Study summary

The objective of this observational study is to assess clinical benefits of innovative features (e.g. Bluetooth technology and smartphone patient applications) in a patient population that is implanted with standard indication for implantable cardiac defibrillator.

Read the detailed description

REACTION is an observational study in which patients will be followed as for clinical practice and no specific study tests/procedures will be perfprmed. After implanting a device, the patient will be assigned to an arm or to the other based on the technology of the device (bluetooth or RF) he/she wears, if he/she gives the consent to partecipate. It is not a randomized study. Patients will be enrolled consecutively until reaching the sample defined for both the arms.

What researchers measure

Primary outcomes

  1. Adherence

    The adherence will be measured through the following endpoints: • Compliance with RM quantified as percentage of patients who registered with the smartphone App

    Time frame: 12 months

  2. Effectiveness

    The effectiveness based on the comparison between the App monitoring and the traditional remote control will be assessed through the following endpoints: • Percentage of time (days) with an active connection between device and the transmitter/smartphone app

    Time frame: 12 months

Secondary outcomes

  1. Clinical benefits in CRT area:

    Association between patient symptom-triggered transmissions and HF events or other clinical events detected by device diagnostics

    Time frame: 12 Months

  2. Clinical benefits in ICD therapies

    Clinical action taken as a result of appropriate or inappropriate ICD therapies

    Time frame: 12 months
