About this study
Official title: Primary Prevention of Sudden Cardiac Death in Real Life: Differences With the Pivotal Studies and Their Consequences
The efficacy of implantable cardioverter-defibrillators (ICD) in primary prevention of sudden cardiac death (SCD) is well demonstrated but pivotal studies have been published more than 10 years ago and implantation's conditions tend to change.
Read the detailed description
The clinical efficacy of implantable cardioverter defibrillator (ICD) as method of primary prevention of sudden cardiac death (SCD) is well demonstrated today. Unfortunately, selection criteria of patients deemed at risk lacks of specificity. For asymptomatic patients with a left ventricular dysfunction (LVEF), current guidelines support implantation of ICD if the LVEF is ≤35%. This target population corresponds to the one studied in the Sudden Cardiac Death in HEart Failure Trial (SCD-HeFT). This trial is 10 years old. The proportion of patients with LVEF > 30% was low (17%) and the analysis of this subgroup showed no decrease in mortality (hazard ratio = 1.08 [0.57-2.07]). That is why the usefulness of ICD in this segment of the population remains a subject of controversy. Moreover, SCD-HeFT did not offer resynchronization therapy despite the fact that more than 40% of patients included had a QRS signal duration ≥120ms.
Conditions for implantation have since changed considerably. The "routine" nature of the implantation procedure and the desire to maximize patient's protection leads us to address for an implantation more easily. As for the resynchronization, it must be attempted in patients with severe heart failure, LVEF ≤35% and QRS sufficiently prolonged.
This suggests that the implanted population is very different nowadays from those from the pivotal studies in terms of mean LVEF and implanted material. However, these two factors are significantly correlated with the risk of SCD... Therefore, the analysis was done on samples of patients who received ICD in primary prevention setting. This study focused on the effect of resynchronization and LVEF at implantation and the subsequent outcome. The results were broadly compared with those of SCD-HeFT.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The efficacy of implantable cardioverter-defibrillators (ICD) in primary prevention of sudden cardiac death (SCD) is well demonstrated but pivotal studies have been published more than 10 years ago and implantation's conditions tend to change.

The record says: finished, as of the sponsor's last update on 9 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mortality from any cause (time frame: up to 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Sep 2016.
