Abstract
BACKGROUND
The optimal treatment for heart failure (HF) is a combination of appropriate medications. Controlling the disease using only medical therapy is difficult in patients with HF, severe hypercapnia, and desaturation. These patients should first receive ventilator support followed by pulmonary rehabilitation (PR).
CASE SUMMARY
We report two cases in which arterial blood gas (ABG) improved and PR was possible with appropriate ventilator support. Two patients with extreme obesity complaining of worsening dyspnea–a 47-year-old woman and a 36-year-old man both diagnosed with HF–were hospitalized because of severe hypercapnia and hypoxia. Despite proper medical treatment, hypercapnia and desaturation resolved in neither case, and both patients were transferred to the rehabilitation department for PR. At the time of the first consultation, the patients were bedridden because of dyspnea. Oxygen demand was successfully reduced once noninvasive ventilation was initiated. As the patients’ dyspnea gradually improved to the point where they could be weaned off the ventilator during the daytime, they started engaging in functional training and aerobic exercise. After 4 mo of follow-up, both patients were able to perform activities of daily living and maintain their lower body weight and normalized ABG levels.
CONCLUSION
Symptoms of patients with obesity and HF may improve once ABG levels are normalized through ventilator support and implementation of PR.
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.
