How are patients with heart failure treated in primary care?
.

OBJECTIVE: The aim of this study was to assess the adherence of general practitioners (GPs) to guidelines in patients with heart failure with reduced ejection fraction (HFrEF) and to describe GPs' prescribing behavior regarding patients with heart failure with preserved ejection fraction (HFpEF). MATERIALS AND METHODS: Cross-sectional study as part of the ETIC trial. Five classes of drugs were described: angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs); ß-blockers (BBs); mineralocorticoid receptor antagonists (MRAs); diuretics (thiazide or loop diuretics); and digoxin. RESULTS: 178 patients were studied: their mean age was 73.5 years (± 10.6). Of the 128 patients with HFpEF, 81.3% received ACEIs or ARBs, 63.3% received BBs, 13.3% received MRAs, 75.8% received diuretics, and 12.5% received digoxin. Of the 50 patients with HFrEF, 84% received ACEIs or ARBs, 74% received BBs, 20% received MRAs, 76% received diuretics, and 2% received digoxin. 25% of the patients were given a drug in accordance with the recommendations for drug class but not a drug authorized for the HFrEF indication. Among the patients with HFrEF who were treated in accordance with the recommendations, target doses were achieved in 1/3 given ACEIs/ARBs, 1/4 given BBs, and 1/2 given MRAs. Only 6% of the patients had a perfect Global Adherence Indicator-3 (GAI-3) with all target doses achieved. CONCLUSION: Several drugs were prescribed even though they were not recommended, and few patients were treated optimally. It seems to be necessary to develop a pragmatic tool to help GPs and cardiologists in optimizing treatment.
