This study evaluated the effects of up-titration of HF therapies, consisting of beta-blockers, angiotensin-converting-enzyme inhibitors (ACEis)\/angiotensin-receptor blockers (ARBs) and mineralocorticoid receptor antagonists (MRAs), in patients with new-onset HF with and without AF.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Among 607 patients with new-onset HF (&amp;lt;3 months) from a specialized nurse-led HF clinic in the Netherlands, 187 (31%) patients had AF, and 420 (69%) patients were in sinus rhythm at baseline electrocardiogram. After an up-titration period of 9 months, achieved doses and reasons for not reaching target doses were documented.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Patients with AF were older, less likely to have ischaemic heart disease and had higher baseline N-terminal B-type natriuretic peptide levels (all P &amp;lt; 0.05). Left ventricular ejection fraction (LVEF) at baseline was similar between patients with AF and those in sinus rhythm (37% vs. 36%, P = 0.453). Prescription of GDMT was comparable between patients with AF and those in sinus rhythm, except for a lower ACEi\/ARB prescription and higher use of diuretics in patients with AF (79% vs. 86%; P = 0.038; 86% vs. 59%, P &amp;lt; 0.001, respectively, compared with sinus rhythm). Up-titration to guideline-recommended target doses of beta-blocker, ACEi\/ARB and MRA therapy was similar between patients with and without AF (31% vs. 24%, P = 0.096; 32% vs. 40%, P = 0.098; 23.7% vs. 30.5%, P = 0.125, respectively). Reasons for not further up-titrating to recommended target doses were consistent across patients with AF and sinus rhythm. LVEF improvement of \u22655% and \u226510% after up-titration was more common in patients with AF than those in sinus rhythm (67% vs. 53%, P = 0.017; 48% vs. 36%, P = 0.043). Achieving target doses of ACEi\/ARB and MRA therapies was associated with lower mortality and HF rehospitalization rates at 3 years in both patients with AF and those in sinus rhythm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In patients with new-onset HF, up-titration to recommended doses of GDMT was similar in patients with and without AF, but was associated with a greater improvement in LVEF in patients with AF.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ehf2.15188","type":"journal-article","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T07:39:31Z","timestamp":1739950771000},"page":"1703-1713","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Up-Titration of Medication in Patients with New-Onset Heart Failure with and Without Atrial Fibrillation"],"prefix":"10.1093","volume":"12","author":[{"given":"Arietje J.L.","family":"Zandijk","sequence":"first","affiliation":[{"name":"Department of Cardiology, University of Groningen, University Medical Center Groningen , Groningen ,","place":["The Netherlands"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernadet T.","family":"Santema","sequence":"additional","affiliation":[{"name":"Department of Cardiology, University of Groningen, University Medical Center Groningen , Groningen ,","place":["The Netherlands"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Friso D.J.","family":"Inkelaar","sequence":"additional","affiliation":[{"name":"Department of Cardiology, University of Groningen, University Medical Center Groningen , Groningen ,","place":["The Netherlands"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martje H.L.","family":"van der Wal","sequence":"additional","affiliation":[{"name":"Department of Cardiology, University of Groningen, University Medical Center Groningen , Groningen ,","place":["The Netherlands"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janke","family":"Warink-Riemersma","sequence":"additional","affiliation":[{"name":"Department of Cardiology, University of Groningen, University Medical Center Groningen , Groningen ,","place":["The Netherlands"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michiel","family":"Rienstra","sequence":"additional","affiliation":[{"name":"Department of Cardiology, University of Groningen, University Medical Center Groningen , Groningen ,","place":["The Netherlands"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriaan A.","family":"Voors","sequence":"additional","affiliation":[{"name":"Department of Cardiology, University of Groningen, University Medical Center Groningen , Groningen ,","place":["The Netherlands"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,2,19]]},"reference":[{"key":"2026021804264392500_ehf215188-bib-0001","doi-asserted-by":"publisher","first-page":"2","DOI":"10.1016\/s0002-9149(02)03373-8","article-title":"Atrial fibrillation in heart failure: epidemiology, pathophysiology, and rationale for therapy","volume":"91","author":"Maisel","year":"2003","journal-title":"Am J Cardiol"},{"key":"2026021804264392500_ehf215188-bib-0002","doi-asserted-by":"publisher","first-page":"447","DOI":"10.1016\/j.jchf.2019.03.005","article-title":"Heart failure and atrial fibrillation, like fire and fury","volume":"7","author":"Carlisle","year":"2019","journal-title":"JACC Heart Fail"},{"key":"2026021804264392500_ehf215188-bib-0003","doi-asserted-by":"publisher","first-page":"3599","DOI":"10.1093\/eurheartj\/ehab368","article-title":"2021 ESC guidelines for the diagnosis and treatment of acute and chronic heart failure","volume":"42","author":"McDonagh","year":"2021","journal-title":"Eur Heart J"},{"key":"2026021804264392500_ehf215188-bib-0004","doi-asserted-by":"publisher","first-page":"2235","DOI":"10.1016\/S0140-6736(14)61373-8","article-title":"Efficacy of \u03b2 blockers in patients with heart failure plus atrial fibrillation: an individual-patient data meta-analysis","volume":"384","author":"Kotecha","year":"2014","journal-title":"Lancet"},{"key":"2026021804264392500_ehf215188-bib-0005","doi-asserted-by":"publisher","first-page":"21","DOI":"10.1016\/j.jchf.2012.09.002","article-title":"Beta-blockers and outcome in heart failure and atrial fibrillation: a meta-analysis","volume":"1","author":"Rienstra","year":"2013","journal-title":"JACC Heart Fail"},{"key":"2026021804264392500_ehf215188-bib-0006","doi-asserted-by":"publisher","first-page":"891","DOI":"10.1002\/ejhf.592","article-title":"2016 ESC guidelines for the diagnosis and treatment of acute and chronic heart failure: the task force for the diagnosis and treatment of acute and chronic heart failure of the European Society of Cardiology (ESC).
