Despite this, CRT implantation during HFH is common. This study aimed to compare the clinical profiles and post\u2010implantation outcomes of patients undergoing inpatient CRT during HFH with those receiving deferred outpatient CRT after HFH.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Institutional CRT data were linked with the National Heart Failure Audit from January 2014 to December 2024. Patients were stratified by inpatient or outpatient CRT implantation setting. Baseline characteristics, HFH within one year of CRT and long\u2010term survival were compared. Multivariable Cox proportional hazards modelling assessed the association between implantation setting and mortality.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n 130 patients underwent inpatient CRT during HFH and 90 received deferred outpatient CRT. Inpatients had lower estimated glomerular filtration rates (46.26\u00b119.0 vs. 55.19\u00b118.4\u00a0mL\/min\/1.73m\n 2<\/jats:sup>\n ,\n p<\/jats:italic>\n = 0.01), more ischemic cardiomyopathy (40.8% vs. 18.9%,\n p<\/jats:italic>\n = 0.01), less left bundle branch block (36.9% vs. 51.1%,\n p<\/jats:italic>\n = 0.04), and more HF hospitalizations in the year before CRT (1.12\u00b10.87 vs. 0.84\u00b10.86,\n p<\/jats:italic>\n = 0.01). The risk of \u22651 HF re\u2010hospitalization within one year of CRT was higher (23.1% vs. 7.8%;\n p<\/jats:italic>\n = 0.004) in the inpatient group. Median survival after CRT was 2.9 years shorter for the inpatient group (1192 vs. 2262 days,\n p<\/jats:italic>\n = 0.003). After adjustment, deferred outpatient CRT remained associated with lower all\u2010cause mortality (HR 0.56, 95% CI 0.35\u20130.88,\n p<\/jats:italic>\n = 0.01).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Patients selected for inpatient CRT during HFH represent a clinically distinct, higher\u2010risk subgroup with worse post\u2010implant outcomes. Prospective studies are needed to optimize patient selection for inpatient CRT.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/pace.70366","type":"journal-article","created":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T08:56:06Z","timestamp":1784537766000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Inpatient Cardiac Resynchronization Therapy During Heart Failure Hospitalization: A Distinct High\u2010Risk Phenotype"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-7261-8840","authenticated-orcid":false,"given":"Oliver","family":"Rees","sequence":"first","affiliation":[{"name":"St George's University Hospitals NHS Foundation Trust London UK"},{"name":"Cardiovascular Clinical Academic Group City St George's, University of London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Dargan","sequence":"additional","affiliation":[{"name":"St George's University Hospitals NHS Foundation Trust London UK"},{"name":"Cardiovascular Clinical Academic Group City St George's, University of London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jemima","family":"Weir","sequence":"additional","affiliation":[{"name":"St George's University Hospitals NHS Foundation Trust London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"Ray","sequence":"additional","affiliation":[{"name":"St George's University Hospitals NHS Foundation Trust London UK"},{"name":"Cardiovascular Clinical Academic Group City St George's, University of London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Rosano","sequence":"additional","affiliation":[{"name":"St George's University Hospitals NHS Foundation Trust London UK"},{"name":"Cardiovascular Clinical Academic Group City St George's, University of London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fadi","family":"Johura","sequence":"additional","affiliation":[{"name":"St George's University Hospitals NHS Foundation Trust London UK"},{"name":"Cardiovascular Clinical Academic Group City St George's, University of London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,20]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehab364"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehab368"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ejhf.1192"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ejhf.781"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/euq319"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/clc.23135"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/euad059"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.7861\/clinmed.2023\u20102023\u201023.5.Cardio1"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/pace.12883"},{"key":"e_1_2_13_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2007.02.037"}],"container-title":["Pacing and Clinical Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.70366","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/pace.70366","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.70366","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T08:56:07Z","timestamp":1784537767000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pace.70366"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,20]]},"references-count":10,"alternative-id":["10.1111\/pace.70366"],"URL":"https:\/\/doi.org\/10.1111\/pace.70366","archive":["Portico"],"relation":{},"ISSN":["0147-8389","1540-8159"],"issn-type":[{"value":"0147-8389","type":"print"},{"value":"1540-8159","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,20]]},"assertion":[{"value":"2026-06-12","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-06","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-20","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"pace.70366"}}
