Heart failure & cardiomyopathies
Epidemiology and Treatment of Heart Failure with Chronic Obstructive Pulmonary Disease in Canadian Primary Care
Authors' conclusion
The prevalence of HF and COPD continues to rise. Although patients with either or both conditions are high utilizers of primary care, the majority of visits relate to non-cardiorespiratory comorbidities. Medical therapy for HF was similar and the initially lower beta-blocker utilization disappeared over time.
Study context
- Population
- All patients with Heart Failure (HF) or Chronic Obstructive Pulmonary Disease (COPD) in the Canadian Primary Care Sentinel Surveillance Network, 2010–2018population size in 2018
- Participants
- 15,778 / 27,927 / 4,768
- Exposure
- HF alone vs COPD alone vs HF with COPD
- HFn = 15,778
- COPDn = 27,927
- HF with COPDn = 4,768
- Outcome
- Age-sex-standardized prevalence per 100 population
- Follow-up
- 2010 to 2018
Main finding
As reported in the abstract
HF alone prevalence increased
2.33 to 3.63
COPD alone prevalence increased
3.44 to 5.96
COPD with HF prevalence increased
12.70 to 15.67
Observational data: associations, not effects.
Further findings
Annual visit rates
- COPD alone: high and stable
- around 8
- HF alone: declined
- 9.3-8.1, P = 0.04
- Both conditions: declined
- 14.3-11.9, P = 0.006
Visit reasons
- HF alone: CV visits
- 29.4%
- HF alone: respiratory visits
- 3.5%
- COPD alone: respiratory visits
- 16.4%
- COPD alone: CV visits
- 11.3%
- Concurrent disease: cardiorespiratory visits
- 39.0%
- Majority of visits non-cardiorespiratory in HF alone and COPD alone
HF medical therapy, HF with vs without COPD
- Beta-blocker use initially, COPD with HF vs HF alone
- 69.3% vs. 74.0%
- Beta-blocker use by 2018, COPD with HF vs HF alone
- 74.5% vs. 73.5%
- ACEi/ARB/ARNI use similar
- MRA use marginally higher with concurrent COPD
