Registered outcomes8
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Composite of Recurrent VT or VT storm | Primary outcome will be assessed at 3-, 6-, 12-, 18-, 24-, 30-, 36- months post-randomisation. VT/VT Storm events after the 30-day treatment 'blanking' period after treatment initiation will be included. | VT (detected by cardiac device as lasting ≥30 seconds or shorter in duration if treated by the ICD). VT storm (three or more documented episodes of VT within 24 hours or incessant VT). |
| Primary | Death | Primary outcome will be assessed at 3-, 6-, 12-, 18-, 24-, 30-, 36- months post-randomisation. Death events at any time after randomisation will be included. | Death (at any time) due to any cause. |
| Secondary | Recurrent sustained VT | Outcome will be assessed at 3-, 6-, 12-, 18-, 24-, 30-, 36- months post-randomisation. VT events will be included after the 30-day treatment 'blanking' period after treatment initiation. | Recurrent sustained VT detected by implanted cardioverter defibrillator (ICD) (VT identified and treated by the ICD with anti-tachycardia pacing (ATP) and/or internal ICD delivered shock or ≥30 seconds of VT if untreated by ICD) |
| Secondary | VT storm | Outcome will be assessed at 3-, 6-, 12-, 18-, 24-, 30-, 36- months post-randomisation. VT storm events will be included after the 30-day treatment 'blanking' period after treatment initiation. | Three or more documented episodes of VT within 24 hours or incessant VT |
| Secondary | VT burden | 6 months after randomisation, with a 30-day treatment 'blanking' period after treatment initiation; and 6 months before randomisation | VT burden (number of episodes of VT in the preceding 6 months compared to the 6 months after randomisation and therapy) |
| Secondary | Cardiovascular hospitalisation | Outcome will be assessed at 3-, 6-, 12-, 18-, 24-, 30-, 36- months post-randomisation. Events will be included after the 30-day treatment 'blanking' period after treatment initiation. | All cardiovascular hospitalisation; heart failure; hospitalisation for arrhythmia |
| Secondary | Mortality | Outcome will be assessed at 3-, 6-, 12-, 18-, 24-, 30-, 36- months post-randomisation. Events will be included at any time after randomisation. | All-cause mortality; cardiovascular mortality; non-cardiac death |
| Secondary | Effect of intervention on ventricular function | Outcome will be assessed at 3-, 6-, 12-, 18-, 24-, 30-, 36- months post-randomisation. Events will be included after the 30-day treatment 'blanking' period after treatment initiation. | Effect of intervention on ventricular function as assessed by transthoracic echocardiography from baseline to 6-, 12-, 24- and 36-months' post intervention |
