Methods: Consecutive HFpEF patients were enrolled and indexed RA volumes and emptying fractions (RA-EF) were assessed by cardiac magnetic resonance imaging (CMR). For patients in SR, feature tracking of the RA wall was performed during CMR. In addition, all patients underwent right and left heart catheterization and 6 min walk distance (6MWD) and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) evaluations. We prospectively followed patients and used Cox regression models to determine the association of RA size and function with a composite endpoint of heart failure hospitalization and cardiovascular death. Results: A total of 188 patients (71% female patients, 70 \u00b1 8 years old) were included. Ninety-two patients (49%) were in persistent AF. Eighty-five patients reached the combined endpoint during a follow-up of 69 (42\u201397) months. After a multivariate cox regression analysis, the impaired RA reservoir strain (HR 0.949; 95% CI [0.909\u20130.990], p = 0.016), the RA reservoir strain rate (HR 0.991; 95% CI [0.983\u20130.999], p = 0.028), the RA conduit strain (HR 0.932; 95% CI [0.879\u20130.988], p = 0.019), and the RA conduit strain rate (HR 0.989; 95% CI [0.881\u20130.997], p = 0.011) were significantly associated with a worse outcome for patients in SR. In persistent AF, no RA imaging parameter was related to outcome after a multivariate regression analysis. Conclusions: In HFpEF patients in SR, CMR parameters of impaired RA conduit and reservoir function are associated with dismal cardiovascular outcomes. In persistent AF, RA parameters lose their prognostic ability.<\/jats:p>","DOI":"10.3390\/jcm12165179","type":"journal-article","created":{"date-parts":[[2023,8,9]],"date-time":"2023-08-09T10:21:50Z","timestamp":1691576510000},"page":"5179","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Right Atrial Phasic Function in Heart Failure with Preserved Ejection Fraction: Cardiac Magnetic Resonance Feature Tracking and Outcomes"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8411-9716","authenticated-orcid":false,"given":"Robert","family":"Sch\u00f6nbauer","sequence":"first","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fiona","family":"Hana","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7519-5274","authenticated-orcid":false,"given":"Franz","family":"Duca","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6164-8773","authenticated-orcid":false,"given":"Matthias","family":"Koschutnik","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Don\u00e0","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Nitsche","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9016-2975","authenticated-orcid":false,"given":"Michael","family":"Sponder","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3539-994X","authenticated-orcid":false,"given":"Max","family":"Lenz","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonghui","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Loewe","sequence":"additional","affiliation":[{"name":"Department of Bioimiging and Image-Guided Therapy, Division of Cardiovascular and Interventional Radiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8284-2994","authenticated-orcid":false,"given":"Christian","family":"Hengstenberg","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Mascherbauer","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7632-9879","authenticated-orcid":false,"given":"Andreas","family":"Kammerlander","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine II, Division of Cardiology, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","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.
