Prognostic influence of weight loss on overweight/obese young heart failure patients.

OBJECTIVES: To explore the prognostic influence of weight loss (WL) on young overweight/obesity (OW/OB) individuals with heart failure (HF).

METHODS: Heart failure enrollees (younger than 45 years, body mass index [BMI] of ≥25 kg/m2 ) who received medical treatment at Beijing Chaoyang Hospital, Beijing, China, were classified into 2 groups according to whether they experienced significant WL (≥5% from baseline one year after discharge). One-year occurrence rate of major adverse cardiac events (MACEs) comprising cardiac death and rehospitalization for HF was determined.

RESULTS: Of the 191 individuals recruited for this study, 47 had significant WL. The incidence of ischemic heart disease and obstructive sleep apnea syndrome, as well as BMI and blood pressure, were higher in those with significant WL compared to the control group. Although there was no noteworthy discrepancy in the occurrence of cardiac death between the 2 groups, significant WL correlated independently with a lower incidence of HF re-hospitalization (hazard ratio [HR]=0.32, 95% confidence interval [CI]: [0.11-0.91], p =0.032) and overall MACEs (HR=0.37, 95% CI: [0.14-0.94], p =0.036) in young OW/OB individuals with HF.

CONCLUSION: Significant WL may correlate with favorable prognosis in OW/OB young HF patients.
