The Impact of Body Mass Index on Survival and Clinical Outcomes in Pulmonary Arterial Hypertension: Revisiting the Obesity Paradox

Our findings contribute to the understanding of the obesity paradox in PAH, revealing a potential trend toward improved survival in obese PAH patients despite more adverse hemodynamic profiles. These results underscore the need for further research to elucidate the mechanisms underlying the obesity paradox in PAH and to determine if BMI-targeted management strategies may benefit this population.
