Heart failure patients with implantable defibrillators often visit the hospital for unscheduled examinations, placing a great burden on healthcare providers. Device manufacturers offer a technology for remote defibrillator monitoring with the purpose of allowing physicians to remotely access patients' data and reducing unnecessary routine and interim visits. The Evolution of Management Strategies of Heart Failure Patients With Implantable Defibrillators (EVOLVO) study was a multicenter randomized trial designed to assess whether remote management can reduce emergency healthcare use in heart failure patients implanted with defibrillators endowed with specific diagnostic features compared with standard management consisting of scheduled in-office visits and patient response to audible alerts. Over 16 months, the rate of emergency department or urgent in-office visits for heart failure, arrhythmias, or device-related events decreased by 35% and total healthcare visits were 21% less frequent with remote monitoring.
