Insights
Lower high-density lipoprotein cholesterol (HDL-C) and triglyceride levels are linked to worse outcomes in ischemic stroke patients receiving IV thrombolysis. These lipid levels may offer protective benefits post-stroke.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Biochemistry
Background:
- Lipid profiles, including low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides, play a role in cardiovascular health.
- The impact of specific lipid parameters on outcomes following acute ischemic stroke treated with intravenous thrombolysis requires further elucidation.
Purpose of the Study:
- To investigate the association between lipid concentrations (LDL-C, HDL-C, triglycerides) and patient outcomes after ischemic stroke treated with IV thrombolysis.
- To determine if low HDL-C or triglyceride levels, rather than LDL-C, are associated with poorer outcomes.
Main Methods:
- An observational, multicenter, post hoc analysis was conducted using prospectively collected data from stroke thrombolysis registries.
- Two statistical models were employed to address collinearity between total cholesterol (TC) and LDL-C, one using TC and the other using LDL-C.
Main Results:
- Lower serum HDL-C and triglyceride levels were independently associated with increased 3-month mortality in ischemic stroke patients.
- Higher HDL-C levels were associated with an excellent outcome (modified Rankin Scale score 0-1).
- Lipid concentrations were not independently associated with symptomatic intracranial hemorrhage (ICH).
Conclusions:
- Reduced HDL-C and triglyceride levels are independently linked to higher mortality rates following acute ischemic stroke.
- These findings suggest a potential protective role for HDL-C and triglycerides in the acute phase of ischemic stroke.
- The observed associations may be influenced by baseline comorbidities, nutritional status, or a direct physiological effect of these lipids.
Objective:
To determine whether low low-density lipoprotein cholesterol (LDL-C) but not high-density lipoprotein cholesterol (HDL-C) and triglyceride concentrations are associated with worse outcome in a large cohort of ischemic stroke patients treated with IV thrombolysis.
Methods:
Observational multicenter post hoc analysis of prospectively collected data in stroke thrombolysis registries. Because of collinearity between total cholesterol (TC) and LDL-C, we used 2 different models with TC (model 1) and with LDL-C (model 2).
Results:
Of the 2,485 consecutive patients, 1,847 (74%) had detailed lipid profiles available. Independent predictors of 3-month mortality were lower serum HDL-C (adjusted odds ratio [(adj)OR] 0.531, 95% confidence interval [CI] 0.321-0.877 in model 1; (adj)OR 0.570, 95% CI 0.348-0.933 in model 2), lower serum triglyceride levels ((adj)OR 0.549, 95% CI 0.341-0.883 in model 1; (adj)OR 0.560, 95% CI 0.353-0.888 in model 2), symptomatic ICH, and increasing NIH Stroke Scale score, age, C-reactive protein, and serum creatinine. TC, LDL-C, HDL-C, and triglycerides were not independently associated with symptomatic ICH. Increased HDL-C was associated with an excellent outcome (modified Rankin Scale score 0-1) in model 1 ((adj)OR 1.390, 95% CI 1.040-1.860).
Conclusion:
Lower HDL-C and triglycerides were independently associated with mortality. These findings were not due to an association of lipid concentrations with symptomatic ICH and may reflect differences in baseline comorbidities, nutritional state, or a protective effect of triglycerides and HDL-C on mortality following acute ischemic stroke.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
