Core Tip

Core Tip: We describe two patients with heart failure (HF) and obesity who experienced respiratory failure, including hypercapnia and hypoxia. Neither patient demonstrated a significant response to pharmacological management; however, in both cases, symptoms improved with noninvasive ventilation, and they were able to return to their daily life. These findings suggest that in patients with obesity and HF who developed pulmonary hypertension and cor pulmonale may need to be treated for obesity hypoventilation and sleep apnea. The symptoms of these comorbidities may improve when arterial blood gas levels are normalized with appropriate ventilator support and pulmonary rehabilitation.
