Predictive value of red cell distribution width on poor myocardial perfusion in patients with acute myo-cardial infarction treated by PCI / 心血管康复医学杂志

ABSTRACT

Objective:To study the predictive value of red cell distribution width (RDW)on poor myocardial perfu- sion in patients with acute myocardial infarction(AMI)treated by percutaneous coronary intervention (PCI).Meth-odsFrom August 2013 to August 2015,a total of 212 ACS patients undergoing PCI in our hospital were selected. According to RDW of blood analyzer,patients were divided into RDW50% were regar- ded as good myocardial perfusion group (n=134).Clinical data were compared between two groups,and single fac- tor and multi-factor analysis were used to analyze influencing factors for myocardial perfusion.Results:Compared with RDW<13.0% group,there were significant rise in age [(62.85±5.23)years vs.(67.33±6.17)years],and significant reductions in left ventricular ejection fraction [LVEF,(52.37±6.14)% vs.(50.55±5.53)%]and STR [(0.73±0.26)vs.(0.57±0.39)]in RDW≥13.0% group,P<0.05 or <0.01. Compared with good myocardial perfusion group,there were significant reductions in percentage of RDW<13% (59.70% vs.44.87%)and LVEF [(52.25±3.81)% vs.(50.29 ± 4.08)%],and significant rise in age [(63.29 ± 1.93)years vs.(66.42 ± 2.15) years]in poor myocardial perfusion group,P<0.05 all.Multi-factor Logistic regression analysis indicated that age, LVEF and RDW were independent predictors for poor myocardial perfusion (r=3.826~6.525,P<0.01 all).Con-clusionRed cell distribution width possesses good predictive value for poor myocardial perfusion in patients with a- cute myocardial infarction undergoing percutaneous coronary intervention,which is worth extending in clinic.
