Association between blood pressure classification defined by the 2017 ACC/AHA guidelines and coronary artery calcification progression in an asymptomatic adult population.

ABSTRACT:

Aims

Coronary artery calcium score (CACS) is widely used for cardiovascular risk stratification in asymptomatic population. We assessed the association of new blood pressure (BP) classification using the 2017 American College of Cardiology/American Heart Association guidelines with coronary artery calcification (CAC) progression according to age in asymptomatic adults.

Methods and results

Overall, 10 839 asymptomatic Korean adults (23.4% aged ≤45 years) who underwent at least two CACS evaluations for health check-up were enrolled. Participants were categorized by age (≤45 and >45 years) and BP [normal (<120/<80 mmHg, untreated), elevated (120-129/<80 mmHg, untreated), Stage 1 hypertension (untreated BP 130-139/80-89 mmHg) or Stage 2 hypertension (BP ≥140/≥90 mmHg or anti-hypertensive use)] groups. CAC progression was defined as a difference of ≥2.5 between the square root (√) of the baseline and follow-up CACS. During a mean 3.3-year follow-up, the incidence of CAC progression was 13.5% and 36.3% in individuals aged ≤45 and >45 years, respectively. After adjustment for age, sex, diabetes, dyslipidaemia, obesity, current smoking, and baseline CACS, hazard ratios (95% confidence interval) for CAC progression in elevated BP, Stage 1 hypertension, and Stage 2 hypertension compared to normal BP were 1.43 (0.96-2.14) (P = 0.077), 1.64 (1.20-2.23) (P = 0.002), and 2.38 (1.82-3.12) (P < 0.001) in the ≤45 years group and 1.11 (0.95-1.30) (P = 0.179), 1.17 (1.04-1.32) (P = 0.009), and 1.52 (1.39-1.66) (P < 0.001) in the >45 years group, respectively.

Conclusion

Newly defined Stage 1 hypertension is independently associated with CAC progression in asymptomatic adults regardless of age.

Project description:BackgroundHypertension is a significant risk factor for cardiovascular disease (CVD), with hypertension-related deaths increasing annually. While South Korea uses the Korean Society of Hypertension (KSH) guideline of 140/90 mmHg, the American College of Cardiology (ACC) and American Heart Association (AHA) updated their guidelines in 2017 to 130/80 mmHg. This study evaluates the cost-effectiveness of transitioning to the 2017 ACC/AHA guidelines by estimating early treatment impacts and potential CVD risk reduction.MethodsA Markov state-transition simulation model with a 10-year horizon was used to estimate cost-effectiveness, focusing on strengthening target blood pressure. Quality-adjusted life years (QALYs) served as the measure of effectiveness. Cohorts of 10,000 individuals representing South Koreans in their 20s through 80s were compared in scenario analyses from the healthcare system perspective. A 4.5% annual discount rate was applied to costs and effectiveness. Primary outcomes were incremental cost-effectiveness ratio (ICER) and net monetary benefit (NMB). The willingness-to-pay (WTP) threshold was < KRW 30,000,000/QALY gained. Probabilistic sensitivity analyses (PSAs) addressed model input parameter uncertainties.ResultsThe base-case analysis showed an ICER value of KRW 1,328,395/QALY gained across all populations. ICER values increased with age, from - KRW 3,138,071/QALY for 20-year-olds to KRW 16,613,013/QALY for individuals over 80. The 60s age group showed the greatest benefit with an incremental QALY gain of 0.46. All scenarios had ICERs below the WTP threshold, with a PSA probability of 98.0% that strengthening blood pressure classification could be cost-effective.ConclusionsThis economic evaluation found that adopting the 2017 ACC/AHA guidelines may result in early treatment, reduce the potential incidence of CVD events, and be cost-effective across all age groups. The study findings have implications for policymakers deciding whether and when to revise official guidelines regarding target blood pressure levels, considering the impacts on public health and budgetary concerns.

