In the case of post-myocardial infarction (MI) patients, no mortality benefit was observed from placing ICDs in patients with reduced ejection fraction until after 40 days post-MI and patient reassessment. This is likely due to the fact that death in the first 40 days post-MI may be attributed to causes other than arrhythmia. [31]
