Brief Summary:

Multicentre study with the objective to correlate heart failure hospitalizations and deaths with Home Monitoring data in ICD/CRT-D recipients, in order to identify the combination of Home Monitoring data with the greatest sensitivity and specificity in predicting Heart Failure events.

All data are prospectively collected.

Condition or disease
Heart Failure

Detailed Description:

Home Monitoring remotely provides continuous trends of potential HF-related variables with a sampling interval of 24 hours. Although the predictive value of individual variables may be limited, a proper combination of more variables and their 24-hour sampling may allow developing a HM diagnostic algorithm to accurately predict HF worsening within given time windows.

The objective of this Study is to select the predictive variables which are most likely to be effectively included in a future algorithm.

This is a multicentre, exploratory Study with the objective to prospectively collect follow-up and Home Monitoring data from a population of subjects with indication for ICD and/or CRT-D implantation, to document HF hospitalizations and deaths and to correlate these events with HM data to identify the combination of HM data with the greatest sensitivity and specificity in predicting HF events.

Fifty first hospitalizations for worsening HF (adjudicated by an independent board) are necessary to reach the study objective (Event driven study), which were initially assumed to be generated by 650 patients fulfilling inclusion and exclusion criteria. Sample size estimation has been reviewed after an interim analysis.

Primary Outcome Measures :
  1. First Hospitalization for worsening Heart Failure (HF) [ Time Frame: Participants will be followed for the duration of follow-up, an expected average of 2 years ]

    Hospitalization is defined as a non-elective hospital admission for medical or surgical therapy that results in at least one overnight stay.

    Hospitalization for worsening HF is defined as a hospitalization fulfilling the following criteria:

    1. It was triggered by increased symptom(s) and sign(s) OR objective evidence of worsening HF (LVEF, ECG, or other instrumental evidences);
    2. It required administration or augmentation of intravenous or oral HF medication;

Secondary Outcome Measures :
  1. A composite of death for worsening heart failure, hospitalizations for worsening HF and acute interventions for worsening HF. [ Time Frame: Participants will be followed for the duration of follow-up, an expected average of 2 years ]
