In patients with heart failure (HF), increasing chronic obstructive pulmonary disease (COPD) severity is associated with increasing risk of mortality and hospitalization, a recent study found. In this population-based study, researchers sought to determine the associations between COPD medication intensity or state of airflow limitation and the risk of hospitalization or death in patients with HF. Participants were aged ≥40 years with a new diagnosis of HF in their family practice clinical record. In patients with HF, those with COPD were compared to those without it. The primary outcome was first all-cause admission or all-cause death. Among the findings:
- There were 50,114 patients with new HF (median age 79 years) during the study period.
- COPD increased the risk of hospital admission and death by > one-third, but increased risk was specific to patients receiving the most intense COPD medication regimens.
- Availability of spirometry data was limited but showed the increasing airflow limitation was associated with increased risk of mortality.
