For each patient, the same anonymized data (free-text anamnesis, ECG report text, troponin value, and age) will be independently processed by both LLMs via separate API calls with deterministic settings (temperature=0, JSON format). A three-expert consensus HEART score - derived through blinded independent scoring by three emergency medicine physicians with majority-vote adjudication - serves as the reference standard for agreement analysis. Actual 30-day MACE (all-cause death, AMI Type 1\u002F2\u002F4b, unplanned revascularization) determined via national health database and telephone follow-up serves as the outcome for diagnostic accuracy analysis.\n\nA secondary documentation-quality sub-study will quantify how spontaneously Turkish emergency anamnesis notes capture HEART score parameters.",[24,25,26,27],"Emergency Medicine","Artificial Intelligence (AI)","Artificial Intelligence (AI) in Diagnosis","Chest Pain Rule Out Myocardial Infarction",[29,30,31,32,33,34,35,36],"Large Language Model","GPT-4o","Claude Sonnet","Emergency Department","Diagnostic Accuracy","Medical Informatics","Physician vs AI","HEART score","RECRUITING","2026-06-22",{"date":40,"type":41},"2026-06-23","ACTUAL",{"date":43,"type":20},"2026-06",{"date":45,"type":20},"2027-06",{"name":47,"class":48},"Marmara University Pendik Training and Research Hospital","OTHER",1,{"id":51,"slug":4,"hasResults":10,"nctId":52,"briefTitle":53,"officialTitle":54,"acronym":55,"eligibilityCriteria":56,"healthyVolunteers":10,"sex":16,"minAge":17,"maxAge":4,"enrollmentInfo":57,"targetDuration":4,"studyType":59,"phases":60,"briefSummary":62,"conditions":63,"keywords":65,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":72,"lastUpdatePostDateStruct":73,"startDateStruct":75,"completionDateStruct":77,"leadSponsor":79,"locationsCount":81},"100595087","NCT07027891","The Rule-Out Acute Myocardial Infarction Using Aritifical Intelligence Electrocardiogram (ROMIAE) 2 Trial","ROMIAE 2 Trial: Randomized Controlled Trial for Managing Suspicious Acute Myocardial Infarction in ED Using AI-ECG","ROMIAE 2","Inclusion Criteria:\n\n* chest pain\n* suspicious of acute myocardial infarction\n\nExclusion Criteria:\n\n* STEMI\n* Revisit of same symptoms within 1 week\n* traumatic chest pain\n* Pneumothorax\n* Transferred from other hospital diagnosed of AMI\n* Cardiac arrest\n* Chest pain of clearly non-cardiac etiology\n* declined to participate in the study",{"count":58,"type":20},4670,"INTERVENTIONAL",[61],"NA","This study is to see whether the AI ECG assisted protocol is as safe and efficacious as conventional protocol in early triage of suspected myocardial infarction.",[64,27],"Myocardial Infarction (MI)",[66,67,68,69,70,71],"chest pain, suspicious myocardial infarction","artificial intelligence","electrocardiogram","emergency department","acute coronary syndrome","AI\u002FML-enabled SaMd","2026-06-09",{"date":74,"type":41},"2026-06-11",{"date":76,"type":41},"2025-07-01",{"date":78,"type":20},"2028-02-28",{"name":80,"class":48},"CHA University",12,""]
