摘 要:目的分析陈旧性心肌梗死老年患者外周血Toll样受体2(TLR2)、TLR4、超敏C-反应蛋白(hs—CRP)和可溶性ST2蛋白(sST2)的表达和临床意义。方法选择2010年1月至2014年3月老年陈旧性心肌梗死合并慢性左心衰竭患者140例,对照组50例。采用流式细胞术检测血清TLR2和TLR4水平的变化,并与hs—CRP进行对照分析。应用免疫散射比浊法测定hs—CRP的水平。采用双夹心抗体酶联免疫吸附法定量检测sST2。结果老年陈旧性心肌梗死患者,随着心肌梗死程度的加重,hs—CRP、TLR2、TLR4和sST2水平升高。冠状动脉单支与4支病变患者hs—CRP(1.9±0.9)mg/L比(14.9±1.9)mg/L、TLR2:(7.5±0.9)MFI比(15.1±1.8)MFI、TLR4:(5.5±0.8)MFI比(11.8±7.1)MFI、sST2:(22.6±0.4)ng/ml比(28.7±0.9)ng/ml(均P〈0.01);NYHAI级组与NYHAⅣ级组hs—CRP(1.9±0.2)mg/L比(15.0±1.9)mg/L、TLR2:(7.3±0.2)MFI比(16.7±2.9)MFI、TLR4:(5.8±0.9)MFI比(17.9±6.9)MFI、sST2:(22.4±0.6)μg/L比(30.3±1.0)μg/L(均P〈0.01);随加拿大心血管病学会(CCS)心绞痛分级升高,hs—CRP、TLR2、TLR4和sST2水平增高;随着美国心脏病学会心功能分级增高,hs—CRP、TLR2、TLR4和sST2水平上升,各NYHA级别组间比较,差异有统计学意义(均P〈0.01)。结论hs—CRP、TLR2、TLR4和sST2水平的变化可能影响老年人陈旧性心肌梗死的严重程度。Objective To study the serum level changes in Toll-like receptor 2, 4 and soluble ST2 in the circulation in elderly patients with old myocardial infarction and the clinical significance. Methods A total of 140 patients with old myocardial infarction combined with chronic left-sided heart failure from Jan. 2010 to Mar. 2014, and 50 controls were selected. Serum level changes in TLR2 and TLR4 were detected by flow cytometry and compared with hs-CRP. The levels of hs-CRP and sST2 were tested by nephelometry immunoassay and enzyme-linked immunosorbent assay (ELISA) respectively. Results The levels of hs-CRP, TLR2, TLR4 and sST2 were elevated along with the severity of old myocardial infarction in elderly patients. The levels of hs-CRP, TLR2, TLR4 and sST2 were lower in patients with single vessel disease than in patients with four-vessel disease [ hs-CRP: (1.9±0.9) mg/L vs. (14.9±1.9) mg/L, TLR2:(7.5±0.9) MFI vs. (15.1±1.8) MFI, TLR4L(5.5±0.8) MFI vs. (11.8±7.1) MFI, sST2.. (22.6±0.4)μg/L vs. (28.7±0.9)μg/L, all P〈 0. 013. Levels of hs-CRP, TLR2, TLR4 and sST2 were lower in patients with NYHA I than in patients with NYHA Ⅳ[hs-CRP: (1.9±0.2) mg/L vs. (15.0±1.9) rag/L, TLR2: (7.3±0.2) MFI vs. (16.7±2.9)MFI, TLR4: (5.8±0.9) MFI vs. (17.9±6.9) MFI, sST2: (22.4±0.6)μg/ L vs. (30.3±1.0) μg/L, all P〈0.013. The levels of hs-CRP, TLR2, TLR4 and sST2 were gradually increased along with the increases of Canadian Cardiovascular Society Angina Pectoris Grade and cardiac function classification of the American College of Cardiology (all P〈0.01). Conclusions Serum level changes in hs-CRP, TLR2, TLR4 and sST2 in elderly patients with old myocardial infarction may become the new indicators to forecast the degree of old myocardial infarction.
