Background The Systolic Blood Pressure Intervention Trial (SPRINT) demonstrated an intensive (<120 mm Hg) vs. standard (<140 mm Hg) systolic blood pressure (SBP) goal lowered cardiovascular disease (CVD) risk. Estimating the effect of intensive SBP lowering among SPRINT-eligible adults most likely to benefit can guide implementation efforts. Methods We studied SPRINT participants and SPRINT-eligible participants in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study and National Health and Nutrition Examination Surveys (NHANES). A published algorithm of predicted CVD benefit with intensive SBP treatment was used to categorize participants into low, medium, or high predicted benefit. CVD event rates were estimated with intensive and standard treatment. Results Median age was 67.0, 72.0, and 64.0 years in SPRINT, SPRINT-eligible REGARDS, and SPRINT-eligible NHANES participants, respectively. The proportion with high predicted benefit was 33.0% in SPRINT, ...
Has the SPRINT trial introduced a new blood-pressure goal in hypertension?
Nature reviews. Cardiology, 2017
SPRINT is the first randomized, controlled trial showing that a systolic blood-pressure goal of <120 mmHg can be attained with cardiovascular benefits in a select group of patients with hypertension and an elevated cardiovascular risk with different origins. Although the patient population with characteristics like those in SPRINT makes up only 20-30% of the total hypertensive population, SPRINT is a landmark study that highlights the need to consider lower blood- pressure goals in the treatment of hypertension. Extending this study to include other patient populations and geographical areas is the next step for evaluating the benefits of strict blood-pressure targets and the generalizability of the SPRINT results. Importantly, the blood-pressure measurement method used in SPRINT differs from previous clinical trials, and raises the issue of whether a more accurate method should be used in clinical trials and if such method is feasible in clinical practice. This Perspectives arti...

Intensive systolic blood pressure (SBP) control improved outcomes in SPRINT (Systolic Blood Pressure Intervention Trial). Our objective was to expand on reported findings by analysis of baseline characteristics, primary outcomes, adverse events, follow-up blood pressure, and medication use differences by baseline SBP (tertile 1 [T1], <132; tertile 2 [T2], 132-145; and tertile 3 [T3], >145 mm Hg). Participants with higher baseline SBP tertile were more often women and older, had higher cardiovascular risk, and lower utilization of antihypertensive medications, statins, and aspirin. Achieved SBP in both treatment arms was slightly higher in T2 and T3 compared with T1 and fewer in the T3 groups achieved SBP targets compared with T1 and T2 groups. The primary composite outcome with intensive versus standard SBP treatment was reduced by 30% in T1, 23% in T2, and 17% in T3 with no evidence of an interaction (=0.77). Event rates were lower in the intensive arm, and there was no evide...

In SPRINT (Systolic Blood Pressure Intervention Trial), patients with hypertension and high cardiovascular risk treated with intensive blood pressure (BP) control (<120 mm Hg) had fewer major adverse cardiovascular events (MACE) and deaths but higher rates of treatment-related serious adverse events (SAE) than patients randomized to standard BP control (<140 mm Hg). However, the degree of benefit or harm for an individual patient could vary because of heterogeneity in treatment effect. Using patient-level data from 9361 randomized patients in SPRINT, we developed models to predict risk for MACE or death and treatment-related SAE to allow for individualized BP treatment goals based on each patient's projected risk and benefit of intensive versus standard BP control. Models were internally validated using bootstrap resampling and externally validated on 4741 patients from the ACCORD-BP (The Action to Control Cardiovascular Risk in Diabetes blood pressure) trial. Among 9361 S...

Objective-We evaluated the incidence of cardiovascular disease (CVD) in individuals whose blood pressure (BP) management strategy would change with adoption of recent US hypertension guidelines in two large, community-based cohorts with different racial and geographic compositions: the Framingham and Jackson Heart Studies (FHS and JHS). Methods-We assigned 11,237 FHS (mean age 46, 53% women) and 2948 JHS (mean age 55, 69% women) participants free of chronic kidney disease to one of five categories representing different treatment recommendations between JNC 8 and JNC 7 guidelines. Absolute incidence rates (IR; per 1000 person-years) and multivariable-adjusted hazard ratios (HR) were calculated for each group; cohort-specific results were combined using fixed effect meta-analysis. Results-CVD events occurred in 1047 FHS and 230 JHS participants during mean follow-up times of 11 and 8.9 years, respectively. Compared to individuals without hypertension, those with BP 140-149/<90 mm Hg had increased risk for CVD regardless of treatment status (HR for untreated BP 140-149/<90 mm Hg 1.96, 95% confidence interval [CI] 1.40-2.75; HR for treated BP 140-149/<90 mm Hg 3.37, 95% CI 2.37-4.78). The risk for those with treated BP 140-149/<90 mm Hg was consistent in those aged ≥60 years (HR: 2.61, 95% CI 1.75-3.90). Statistical power was limited to evaluate the effect of diabetes.

