However, the exact mechanisms leading to death in this new high-risk group need to be investigated in order to develop specific preventive strategies. As known from studies with implantable cardiac monitors (ICM) in post-MI patients with LVEF ≤40% eventual death is often preceded by primarily asymptomatic serious arrhythmic events. These data suggest a potential time frame for pre-emptive interventions in case of arrhythmic events, which could improve outcome.
