• Study Type: interventional
• Target: N/A
• Locations: 0 countries

Brief Summary

The objective of the study is to demonstrate that in post-MI patients with preserved LVEF\>35% but high risk for SCD according to a personalised risk score, the implantation of an ICD (index group) is superior to optimal medical therapy (control group) with respect to all-cause mortality.

Implantable cardioverter-defibrillator (ICD) DEVICE

An ICD consists of an electronic medical device and electrode leads. The surgery can be performed in local anaesthesia, but a short general anaesthesia is required if the ICD has to be tested giving the patient an electric shock. Besides the possibility to shock during arrhythmias the ICD can potentially terminate ventricular tachycardias by rapid pacing for short periods (small bursts of pacing). The subcutaneous defibrillator is an established and valid alternative to the conventional ICD for the preven-tion of SCD. According to current guidelines, the subcutaneous defibrillator should be considered as an alternative to transvenous defibrillators in patients with an indication for an ICD when pacing therapy for bradycardia support, cardiac resynchronisation or antitachycardia pacing is not needed.

• Signed informed consent.

You may not qualify if:

• Class I or IIa indication for implantation of an ICD for secondary prevention of sudden cardiac death and ventricular tachycardia (according to the 2015 ESC Guidelines for the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death, see Appendix V).
• Ventricular tachycardia induced in an electrophysiologic study.
• Unexplained syncope when ventricular arrhythmia is suspected as the cause of syncope.

• Carrying any implanted cardiac pacemaker, defibrillator or CRT device.
• Violation of instruction for use (IFU) of the selected ICD device by at least one of the random group treatments.
• Hospitalised with unstable heart failure with NYHA class IV within 1 month prior to enrolment.
• Acute coronary syndrome or cardiac revascularization therapy by coronary angioplasty or coronary artery bypass grafting within 3 months prior to enrolment.
• Cardiac valve surgery or percutaneous cardiac valvular intervention such as transcatheter aortic valve replacement or transcatheter mitral valve repair performed within 3 months prior to enrolment.
• On the waiting list for heart transplantation.
• Any known disease that limits life expectancy to less than 1 year.
• Participation in another clinical trial, either within the 3 months prior to enrolment or still on-going (participation in sub-studies connected to this trial is permitted).
• Previous participation in PROFID-Preserved.
• Drug abuse or clinically manifest alcohol abuse.
