Study of Personalized Allocation of Defibrillators in Non-ischemic Heart Failure (SPANISH-1)
Consorcio Centro de Investigación Biomédica en Red (CIBER)
900 participants
Sep 6, 2023
INTERVENTIONAL
Conditions
Summary
Prospective, randomised, multicentre, open-label study to assess the non-inferiority of a personalised precision strategy for Sudden Cardiac Death (SCD) prevention in patients with non-ischemic dilated cardiomyopathy with Left Ventricular Ejection Fraction (LVEF) ≤35%
Eligibility
Inclusion Criteria6
- Age ≥ 18 years at the time of screening.
- Previously established diagnosis of Non-ischemic DCM
- Optimised medical treatment at maximum tolerated doses for at least 3 months prior to the screening date.
- NYHA functional class II-III.
- LVEF ≤ 35% documented by CMR as study procedure.
- Life expectancy greater than 12 months.
Exclusion Criteria7
- History of coronary artery disease justifying the presence of ventricular dysfunction, defined as: history of coronary revascularisation or presence of significant coronary stenosis (≥50% in left main or ≥70% in a major epicardial artery) on invasive or non-invasive coronary angiography (coronary CT)
- Left ventricular dysfunction attributed to congenital heart disease, valvular disease, alcohol abuse or chemotherapy.
- Hypertrophic or infiltrative cardiomyopathy, active myocarditis or constrictive pericarditis.
- History of recovered sudden death or sustained ventricular tachycardia.
- NYHA functional class IV.
- Waiting list for cardiac transplantation in emergency 0.
- Receiver of a solid organ transplant (lung, liver, heart or kidney).
Interventions
ICDs will be implanted in all patients according to current recommendations
Patients allocated to the intervention strategy will receive an ICD according to genetic and CMR results. ICD implantation criteria in patients allocated to the personalised strategy group will be the presence of either a DCM-causing pathogenic or likely pathogenic genetic variants or LGE in CMR. Patients without DCM-associated genetic variants and without LGE on CMR will not receive standard treatment but an ICD will not be implanted on them.
