11), adjusting for age, sex, race, body mass index, systolic BP, lipids, diabetes, smoking, statin, and antihypertensives initiation during follow-up. In addition to traditional risk factors, cumulative DBP improved the discrimination C index (95% CI) from 0.732 (0.724-0.742) to 0.739 (0.732-0.748) (Likelihood ratio test P =0.021), whereas inclusion of enrollment DBP did not improve prognosis. Conclusions: Among individuals with normal systolic BP, cumulative DBP may augment risk stratification beyond a single DBP measure and other traditional risk factors.

Association of stage 1 hypertension defined by the 2017 ACC/AHA guideline with cardiovascular events and mortality in Chinese adults.

The 2017 American College of Cardiology/American Heart Association (ACC/AHA) blood pressure (BP) guideline lowered the threshold defining hypertension to 130/80 mmHg. However, how stage 1 hypertension defined using this guideline is associated with cardiovascular events in Chinese adults remains unclear. This study assessed the association between stage 1 hypertension defined by the 2017 ACC/AHA guideline and clinical outcomes in the Chinese population. Participants with stage 1 hypertension ( n = 69,509) or normal BP ( n = 34,142) were followed in this study from 2006/2007 to 2020. Stage 1 hypertension was defined as a systolic blood pressure of 130-139 mmHg or a diastolic blood pressure of 80-89 mmHg. None were taking antihypertensive medication or had a history of myocardial infarction (MI), stroke, or cancer at baseline. The primary outcome was a composite of MI, stroke, and all-cause mortality. The secondary outcomes were individual components of the primary outcome. Cox proportional hazards models were used for the analysis. During a median follow-up of 11.09 years, we observed 10,479 events (MI, n = 995; stroke, n = 3408; all-cause mortality, n = 7094). After multivariable adjustment, the hazard ratios for stage 1 hypertension vs. normal BP were 1.20 (95% confidence interval [CI], 1.13-1.25) for primary outcome, 1.24 (95% CI, 1.05-1.46) for MI, 1.45 (95% CI, 1.33-1.59) for stroke, and 1.11 (95% CI, 1.04-1.17) for all-cause mortality. The hazard ratios for participants with stage 1 hypertension who were prescribed antihypertensive medications compared with those without antihypertensive treatment during the follow-up was 0.90 (95% CI, 0.85-0.96). Using the new definition, Chinese adults with untreated stage 1 hypertension are at higher risk for MI, stroke, and all-cause mortality. This finding may help to validate the new BP classification system in China.

The 2017 American College of Cardiology/American Heart Association Hypertension Guideline and Blood Pressure in Older Adults

The 2017 American College of Cardiology/American Heart Association blood pressure guideline redefined hypertension and lowered the blood pressure treatment target. Empirical data on the guideline's impact are needed. Data were analyzed from Atherosclerosis Risk in Communities study participants who attended baseline pre-guideline (2016-2017) and post-guideline (2018-2019) visits with baseline systolic blood pressure between 120 and 159 mmHg. Participants were grouped according to baseline systolic blood pressure by change in classification under the new guideline as follows: not reclassified (120-129 mmHg), reclassified to Stage 1 hypertension (130-139 mmHg), and reclassified to Stage 2 hypertension (140-159 mmHg). Means and 95% CIs for systolic blood pressure changes between baseline and follow-up, changes in antihypertensive use, and percentages that achieved the post-guideline recommendation (systolic blood pressure <130 mmHg) were calculated. Analyses were performed in 2021-2022. Among 2,193 community-dwelling Atherosclerosis Risk in Communities participants aged 71-95 years at baseline, systolic blood pressure changes between baseline and follow-up visits differed among participants not reclassified (+4.1 mmHg, 95% CI=3.0, 5.3 mmHg), reclassified to Stage 1 hypertension (-1.1 mmHg, 95% CI= -2.2, 0.1 mmHg), and reclassified to Stage 2 hypertension (-5.7 mmHg, 95% CI= -6.8, -4.7 mmHg). Antihypertensive use changed from 77.3% to 78.4% (p=0.25) among participants reclassified to Stage 1 hypertension and from 78.3% to 81.4% (p<0.01) among participants reclassified to Stage 2 hypertension. At follow-up, 41.8% of the Stage 1 and 22.4% of the Stage 2 hypertension groups reached the systolic blood pressure <130 mmHg goal. There were small decreases in systolic blood pressure and increases in antihypertensive therapy among older adults reclassified to Stage 2 hypertension but not among those reclassified to Stage 1 hypertension by the 2017 American College of Cardiology/American Heart Association guideline.