US blood pressure reduction policies are largely restricted to hypertensive populations and associated benefits are often estimated based on unrealistic interventions. We used multivariable linear regression to estimate incidence rate differences contrasting the impact of 2 pragmatic hypothetical interventions to reduce coronary heart disease, stroke, and heart failure (HF) incidence: (1) a population-wide intervention that reduced systolic blood pressure by 1 mm Hg and (2) targeted interventions that reduced the prevalence of unaware, untreated, or uncontrolled blood pressure above goal (per Eighth Joint National Committee treatment thresholds) by 10%. In the Atherosclerosis Risk in Communities Study (n=15 744; 45 to 64 years at baseline, 1987-1989), incident coronary heart disease and stroke were adjudicated by physician panels. Incident HF was defined as the first hospitalization with discharge diagnosis code of "428." A 10% proportional reduction in unaware, untreated,...

Background -The 2017 American College of Cardiology/American Heart Association (ACC/AHA) Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults provides recommendations for the definition of hypertension, systolic and diastolic blood pressure (BP) thresholds for initiation of antihypertensive medication and BP target goals. The objective of this study was to determine the prevalence of hypertension, implications of recommendations for antihypertensive medication and prevalence of BP above the treatment goal among US adults using criteria from the 2017 ACC/AHA and the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC7) guidelines. Methods -We analyzed data from the 2011-2014 National Health and Nutrition Examination Survey (N=9,623). NHANES (National Health and Nutrition Examination Survey) participants completed study interviews and an examination. For each partic...
Implications of New Hypertension Guidelines in the United States
Hypertension, 2011
The American Heart Association Task Force released a scientific statement in 2007 for the treatment of hypertension in the prevention of coronary artery disease (CAD). These guidelines recommend more aggressive control of blood pressure (BP) among those at high risk for CAD: individuals with diabetes mellitus, chronic kidney disease, cardiovascular disease, congestive heart failure, or a 10-year Framingham risk score Ն10%. These individuals are advised to maintain a BP Ͻ130/80 mm Hg. We estimated the burden of uncontrolled BP among those at an increased risk of CAD using the updated task force guidelines. We used a cross-sectional analysis of National Health and Nutrition Examination Survey 2005-2008 participants. Participants were 24 989 adults aged 18 to 85 years. Using the old definition of hypertension (Ͼ140/90 mm Hg), 98 million (21%) Americans have hypertension. Using the updated guidelines, an additional 52 million (11%) American adults now have elevated BP requiring treatment, for a total of 150 million adults (32%). Adults with diabetes mellitus have the greatest population burden of uncontrolled BP (50.6 million), followed by adults with chronic kidney disease (43.7 million) and cardiovascular disease (43.3 million). Although individuals at a higher risk for CAD are more likely to be aware of their hypertension and to be taking antihypertension medication, they are less likely to have their BP under control. Additional efforts are needed in the treatment of elevated BP, especially among individuals with an increased risk of CAD. (Hypertension. 2011;58:361-366.)

Background In the 2017 ACC/AHA hypertension guidelines, a 10-year risk of more than 10% is considered for initiation of intensive blood pressure reduction. The current study aimed to determine which cut off limit of cardiovascular risk for starting intensive blood pressure reduction is beneficial. Design A Secondary Analysis of Systolic Blood Pressure Intervention Trial (SPRINT). Methods Data from the SPRINT Trial was obtained from the NHLBI Data Repository Center. In the SPRINT, non-diabetic participants with SBP of ≥ 130 mmHg were randomly assigned to intensive and standard treatment arms with SBP targets of < 120 and < 140 mmHg, respectively. This study analyzed data from non-diabetic participants less than 75 years of age without cardiovascular or chronic kidney disease. The primary composite outcome was myocardial infarction, and other acute coronary syndromes, stroke, heart failure, or death from cardiovascular causes. Cox regression models were used to examine the risk ...
