Clinical Trial Summary

Implantable cardioverter-defibrillators (ICD) are currently recommended for the primary prevention of sudden cardiac death (SCD) in patients with a remote (>6 weeks) myocardial infarction (MI) and a low (≤35%) left ventricular ejection fraction (LVEF). Ventricular tachycardia (VT) and/or ventricular fibrillation (VF), which are responsible for most SCDs, result from the presence of surviving myocytes embedded within fibrotic MI-scar. The presence of these surviving myocytes, as well as their specific arrhythmic characteristics, is not captured by LVEF. Hence, the use of LVEF as a unique risk-stratifier of SCD results in a low proportion (17 to 31%) of appropriate ICD device therapy at 2 years. Consequently, most patients with a prophylactic ICD do not present VT/VF requiring ICD therapy prior to their first-ICD battery depletion. Thus, many patients are exposed to ICD complications, such as inappropriate shocks, without deriving any health benefit. Therefore, the current implantation strategy of prophylactic ICDs, based on LVEF only, needs to be improved in post-MI patients.
