However, a recent study revealed a group of Type 1 AMI patients with undetectable myocardial injury on LGE. This study aims to describe these cases in detail and explore possible explanations for this new phenomenon.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>A total of 137 patients diagnosed with either ST-elevation myocardial infarction (STEMI) or non-ST-elevation myocardial infarction (non-STEMI) diagnosed according to the 4th Universal Definition of Myocardial Infarction underwent LGE-CMR after invasive coronary angiography. Fourteen of them (10.2%) showed no LGE and were included in the final study population. Most patients presented with acute chest pain, 3 patients were diagnosed as STEMI, and 11 as non-STEMI. Peak high-sensitive cardiac troponin T ranged from 45 to 1173\u2005ng\/L. A culprit lesion was identified in 12 patients. Severe coronary stenoses were found in five patients, while seven patients had subtotal to total coronary artery occlusion. Percutaneous coronary intervention was performed in 10 patients, while 2 patients required coronary artery bypass grafting and no intervention was required in 2 patients. Cardiac magnetic resonance was performed 30 (4\u2013140) days after the initial presentation. Most patients showed preserved left ventricular ejection fraction on CMR. No alternative reasons for the rise\/fall of high-sensitive cardiac troponin T were found.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The absence of LGE on CMR in patients with Type 1 AMI is a new finding. While insufficient spatial resolution of LGE imaging, delayed CMR performance, spontaneous reperfusion, and coronary collaterals may provide some explanations, further investigations are required to fully understand this phenomenon.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjacc\/zuad128","type":"journal-article","created":{"date-parts":[[2023,10,24]],"date-time":"2023-10-24T22:37:40Z","timestamp":1698187060000},"page":"24-35","source":"Crossref","is-referenced-by-count":3,"title":["Absence of visible infarction on cardiac magnetic resonance imaging despite the established diagnosis of myocardial infarction by 4th Universal Definition of Myocardial Infarction"],"prefix":"10.1093","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1421-474X","authenticated-orcid":false,"given":"Janek","family":"Salatzki","sequence":"first","affiliation":[{"name":"Department of Cardiology, Angiology and Pneumology, Heidelberg University Hospital , Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"},{"name":"DZHK (German Centre for Cardiovascular Research) , Partner Site Heidelberg\/Mannheim, Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evangelos","family":"Giannitsis","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Angiology and Pneumology, Heidelberg University Hospital , Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"},{"name":"DZHK (German Centre for Cardiovascular Research) , Partner Site Heidelberg\/Mannheim, Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anastasia","family":"Hegenbarth","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Angiology and Pneumology, Heidelberg University Hospital , Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthias","family":"Mueller-Hennessen","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Angiology and Pneumology, Heidelberg University Hospital , Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"},{"name":"DZHK (German Centre for Cardiovascular Research) , Partner Site Heidelberg\/Mannheim, Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian","family":"Andr\u00e9","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Angiology and Pneumology, Heidelberg University Hospital , Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"},{"name":"DZHK (German Centre for Cardiovascular Research) , Partner Site Heidelberg\/Mannheim, Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norbert","family":"Frey","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Angiology and Pneumology, Heidelberg University Hospital , Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"},{"name":"DZHK (German Centre for Cardiovascular Research) , Partner Site Heidelberg\/Mannheim, Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6763-6538","authenticated-orcid":false,"given":"Moritz","family":"Biener","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Angiology and Pneumology, Heidelberg University Hospital , Im Neuenheimer Feld 410, 69120 Heidelberg , Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,10,24]]},"reference":[{"key":"2024020909395056000_zuad128-B1","doi-asserted-by":"crossref","first-page":"786","DOI":"10.1161\/01.CIR.56.5.786","article-title":"The wavefront phenomenon of ischemic cell death. 1.
