Implications of the 2017 American College of Cardiology/American Heart Association Hypertension Guideline in a Modern Primary Prevention Multi-Ethnic Prospective Cohort (Multi-Ethnic Study of Atherosclerosis).

ABSTRACT: The American College of Physicians and the American Academy of Family Physician did not endorse the 2017 American College of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines citing multiple concerns. We assessed the increase in antihypertensive medication eligibility introduced by the 2017 hypertension guideline and the risk profile of those newly eligible for blood pressure medication using participants from the MultiEthnic Study of Atherosclerosis. The antihypertensive medication eligibility criteria of the Joint National Commission (JNC) VII, JNC VIII, and the 2017 ACC/AHA hypertension guidelines were applied to the cohort and the risk profile of those newly eligible was compared with those ineligible for antihypertensive medication under the 2017 ACC/AHA guidelines using Kaplan-Meier and Cox proportional hazard analysis. The new guideline increased antihypertensive medication eligibility by 46.8% and 96.7% compared with the JNC VII and JNC VIII guideline respectively. The newly eligible group did not have an increased risk of incident atherosclerotic cardiovascular disease, heart failure, or death compared with those ineligible (HR [95%CI]: 1.26 [0.96 to 1.65], p?=?0.10; 0.75 [0.45 to 1.26], p?=?0.27; 1.06 [-0.84 to 1.36], p?=?0.62, respectively) after adjusting for age, gender, and race. The 2017 ACC/AHA hypertension guidelines extend antihypertensive medication to a substantial number of individuals, although the risk profile of the newly eligible group appears similar to those ineligible for antihypertensive medication after adjusting for non-modifiable risk factors.

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: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 recommends reduced systolic/diastolic blood pressure (SBP/DBP) cutoffs to define hypertension (i.e., by changing these from ?140/90 to ?130/80?mmHg), including new recommendations about indications and goals of antihypertensive treatment. This study reported the differences in age-adjusted prevalence and treatment status of hypertension according to race among US adults per the 2017 ACC/AHA guideline. The National Health and Nutrition Examination Survey 2011-16 data was analyzed. The main outcomes were age-adjusted prevalence and treatment status of hypertension among adults aged ?20?years. After prevalence estimation, other proportions were obtained. The analysis included 16,103 adults (mean age: 47.6?years, 51.8% women). The age-adjusted proportions of adults with hypertension (59.0%, 95% confidence interval [CI]: 57.4%-60.6%), treatment-eligible for hypertension (49.3%, 95% CI: 47.7%-50.8%), and unmet treatment goals (63.8%, 95% CI: 60.0%-67.5%) among the treated were highest among non-Hispanic blacks. A large proportion of Mexican-Americans (46.5%, 95% CI: 42.0%-51.0%) and people of other races/ethnicities (49.3%, 95% CI: 45.5%-53.0%) were not receiving treatment despite having indication. Non-Hispanic blacks also had the highest prevalence of stage 2 hypertension. Among all races, prevalence, treatment-eligibility, and unmet treatment goals were higher among people with older age, male gender, diabetes, higher body weight, and higher cardiovascular disease risk while the majority of younger, lower/normal body weight, or non-diabetic people were untreated despite being eligible for treatment. The prevalence, treatment-eligibility, and unmet goals were substantially higher among non-Hispanic blacks. Moreover, disparities exist in treatment where Mexican-Americans and people of 'other races/ethnicities' were largely untreated despite having indication.

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.

