Abstract:
Objective To investigate the prevalence and prognostic value of anemia in male and female patients with chronic systolic heart failure (CSHF).Methods Data of in-hospital patients with CSHF were investigated between 2000 and 2010 from 12 hospitals in Hubei Province.Patients were divided into normal hemoglobin (Hb) group,mild anemia group,moderate anemia group,severe and extreme anemia group.According to age,body mass index (BMI) and correction of glomerular filtration rate (GFRc),patients were divided into several subgroups,respectively.Multivariate logistic regression was performed to determinate the associated factors with anemia.Kaplan-Meier curve was performed to evaluate the difference in all-cause mortality in male and female patients with anemia.Univariate and multivariate Cox proportion hazard analysis was performed to determinate the risk of all-cause mortality among different anemia group in male and female patients.Results A total of 16681 patients were enrolled.Anemia accounted for 23.79％ and 27.29％,separately,in male and female patients with CSHF.BMI and GFRc were related to anemia in both male and female patients with CSHF,while only age was related to anemia for female patients with CSHF.The hazard ratio of all-cause mortality was 1.08 (P ＜ 0.01),1.13 (P ＜ 0.O1) and 1.02 (P =0.74),respectively,for all,male and female anemia patients with CSHF,compared to normal Hb group.Compared to normal Hb group,the hazard ratio of mild anemia group,moderate anemia group,severe and extreme anemia group was 1.05 (P =0.14),1.20 (P ＜0.01) and 1.36 (P ＜0.01),respectively,for all CSHF patients;1.11 (P ＜ 0.01),1.35 (P ＜ 0.01) and 1.37 (P ＜ 0.01),respectively,for male;0.96 (P=0.48),1.08 (P=0.40) and3.47 (P＜0.01),respectively,for female.Conclusions Compared to male,female patients suffer higher prevalence of anemia in patients with CSHF.There is a significant difference in risk factors and prognosis of anemia between male and female patients with CSHF.
