Potential Cardiovascular Disease Events Prevented with Adoption of the 2017 American College of Cardiology/American Heart Association Blood Pressure Guideline.

ABSTRACT: BACKGROUND:Over 10 years, achieving and maintaining 2017 ACC/AHA guideline goals could prevent 3.0 million (UR, 1.1-5.1 million), 0.5 million (UR, 0.2-0.7 million), and 1.4 million (UR, 0.6-2.0 million) cardiovascular disease (CVD) events compared with maintaining current blood pressure (BP) levels, achieving 2003 Seventh Joint National Committee Report goals, and achieving 2014 Eighth Joint National Committee goals, respectively. We estimated the number of cardiovascular disease events prevented and treatment-related serious adverse events incurred over 10 years among US adults with hypertension by achieving 2017 ACC/AHA guideline-recommended BP goals compared with (1) current BP levels, (2) achieving 2003 Seventh Joint National Committee Report BP goals, and (3) achieving 2014 Eighth Joint National Committee panel member report BP goals. METHODS:US adults aged ?45 years with an indication for BP treatment were grouped according to recommendations for antihypertensive drug therapy in the 2017 ACC/AHA guideline, 2003 Seventh Joint National Committee Report, and 2014 Eighth Joint National Committee. Population sizes were estimated from the 2011 to 2014 National Health and Nutrition Examination Surveys. Rates for fatal and nonfatal CVD events (stroke, coronary heart disease, or heart failure) were estimated from the REGARDS (REasons for Geographic And Racial Differences in Stroke) study, weighted to the US population. CVD risk reductions with treatment to BP goals and risk for serious adverse events were obtained from meta-analyses of BP-lowering trials. CVD events prevented and treatment-related nonfatal serious adverse events over 10 years were calculated. Uncertainty surrounding main data inputs was expressed in uncertainty ranges (UR). RESULTS:Over ten years, achieving and maintaining 2017 ACC/AHA guideline goals compared with current BP levels, achieving 2003 Seventh Joint National Committee Report goals, or achieving 2014 Eighth Joint National Committee goals could prevent 3.0 million (UR, 1.1-5.1 million), 0.5 million (UR, 0.2-0.7 million), or 1.4 million (UR, 0.6-2.0 million) CVD events, respectively. Compared with current BP levels, achieving and maintaining 2017 goals could prevent 71.9 (UR, 26.6-122.3) CVD events per 1000 treated. Achieving 2017 guideline BP goals compared with current BP levels could also lead to nearly 3.3 million more serious adverse events over 10 years (UR, 2.2-4.4 million). CONCLUSIONS:Achieving and maintaining 2017 ACC/AHA BP goals could prevent a greater number of CVD events than achieving 2003 Seventh Joint National Committee Report or 2014 Eighth Joint National Committee BP goals but could also lead to more serious adverse events.

Project description:ImportanceLittle is known regarding the association between level of blood pressure (BP) in young adulthood and cardiovascular disease (CVD) events by middle age.ObjectiveTo assess whether young adults who developed hypertension, defined by the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) BP guideline, before age 40 years have higher risk for CVD events compared with those who maintained normal BP.Design, setting, and participantsAnalyses were conducted in the prospective cohort Coronary Artery Risk Development in Young Adults (CARDIA) study, started in March 1985. CARDIA enrolled 5115 African American and white participants aged 18 to 30 years from 4 US field centers (Birmingham, Alabama; Chicago, Illinois; Minneapolis, Minnesota; and Oakland, California). Outcomes were available through August 2015.ExposuresUsing the highest BP measured from the first examination to the examination closest to, but not after, age 40 years, each participant was categorized as having normal BP (untreated systolic BP [SBP] <120 mm Hg and diastolic BP [DBP] <80 mm Hg; n = 2574); elevated BP (untreated SBP 120-129 mm Hg and DBP <80 mm Hg; n = 445); stage 1 hypertension (untreated SBP 130-139 mm Hg or DBP 80-89 mm Hg; n = 1194); or stage 2 hypertension (SBP ≥140 mm Hg, DBP ≥90 mm Hg, or taking antihypertensive medication; n = 638).Main outcomes and measuresCVD events: fatal and nonfatal coronary heart disease (CHD), heart failure, stroke, transient ischemic attack, or intervention for peripheral artery disease (PAD).ResultsThe final cohort included 4851 adults (mean age when follow-up for outcomes began, 35.7 years [SD, 3.6]; 2657 women [55%]; 2441 African American [50%]; 206 taking antihypertensive medication [4%]). Over a median follow-up of 18.8 years, 228 incident CVD events occurred (CHD, 109; stroke, 63; heart failure, 48; PAD, 8). CVD incidence rates for normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension were 1.37 (95% CI, 1.07-1.75), 2.74 (95% CI, 1.78-4.20), 3.15 (95% CI, 2.47-4.02), and 8.04 (95% CI, 6.45-10.03) per 1000 person-years, respectively. After multivariable adjustment, hazard ratios for CVD events for elevated BP, stage 1 hypertension, and stage 2 hypertension vs normal BP were 1.67 (95% CI, 1.01-2.77), 1.75 (95% CI, 1.22-2.53), and 3.49 (95% CI, 2.42-5.05), respectively.Conclusions and relevanceAmong young adults, those with elevated blood pressure, stage 1 hypertension, and stage 2 hypertension before age 40 years, as defined by the blood pressure classification in the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines, had significantly higher risk for subsequent cardiovascular disease events compared with those with normal blood pressure before age 40 years. The ACC/AHA blood pressure classification system may help identify young adults at higher risk for cardiovascular disease events.

Project description:ImportanceThe 2013 American College of Cardiology/American Heart Association (ACC/AHA) Cholesterol Management Guideline recommends moderate-intensity to high-intensity statin therapy in eligible patients.ObjectiveTo examine adoption of the 2013 ACC/AHA guideline in US cardiology practices.Design, setting, and participantsAmong 161 cardiology practices, trends in the use of moderate-intensity to high-intensity statin and nonstatin lipid-lowering therapy (LLT) were analyzed before (September 1, 2012, to November 1, 2013) and after (February 1, 2014, to April 1, 2015) publication of the 2013 ACC/AHA guideline among 4 mutually exclusive risk groups within the ACC Practice Innovation and Clinical Excellence Registry. Interrupted time series analysis was used to evaluate for differences in trend in use of moderate-intensity to high-intensity statin and nonstatin LLT use in hierarchical logistic regression models. Participants were a population-based sample of 1 105 356 preguideline patients (2 431 192 patient encounters) and 1 116 472 postguideline patients (2 377 219 patient encounters). Approximately 97% of patients had atherosclerotic cardiovascular disease (ASCVD).ExposuresModerate-intensity to high-intensity statin and nonstatin LLT use before and after publication of the 2013 ACC/AHA guideline.Main outcomes and measuresTime trend in the use of moderate-intensity to high-intensity statin and nonstatin LLT.ResultsIn the study cohort, the mean (SD) age was 69.6 (12.1) years among 1 105 356 patients (40.2% female) before publication of the guideline and 70.0 (11.9) years among 1 116 472 patients (39.8% female) after publication of the guideline. Although there was a trend toward increasing use of moderate-intensity to high-intensity statins overall and in the ASCVD cohort, such a trend was already present before publication of the guideline. No significant difference in trend in the use of moderate-intensity to high-intensity statins was observed in other groups. The use of moderate-intensity to high-intensity statin therapy was 62.1% (before publication of the guideline) and 66.6% (after publication of the guideline) in the overall cohort, 62.7% (before publication) and 67.0% (after publication) in the ASCVD cohort, 50.6% (before publication) and 52.3% (after publication) in the cohort with elevated low-density lipoprotein cholesterol levels (ie, ≥190 mg/dL), 52.4% (before publication) and 55.2% (after publication) in the diabetes cohort, and 41.9% (before publication) and 46.9% (after publication) in the remaining group with 10-year ASCVD risk of 7.5% or higher. In hierarchical logistic regression models, there was a significant increase in the use of moderate-intensity to high-intensity statins in the overall cohort (4.8%) and in the ASCVD cohort (4.3%) (P < .01 for slope for both). There was no significant change for other risk cohorts. Nonstatin LLT use remained unchanged in the preguideline and postguideline periods in the hierarchical logistic regression models for all of the risk groups.Conclusions and relevanceAdoption of the 2013 ACC/AHA Cholesterol Management Guideline in cardiology practices was modest. Timely interventions are needed to improve guideline-concordant practice to reduce the burden of ASCVD.

