Prognostic Role of Neutrophil to High-Density Lipoprotein Cholesterol Ratio for All-Cause and Cardiovascular Mortality in the General Population. | LitMetric

AI Article Synopsis

  • The study examines the relationship between neutrophil counts to high-density lipoprotein cholesterol ratio (NHR) and mortality rates in adults, using data from the National Health and Nutrition Examination Survey (NHANES) covering 34,335 participants from 1999 to 2014.
  • Results showed that individuals in the highest NHR tertile had a 29% increased risk of all-cause mortality and a higher risk of cardiovascular mortality compared to those in the lowest tertile.
  • The findings suggest that higher NHR is a strong predictor of both all-cause and cardiovascular mortality, indicating its potential value in assessing health risks in the general population.

Article Abstract

Background: Neutrophil counts to high-density lipoprotein cholesterol ratio (NHR), a composite marker of inflammation and lipid metabolism, has been considered as a predictor of clinical outcomes in patients with acute ischemic stroke and acute myocardial infarction. However, the predictive value of NHR for all-cause and cardiovascular mortality in the general population remains unclear.

Methods: Our study population comprised 34,335 adults in the United States obtained from the National Health and Nutrition Examination Survey (NHANES) (1999-2014) and were grouped in accordance with tertiles of NHR. Kaplan-Meier curves and log-rank test were used to investigate the differences of survival among groups. Multivariate Cox regression, restricted cubic spline analysis, and subgroup analysis were applied to explore the relationship of NHR with all-cause and cardiovascular mortality.

Results: The mean age of the study cohort was 49.6 ± 18.2 years and 48.4% were men. During a median follow-up of 82 months, 4,310 (12.6%) all-cause deaths and 754 (2.2%) cardiovascular deaths occurred. In a fully-adjusted Cox regression model, participants in the highest tertile had 29% higher hazard of all-cause mortality than those in the lowest tertile [hazard ratio (HR) = 1.29, 95% : 1.19-1.41]. For cardiovascular mortality, the continuously increased HR with 95% s among participants in the middle and highest tertile were 1.30 (1.06-1.59) and 1.44 (1.17-1.78), respectively. The restricted cubic spline curve indicated that NHR had a non-linear association with all-cause mortality ( for non-linearity < 0.001) and a linear association with cardiovascular mortality ( for non-linearity = 0.553).

Conclusion: Increased NHR was a strong and independent predictor of all-cause and cardiovascular mortality in the general population.
