Benefit of Implantable Cardioverter Defibrillator Use in Japanese Patients Based on Modified MADIT-ICD Benefit Score

ESC Heart FailPublished Retrospective cohort study

Authors' conclusion

The modified MADIT-ICD benefit score may be useful for stratifying ICD candidates in the Japanese population.

Study context

Population
Japanese patients with implantable cardioverter defibrillator (ICD) implantation as primary prophylaxis
Participants
167 patients
Exposure
Modified MADIT-ICD benefit score risk groups
Outcome
Appropriate ICD therapy and non-arrhythmic death (all-cause death without appropriate ICD therapy)

Main finding
