Abstract:
Objective To investigate the correlations of body mass index (BMI) with plasma apelin, waist-hip ratio (WHR), fasting plasma glucose (FPG), glycosylated hemoglobin (HbAlc), biochemical indicator, blood fat and ultrasonic cardiogram (UCG) figures in patients with congestive heart failure (CHF).Methods A total of 41 elderly CHF patients (20 males and 21 females, aged 66.0±12.3 years) were divided into 3 groups according to BMI: normal group (n= 16), overweight group (n=13) and obese group (n= 12).And they were also divided into 2 subgroups: grade Ⅲ heart function group (n=22) and grade Ⅳ heart function group (n= 19).Enzyme linked immunosorbent assay was used to detect the levels of plasma apelin, and BMI, WHR, C-reactive protein (CRP), FPG, creatine kinase (CK), CK-MB, blood fat, electrolyte and UCG of all patients were detected .Results There were significant differences in waist circumference, hip circumference and WHR among the 3 groups (P<0.05 or P<0.01).But there were no significant differences in high density lipoprotein (HDL), low density lipoprotein (LDL), total cholesterol (TC), triglyceride (TG), FPG, HbAlc, CK, CK-MB, potassium, sodium, CRP, left ventricular internal diameter at end-diastole (LVIDd), left ventricular internal diameter at end-diastole (LVIDs), interventricular septal thickness at end diastole (IVSd) and left ventrieular ejection fraction (LVEF) among the 3 groups (all P> 0.05).The apelin level was higher in obese group than in normal group and in overweight group ((0.48±0.15) mg/L vs.(0.18±0.15) mg/L and (0.27±0.06) mg/L, both P<0.01].And the plasma apelin level was higher in grade Ⅳ heart function group than in grade Ⅲ heart function group [(0.35±0.16) mg/L vs.(0.26±0.13)mg/L, P<0.05].The level of plasma apelin was positively correlated with BMI, white blood cell, CK, hemoglobin and TG, and was negatively correlated with cardiac function and LVEF.The influencing factors for the plasma apelin were BMI (β=0.672, P<0.01), age (β=0.244, P<0.05) and HDL (β=-1.000, P<0.01).Conclusions The plasma apelin level is closely correlated with the development of heart failure.Cardiac dysfunction is more severer when the level of plasma apelin is higher.The high level of plasma apelin may be one of factors for the higher survival rate of the obese CHF patients.Plasma apelin level may be used as an indicator of state of illness.
