Optimisation of Decision Making for Defibrillator Implantation in Hypertrophic Cardiomyopathy

Condition(s) studied

Study summary

The main objective of the study is to improve implantable cardioverter defibrillator (ICD) implantation decision-making processing relevance by developing a new prediction model of sudden cardiac death (SCD) in hypertrophic cardiomyopathy (HCM), including newly identified potential biomarkers by magnetic resonance imaging (MRI) and genetics, through a prospective nationwide study, multivariate analysis and modelling of an absolute risk.

The secondary objective is to perform a medico-economic analysis of ICD implantation in order to define an optimal rule for ICD implantation in patients with HCM, taking into account the benefits of ICD, adverse effects of ICD and associated costs (cost of quality adjusted life years saved).

Eligibility

Primary outcome measure(s)

• Improvement of the ability to predict major clinical events: C-index comparisons — throughout of the study, an average of 1 year
  Comparisons of the C-index obtained between with the new score and with the different existing scores or algorithms of actual processing used for ICD decision-making. C-index is a discrimination index, which will be determined after multivariate analyses and score modeling, in the case of the new score. This evaluate of the improvement of the ability to predict major clinical events during follow-up will toward to development of a new prediction model in patients with HCM in responding the main objective of the study. Data will be collected are: (composite end point): SCD, aborted sudden death, appropriate therapy of ICD that is a physiological equivalent of SCD.
