Patients' demographics, clinical comorbidities, laboratory tests, and cardiac imaging parameters are recorded. Baseline characteristics are described; the relationship between intracardiac thrombus location and cardiac underlying diseases, New York Heart Association (NYHA) class, and left ventricular ejection fraction (LVEF) are analyzed; and the anticoagulation rate is summarized.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1,248 patients were included in the study. Most patients were men (72.2%) with a mean age of 54 years. The left ventricle is the most frequently involved (66.8%), and the prevalence of left ventricular thrombus is more in patients complicated with coronary artery diseases, ventricular noncompaction cardiomyopathy, and dilated cardiomyopathy (86.3%, 86.4%, and 78.2%, respectively). When combined with atrial fibrillation, atrial flutter, hypertrophic cardiomyopathy, restrictive cardiomyopathy, or valvular cardiomyopathy, the intracardiac thrombus is mostly likely to occur in the left atrium. The incidence rate of left cardiac thrombosis increased with the decline of LVEF, an increase of NYHA class, and enlargement of a cardiac chamber. Overall, the anticoagulation rate was 56.8%, with warfarin still the mainstay drug (45.1%), while the prescription of non-vitamin K antagonist oral anticoagulants rose year by year. As for imaging modalities for thrombus detection and diagnosis, transthoracic echocardiography was the most widely performed (75.1%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study summarizes the underlying disease constitution, thrombus location and related factors, imaging modalities, and antithrombotic profile in HF patients with intracardiac thrombus comprehensively.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fcvm.2022.934160","type":"journal-article","created":{"date-parts":[[2022,10,6]],"date-time":"2022-10-06T13:12:37Z","timestamp":1665061957000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Clinical characteristics of patients with heart failure and intracardiac thrombus"],"prefix":"10.3389","volume":"9","author":[{"given":"Mei","family":"Zhai","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liyan","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Liang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengchao","family":"Tian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lang","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuemei","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boping","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiayu","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiong","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhui","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,10,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e1","DOI":"10.1016\/j.carpath.2011.11.005","article-title":"Intracardiac thrombi in extracardiac disorders: an autopsy study","volume":"21","author":"Vaideeswar","year":"2012","journal-title":"Cardiovasc Pathol."},{"key":"B2","doi-asserted-by":"publisher","first-page":"809","DOI":"10.1016\/j.jcmg.2015.11.029","article-title":"Detection of LA and LAA Thrombus by CMR in patients referred for pulmonary vein isolation","volume":"9","author":"Kitkungvan","year":"2016","journal-title":"JACC: Cardiovasc Imaging."},{"key":"B3","doi-asserted-by":"publisher","first-page":"760","DOI":"10.3760\/cma.j.issn.0253-3758.2018.10.004","article-title":"Chinese guidelines for the diagnosis and treatment of heart failure 2018","volume":"46","year":"2018","journal-title":"Zhonghua xin xue guan bing za zhi"},{"key":"B4","doi-asserted-by":"publisher","first-page":"2476","DOI":"10.1016\/j.jacc.2017.08.074","article-title":"Heart failure with preserved, borderline, and reduced ejection fraction: 5-year outcomes","volume":"70","author":"Shah K","year":"2017","journal-title":"J Am Coll Cardiol."},{"key":"B5","doi-asserted-by":"publisher","first-page":"1772","DOI":"10.1016\/j.ijcard.2012.12.018","article-title":"Is thrombosis a contributor to heart failure pathophysiology?
