Implantable cardioverter-defibrillators (ICDs) improve survival in certain high arrhythmic risk populations. However, there are sex differences regarding both the utilization and the benefit of these devices. Using a prospective national ICD registry, we aim to compare the indications for ICD implantation as well as outcomes in implanted women vs. men. All subjects implanted with an ICD or cardiac resynchronization therapy with a defibrillator (CRTD) in Israel between July 2010 and February 2013 were included. A total of 3544 subjects constructed the baseline cohort, of whom 615 (17%) were women. Women had the same age (64 years) and rate of secondary prevention indication (26%) as men. However, women were more likely than men to have significant heart failure symptoms (52 vs. 45%), QRS > 120 ms (41 vs. 36%), and a higher rate of non-ischaemic cardiomyopathy (54 vs. 21%, all P values < 0.05). Using multivariate analysis, women were more likely to undergo CRTD implantation (odds ratio = 1.8, P < 0.01). Follow-up data were available for 1518 subjects with a mean follow-up of 12 months. During follow-up, there were no significant differences among genders in the rate of any single or the combined outcomes of appropriate device therapies, heart failure admissions, or death. First-year re-intervention rate was double among women (5.6 vs. 3.0%, P < 0.01). In real-world setting, women implanted with an ICD differ significantly from men in their baseline characteristics and in the use of CRTD devices. These, however, did not translate into outcome differences.