Hypertension Statistics for US Adults: An Open-Source Web Application for Analysis and Visualization of National Health and Nutrition Examination Survey Data.

Data from the US National Health and Nutrition Examination Survey are freely available and can be analyzed to produce hypertension statistics for the noninstitutionalized US population. The analysis of these data requires statistical programming expertise and knowledge of National Health and Nutrition Examination Survey methodology. We developed a web-based application that provides hypertension statistics for US adults using 10 cycles of National Health and Nutrition Examination Survey data, 1999 to 2000 through 2017 to 2020. We validated the application by reproducing results from prior publications. The application's interface allows users to estimate crude and age-adjusted means, quantiles, and proportions. Population counts can also be estimated. To demonstrate the application's capabilities, we estimated hypertension statistics for noninstitutionalized US adults. The estimated mean systolic blood pressure (BP) declined from 123 mm Hg in 1999 to 2000 to 120 mm Hg in 2009 to 2010 and increased to 123 mm Hg in 2017 to 2020. The age-adjusted prevalence of hypertension (ie, systolic BP≥130 mm Hg, diastolic BP≥80 mm Hg or self-reported antihypertensive medication use) was 47.9% in 1999 to 2000, 43.0% in 2009 to 2010, and 44.7% in 2017 to 2020. In 2017 to 2020, an estimated 115.3 million US adults had hypertension. The age-adjusted prevalence of controlled BP, defined by the 2017 American College of Cardiology/American Heart Association BP guideline, among nonpregnant US adults with hypertension was 9.7% in 1999 to 2000, 25.0% in 2013 to 2014, and 21.9% in 2017 to 2020. After age adjustment and among nonpregnant US adults who self-reported taking antihypertensive medication, 27.5%, 48.5%, and 43.0% had controlled BP in 1999 to 2000, 2013 to 2014, and 2017 to 2020, respectively. The application developed in the current study is publicly available at https://bcjaeger.shinyapps.io/nhanesShinyBP/ and produced valid, transparent and reproducible results.

Sex Differences in the Association Between Hypertension and Incident Atrial Fibrillation.

Background Limited evidence is available on sex differences about the association between hypertension and incident atrial fibrillation (AF). Methods and Results We used a nationwide health checkup and claims database to analyze 3 383 738 adults (median age, 43 (36-51) years, 57.4% men). We investigated the relationship between hypertension and incident AF in men and women using a Cox regression model. We used restricted cubic spline functions to identify the association of blood pressure (BP) as a continuous parameter with incident AF. We categorized the men and women into 4 groups according to the 2017 American College of Cardiology/American Heart Association BP guidelines. During a mean follow-up of 1199±950 days, 13 263 AF diagnoses were recorded. The incidence (95% CI) of AF was 15.8 (15.5-16.1) per 10 000 person-years in men and 6.1 (5.9-6.3) per 10 000 person-years in women. Compared with normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension were associated with an increased risk AF in both men and women. However, the hazard ratios were greater in women than in men, and the P value for interactions in the multivariable model was 0.0076. The models using restricted cubic spline showed that the risk of AF associated with elevated systolic BP increased steeply above an approximate threshold of systolic BP of 130 mm Hg in men and 100 mm Hg in women. Although our primary findings were consistent across subgroup analyses, this association was most significant in younger individuals. Conclusions Although the incidence of AF was higher in men, the association between hypertension and incident AF was more pronounced in women than in men, suggesting a potential sex difference in the relationship between hypertension and incident AF.

