  • Preoperative peripheral blood CD4/CD8 ratio in predicting the prognosis of patients with coronary atherosclerotic heart disease after off-pump coronary artery bypass grafting

    ObjectiveTo investigate the role of preoperative peripheral blood CD4/CD8 ratio in predicting the prognosis of patients with coronary atherosclerotic heart disease (CAD) after off-pump coronary artery bypass grafting (OPCABG).MethodsA total of 118 patients with CAD who underwent OPCABG in our hospital from September 2016 to April 2017 were included in the study, including 82 males and 36 females aged 62.74±4.50 years. The primary end point was the incidence of major adverse cardiovascular events (MACE). Patients were divided into a high CD4/CD8 group (≥1.40, 62 patients) and a low CD4/CD8 group (<1.40, 56 patients) according to the results of flow cytometry. The correlation between CD4/CD8 ratio and prognosis of patients after OPCABG and the value of CD4/CD8 ratio for predicting postoperative MACE were evaluated.ResultsMedian duration of follow-up was 23.25 (20.91, 24.70) months, during which 21 patients (17.80%) experienced MACE and 4 patients (3.39%) were lost to follow-up. Kaplan-Meier analysis revealed that high CD4/CD8 group had a significantly higher MACE rate than the low CD4/CD8 group did (log-rank χ2=5.797, P=0.02). The results of adjusted Cox proportional hazards model showed that CD4/CD8 ratio (HR=3.103, 95%CI 1.557-6.187, P<0.01) was an independent risk factor of MACE in patients with CAD after OPCABG. The receiver operating characteristic curve showed that area under curve was 0.778 (95%CI 0.661-0.894, P<0.01), the optimal cut off value was 2.24, the sensitivity was 57.1%, and the specificity was 87.6%.ConclusionPreoperative peripheral blood CD4/CD8 ratio is an independent predictor of MACE after OPCABG in patients with CAD.

  • Intraoperative single branch stent combined with modified bilateral cerebral perfusion for the treatment of type A aortic dissection: A propensity score matching study

    ObjectiveTo explore the clinical efficacy of single-branch intraoperative stent combined with modified bilateral cerebral perfusion in type A aortic dissection. MethodsA retrospective analysis was conducted on the clinical data of patients who underwent surgery for type A aortic dissection at the First Affiliated Hospital of Anhui Medical University from January 2021 to May 2024. Patients were divided into the experimental group (single branch stent combined with modified bilateral cerebral perfusion) and the control group (traditional surgical method, straight stent+unilateral cerebral perfusion) according to the surgical method. Propensity score matching analysis was used to match the two groups of patients with a ratio of 1:1, and the perioperative data and clinical efficacy after matching were compared. ResultsA total of 14 patients were included in the experimental group, including 13 males and 1 female, with an average age of (47.4±16.1) years. There were 56 patients in the control group, including 38 males and 18 females, with an average age of (52.1±11.7) years. After propensity score matching, 14 patients were included in each group. Compared with the control group, the ventilator support time [(27.4±24.3) h vs. (93.4±88.0) h, P=0.018], length of stay in the intensive care unit [(2.8±1.8) d vs. (8.7±6.5) d, P=0.009], and postoperative awakening time [(5.4±2.2) h vs. (8.8±4.8) h, P=0.047] in the experimental group were shorter than those in the control group, with statistically significant differences. ConclusionSingle-branch intraoperative stent combined with modified bilateral cerebral perfusion can effectively shorten ventilator support time, length of stay in the intensive care unit, and postoperative awakening time, and is safe and effective for the treatment of type A aortic dissection, which is worth further promotion.
