  • Descrição: Abstract Background Patients with chronic right ventricular (RV) pacing are at an increased risk of heart failure. Previous studies have indicated that cardiac resynchronization therapy (CRT) is underused in this setting, and that there may be sex‐based differences in both CRT use and clinical outcome. Objective To evaluate sex‐based differences in CRT use and clinical outcome for patients with new‐onset heart failure post RV pacing. Methods Data from the Swedish pacemaker registry was matched with data from the national death and disease registries. Patients with de novo pacemaker implant due to AV block during the period 2005–2020 were included. New‐onset heart‐failure within two years post‐implant was evaluated, primary outcome was all‐cause mortality. Results In all, 30183 patients (37% female) were included. Women were on average 3 years older, but had less comorbidities than men. Median follow‐up time was 4.5 [2.0–8.0] years. Women had better age‐ and comorbidity‐adjusted survival (HR 0.78 [0.73–0.84], p  < .001). For the 3560 patients (12.4% men and 10.7% women, p  < .001) who were diagnosed with new‐onset heart failure, 5‐year mortality was similar for men and women (50% vs. 48%, p  = .29). However, women were less likely to receive CRT‐upgrade (3.8% vs. 9.1%, p  < .001), and those who did were almost ten years younger than the men. Conclusion Women with pacemaker due to AV block are older but have less comorbidities than men. They are less likely to develop new‐onset heart failure, but also less likely to receive a CRT upgrade if they do develop heart failure. Increased awareness of the positive effects of CRT upgrade and potential sex‐ and age‐based discrimination is warranted.
