BACKGROUND: To investigate the potential benefits of inpatient statin therapy on mortality of acute stroke patients with very low admission low-density lipoprotein cholesterol (LDL-C) level (<1.81 mmol/L). METHODS: The acute stroke patients with admission LDL-C level less than 1.81 mmol/L were enrolled from the China National Stroke Registry. The patients were divided into statin group and non-statin group during hospitalization. The association between statin therapy and mortality of participants in 1 year was analyzed by multivariable binary logistic regression models. RESULTS: A total of 1018 patients were enrolled, and the cumulative mortality rate was 10.1% at 3 months, 13.1% at 6 months, and 15.9 % at 1 year. The all-cause mortality rate in statin group was significantly lower than that in non-statin group (3.6% versus 13.7% at 3 months, P < .001; 6.2% versus 16.9% at 6 months, P < .001; 8.4% versus 20% at 1 year, P < .001). The logistic analyses showed that statin therapy during hospitalization was independently associated with decreased mortality at 3 months (odds ratio [OR], .35; 95% confidence interval [CI], .18-.67), at 6 months (OR, .42; 95% CI, .25-.73) and at 1 year (OR, .47; 95% CI, .29-.76). CONCLUSIONS: Statin use during hospitalization could decrease mortality of acute ischemic stroke patients with very low admission LDL-C.
