ABSTRACT
AIMS: Cardiac implantable electronic device (CIED) recipients who experienced an ischemic cerebral event may particularly benefit from continuous remote monitoring. We aimed to assess the effect of remote monitoring on the occurrence of 1-year serious adverse events in CIED recipients after ischemic stroke or transient ischemic attack (TIA). METHODS: Patients were eligible if they suffered a TIA/stroke. Study endpoints were all-cause mortality, all-cause hospitalization, and TIA/stroke recurrence. Patients were retrospectively divided according to the presence of remote monitoring for CIED follow-up. RESULTS: From January 2011 to December 2017, 71 CIED recipients were hospitalized in our institution for TIA/stroke: pacemaker (76%), cardiac resynchronization therapy device (17%), or implantable cardioverter defibrillator (7%). Among them, 26 (37%) were remotely monitored (RM-ON), whereas 45 (63%) were followed with conventional in-hospital visits (RM-OFF). No significant differences were found in baseline characteristics between groups. The all-cause mortality and hospitalization rates were significantly lower in the RM-ON group [2.2; 95% confidence interval (CI) 0.8-4.8, and 5.8; 95% CI 3.3-9.4 per 100 patient-months] as compared with the RM-OFF group (8.1; 95% CI 5.2-11.9, and 9.7; 95% CI 6.5-13.9 per 100 patient-months). Despite a similar incidence of new diagnosis of atrial fibrillation, the median time from the arrhythmic episode to the physician evaluation was dramatically lower in the RM-ON as compared with the RM-OFF group [2 (1-3) vs. 78 (64-92) days; Pâ=â0.002]. CONCLUSION: We found that remote monitoring as compared with conventional in-hospital visits may contribute to a better outcome in CIED recipients who had suffered from an ischemic cerebral event.
