Examining the Impact of Obesity on Ventilatory Responses During Acute Exercise in Patients with HFpEF

PURPOSE: Heart Failure (HF) is a major cause of morbidity and mortality worldwide. Ventilatory responses to acute exercise have important prognostic value in HF patients. This study examined baseline ventilatory measures to determine if obesity further impacts ventilatory responses in normal subjects and heart failure patients with preserved ejection fraction (HFpEF). METHODS: All participants performed a cardiopulmonary exercise test to maximal...
