Improve the Prevention of Sudden Cardiac Arrest in Patients With Post-Acute Myocardial Infarction

Background: Implantable cardioverter-defibrillator (ICD) implantation to prevent sudden cardiac death (SCD) in post-myocardial infarction (MI) patients varies by geography but remains low in many regions despite guideline recommendations. Objectives: This study aimed to characterize the care pathway of post-MI patients and understand barriers to referral for further SCD risk stratification and management in patients meeting referral criteria. Methods: This prospective, nonrandomized, multi-nation study included patients ≥18 years of age, with an acute MI ≤30 days and left ventricular ejection fraction <50% ≤14 days post-MI. The primary endpoint was defined as the physician's decision to refer a patient for SCD stratification and management. Results: In total, 1,491 post-MI patients were enrolled (60.2 ± 12.0 years of age, 82.4% male). During the…
