Background:
The ratio of triglycerides (TG) to high-density lipoprotein cholesterol (HDL-C) bears a relation with poor outcomes of acute ischemic stroke (AIS), but the impact of serum TG/HDL-C level on post-stroke cognitive impairment (PSCI) remains unknown. We conducted this prospective study to explore the association between TG/HDL-C and PSCI.
Methods:
Consecutive AIS patients from the Stroke Units of our hospital were prospectively enrolled between July 1, 2020, and June 30, 2021. Blood samples were collected within 24 h after admission. Cognition function was evaluated by the Montreal Cognitive Assessment (MoCA) at 3 months after stroke. We used logistic regression analyses to explore the relationship between TG/HDL-C and PSCI, and then used a receiver operating characteristic (ROC) analysis to assess the ability of acute TG/HDL-C for predicting PSCI.
Results:
A total of 227 AIS patients were recruited. Compared with patients without PSCI, those with PSCI had a higher level of TG/HDL-C at admission (P < 0.01). The multivariate logistic regression analyses showed that TG/HDL-C level was independently associated with PSCI (P < 0.01). The area under the curve of the ROC for TG/HDL-C as predictor of PSCI was 0.701 (95%CI 0.635-0.768). The optimal cutoff value of TG/HDL-C to indicate PSCI was 1.564, which gave a sensitivity of 55.2% and specificity of 80.6%.
Conclusions:
Our study demonstrated that a higher level of TG/HDL-C at the acute phase of ischemic stroke predicted the presence of PSCI at 3 months after 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...
