A total of 433 patients were followed for 27 months in 43 centres after having been randomized to remote monitoring (active group) or in-clinic follow-up (control group). A first in-clinic ICD follow-up within 1 to 3 months after implantation was scheduled for all patients. Then, in the active group, patients were seen in the ambulatory department only once a year, unless an anomalous ICD function or an event of clinical concern was reported by remote monitoring and required an additional in-clinic visit. In the control group, the patients were followed in the ambulatory department at 6-month intervals.
Importantly, the ECOST trial is the first trial to show a 52% reduction of the number of patients with inappropriate shocks and a 72% reduction in the risk of hospitalizations related to inappropriate shocks, clearly underlining the effectiveness of home monitoring in ICD recipients. In addition, ECOST shows a 76% reduction in the number of charged shocks with a significant impact on ICD battery longevity.
ECOST has clinically proven with a non inferiority hypothesis that remote ICD monitoring is a safe alternative to conventional follow-up in terms of all cardiac and device related major adverse events and all cause deaths. These results are consistent with, and extend, previous findings by clearly demonstrating the safety of long-term remote ICD monitoring
