Abstract Objective The objective of this study was to investigate the relationship between lipoprotein (a) (Lp(a)), triglyceride/high‐density lipoprotein cholesterol (TG/HDL‐C), and the stability of carotid atherosclerotic plaque in patients with acute ischemic stroke. Methods A total of 142 patients with acute ischemic stroke were selected and divided into group A (59 cases of stable plaque formation) and group B (83 cases of unstable plaque formation) according to the characteristics of carotid artery plaque formation detected by carotid color Doppler ultrasound. The serum Lp(a), lipid metabolism indexes, peripheral blood routine indexes, and related serum inflammatory factors indexes were compared between the two groups. Receiver operating characteristic curve and multivariate logistic regression model were used to analyze the relationship between each index and the formation of carotid unstable plaque. Results There were no significant differences in serum total cholesterol (TC), HDL‐C, and low‐density lipoprotein cholesterol (LDL‐C) between groups A and B (p > .05). The values of Lp(a), TG, and TG/HDL‐C in group B were higher than those in group A, and the differences were statistically significant (p .05). The values of Lp(a), TG, and TG/HDL‐C in group B were higher than those in group A, and the differences were statistically significant (p .05). The results of logistic regression model showed that the increase of Lp(a), TG/HDL‐C, HBA1C, Lp‐PLA2, CRP, CysC, Hcy, and NLR could increase the risk of carotid artery unstable plaque in patients with ischemic stroke (p < .05). Conclusion Lp(a) and TG/HDL‐C have certain value in evaluating the stability of carotid atherosclerotic plaque in patients with acute ischemic stroke, and the increased levels of LP (a) and TG/HDL‐C will significantly increase the risk of carotid unstable plaque in patients.
