Objective: To compare the clinical presentation, comorbidities, and long-term outcomes of TICMP patients with IDCM patients. Methods: a retrospective cohort study of patients hospitalized with new-onset TICMP or IDCM. The primary endpoint was a composite of death, myocardial infarction, thromboembolic events, assist device, heart transplantation, and ventricular tachycardia or fibrillation (VT\/VF). The secondary endpoint was recurrent hospitalization due to heart failure (HF) exacerbation. Results: the cohort was comprised of 64 TICMP and 66 IDCM patients. The primary composite endpoint and all-cause mortality were similar between the groups during a median follow-up of ~6 years (36% versus 29%, p = 0.33 and 22% versus 15%, p = 0.15, respectively). Survival analysis showed no significant difference between TICMP and IDCM groups for the composite endpoint (p = 0.75), all-cause mortality (p = 0.65), and hospitalizations due to heart failure exacerbation. Nonetheless, the incidence of recurrent hospitalization was significantly higher in TICMP patients (incidence rate ratio 1.59; p = 0.009). Conclusions: patients with TICMP have similar long-term outcomes as those with IDCM. However, it portends a higher rate of HF readmissions, mostly due to arrhythmia recurrences.<\/jats:p>","DOI":"10.3390\/jcm12041412","type":"journal-article","created":{"date-parts":[[2023,2,10]],"date-time":"2023-02-10T02:56:13Z","timestamp":1675997773000},"page":"1412","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Long-Term Outcomes of Tachycardia-Induced Cardiomyopathy Compared with Idiopathic Dilated Cardiomyopathy"],"prefix":"10.3390","volume":"12","author":[{"given":"Moshe","family":"Katz","sequence":"first","affiliation":[{"name":"Sheba Medical Center, Ramat Gan 5266202, Israel"},{"name":"Sackler School of Medicine, Tel-Aviv University, Tel Aviv 6997801, Israel"},{"name":"NYU Grossman School of Medicine, New York, NY 10016, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amit","family":"Meitus","sequence":"additional","affiliation":[{"name":"Sackler School of Medicine, Tel-Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Arad","sequence":"additional","affiliation":[{"name":"Sheba Medical Center, Ramat Gan 5266202, Israel"},{"name":"Sackler School of Medicine, Tel-Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Aizer","sequence":"additional","affiliation":[{"name":"NYU Grossman School of Medicine, New York, NY 10016, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eyal","family":"Nof","sequence":"additional","affiliation":[{"name":"Sheba Medical Center, Ramat Gan 5266202, Israel"},{"name":"Sackler School of Medicine, Tel-Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9268-4766","authenticated-orcid":false,"given":"Roy","family":"Beinart","sequence":"additional","affiliation":[{"name":"Sheba Medical Center, Ramat Gan 5266202, Israel"},{"name":"Sackler School of Medicine, Tel-Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2328","DOI":"10.1016\/j.jacc.2019.02.045","article-title":"Arrhythmia-Induced Cardiomyopathy: JACC State-of-the-Art Review","volume":"73","author":"Huizar","year":"2019","journal-title":"J.
