Authors' conclusion

These data from 5 large-scale HFmrEF/HFpEF clinical trials further question the utility of BMI as the sole measure to define obesity. WC or WHtR assessment identifies a substantial number of individuals with abdominal obesity despite BMI <30 kg/m2, and may enhance risk stratification beyond BMI alone in HFmrEF/HFpEF.

Study context

Population
Adults with heart failure with mildly reduced ejection fraction (HFmrEF)/heart failure with preserved ejection fraction (HFpEF)WC and WHtR in 7,827
Participants
21,479 adults
Comparison
Adiposity-related anthropometrics and heart failure (HF) and mortality outcomes

Pooled result

As reported in the abstract

Association of adiposity-related anthropometrics (BMI, WHtR) with HF and mortality outcomes
  • BMI showed complex J- and U-shaped associations with clinical outcomes
  • Higher WHtR linearly associated with increased risk of HF and mortality events
  • Independent of BMI, higher WHtR associated with adverse outcomes
  • Independent of WHtR, higher BMI associated with HF hospitalization
  • Elevated BMI and WHtR: higher rates of CV death or HF hospitalization vs elevated BMI or WHtR alone

Further pooled results

Adiposity prevalence at baseline

BMI ≥30 kg/m²
46%
Elevated WC or WHtR
95%
Excess abdominal adiposity among BMI <30 kg/m² (especially older and female)
89%

Modifiers of the BMI–WHtR association

Sex: women vs men had higher WHtR at higher BMI
P for interaction = 0.003
Race: Asian and Black participants had higher WHtR at lower BMI
P for interaction = 0.046

CV death or HF hospitalization, by age

Younger participants had steepest associations of BMI or WHtR with outcome
P for interaction < 0.001
  • interaction P <0.001 for both
