We relied on the use of convolutional neural networks as the AI models for the classification of ECG examples. ECGs were also independently evaluated by two expert cardiologists blinded to clinical outcomes; each was asked to determine (a) whether the patient had a STEMI, based on universal criteria or (b) if STEMI criteria were not met, to identify any other ECG finding suggestive of ACOMI. ACOMI was defined by coronary angiography findings meeting any of the following three criteria: (a) total thrombotic occlusion, (b) TIMI thrombus grade 2 or higher + TIMI grade flow 1 or less, or (c) the presence of a subocclusive lesion (> 95% angiographic stenosis) with TIMI grade flow < 3.

He had studied in Paris, Berlin, and other European cities in 1926. Upon his return to Mexico, he founded the Cardiology Service at the General Hospital in Mexico City, the first of its kind in the country. The National Institute of Cardiology of Mexico was inaugurated on April 18, 1944, becoming one of the first cardiology institutes in the world. Chávez explained the purpose of this new institute: \"We were born with the purpose of studying, researching, and controlling heart diseases.\" According to him, the institute should be a place where cardiovascular diseases could be addressed comprehensively, combining clinical practice with research and teaching to provide effective knowledge for patient care and scientific advancement. \"A health center is for the patient, of course; but something more than that is necessary: a great school for doctors, a great laboratory for researchers, and a social instrument of human help,\" he said. This vision was summarized in the words: love and science at the service of the heart. Chávez successfully institutionalized cardiology in Mexico. From its inception, the institute became an internationally recognized center, attracting students from various countries. Alfredo de Micheli noted that under Chávez's influence and example, new institutions emerged in the national medical field and expanded onto the international stage. The institute founded by Chávez became a model for similar institutions on other continents and a driving force in the international cardiology movement. Chávez's legacy was a work of love, intelligence, and culture, dedicated to the heart and the care of humanity.</p>","PeriodicalId":93885,"journal":{"name":"Archivos de cardiologia de Mexico","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142775398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
