Pulmonary function predicts mortality and hospitalizations in outpatients with heart failure and preserved ejection fraction

The presence of airflow limitation or arterial hypoxemia identify a group of patients with HFPEF at higher risk of death or cardiovascular hospitalizations, respectively. Given that both airflow limitation and arterial hypoxemia are treatable, we propose that lung function should be routinely evaluated in the outpatient management of HFPEF patients.
