Background Obesity is associated with incident heart failure (HF), but is paradoxically associated with better prognosis during chronic HF. Methods We studied 6,142 patients with acute decompensated HF from 12 prospective observational cohorts followed across 4 continents. Primary outcome was all-cause mortality. Cox proportional hazards models and net reclassification index (NRI) described associations of BMI with all-cause mortality. Results “Normal” weight patients (BMI 18.5-25 kg/m2) were older with more advanced HF and lower cardiometabolic risk. Despite worldwide heterogeneity in clinical features across obesity categories, a higher BMI remained associated with decreased 30-day and 1-year mortality (11% decrease at 30 days; 9% decrease at 1 year per 5 kg/m2; P<0.05), after adjustment for clinical risk. BMI obtained at index admission provided effective 1-year risk reclassification beyond current markers of clinical risk (NRI 0.119, P <.001). Notably, the “protective” association of BMI with mortality was confined to those with older age (>75; HR=0.82, P=0.006), decreased cardiac function (ejection fraction < 50%; HR=0.85, P<.001), non-diabetics (HR=0.86, P<.001), and de novo HF (HR=0.89, P=0.004). Conclusions A lower BMI is associated with age, disease severity, and a higher risk of death in ADHF. The “obesity paradox” is confined to older individuals, decreased cardiac function, less cardiometabolic illness, and recent onset HF, suggesting that aging, HF severity/chronicity, and metabolism may explain the obesity paradox.
