However, there are gender differences regarding both the utilization and benefit of these devices. In this prospective CIED registry, we aim to appraise the gender differences in CIED utilization in China. Methods Twenty centers from 14 provinces in China were included in our registry study. All patients who underwent a CIED implantation in these twenty centers between Jan 2015 and Dec 2016 were included. Results A total of 8570 patients were enrolled in the baseline cohort, including 7203 pacemaker, 664 implantable cardiac defibrillators （ICD） implants and 703 cardiac resynchronization therapy device （CRT/D）. Totally, 4117 （48.0%） CIED patients were female, and more than 59% pacemaker patients were female, but women account only one third of ICD or CRT/D implantation in this registry. There were significant differences between genders at pacemaker and ICD indications. Female was more likely received a pacemaker due to sick sinus syndrome （SSS） （63.9% vs. 51.0%, P 〈 0.001）. Female patients receiving an ICD were more likely due to cardiac ion channel disease （29.2% vs. 4.2%, P 〈 0.001）. The percentage of utilization of dual-chamber pacemaker in female patients was significantly higher than male （85.3% vs. 81.1%, P 〈 0.001）. But male patients were more likely received a cardiac resynchronization therapy devices with defibrillator than female （56.5% vs. 41.9%, P = 0.001）. In pacemaker patient, male was more likely to have structure heart disease （31.3% vs. 28.0%, P = 0.002）. In ICD patient, male patients were more likely to have ischemic heart disease （48.2% vs. 29.2%, P 〈 0.001）. The mean age of women at the time of CRT/D implantation was older than men （P = 0.014）. Nonischemic cardiomyopathy （70.9%） was the most common etiology in the patients who underwent the treat？ment of CRT/D, no matter male or female. Conclusions In real-world setting, female do have different epidemiology, pathophysiology and clinical presentation of many cardiac rhythm disorders when compared with male, and all these factors may affect the utilization of CIED implantation. But it also possibility that cultural and socioeconomic features may play a role in this apparent discrimination.展开更多
