End date March 2017
Trial size 922 participants
Trial identifier NCT01836510, TA100


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.

Study Design

Observational model cohort
Time perspective prospective

Primary Outcomes

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

Secondary Outcomes

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

Eligibility Criteria

All participants at least 18 years old.

Inclusion Criteria: - Left Ventricular Ejection Fraction (LVEF) ≤ 35% - NYHA Class II or III Heart Failure - Men and women 18 years of age or older - Understand the nature of the procedure - Give written informed consent Exclusion Criteria: - No indication or contraindication for ICD or CRT-D therapy - Permanent AF - NYHA Class IV Heart Failure - Subjects with irreversible brain damage from preexisting cerebral disease; - Subjects with acutely decompensated heart failure - Expected heart transplantation within next six months or planned cardiac surgery within next 3 months - Have a life expectancy of less than six months - Presence of any disease, other than the subject's cardiac disease associated with a reduced likelihood of survival for the duration of the trial, (e.g. cancer) - Unstable geographical residence (unable to anticipate to be resident in the area of the referring participating centre during the study period) and/or GSM-free residence - Subjects who were not been implanted with ICD or CRT-D devices compatible with HM transmissions - Age <18 years - Pregnancy

Additional Information

Official title Selection of Potential Predictors of Worsening Heart Failure
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.
