BackgroundThe low-density lipoprotein cholesterol/high-density lipoprotein cholesterol (LDL-C/HDL-C) ratio has been recognized as a strong risk predictor of cardiovascular diseases. However, the association between the LDL-C/HDL-C ratio and the prognosis of acute intracranial hemorrhage (ICH) is unclear. Thus, we prospectively investigated whether a low LDL-C/HDL-C ratio could predict all-cause mortality and whether LDL-C/HDL-C ratio is superior to traditional lipid profiles in predicting mortality among Chinese patients with acute ICH.MethodsA prospective cohort study of 356 patients with acute ICH was conducted, and the mean follow-up time point was 80.4 days. Participants were divided into four categories based on LDL-C/HDL-C ratio quartiles. Three-month outcomes were evaluated by in-person or telephone interviews with patients or their family members. The end point was three-month mortality from all causes.ResultsForty-seven deaths from all causes were documented. The multivariate analysis found that LDL-C/HDL-C ratio [hazard ratio (HR) = 0.49, p = 0.008] and LDL-C (HR = 0.27, p = 0.044) were significantly associated with all-cause mortality. The Kaplan-Meier curves show that patients in the lowest quartiles had the highest cumulative incidence rates (log-rank p = 0.027). After adjusting for covariates, a low LDL-C/HDL-C ratio was associated with a 3.55-fold increase in the risk of all-cause mortality (HR, 3.55 [95% confidence interval, 1.04-12.14]; P-trend = 0.011) when the highest and lowest quartiles were compared. The C-statistic of the LDL-C/HDL-C ratio was significantly larger than other traditional lipid profiles (all p < 0.05).ConclusionsA low LDL-C/HDL-C ratio was independently associated with an increased risk of all-cause mortality at three months in patients with ICH. Moreover, the LDL-C/HDL-C ratio appeared to be a best lipid predictor of all-cause mortality than traditional lipid profiles.
