Heart failure & cardiomyopathies
The intersection of obesity and acute heart failure: cardiac structure and function and congestion across body mass index (BMI) categories
Authors' conclusion
Among patients with AHF, those with overweight/obesity had greater biventricular volumes/area and LV mass, similar sonographic evidence of haemodynamic congestion and less pulmonary congestion than those with normal weight. The risk of 6-month HF hospitalization or death was similar across BMI groups.
Study context
- Population
- Adults hospitalised for acute heart failure (HF), by BMI and left ventricular ejection fraction (LVEF) (>40% HFmrEF/HFpEF vs ≤40% HF with reduced EF (HFrEF))
- Participants
- 354 adults
- Exposure
- Overweight and obese vs normal weight
- Outcome
- Cardiac structure and function and congestion across BMI groups
- Follow-up
- Baseline
Main finding
As reported in the abstract
Observational data: associations, not effects.
Further findings
HF hospitalisation or all-cause death · 6 months
- Risk similar across BMI groups, overall and stratified by LVEF
Patient characteristics by BMI
- Higher BMI: younger age, more comorbidities, more prior HF, worse patient-reported symptoms
