Among adults with prehypertension, elevated remnant cholesterol was independently and linearly associated with higher risk of progression to incident hypertension, and genetic evidence supported a potential role of RC in hypertension-related traits.
About 31% of adults with prehypertension in the CHARLS cohort developed incident hypertension over 4 years of follow-up.
Higher remnant cholesterol (RC) was independently associated with increased odds of incident hypertension, on a continuous scale.
Participants in the highest RC quartile had markedly higher odds and absolute incidence of hypertension than those in the lowest quartile.
The dose-response relationship between RC and incident hypertension was linear.
The RC–hypertension association was stronger in certain subgroups.
Mendelian randomization analyses supported a positive genetic association between elevated RC and hypertension-related traits.
The authors conclude that RC, calculable from routine lipid profiles, may complement hypertension risk assessment and targeted blood pressure monitoring in people with prehypertension.
This study looked at whether a blood measure called remnant cholesterol, the cholesterol carried in triglyceride-rich particles left over after fat metabolism, is linked to the progression from prehypertension (slightly elevated blood pressure) to full hypertension. Researchers followed 2,858 Chinese adults with prehypertension for four years. During that time, 891 developed hypertension. People with higher remnant cholesterol were more likely to develop hypertension. Each 1 mg/dL increase was linked to 2% higher odds, and those in the highest quartile had 67% higher odds than those in the lowest, an 11.86 percentage-point difference in hypertension incidence. The relationship was linear, with no threshold. It appeared stronger in older adults, non-smokers, people of normal weight, and those without depressive symptoms. A genetic analysis (Mendelian randomization), which helps test whether a link may be causal, also supported a positive association between remnant cholesterol and hypertension-related traits. This research suggests remnant cholesterol, which can be calculated from a standard cholesterol test, could help identify people with prehypertension who may be at higher risk of developing hypertension and might benefit from closer blood pressure monitoring. Because the main data are observational and from one population, the findings show an association and do not by themselves prove that lowering remnant cholesterol would prevent hypertension.
