Brief Summary

The prospective EUTrigTreat multi-center study is an observational, advanced diagnostics and genetic risk stratification trial in patients with standard indications for ICD treatment, with and without myocardial infarction in their history. Its aims are fourfold: 1) To accurately risk stratify a large cohort of implantable cardioverter-defibrillator (ICD) patients for ICD shock risk and mortality using traditional risk markers as well as genetic markers 2) To find a link between repolarization biomarkers and genetic markers of calcium metabolism. 3) To compare invasive and noninvasive electrophysiologic (EP) testing systematically 4) To assess temporal changes of typical noninvasive risk stratifiers and their prognostic implication. In five European academic clinical centers, 700 ICD patients are prospectively enrolled (optionally the number of enrolled patients may be expanded to 1000 patients). Comprehensive non-invasive risk stratifying ECG diagnostics including beat-to-beat variability of repolarization (BVR) are applied, and candidate genes associated with malignant arrhythmias are analyzed. Programmed electrical stimulation is performed to test for inducibility of malignant ventricular arrhythmias and BVR. In a subset of patients, electrophysiologic studies include recording of monophasic action potentials (MAP) from the right ventricle for assessment of restitution properties. Non-invasive risk stratifying ECG methods are repeated annually. Outcome (mortality, ICD shocks) will be assessed until September 2014.

Study Arms (2)

Invasive EP Study Group

200 patients are studied before clinically indicated (according to AHA/ACC/ESC guidelines) first ICD implantation or ICD exchange. Invasive EP study is performed to test inducibility of malignant arrhythmia. In addition MAP recordings are performed for measurements of restitution properties. Pacing is done for 12-lead ECG and MAP recordings for analysis of BVR and TWA, if applicable.

Noninvasive EP Study Group

The assignment of patients to the invasive and noninvasive EP groups does not occur by randomization or for intervention. In the noninvasive EP study group, 500 patients with chronically implanted ICD (\>3 month after implantation) are investigated using non-invasive EP study via ICD programmer. Programmed electrical stimulation is performed to test for inducibility of malignant arrhythmia. In addition pacing is done for measurements of BVR from the 12-lead ECG.

You may qualify if:

  • Standard indication for ICD treatment according to ACC/AHA/ESC guidelines for primary or secondary prevention of SCD
  • Age ≥ 18 years
  • Nonischemic cardiomyopathies: DCM, HCM/HOCM, ARVC or
