摘  要:目的探讨循环内皮细胞微颗粒(EMP62E、EMP31)和高敏C反应蛋白(hs—CRP)水平变化与慢性左心衰竭严重程度的相关性。方法根据美日纽约心脏病学会(NYHA)心功能分级和左室射血分数(LVEF)将健康对照者和慢性左心衰竭患者分为对照组[LVEF(6.97±4.65)%]、Ⅰ级组[LVEF(42.67±2.06)%]、Ⅱ级组[LVEF(34.26±3.17)%]、Ⅲ级组[LVEF(29.05±1.07)%]和Ⅳ级组[LVEF(25.17±1.42)%]。采用流式细胞仪检测健康对照者和慢性左心衰竭患者EMP62E、EMP31的表达。结果随着NYHA心功能分级的升高和LVEF的下降,EMP62E、EMP31和hsCRP的水平明显上升。Ⅳ级组和Ⅰ级组比较,EMP62E(1092.7±102.8)和(291.0±21.9)个/ul、EMP31(1596.1±46.3)和(477.8±40.3)个μl和hs—CRP(14.7±0.1)和(4.9±0.1)mg/L,差异有统计学意义(均P〈0.01)。结论EMP62E、EMP31和hs-CRP的水平显著升高可能参与了慢性左心衰发生发展的机制。Objective To study the relationship of levels of circulating endothelial mieroparticles (EMP62E, EMP31) and high-sensitivity C reactive protein (hs-CRP) with severity of chronic left heart failure in elderly patients. Methods According to New York Heart Association (NYHA) class and left ventrieular ejection fraction (LVEF), the healthy subjects and the patients were divided into five groups= control group (LVEF: (63.97 ± 4.65)%], class I group (LVEF: (42.67 ± 2.06)%, classl Ⅱgroup 〈LVEF: (34. 26±3.17)%] , class Ⅲ group (I.VEF: (29.05±1.07)%] and class IV group( LVEF: (25. 17±1.42)%]. The levels of circulating EMP62E, EMP31 and hs CRP of the patients and healthy subjects were measured by flow cytometry and nephelometry immunoassay, respectively. Results There were significantly differences in EMPf2E, EMP3] and hs CRP between class Ⅳ group and class I group P〈0.01) EMP62E ((1092.7 ± 102.8) counts/lzl vs. (291.0±21.9) eounts/μl, EMP31 ((1596.1±46.3) counts/L vs. (477.8±40.3) counts/μl) and hs-CRP [(14.74±0.07) mg/L vs. (4.86± 0.09) mg/L. The levels of circulating EMP62E, EMP31 and hs-CRP were gradually elevated significantly along with the increased severity of chronic left heart failure in elderly. Conclusions The upregulation of circulating EMP31, EMPf2E and hs CRP may contribute to the development of chronic heart failure in elderly.
