Insights
Elevated remnant cholesterol levels are linked to poorer blood pressure control in the general US population. Managing remnant cholesterol may improve hypertension management, especially in high-risk individuals.
Area of Science:
- Cardiovascular Medicine
- Lipid Metabolism
- Public Health
Background:
- High blood pressure is a significant risk factor for cardiovascular and renal diseases.
- Lipid metabolism disorders, including remnant cholesterol, may influence blood pressure via mechanisms like endothelial inflammation.
- Remnant cholesterol, derived from triglyceride-rich lipoproteins, is implicated in atherosclerosis and metabolic disorders.
Purpose of the Study:
- To investigate the association between remnant cholesterol and blood pressure control.
- To analyze this relationship within the general US population.
Main Methods:
- Utilized data from 3915 participants with self-reported hypertension from the NHANES (2007-2018).
- Collected demographic, behavioral, blood pressure, and blood sample data.
- Estimated remnant cholesterol and defined hypertension control (systolic BP <140 mmHg and diastolic BP <90 mmHg).
Main Results:
- The study included a mean age of 56.98 years, with 51.34% females.
- 2650 participants (67.94%) achieved blood pressure control.
- Multivariate logistic regression revealed a significant inverse association between remnant cholesterol and blood pressure control (e.g., OR=0.60, 95% CI: 0.46-0.78 after full adjustment).
Conclusions:
- Remnant cholesterol is significantly associated with blood pressure control in the US general population.
- Targeting remnant cholesterol through lifestyle changes or lipid-lowering therapies could be a strategy to improve hypertension management.
- Further research may elucidate specific interventions for high-risk patients.
Background:
High blood pressure is a major risk factor for cardiovascular and renal diseases, and lipid metabolism disorders may affect blood pressure through mechanisms such as endothelial inflammation. Remnant cholesterol, a key component of triglyceride-rich lipoproteins, has been recognized as a causal factor for atherosclerosis and metabolic disorders. This study aims to investigate the relationship of remnant cholesterol with blood pressure control in the general US population.
Methods:
A total of 3915 participants with self-reported hypertension from NHANES from 2007 to 2018 were included in this study. Demographic and behavior parameters, blood pressure, and blood samples were conducted. Remnant cholesterol was estimated as total cholesterol minus low-density lipoprotein cholesterol minus high-density lipoprotein cholesterol. Control of hypertension was defined as systolic blood pressure less than 140 mmHg and diastolic blood pressure less than 90 mmHg in participants with hypertension.
Results:
The mean age was 56.98 ± 0.28 years, and 2021 (weighted percentage 51.34%) were female. Among all participants, 2650 participants had their blood pressure well controlled. In multivariate logistic regression, the associations between remnant cholesterol and blood pressure control were statistically significant after adjusting age, sex, race/ethnicity, education level, poverty income ratio, smoking and drinking status, metabolic equivalent, HbA1c, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (Model 1: OR=0.74, 95% CI: 0.57-0.95; Model 2: OR=0.72, 95% CI: 0.55-0.94; Model 3: OR=0.73, 95% CI: 0.56-0.93; Model 4: OR=0.60, 95% CI: 0.46-0.78). The subgroup analysis revealed generally consistent associations with the main results.
Conclusion:
Remnant cholesterol is associated with blood pressure control. Targeting remnant cholesterol through lifestyle modifications or lipid-lowering therapies may improve blood pressure control in high-risk patients.
