The impact of a LTB in terms of long-term clinical outcomes on different myocardial infarct territories has not yet been fully evaluated. From April 2002 to December 2004, consecutive patients with STEMI undergoing percutaneous coronary intervention with drug eluting stent were evaluated. The study sample was stratified in two groups: anterior STEMI and non-anterior STEMI. LTB was considered as a thrombus larger than or equal to 2-vessel diameters, and small thrombus burden less than 2-vessel diameters. Major adverse cardiac events (MACE) were evaluated at 10-year and survival data were collected up to 15-year. A total of 812 patients were evaluated, 6 patients were excluded due to inadequate angiographic images, 410 (50.9%) had an anterior STEMI and 396 (49.1%) a non-anterior STEMI. Patients with LTB had higher rates of 10-year mortality (aHR 2.27, 95%CI 1.42\u20133.63; p\u2009=\u20090.001) and 10-year MACE (aHR 1.46, 95%CI 1.03\u20132.08; p\u2009=\u20090.033) in anterior STEMI, but not in non-anterior STEMI (aHR 0.78, 95%CI 0.49\u20131.24; p\u2009=\u20090.298; aHR 0.71, 95%CI 0.50\u20131.02; p\u2009=\u20090.062). LTB was associated with increased 30-day mortality (aHR 5.60, 95%CI 2.49\u201312.61; p\u2009&lt;\u20090.001) and 30-day MACE (aHR 2.72, 95%CI 1.45\u20135.08; p\u2009=\u20090.002) in anterior STEMI, but not in non-anterior STEMI (aHR 0.39, 95%CI 0.15\u20131.06; p\u2009=\u20090.066; aHR 0.67, 95%CI 0.31\u20131.46; p\u2009=\u20090.316). Beyond 30-day, LTB had no impact on mortality and MACE in both groups. In anterior STEMI, LTB is associated with worse long-term clinical outcomes, this effect was driven by early events.<\/jats:p>","DOI":"10.1007\/s11239-021-02603-3","type":"journal-article","created":{"date-parts":[[2021,11,26]],"date-time":"2021-11-26T06:02:38Z","timestamp":1637906558000},"page":"47-57","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Impact of thrombus burden on long-term clinical outcomes in patients with either anterior or non-anterior ST-segment elevation myocardial infarction"],"prefix":"10.1007","volume":"54","author":[{"given":"Paola","family":"Scarparo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Menno","family":"van Gameren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeroen","family":"Wilschut","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joost","family":"Daemen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wijnand K.","family":"Den Dekker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Zijlstra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolas M.","family":"Van Mieghem","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Diletti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,11,26]]},"reference":[{"issue":"2","key":"2603_CR1","doi-asserted-by":"publisher","first-page":"87","DOI":"10.1093\/eurheartj\/ehy394","volume":"40","author":"FJ Neumann","year":"2018","unstructured":"Neumann FJ, Sousa-Uva M, Ahlsson A, Alfonso F, Banning AP, Benedetto U et al (2018) 2018 ESC\/EACTS Guidelines on myocardial revascularization.
