Aims: Implementation of guideline-recommended pharmacological treatment in heart failure (HF) patients remains challenging. In 2021, the European Heart Failure Association (HFA) published a consensus document in which patient profiles were created based on readily available patient characteristics and suggested that treatment adjusted to patient profile may result in better individualized treatment and improved guideline adherence. This study aimed to assess the distribution of these patient profiles and their treatment in a large real-world chronic HF cohort. Methods and results: The HFA combined categories of heart rate, blood pressure, presence of atrial fibrillation, chronic kidney disease, and hyperkalemia into eleven phenotypic patient profiles. A total of 4,455 patients with chronic HF and a left ventricular ejection fraction ≤40% with complete information on all characteristics were distributed over these profiles. In total, 1,640 patients (36.8%) could be classified into one of the HFA profiles. Three of these each comprised >5% of the population and consisted of patients with a heart rate >60 beats per minute with normal blood pressure (>90/60 mmHg) and no hyperkalemia. Conclusion: Nearly forty percent of a real-world chronic HF population could be distributed over the eleven patient profiles as suggested by the HFA. Phenotype-specific treatment recommendations are clinically relevant and important to further improve guideline implementation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Radhoe, Clephas, Linssen, Oortman, Smeele, Van Drimmelen, Schaafsma, Westendorp, Brunner-La Rocca and Brugts.)

Background: Atrial fibrillation (AF) is common in chronic heart failure (HF) patients and influences the choice and effects of drug and device therapy. In this large real-world HF registry, we studied whether the presence of AF affects the prescription of guideline-recommended HF therapy., Methods: We analyzed 8253 patients with chronic HF with reduced ejection fraction (HFrEF) from 34 Dutch outpatient clinics included in the period between 2013 and 2016 treated according to the 2012 ESC guidelines., Results: 2109 (25.6%) of these patients were in AF (mean age 76.8 ± 9.2 years, 65.0% were men) and 6.144 (74.4%) had no AF (mean age 70.7 ± 12.2 years, 63.6% were men). Patients with AF more often received beta-blockers (81.7% vs. 79.7%, p = 0.04), MRAs (57.1% vs. 51.7%, p < 0.01), diuretics (89.7% vs. 80.6%, p < 0.01) and digoxin (40.1% vs. 9.3%, p < 0.01) compared to patients without AF, whereas they less often receive renin-angiotensin-system (RAS)-inhibitors (76.1% vs. 83.1%, p < 0.01). The number of patients who received beta-blockers, RAS-inhibitor and MRA at ≥50% of the recommended target dose was comparable between those with and without AF (16.6% vs. 15.2%, p = 0.07)., Conclusion: In this large cohort of chronic HFrEF patients, the prevalence of AF was high and we observed significant differences in prescription of both guideline-recommended HF between patients with and without AF., Competing Interests: Declaration of competing interest All authors report no conflict of interest., (Copyright © 2020 Elsevier B.V.

Objectives: This study investigated adherence to drug therapy guidelines in heart failure (HF) with reduced left-ventricular ejection fraction (LVEF) of <40% (heart failure with reduced ejection fraction [HFrEF]), in which evidence-based treatment has been established., Background: Despite previous surveys of HF, important uncertainties remain regarding guideline adherence in a representative real-world population., Methods: A cross-sectional registry in 34 Dutch HF outpatient clinics that included 10,910 patients with the diagnosis of HF was examined. Of that number, 8,360 patients had LVEF <50% (72 ± 12 years of age; 64% male) and were divided into HFrEF (n = 5,701), HF with mid-range LVEF (HFmrEF) with LVEF 40% to 49% (n = 1,574), and those with semiquantitatively measured LVEF but <50% (n = 1,085)., Results: In the HFrEF group, 81% of the patients were treated with loop diuretics, 84% with renin-angiotensin-system (RAS) inhibitors, 86% with β-blockers, 56% with mineralocorticoid-receptor antagonists (MRA), and 5% with I f -channel inhibition. Differences in medication use were minor among the 3 groups but were significant among centers. Inability to tolerate the medications was recorded in 9.4% patients taking RAS inhibitors, 3.3% taking β-blockers, and 5.4% taking MRAs. Median loop diuretic dose was 40 mg of furosemide equivalent, RAS inhibitor dose 50% of target, β-blocker dose 25% of target, and MRA dose 12.5 mg of spironolactone equivalent. Elderly patients were treated predominantly with diuretics and less often with RAS inhibitors, β-blockers, and MRAs., Conclusions: This large contemporary HF registry showed a relatively high use of evidence-based treatment, particularly in younger patients. However, the average dose of evidence-based medication was still lower than recommended by guidelines. Furthermore, the more recently introduced I f -channel inhibition has hardly been adopted. There is ample room for improvement of HFrEF therapy, even more than 25 years after convincing evidence that HFrEF treatment leads to better outcome., (Copyright © 2019 American College of Cardiology Foundation.
