BACKGROUND: Remote monitoring (RM) of cardiac implantable electronic devices (CIED) allows for a regular analysis of the occurrence of arrhythmias and functioning of the devices.
AIMS: To date, no study investigated the characteristics of the alert-triggered ultimate transmissions before death, which was the aim of the present analysis.
METHODS: Patients monitored remotely in our center, whose baseline characteristics were obtained from the COMMIT-HF Registry (NCT02536443) were analyzed and divided according to the occurrence of alert transmissions during the RM. In patients who had an alert transmission, the last transmission was analyzed. All RM data were obtained from the software provided by four RM manufacturers.
RESULTS: Of 1271 patients with CIEDs which transmitted at least one message to the RM center, 198 (15.6%) had no alert transmissions, while 1073 (84.4%) had at least one alert transmission. Respective mortality in patients with and without alerts during RM was 29.7% and 12.6%, respectively. In patients who had ever an alert, the last recorded transmission before death was scheduled in 166 patients and alert-triggered in 152 patients. The most frequent alert-triggered last transmissions were atrial fibrillation/flutter (39.4%) and ventricular tachyarrhythmias (26.8%). The median period from the last alert-triggered transmission to death was 10 days.
CONCLUSION: This is the first analysis of the ultimate RM transmissions delivered by CIEDs before death. In approximately 85% of RM patients with CIEDs, at least one alert transmission occurred during the RM, and in patients who had ever an alert, almost half of the last transmissions before death were alert-triggered.
