Association of life’s essential 8 score with risk of all-cause and cardiovascular disease-related mortality in individuals with hypertension

Abstract

Abstract Background The American Heart Association (AHA) recently defined a new concept of cardiovascular health-Life’s Essential 8 (LE8). We sought to examine whether LE8 score is associated with a risk of all-cause and cardiovascular disease (CVD)-related mortality in individuals with hypertension. Methods This longitudinal study analyzed data from the National Health and Nutrition Examination Survey from 2007 to 2018 in people 20 years or older with hypertension. LE8 score (range 0-100) was measured according to the AHA definition and divided into unweighted tertiles into groups T1 (< 50.00), T2 (50.00-61.25), and T3 (≥ 61.25). Primary outcomes included all-cause mortality and CVD-specific mortality. Results A total of 15,318 individuals with hypertension were included in this study, with a mean ± standard error age of 55.06 ± 0.25 years. During the median follow-up period of 76 months, 2525 all-cause mortality occurred, of which 806 were due to CVD. Compared with participants with hypertension in the T1 group, those in T2 and T3 respectively had 28% (adjusted HR = 0.72, 95% CI 0.63–0.83, P < 0.001) and 39% (adjusted HR = 0.61, 95% CI 0.52–0.72, P < 0.001) lower risk of all-cause mortality, the T2 and T3 groups were associated with 32% (adjusted HR = 0.68, 95% CI 0.53–0.88, P = 0.003) and 36% (adjusted HR = 0.64, 95% CI 0.49–0.84, P = 0.001) reduced risk of CVD mortality separately. Conclusions A higher LE8 score is associated with a lower risk of all-cause mortality and CVD mortality, and the higher LE8 score can be maintained in the clinic to improve prognosis by modifying the diet and lifestyle habits of individuals with hypertension.