Isolated systolic or diastolic hypertension and mortality risk in young adults using the 2017 American College of Cardiology/American Heart Association blood pressure guideline: a longitudinal cohort study.

Little is known regarding the health effects of different hypertension phenotypes including isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic and diastolic hypertension (SDH) defined by the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guideline among young adults. We conducted this longitudinal study using time-varying analyses to evaluate the relationship between cardiovascular/all-natural mortality risk and different hypertension phenotypes in young adults. A total of 284 597 young adults (aged 18-39 years) were recruited between 1996 and 2016. Participants were classified into eight mutually exclusive BP groups: normal blood pressure (BP), elevated BP, stage 1 IDH, stage 1 ISH, stage 1 SDH, stage 2 IDH, stage 2 ISH, and stage 2 SDH. The outcomes were cardiovascular and all-natural mortality. After a median follow-up of 15.8 years, 2341 all-natural deaths with 442 cardiovascular deaths were observed. When compared with individuals with normal BP, the multivariable adjusted hazard ratios (95% confidence interval) of cardiovascular mortality was 1.39 (1.01-1.93) for elevated BP, 2.00 (1.45-2.77) for stage 1 IDH, 1.66 (1.08-2.56) for stage 1 ISH, 3.08 (2.13-4.45) for stage 1 SDH, 2.85 (1.76-4.62) for stage 2 IDH, 4.30 (2.96-6.25) for stage 2 ISH, and 6.93 (4.99-9.61) for stage 2 SDH, respectively. In consideration to all-natural mortality, similar results were observed for stage 1 SDH, stage 2 ISH, and stage 2 SDH; but not for elevated BP, stage 1 IDH, stage 1 ISH, and stage 2 IDH. Young adults with stage 1 or stage 2 ISH, IDH, and SDH are at increased risk of cardiovascular death than those with normal BP. Regardless of BP stage, SDH was associated with a higher cardiovascular mortality risk than IDH and ISH.

Correction to: Association of Blood Pressure Classification Using the 2017 American College of Cardiology/American Heart Association Blood Pressure Guideline With Risk of Heart Failure and Atrial Fibrillation

Association between retinal vein occlusion and early-stage hypertension: A propensity score analysis using a large claims database.

The threshold of hypertension was lowered from systolic blood pressure (SBP)/diastolic blood pressure (DBP) 140/90 mmHg to 130/80 mmHg by the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guideline. Thus, we investigated the association between retinal vein occlusion (RVO) occurrence and early-stage hypertension. This retrospective cohort study used the JMDC Claims Database (JMDC Inc., Tokyo, Japan) between 2005 and 2020. Individuals undergoing health checkups who had data on BP and did not take antihypertensive medications were included. They were classified into four BP groups: normal BP (SBP < 120 mmHg and DBP < 80 mmHg), elevated BP (SBP 120-129 mmHg and DBP < 80 mmHg), stage 1 hypertension (SBP 130-139 mmHg or DBP 80-89 mmHg), and stage 2 hypertension (SBP ≥ 140 mmHg or DBP ≥ 90 mmHg). Date of RVO occurrence was defined as the first date of diagnosis. We estimated adjusted hazard ratios for RVO and central RVO using weighted Cox regression to adjust for potential confounders. A total of 2,703,264 individuals were eligible. During a mean follow-up of 1,091 days, 3,526 RVO and 828 central RVO events occurred. The adjusted hazard ratios (95% confidence intervals) were 1.37 (1.19-1.57), 1.95 (1.75-2.18), and 3.33 (2.95-3.76) for RVO and 1.44 (1.07-1.93), 2.17 (1.72-2.73), and 3.76 (2.91-4.86) for central RVO in the elevated BP, stage 1 hypertension, and stage 2 hypertension groups, respectively, compared with the normal BP group. Even individuals with early-stage hypertension showed higher risks for RVO and central RVO than individuals with normal BP.

Blood Pressure Classification Using the 2017 ACC/AHA Guideline and Heart Failure in Patients With Cancer.

