Predictors of appropriate ICD therapy in Japanese patients with structural heart diseases: A major role of prior sustained ventricular tachycardia in secondary prevention
Abstract:BackgroundImplantable cardioverter defibrillator (ICD) and cardiac resynchronization with a defibrillator (CRT‐D) are established therapies for secondary prevention of sudden cardiac death (SCD) in patients with structural heart disease (SHD), but the rates of subsequent ICD/CRT‐D therapy widely differ among patients with SHD. The aim of this study was to determine clinical factors associated with appropriate therapy for preventing SCD in patients with SHD.MethodsWe enrolled 147 patients with SHD (mean age, 59… Show more
“…A previous episode of sustained VT correlates with high rate of appropriate shocks 433–436 . A higher risk of appropriate therapy was seen in a secondary prevention ICD group when compared with a primary prevention ICD group at 5‐year follow‐up, while the rate of inappropriate therapy was comparable 437 .…”

The categorization for our consensus document should not be considered directly similar to the one used for official society guideline recommendations, which apply a classification (I-III) and level of evidence (A, B, and C) to recommendations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
