MEdical Treatment in Idiopathic Ventricular Fibrillation Patients

Denmark218 participantsStarted 2018-05-01

Plain-language summary

A person who has experienced a cardiac arrest with no apparent cause is at risk of having recurrent cardiac arrest. Hence an implantable cardioverter-defibrillator (ICD) is recommended on empirical grounds. Today, there is no uniform way of approaching prevention of recurrence in idiopathic ventricular fibrillation (IVF) patients, beside ICD implantation. Better reatment and risk stratification tools are needed Medical treatment in these patients has never been assessed systematically, but at least some patients with no apparent diagnosis are on betablocker treatment. It is not known if low-doselow dose betablocker treatment is beneficial in these patients. This study investigates the effect of betablocker treatment to reduce arrhythmic burden in IVF patients. No predictors for appropriate ICD therapy have been identified in patients with IVF. It is also explored if toxicological and/or genetic profiles, together with in depth machine learning simulation data on repolarization patterns from IVF-ECGs compared to controls, can be used as risk stratification tools. Lastly, QOL in IVF patients and the impact of beta blocker treatment will be investigated.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
