Does higher BMI reduce mortality risks in outpatients with established HF?
In outpatients with established heart failure, being overweight or obese is paradoxically associated with a lower risk of death compared to having a healthy weight.
In a cohort of outpatients with established HF, higher BMIs were associated with lower mortality risks; overweight and obese patients had lower risk of death compared with those at a healthy weight. Understanding the mechanisms and impact of the "obesity paradox" in patients with HF is necessary before recommendations are made concerning weight and weight control in this population.
Curtis et al. (Mon,) studied this question.