Project description:ImportanceAmong young adults, the association of the 2017 American College of Cardiology/American Heart Association (ACC/AHA) High Blood Pressure Clinical Practice Guidelines with risk of cardiovascular disease (CVD) later in life is uncertain.ObjectiveTo determine the association of blood pressure categories before age 40 years with risk of CVD later in life.Design, setting, and participantsThis population-based cohort study from the Korean National Health Insurance Service consisted of 2 488 101 adults aged 20 through 39 years with blood pressure measurements taken twice from 2002 through 2005. Starting from January 1, 2006, participants were followed up until the date of CVD diagnosis, death, or December 31, 2015.ExposuresParticipants were categorized by blood pressure readings: normal (systolic, <120 mm Hg; diastolic, <80 mm Hg), elevated (sytolic, 120-129 mm Hg; diastolic, <80 mm Hg), stage 1 hypertension (systolic, 130-139 mm Hg; diastolic, 80-89 mm Hg), and stage 2 hypertension (systolic, ≥140 mm Hg; diastolic, ≥90 mm Hg).Main outcomes and measuresThe primary outcome was CVD defined as 2 or more days of hospitalization due to CVD or death due to CVD. The secondary outcomes were coronary heart disease (CHD) and stroke.ResultsThe study population consisted of 2 488 101 participants (median age, 31 years [interquartile range, 27-36 years], 789 870 women [31.7%]). A total of 44 813 CVD events were observed during a median follow-up duration of 10 years. Men with baseline stage 1 hypertension compared with those with normal blood pressure had higher risk of CVD (incidence, 215 vs 164 per 100 000 person-years; difference, 51 per 100 000 person-years [95% CI, 48-55]; adjusted hazard ratio [HR], 1.25 [95% CI, 1.21-1.28]), CHD (incidence, 134 vs 103 per 100 000 person-years; difference, 31 per 100 000 person-years [95% CI, 28-33]; adjusted HR, 1.23 [95% CI, 1.19-1.27]), and stroke (incidence, 90 vs 67 per 100 000 person-years; difference, 23 per 100 000 person-years [95% CI, 21-26]; adjusted HR, 1.30 [95% CI, 1.25-1.36]). Women with baseline stage 1 hypertension compared with those with normal blood pressure had increased risk of CVD (incidence, 131 vs 91 per 100 000 person-years; difference, 40 per 100 000 person-years [95% CI, 35-45]; adjusted HR, 1.27 [95% CI, 1.21-1.34]), CHD (incidence, 56 vs 42 per 100 000 person-years; difference, 14 per 100 000 person-years [95% CI, 11-18]; adjusted HR, 1.16 [95% CI, 1.08-1.25]), and stroke (incidence, 79 vs 51 per 100 000 person-years; difference, 28 per 100 000 person-years [95% CI, 24-32]; adjusted HR [1.37, 95% CI, 1.29-1.46]). Results for state 2 hypertension were consistent.Conclusions and relevanceAmong Korean young adults, stage 1 and stage 2 hypertension, compared with normal blood pressure, were associated with increased risk of subsequent cardiovascular disease events. Young adults with hypertension, defined by the 2017 ACC/AHA criteria, may be at increased risk of cardiovascular disease.