Despite the growing recognition of the importance of hypertension in patients with cancer, little is known about whether high blood pressure (BP) among patients with cancer is associated with incident heart failure (HF) and other cardiovascular disease (CVD) events and what BP levels are linked to these events. We examined the association of BP classification on the basis of the 2017 American College of Cardiology/American Heart Association BP guideline with the risk of HF and CVD events in patients with cancer. We studied 33,991 patients with a history of breast, colorectal, or stomach cancer (median age, 53 years; 34.1% men). Patients receiving treatment with BP-lowering medications or having a history of CVD including HF were excluded. Using BP measurements at baseline, 33,991 participants were categorized as having normal BP (n = 17,444), elevated BP (n = 4,733), stage 1 hypertension (n = 7,502), or stage 2 hypertension (n = 4,312). The primary outcome was HF. Over a mean follow-up of 2.6 ± 2.2 years, 779 HF events were recorded. After multivariable adjustment, the hazard ratios (HRs) for HF were 1.15 (95% CI, 0.93 to 1.44) for elevated BP, 1.24 (95% CI, 1.03 to 1.49) for stage 1 hypertension, and 1.99 (95% CI, 1.63 to 2.43) for stage 2 hypertension. A stepwise increase in risk with BP categories was also observed in other CVD events. This association was observed even in patients undergoing active cancer treatment. The relationship between hypertension and the risk of developing HF in patients with cancer was confirmed in the Korean National Health Insurance Service database. Medication-naïve stage 1 and 2 hypertension was associated with a greater risk of HF and other CVD events in patients with cancer. Our results suggest the importance of multidisciplinary collaboration (eg, oncologists and cardiologists) to establish the optimal management strategy for hypertension in patients with cancer.

Comparison of the association of masked hypertension defined by the 2017 ACC/AHA BP guideline versus the JNC7 guideline with left ventricular hypertrophy.

Background:Compared with the Seventh Report of the Joint National Committee (JNC7), the 2017 American College of Cardiology/American Heart Association (ACC/AHA) blood pressure (BP) guideline uses lower BP thresholds to define hypertension and BP control.Methods:We pooled data from five US-based studies to compare the association of masked hypertension (MHT) and masked uncontrolled hypertension, defined using the 2017 ACC/AHA guideline (n = 1653 without high office BP; <130/80 mmHg) versus the JNC7 guideline (n = 2451 without high office BP; <140/90 mmHg), with left ventricular hypertrophy (LVH). MHT and masked uncontrolled hypertension were defined using office BP and awake BP alone and awake, asleep, or 24-h BP. LVH was assessed by echocardiography.Results:Among participants without high office BP not taking antihypertensive medication, the prevalence of MHT defined by the JNC7 guideline and the 2017 ACC/AHA BP guideline was 25.0 and 33.5% using awake BP only and 37.1 and 52.0% when using awake, asleep, or 24-h BP. The adjusted prevalence ratios for LVH associated with MHT versus sustained normotension defined by the JNC7 and 2017 ACC/AHA BP guidelines were 1.72 [95% confidence interval (CI): 1.12–2.64] and 1.56 (95% CI: 0.97–2.51), respectively, when using awake BP only and 2.16 (95% CI: 1.36–3.44) and 1.03 (95% CI: 0.58–1.82), respectively, when using awake, asleep or 24-h BP. There was no evidence that masked uncontrolled hypertension was associated with LVH when defined using the BP thresholds in either the JNC7 or the 2017 ACC/AHA BP guideline.Conclusion:The association of MHT with LVH may depend on the BP thresholds used.

Blood Pressure Control Among Non-Hispanic Black Adults Is Lower Than Non-Hispanic White Adults Despite Similar Treatment With Antihypertensive Medication: NHANES 2013-2018.

