急性心衰患者红细胞分布宽度与超声心动图参数的相关性分析

目的探讨急性心衰患者红细胞分布宽度(RDW)与超声心动图参数之间的相关性。方法将89例急性心衰患者按RDW值等分为A、B、C三组,对其化验结果和超声心动图参数进行对比分析。结果 C组(>14.5%)的E/E’明显高于A组(<12.5%)(P<0.001)。对RDW的单因素分析和E/E’的多元线性回归分析表明RDW与E/E’之间存在显著的相关性。结论急性心衰患者较高水平的RDW与升高的E/E’之间存在相关,推测RDW与升高的LVFP也相关。

Correlation analysis between red cell distribution width and echocardiographic parameters in patients with acute heart failure

Objective To explore the correlation between red cell distribution width(RDW)and echocardiographic parameters in patients with acute heart failure(AHF).Methods A total of 89 patients with AHF involved in the study were equally divided into three groups(A,B,C)according to RDW.The laboratory testing results and echocardiographic parameters of the patients were statistically analyzed.Results The E/E' of Group C(>14.5%)was significantly higher than that of Group A(<12.5%)(P<0.001).A significant correlation between RDW and E/E' was indicated by single factor correlation analysis and multiple linear regression analysis.Conclusion There exists a correlation between higher levels of RDW and elevated E/E',and it is presumed that RDW may be associated with elevated LVFP in patients with AHF.