Project description:BackgroundThe 2017 American College of Cardiology/American Heart Association (ACC/AHA) blood pressure (BP) guideline provides updated recommendations for antihypertensive medication initiation and intensification.ObjectivesDetermine the risk for cardiovascular disease (CVD) events among adults recommended and not recommended antihypertensive medication initiation or intensification by the 2017 ACC/AHA BP guideline.MethodsThe authors analyzed data for black and white REGARDS (REasons for Geographic And Racial Differences in Stroke) study participants (age ≥45 years). Systolic BP (SBP) and diastolic BP (DBP) were measured twice at baseline (2003 to 2007) and averaged. Participants not taking (n = 14,039) and taking (n = 15,179) antihypertensive medication were categorized according to their recommendations for antihypertensive medication initiation and intensification by the 2017 ACC/AHA guideline. Overall, 4,094 CVD events (stroke, coronary heart disease, and heart failure) occurred by December 31, 2014.ResultsAmong participants not taking antihypertensive medication, 34.4% were recommended pharmacological antihypertensive treatment initiation. The CVD event rate per 1,000 person-years among participants recommended antihypertensive medication initiation with SBP/DBP ≥140/90 mm Hg was 22.7 (95% confidence interval [CI]: 20.3 to 25.0). Among participants with SBP/DBP 130 to 139/80 to 89 mm Hg, the CVD event rate was 20.5 (95% CI: 18.5 to 22.6) and 3.4 (95% CI: 2.4 to 4.4) for those recommended and not recommended antihypertensive medication initiation, respectively. Among participants taking antihypertensive medication, 62.8% were recommended treatment intensification. The CVD event rate per 1,000 person-years among participants recommended treatment intensification was 33.6 (95% CI: 31.5 to 35.6) and 22.4 (95% CI: 20.8 to 23.9) for those with SBP/DBP ≥140/90 mm Hg and 130 to 139/80 to 89 mm Hg, respectively.ConclusionsImplementing the 2017 ACC/AHA guideline would direct antihypertensive medication initiation and intensification to adults with high CVD risk.

Project description:ImportanceIn the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guideline, the definition of hypertension was lowered from a blood pressure (BP) of greater than or equal to 140/90 to greater than or equal to 130/80 mm Hg. The new diastolic BP threshold of 80 mm Hg was recommended based on expert opinion and changes the definition of isolated diastolic hypertension (IDH).ObjectiveTo compare the prevalence of IDH in the United States, by 2017 ACC/AHA and 2003 Joint National Committee (JNC7) definitions, and to characterize cross-sectional and longitudinal associations of IDH with outcomes.Design, setting, and participantsCross-sectional analyses of the National Health and Nutrition Examination Survey (NHANES 2013-2016) and longitudinal analyses of the Atherosclerosis Risk in Communities (ARIC) Study (baseline 1990-1992, with follow-up through December 31, 2017). Longitudinal results were validated in 2 external cohorts: (1) the NHANES III (1988-1994) and NHANES 1999-2014 and (2) the Give Us a Clue to Cancer and Heart Disease (CLUE) II cohort (baseline 1989).ExposuresIDH, by 2017 ACC/AHA (systolic BP <130 mm Hg, diastolic BP ≥80 mm Hg) and by JNC7 (systolic BP <140 mm Hg, diastolic BP ≥90 mm Hg) definitions.Main outcomes and measuresWeighted estimates for prevalence of IDH in US adults and prevalence of US adults recommended BP pharmacotherapy by the 2017 ACC/AHA guideline based solely on the presence of IDH. Risk of incident atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), and chronic kidney disease (CKD) in the ARIC Study.ResultsThe study population included 9590 adults from the NHANES (mean [SD] baseline age, 49.6 [17.6] years; 5016 women [52.3%]) and 8703 adults from the ARIC Study (mean [SD] baseline age, 56.0 [5.6] years; 4977 women [57.2%]). The estimated prevalence of IDH in the NHANES was 6.5% by the 2017 ACC/AHA definition and 1.3% by the JNC7 definition (absolute difference, 5.2% [95% CI, 4.7%-5.7%]). Among those newly classified as having IDH, an estimated 0.6% (95% CI, 0.5%-0.6%) also met the guideline threshold for antihypertensive therapy. Compared with normotensive ARIC participants, IDH by the 2017 ACC/AHA definition was not significantly associated with incident ASCVD (n = 1386 events; median follow-up, 25.2 years; hazard ratio [HR], 1.06 [95% CI, 0.89-1.26]), HF (n = 1396 events; HR, 0.91 [95% CI, 0.76-1.09]), or CKD (n = 2433 events; HR, 0.98 [95% CI, 0.65-1.11]). Results were also null for cardiovascular mortality in the 2 external cohorts (eg, HRs of IDH by the 2017 ACC/AHA definition were 1.17 [95% CI, 0.87-1.56] in the NHANES [n = 1012 events] and 1.02 [95% CI, 0.92-1.14] in CLUE II [n = 1497 events]).Conclusions and relevanceIn this analysis of US adults, the estimated prevalence of IDH was more common when defined by the 2017 ACC/AHA BP guideline compared with the JNC7 guideline. However, IDH was not significantly associated with increased risk for cardiovascular outcomes.