BACKGROUNDControlled blood pressure can prevent or reduce adverse health outcomes. Social and structural determinants may contribute to the disparity that despite equivalent proportions on antihypertensive medication, non-Hispanic Black (Black) adults have lower blood pressure control and more cardiovascular events than non-Hispanic White (White) adults.METHODSData from 2013 to 2018 National Health and Nutrition Examination Survey were pooled to assess control among Black and White adults by antihypertensive medication use and selected characteristics using the 2017 American College of Cardiology/American Heart Association (ACC/AHA) Blood Pressure Guideline definition (systolic blood pressure <130 mm Hg and diastolic blood pressure <80 mm Hg) among 4,739 adults.RESULTSAmong those treated with antihypertensive medication, an estimated 34.9% of Black and 45.0% of White adults had controlled blood pressure. Control was lower for Black and White adults among most subgroups of age, sex, education, insurance status, usual source of care, and poverty–income ratio. Black adults had higher use of diuretics (28.5%—Black adults vs. 23.5%—White adults) and calcium channel blockers (24.2%—Black adults vs. 14.7%—White adults) compared with White adults. Control among Black adults was lower than White adults across all medication classes including diuretics (36.1%—Black adults vs. 47.3%—White adults), calcium channel blockers (30.2%—Black adults vs. 40.1%—White adults), and number of medication classes used.CONCLUSIONSSuboptimal blood pressure control rates and disparities warrant increased efforts to improve control, which could include addressing social and structural determinants along with emphasizing implementation of the 2017 ACC/AHA Blood Pressure Guideline into clinical practice.

Application of the 2017 American college of cardiology/American Heart Association Blood Pressure Guidelines for cardiovascular outcomes among Tehranian residents.

To evaluate the associations of cardiovascular disease (CVD) outcomes with elevated blood pressure (BP), stage I of isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic diastolic hypertension (SDH), defined by 2017 ACC/AHA guidelines among the Tehranian adult population. We enrolled 7068 residents of Tehran (district No. 13) aged at least 30 years, who were free of CVD and not taking antihypertensive medications at baseline. Participants were categorized into eight categories: normal BP (reference group), elevated BP, stage I IDH, stage I ISH, stage I SDH, and all stage II phenotypes. Significant interactions were found between age groups (<60 versus ≥60 years) and BP categories (P value: 0.017); hence, the analysis was performed in each age group, separately. We used multivariable Cox proportional regression analysis to evaluate the association of different BP categories with incident CVD. During 18years of follow-up, 1053 CVD events occurred. In the younger group, stage I of IDH and SDH were associated with increased CVD risk with hazard ratios (HRs) of 1.23 (95% confidence interval: 0.99-1.52) and 1.42 (1.04-1.94), respectively. In the older group, stage I of IDH had a lower risk for coronary heart disease (CHD) [HR 0.53 (0.29-0.96)]. As a sensitivity analysis, among high CVD risk individuals (10-year risk ≥10%), we found a higher risk for CVD among those with elevated BP and stage I of SDH. For individuals with 10-year risk less than 10%, all BP parameters, except stage I of IDH, were associated with increased CVD risk. Although there was no significant interaction between sex and BP categories, elevated BP and stage I of SDH significantly increased the risk of CVD only among men. Age is an important potential modifier in the association between stage I of hypertension and CVD/CHD risk. Stage I of IDH was not an alarming status for CVD development, whether the participants had a high CVD risk or not.

Stage 1 hypertension and risk of cardiovascular disease mortality in United States adults with or without diabetes.

This study aimed to investigate the association of S1 hypertension, classified according to the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guideline, with cardiovascular disease (CVD) mortality in adults with or without diabetes from the general United States population. This cohort study included 40 518 United States adults (including 3555 with diabetes) naive to antihypertensive drugs who attended the National Health and Nutrition Examination Surveys from 1988 to 2014. Participants were followed up for 489 679 person-years (mean follow-up, 12.1 years) with 1569 CVD deaths being recorded. S1 hypertension was neither associated with an increased CVD mortality risk in the whole cohort nor in participants with or without diabetes after full adjustment. In age-stratified analyses, compared with normal BP, S1 hypertension was associated with increased CVD mortality in young adults, unrelated to CVD mortality in midlife, and associated with lower CVD mortality in the elderly. In older participants (≥70 years), people with S1 hypertension had a 23% lower multivariate-adjusted CVD mortality risk compared with those with normal BP (hazard ratio 0.77; 95% confidence interval 0.61-0.98). In younger (<70 years) adults without diabetes, people with normal BP had the lowest CVD mortality risk; however, in younger adults with diabetes, it was people with elevated BP who had the lowest CVD mortality risk. In this representative sample of United States adults not on BP-lowering medications, S1 hypertension was associated with elevated CVD mortality in younger adults and with lower CVD mortality in those 70 or more years of age.

