Acute cerebrovascular disease (ACVD) is associated with high morbidity and mortality rates, however, molecular markers to aid in its early detection are lacking. In this study, we examined the correlation between serum ischemia-modified albumin (IMA), a marker used to identify ischemic events in the heart, and blood lipids in patients with ACVD. Serum IMA levels were determined by enzyme-linked immuno-sorbent assay, and total cholesterol (TC), low-density lipoprotein (LDL), high‑density lipoprotein cholesterol (HDL) and triglyceride (TG) levels were determined biochemically in 62 patients with cerebral infarction (CI), 40 patients with intracerebral hemorrhage (ICH), 18 patients with subarachnoid hemorrhage (SAH) and 100 healthy individuals (controls). Serum IMA levels were significantly higher in each of the ACVD groups compared to the control group (CI, 80.81±11.97 U/ml; ICH, 80.25±10.91 U/ml; SAH, 74.43±11.39 U/ml and control, 41.08±5.10 U/ml; P<0.05). Additionally, serum TC, LDL and TG levels significantly increased, while serum HDL significantly decreased in the ACVD groups compared to the control group (P<0.05). A positive correlation was found between serum IMA levels and serum TC, LDL and TG levels in the ACVD patients, while serum IMA levels were negatively correlated with serum HDL levels (P<0.05). Thus, serum IMA increased following an ACVD event and was closely correlated with changes in the blood lipid levels. These factors, when combined, may allow the development of molecular markers for an earlier diagnosis of ACVD.
急性脑血管病(ACVD)与高发病率和死亡率相关,但缺乏用于早期检测的分子标志物。在这项研究中,我们研究了血清缺血修饰白蛋白(IMA)与 ACVD 患者血脂之间的相关性,IMA 是一种用于识别心脏缺血事件的标志物。通过酶联免疫吸附试验测定血清 IMA 水平,通过生化方法测定 62 例脑梗死(CI)患者、40 例脑出血(ICH)患者、18 例蛛网膜下腔出血(SAH)患者和 100 例健康个体(对照组)的总胆固醇(TC)、低密度脂蛋白(LDL)、高密度脂蛋白胆固醇(HDL)和甘油三酯(TG)水平。与对照组相比,ACVD 各组的血清 IMA 水平均显著升高(CI:80.81±11.97 U/ml;ICH:80.25±10.91 U/ml;SAH:74.43±11.39 U/ml;对照组:41.08±5.10 U/ml;P<0.05)。此外,与对照组相比,ACVD 各组的血清 TC、LDL 和 TG 水平显著升高,而血清 HDL 水平显著降低(P<0.05)。ACVD 患者的血清 IMA 水平与血清 TC、LDL 和 TG 水平呈正相关,而与血清 HDL 水平呈负相关(P<0.05)。因此,ACVD 事件后血清 IMA 增加,与血脂水平变化密切相关。这些因素结合起来,可能为 ACVD 的早期诊断开发分子标志物。
