Modifiable factors and 10-year and lifetime cardiovascular disease risk in adults with new-onset hypertension: insights from the Kailuan cohort.

backgroundPreventing cardiovascular disease (CVD) in adults with hypertension is essential, but it remains uncertain whether optimizing modifiable factors can eliminate the excess CVD risk associated with new-onset hypertension.

methodsIn this prospective cohort study, 29,597 adults with new-onset hypertension and no prior CVD (from 2006-2016 surveys) were each matched by age and sex to a normotensive control. Eight modifiable factors were assessed using the American Heart Association's Life's Essential 8 algorithm. We followed participants for incident CVD until December 2020, estimating 10-year and lifetime (age 25-95) CVD risks using the Fine-Gray competing risks model.

resultsOver a median follow-up of 9.81 years, adults with new-onset hypertension had higher 10-year (8.97% vs. 6.31%) and lifetime CVD risks (45.55% vs. 34.98%) compared to normotensive controls. After adjusting for age, sex, and other unmodifiable factors, each additional favorable factor was associated with a stepwise reduction in CVD risk (P-trend < 0.05). Hypertensive participants with four or more favorable factors had a 17% lower 10-year CVD risk (HR 0.83; 95% CI 0.72-0.97) and a similar lifetime CVD risk (HR 0.90; 95% CI 0.78-1.05) compared to normotensive controls. Notably, the protective effect was weaker among those with early-onset (before age 45) hypertension than those with later-onset (age ≥ 60) hypertension (P-interaction < 0.05).

conclusionsIn adults with new-onset hypertension, maintaining four or more modifiable factors at favorable levels was associated with a CVD risk comparable to that of normotensive individuals. However, young hypertensive adults may require more aggressive interventions to mitigate CVD risk.
