Is gender a risk factor for mortality or appropriate shock in patients with nonischemic cardiomyopathy who have implantable cardioverter defibrillators?

Abstract

Background: As heart disease is increasingly recognized in women and as important studies have elucidated the benefit of implantable cardioverter defibrillators (ICDs) in patients with nonischemic cardiomyopathy (NICM), little is known regarding the effect of gender difference on arrhythmic risk in this population. We sought to determine if there are gender differences in arrhythmic risk and potential defibrillator benefit in patients with NICM.