Project description:ObjectivesThe AHA/ACC-2017 hypertension guideline recommends an age-independent target blood pressure (BP) of less than 130/80 mmHg. In an elderly cohort without established cardiovascular disease (CVD) at baseline, we determined the impact of this guideline on the prevalence of hypertension and associated CVD risk.MethodsNineteen thousand, one hundred and fourteen participants aged at least 65 years from the ASPirin in Reducing Events in the Elderly (ASPREE) study were grouped by baseline BP: 'pre-2017 hypertensive' (BP ≥140/90 mmHg and/or on antihypertensive drugs); 'reclassified hypertensive' (normotensive by pre-2017 guidelines; hypertensive by AHA/ACC-2017 guideline), and 'normotensive' (BP <130 and <80 mmHg). For each group, we evaluated CVD risk factors, predicted 10-year CVD risk using the Atherosclerotic Cardiovascular Disease (ASCVD) risk equation, and reported observed CVD event rates during a median 4.7-year follow-up.ResultsOverall, 74.4% (14 213/19 114) were 'pre-2017 hypertensive'; an additional 12.3% (2354/19 114) were 'reclassified hypertensive' by the AHA/ACC-2017 guideline. Of those 'reclassified hypertensive', the majority (94.5%) met criteria for antihypertensive treatment although 29% had no other traditional CVD risk factors other than age. Further, a relatively lower mean 10-year predicted CVD risk (18% versus 26%, P < 0.001) and lower CVD rates (8.9 versus 12.1/1000 person-years, P = 0.01) were observed in 'reclassified hypertensive' compared with 'pre-2017 hypertensive'. Compared with 'normotensive', a hazard ratio (95% confidence interval) for CVD events of 1.60 (1.26-2.02) for 'pre-2017 hypertensive' and 1.26 (0.93-1.71) for 'reclassified hypertensive' was observed.ConclusionApplying current CVD risk calculators in the elderly 'reclassified hypertensive', as a result of shifting the BP threshold lower, increases eligibility for antihypertensive treatment but documented CVD rates remain lower than hypertensive patients defined by pre2017 BP thresholds.

Project description:ImportanceLittle is known regarding the durability of clinical practice guideline recommendations over time.ObjectiveTo characterize variations in the durability of class I ("procedure/treatment should be performed/administered") American College of Cardiology/American Heart Association (ACC/AHA) guideline recommendations.Design, setting, and participantsTextual analysis by 4 independent reviewers of 11 guidelines published between 1998 and 2007 and revised between 2006 and 2013.Main outcomes and measuresWe abstracted all class I recommendations from the first of the 2 most recent versions of each guideline and identified corresponding recommendations in the subsequent version. We classified recommendations replaced by less determinate or contrary recommendations as having been downgraded or reversed; we classified recommendations for which no corresponding item could be identified as having been omitted. We tested for differences in the durability of recommendations according to guideline topic and underlying level of evidence using bivariable hypothesis tests and conditional logistic regression.ResultsOf 619 index recommendations, 495 (80.0%; 95% CI, 76.6%-83.1%) were retained in the subsequent guideline version, 57 (9.2%; 95% CI, 7.0%-11.8%) were downgraded or reversed, and 67 (10.8%; 95% CI, 8.4%-13.3%) were omitted. The percentage of recommendations retained varied across guidelines from 15.4% (95% CI, 1.9%-45.4%) to 94.1% (95% CI, 80.3%-99.3%; P < .001). Among recommendations with available information on level of evidence, 90.5% (95% CI, 83.2%-95.3%) of recommendations supported by multiple randomized studies were retained, vs 81.0% (95% CI, 74.8%-86.3%) of recommendations supported by 1 randomized trial or observational data and 73.7% (95% CI, 65.8%-80.5%) of recommendations supported by opinion (P = .001). After accounting for guideline-level factors, the probability of being downgraded, reversed, or omitted was greater for recommendations based on opinion (odds ratio, 3.14; 95% CI, 1.69-5.85; P < .001) or on 1 trial or observational data (odds ratio, 3.49; 95% CI, 1.45-8.41; P = .005) vs recommendations based on multiple trials.Conclusions and relevanceThe durability of class I cardiology guideline recommendations for procedures and treatments promulgated by the ACC/AHA varied across individual guidelines and levels of evidence. Downgrades, reversals, and omissions were most common among recommendations not supported by multiple randomized studies.

