Objective To investigate the correlation between microembolic signal (MES) and immune inflammation in patients with acute ischemic stroke. Methods The consecutive patients with acute ischemic stroke were enroled. According to the results of MES, they were divided into either a positive group or a negative group. The Immune inflammatory indexes, demographics, and baseline clinical data in both groups were compared. Multivariate logistic regression analysis was used to analyze the independent influencing factors of MES in acute ischemic stroke. Results A total of 237 patients were enroled, including 52 in the MES positive group and 185 in the MES negative group. There were significant differences in the levels of triglyceride (2. 130 ± 0. 933 mmol/L vs. 1. 811 ± 0. 962 mmol/L; t = 2. 126, P = 0. 035), plasma fibrinogen (2. 946 ± 0. 255 g/L vs. 2. 833 ± 0. 322 g/L; t = 2. 332, P = 0. 021 ), Lp-PLA2 level ( 288. 265 ± 27. 855 μg/L vs. 261. 652 ± 29. 961 μg/L; t = 2. 897, P = 0. 004 ), as wel as the proportions of CD4 + CD25high Treg (8. 695% ± 1. 461% vs. 9. 445% ± 1. 397% ; t = 3. 386, P = 0. 001), artery stenosis ≥70% (21. 15% vs. 5. 41% ; χ2 = 10. 592, P = 0. 001 ) and smal arterial occlusive stroke (9. 62% vs. 23. 24% ; χ2 = 4.667, P = 0. 031) between the MES positive group and the MES negative group. Multivariate logistic regression analysis showed that the increased plasma fibrinogen level (odds ratio [OR] 3. 257, 95%confidence interval [CI] 1. 124 - 9. 438; P = 0. 030), artery stenosis ≥ 70% (OR 3. 585, 95% CI 1. 394 -9. 219; P = 0. 008), and the decreased ratio of Treg (OR 3. 801, 95% CI 1. 190 - 12. 148; P = 0. 024) were the independent risk factors for positive MES, and smal arterial occlusive stroke was its independent protective factor (OR 0. 244, 95% CI 0. 072 - 0. 829; P = 0. 024). Conclusions MES may be associated with immune inflammation. The relationship between stroke and immune inflammation should be taken seriously.
