Higher BMI is associated with lower mortality risk in patients with severe PH

A study of over 1,100 patients with severe PH found that higher BMI was associated with lower one-year mortality rates, even after adjusting for other factors. The researchers suggest that increased levels of serum lipoproteins in obese individuals may play a role in neutralizing circulating toxins and inflammatory proteins.
