We present two cases of young athletes with MI. They did not have previous symptoms, traditional risk factors, or a family history of MI. One case involves a 37-year-old male amateur athlete who experienced two MI following intense physical exertion, likely due to the erosion of an insignificant atherosclerotic plaque caused by a sudden increase in blood pressure during exercise. The second case describes a 36-year-old male semi-professional runner who collapsed at the finish line of a half-marathon and was diagnosed with hypertrophic cardiomyopathy. The heart\u2019s oxygen demand\u2013supply mismatch during intensive exercise led to MI. Following the case presentation, we discuss the most common causes of MI in young athletes and their mechanisms, including spontaneous coronary artery dissection, chest trauma, abnormalities of the coronary arteries, coronary artery spasm, plaque erosion, hypercoagulability, left ventricular hypertrophy, and anabolic steroids use.<\/jats:p>","DOI":"10.3390\/diagnostics13152473","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T01:03:25Z","timestamp":1690333405000},"page":"2473","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Myocardial Infarction in Young Athletes"],"prefix":"10.3390","volume":"13","author":[{"given":"Mariusz","family":"Dotka","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Poznan University of Medical Sciences, 61-701 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9586-0163","authenticated-orcid":false,"given":"\u0141ukasz A.","family":"Ma\u0142ek","sequence":"additional","affiliation":[{"name":"Faculty of Rehabilitation, University of Physical Activity in Warsaw, 01-968 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e618","DOI":"10.1161\/CIR.0000000000000617","article-title":"Fourth Universal Definition of Myocardial Infarction (2018)","volume":"138","author":"Thygesen","year":"2018","journal-title":"Circulation"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2053","DOI":"10.1056\/NEJMra1606915","article-title":"Acute myocardial infarction","volume":"376","author":"Anderson","year":"2017","journal-title":"N.
