All-Cause Mortality Primary · Outcome measured timeframe includes all available follow-up. Median 61 (4, 71) months.

The original study design was event driven with the end date expected to be based on crossing the statistical boundary. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years. The outcomes will be analyzed but are no longer statistically powered for conclusions.

Sponsor's own description

The MADIT S-ICD trial was designed to evaluate if subjects with a prior myocardial infarction, diabetes mellitus and a relatively preserved ejection fraction of 36-50% will have a survival benefit from receiving a subcutaneous implantable cardioverter defibrillator (S-ICD) when compared to those receiving conventional medical therapy. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years.