Project description:Background Impaired endothelial function is thought to contribute to the increased cardiovascular risk associated with above-normal blood pressure (BP). However, the association between endothelial function and BP classified by 2017 American College of Cardiology/American Heart Association guidelines is unknown. Our objective was to determine if endothelial function decreases in midlife/older adults across the 2017 American College of Cardiology/American Heart Association guidelines BP classifications and identify associated mechanisms of action. Methods and Results A retrospective analysis of endothelial function (brachial artery flow-mediated dilation) from 988 midlife/older adults (aged 50+ years) stratified by BP status (normal BP; elevated BP; stage 1 hypertension; stage 2 hypertension) was performed. Endothelium-independent dilation (sublingual nitroglycerin), reactive oxygen species-mediated suppression of endothelial function (∆brachial artery flow-mediated dilation with vitamin C infusion), and endothelial cell and plasma markers of oxidative stress and inflammation were assessed in subgroups. Compared with normal BP (n=411), brachial artery flow-mediated dilation was 12% (P=0.04), 15% (P<0.01) and 20% (P<0.01) lower with elevated BP (n=173), stage 1 hypertension (n=248) and stage 2 hypertension (n=156), respectively, whereas endothelium-independent dilation did not differ (P=0.14). Vitamin C infusion increased brachial artery flow-mediated dilation in those with above-normal BP (P≤0.02) but not normal BP (P=0.11). Endothelial cell p47phox (P<0.01), a marker of superoxide/reactive oxygen species-generating nicotinamide adenine dinucleotide phosphate oxidase, and circulating interleukin-6 concentrations (P=0.01) were higher in individuals with above-normal BP. Conclusions Vascular endothelial function is progressively impaired with increasing BP in otherwise healthy adults classified by 2017 American College of Cardiology/American Heart Association guidelines. Impaired endothelial function with above-normal BP is mediated by excessive reactive oxygen species signaling associated with increased endothelial expression of nicotinamide adenine dinucleotide phosphate oxidase and circulating interleukin-6.

Project description:Background Clinical implications of change in the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guideline on the diagnosis and management of hypertension, compared with recommendations by 2014 expert panel and Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7), are not known. Methods and Results Using data from the NCDR (National Cardiovascular Data Registry) PINNACLE (Practice Innovation and Clinical Excellence) Registry (January 2013-Decemver 2016), we compared the proportion and clinical characteristics of patients seen in cardiology practices diagnosed with hypertension, recommended antihypertensive treatment, and achieving blood pressure (BP) goals per each guideline document. In addition, we evaluated the proportion of patients at the level of practices meeting BP targets defined by each guideline. Of 6 042 630 patients evaluated, 5 027 961 (83.2%) were diagnosed with hypertension per the 2017 ACC/AHA guideline, compared with 4 521 272 (74.8%) per the 2014 panel and 4 545 976 (75.2%) per JNC7. The largest increase in hypertension prevalence was seen in younger ages, women, and those with lower cardiovascular risk. Antihypertensive medication was recommended to 70.6% of patients per the ACC/AHA guideline compared with 61.8% and 65.9% per the 2014 panel and JNC7, respectively. Among those on antihypertensive agents, 41.2% achieved BP targets per the ACC/AHA guideline, compared with 79.4% per the 2014 panel and 64.3% per JNC7. Lower proportions of women, non-White (Black and "other") races, and those at higher cardiovascular risk achieved BP goals. Median practice-level proportion of patients meeting BP targets per the 2014 panel but not the ACC/AHA guideline was 37.8% (interquartile range, 34.8%-40.7%) and per JNC7 but not the ACC/AHA guideline was 22.9% (interquartile range, 19.8%-25.9%). Conclusions Following publication of the 2017 guideline, significantly more people, particularly younger people and those with lower cardiovascular risk, will be diagnosed with hypertension and need antihypertensive treatment compared with previous recommendations. Significant practice-level variation in BP control also exists. Efforts are needed to improve guideline-concordant hypertension management in an effort to improve outcomes.