Project description:BACKGROUND:The impact of replacing the National Cholesterol Education Program (NCEP)/Adult Treatment Program (ATP) III cholesterol guidelines with the new 2013 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines for primary prevention of cardiovascular disease is unclear. METHODS:We used risk factor and 10-year clinical event rate data from MESA, combined with estimates of efficacy of moderate and high-intensity statin therapy from meta-analyses of statin primary prevention trials to estimate (a) the change in number of subjects eligible for drug therapy and (2) the anticipated reduction in atherosclerotic cardiovascular disease (ASCVD) events and increment in type 2 diabetes mellitus (T2DM) associated with the change in cholesterol guidelines. RESULTS:Of the 6,814 MESA participants, 5,437 were not on statins at baseline and had complete data for analysis (mean age 61.4±10.3). Using the NCEP/ATP III guidelines, 1,334 (24.5%) would have been eligible for statin therapy compared with 3,015 (55.5%) under the new ACC/AHA guidelines. Among the subset of newly eligible, 127/1,742 (7.3%) had an ASCVD event during 10years of follow-up. Assuming 10years of moderate-intensity statin therapy, the estimated absolute reduction in ASCVD events for the newly eligible group was 2.06% (number needed to treat [NNT] 48.6) and the estimated absolute increase in T2DM was 0.90% (number needed to harm [NNH] 110.7). Assuming 10years of high-intensity statin therapy, the corresponding estimates for reductions in ASCVD and increases in T2DM were as follows: ASCVD 2.70% (NNT 37.5) and T2DM 2.60% (NNH 38.6). The estimated effects of moderate-intensity statins on 10-year risk for ASCVD and T2DM in participants eligible for statins under the NCEP/ATP III were as follows: 3.20% (NNT 31.5) and 1.06% (NNH 94.2), respectively. CONCLUSION:Substituting the NCEP/ATP III cholesterol guidelines with the 2013 ACC/AHA cholesterol guidelines in MESA more than doubled the number of participants eligible for statin therapy. If the new ACC/AHA cholesterol guidelines are adopted and extend the primary prevention population eligible for treatment, the risk-benefit profile is much better for moderate-intensity than high-intensity statin treatment.

Project description:BackgroundOver 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.MethodsUS 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).ResultsOver 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).ConclusionsAchieving 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:OBJECTIVE:The American College of Cardiology and American Heart Association have issued guidelines indicating that the contribution of apolipoprotein B-100 (ApoB) to cardiovascular risk assessment remains uncertain. The present analysis evaluates whether lipoprotein particle measures convey risk of coronary heart disease (CHD) in 4679 Multi-Ethnic Study of Atherosclerosis (MESA) participants. APPROACH AND RESULTS:Cox regression analysis was performed to determine associations between lipids or lipoproteins and primary CHD events. After adjustment for nonlipid variables, lipoprotein particle levels in fourth quartiles were found to convey significantly greater risk of incident CHD when compared to first quartile levels (hazard ratio [HR]; 95% confidence interval [CI]): ApoB (HR, 1.84; 95% CI, 1.25-2.69), ApoB/ApoA-I (HR, 1.91; 95% CI, 1.32-2.76), total low-density lipoprotein-particles (LDL-P; HR, 1.77; 95% CI, 1.21-2.58), and the LDL-P/HDL-P (high-density lipoprotein-P) ratio (HR, 2.28; 95% CI, 1.54-3.37). Associations between lipoprotein particle measures and CHD were attenuated after adjustment for standard lipid panel variables. Using the American Heart Association/American College of Cardiology risk calculator as a baseline model for CHD risk assessment, significant net reclassification improvement scores were found for ApoB/ApoA-I (0.18; P=0.007) and LDL-P/high-density lipoprotein-P (0.15; P<0.001). C-statistics revealed no significant increase in CHD event discrimination for any lipoprotein measure. CONCLUSIONS:Lipoprotein particle measures ApoB/ApoA-I and LDL-P/high-density lipoprotein-P marginally improved net reclassification improvement scores, but null findings for corresponding c-statistic are not supportive of lipoprotein testing. The attenuated associations of lipoprotein particle measures with CHD after the adjustment for lipids indicate that their measurement does not detect risk that is unaccounted for by the standard lipid panel. However, the possibility that lipoprotein measures may identify CHD risk in a subpopulation of individuals with normal cholesterol, but elevated lipoprotein particle numbers cannot be ruled out.

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.