Risk for Proteinuria in Newly Defined Hypertensive People Based on the 2017 American College of Cardiology/American Heart Association Blood Pressure Guideline

Whether blood pressure (BP) classification using the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) BP guideline can identify patients at high risk for proteinuria remains unknown. We examined the association of BP classification using the 2017 ACC/AHA guideline with the subsequent risk for the development of proteinuria. This is an observational cohort study using the JMDC Claims Database. We analyzed 914,786 participants with negative proteinuria assessed using urine dipstick tests at the initial health check-ups, not taking BP-lowering medications, and who underwent repeated urine dipstick tests within 4 years. Based on the 2017 ACC/AHA guideline, each participant was categorized as having normal BP (n=487,020), elevated BP (n=134,798), stage 1 hypertension (n=197,618), or stage 2 hypertension (n=95,350). The primary outcome was incident proteinuria. We investigated the association of BP based on the 2017 ACC/AHA guideline category with incident proteinuria using multivariable analyses. We used restricted cubic spline functions to identify the relation between systolic BP (SBP) and the risk for proteinuria. The median age was 45 years, and 59.4% were men. Multivariable analysis demonstrated that stage 1 hypertension (relative risk 1.14, 95% confidence interval 1.11 to 1.17), and stage 2 hypertension (relative risk 1.48, 95% confidence interval 1.43 to 1.52) were associated with a higher incidence of proteinuria than normal BP. The restricted cubic spline demonstrated that the risk for proteinuria increased linearly with SBP after SBP exceeded 120 mm Hg. Not only stage 2 hypertension but also stage 1 hypertension was associated with a greater risk for proteinuria, suggesting the importance of establishing the management strategy for stage 1 hypertension.

Predicting Out-of-Office Blood Pressure in a Diverse US Population.

BACKGROUNDThe PRedicting Out-of-OFfice Blood Pressure (PROOF-BP) algorithm accurately predicted out-of-office blood pressure (BP) among adults with suspected high BP in the United Kingdom and Canada. We tested the accuracy of PROOF-BP in a diverse US population and evaluated a newly developed US-specific algorithm (PROOF-BP-US).METHODSAdults with ≥2 office BP readings and ≥10 awake BP readings on 24-hour ambulatory BP monitoring from 4 pooled US studies were included. We compared mean awake BP with predicted out-of-office BP using PROOF-BP and PROOF-BP-US. Our primary outcomes were hypertensive out-of-office systolic BP (SBP) ≥130 mm Hg and diastolic BP (DBP) ≥80 mm Hg.RESULTSWe included 3,058 adults, mean (SD) age was 52.0 (11.9) years, 38% were male, and 54% were Black. The area under the receiver-operator characteristic (AUROC) curve (95% confidence interval) for hypertensive out-of-office SBP was 0.81 (0.79–0.82) and DBP was 0.76 (0.74–0.78) for PROOF-BP. For PROOF-BP-US, the AUROC curve for hypertensive out-of-office SBP was 0.82 (0.81–0.83) and for DBP was 0.81 (0.79–0.83). The optimal predicted out-of-office BP ranges for out-of-office BP measurement referral were 120–134/75–84 mm Hg for PROOF-BP and 125–134/75–84 mm Hg for PROOF-BP-US. The 2017 American College of Cardiology/American Heart Association BP guideline (referral range 130–159/80–99 mm Hg) would refer 93.1% of adults not taking antihypertensive medications with office BP ≥130/80 mm Hg in the National Health and Nutrition Examination Survey for out-of-office BP measurement, compared with 53.1% using PROOF-BP and 46.8% using PROOF-BP-US.CONCLUSIONSPROOF-BP and PROOF-BP-US accurately predicted out-of-office hypertension in a diverse sample of US adults.
