Trial summary

Implantable cardioverter-defibrillator (ICD) therapy reduces mortality in patients with chronic heart failure and reduced left ventricular ejection fraction (LVEF) <36%. Nevertheless, patient selection for ICD therapy based on LVEF and NYHA functional class alone seems to have a low specificity and sensitivity: In 100… Read more about this study

About this study

Official title: Evaluation of Novel Biomarkers to Improve Risk Stratification and Patient Selection in ICD Therapy

Implantable cardioverter-defibrillator (ICD) therapy reduces mortality in patients with chronic heart failure and reduced left ventricular ejection fraction (LVEF) <36%. Nevertheless, patient selection for ICD therapy based on LVEF and NYHA functional class alone seems to have a low specificity and sensitivity: In 100 patients treated, the SCD-HeFT study prevented 7 deaths in 5 years. Therefore 93 patients have a risk of adverse effects, such as operation risk, infection, pneumothorax, lead dislocation, and inadequate icd therapy. On the other hand, patients with advanced or end stage heart failure might rather die off progressive heart failure death and thus not benefit from ICD therapy.

It therefore seems appropriate and necessary to improve the individualized risk stratification in these patients. The aim of this study is to evaluate multiple cardiac biomarkers in a model predicting ventricular arrhythmias in patients on ICD therapy.

Read the detailed description

Patients having or getting an ICD in the Dept. of Cardiovascular Medicine of the Hannover Medical School will be recruited in the next 2 years. Blood samples of all patients will be obtained at inclusion and at 6 months follow-up. Patients will be followed-up for 1-2 years after inclusion.

Questions about this trial

What is this clinical trial studying?

An observational study of Ventricular Arrhythmias and Cardiac Death, run by Hannover Medical School at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Feb 2021. 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 Germany. 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?

ICD therapy (time frame: 2 years). 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 11 Feb 2021.
