The definition, presented at ESC Congress 2026, simplifies the previous numerical system for categorizing MI types, addressing inconsistencies in diagnosis and treatment. The new classification system considers the underlying cause of MI and divides it into three clinical settings: primary MI, secondary MI and procedure-related MI. Each category has specific diagnostic tests and investigations outlined in the new document. The updated definition also aligns with the International Classification of Diseases (ICD) coding, improving public health monitoring and research on less common MI mechanisms, such as spontaneous coronary artery dissection in women.",
  "summary": "When a myocardial infarction, such as a heart attack, occurs, being able to classify its type can improve diagnosis and treatment. For the first time, a universal definition of myocardial infarction has been developed and published by four major cardiac societies: the European Society of Cardiology (ESC), the American College of Cardiology (ACC), the American Heart Association (AHA) and the World…",
