【摘要】:目的观察慢性心力衰竭(Chronic heart failure CHF)患者血浆中可溶性ST2(s ST2)的水平变化,并探讨其临床意义。方法收集宁夏医科大学心血管病医院心血管内科2014年10月至2015年10月收住的慢性心力衰竭患者100例(心衰组)和同期无器质性疾病体检者30例(对照组);所有心力衰竭患者均符合我国最新版心力衰竭诊疗指南规定的诊断标准;心衰组按纽约心脏病协会(NYHA)心功能分级分为心功能Ⅱ级组、Ⅲ级组和Ⅳ级组,分别为35例、32例及33例,按左室射血分数(LVEF)水平分为射血分数降低(HFrEF)组52例和射血分数保留(HFpEF)组48例。采用酶联免疫吸附测定(ELISA)法检测血浆sST2、脑利钠肽(BNP)水平,常规超声心动图测定左室射血分数(LVEF)、左室舒张末期内径(LVDd)、收缩末期内径(LVDs)及左室短轴缩短率(LVFS),比较不同分组患者血浆sST2水平的变化,并分析其与脑钠尿肽、NYHA分级及心脏超声各个指标的相关性。结果1、血浆sST2水平经对数转换后在NYHAⅡ~Ⅳ级组明显高于对照组(3.00±0.08;3.06±0.12;3.08±0.10 VS 2.91±0.13),各组间多重比较差异均有统计学意义(P0.05);2、Log sST2在HFpEF组、HFrEF组均高于对照组(3.02±0.09;3.07±0.12 VS 2.91±0.13)(P0.05),各组间多重比较差异均有统计学意义(P0.05);3、Pearson相关性分析显示,经对数转换后的血浆sST2(Log sST2)与经对数转换后的血浆BNP(Log BNP)、NYHA分级、LVDd、LVDs呈正相关(r=0.454、0.480、0.462、0.454,P均0.01),与LVEF、LVFS呈负相关(r=-0.409、-0.396,P均0.01)。结论(1)慢性心衰患者血浆sST2水平均明显升高,且随着心衰严重程度的增加而逐渐升高,与NYHA分级呈正相关。(2)血浆sST2水平与BNP、左室舒张末期内径、左室收缩末期内径呈正相关,与左室射血分数、左室短轴缩短率呈负相关。(3)血浆sST2可以作为心脏彩超及BNP的有效补充,具有潜在的临床应用价值。
[Abstract]:Objective to observe the changes of plasma soluble ST2 (s ST2) levels in patients with chronic heart failure (Chronic heart failure CHF) and to explore its clinical significance. Methods from October 2014 to October 2015, 100 patients with chronic heart failure (CHF group) and 30 patients without organic diseases (control group) were collected from Cardiovascular Department, Ningxia Medical University. All patients with power failure met the diagnostic criteria stipulated in the latest edition of the guidelines for the diagnosis and treatment of heart failure in China. The heart failure group was divided into three groups according to the (NYHA) cardiac function classification of the New York Heart Association: class 鈪,
