About

This is a multicentre European double-blind,randomized and controlled trial with 2 parallel groups (1 study medication, 1 placebo) in order to analyse the impact of ACE inhibitors (ACEi) in subjects who carry a mutation but have not yet developed DCM (dilated cardiomyopathy).

Objective of the trial: Study the impact of ACE inhibitors (ACEi) in subjects who carry a mutation (leading to a genetic form of heart failure) but have not yet developed DCM.

Context. Dilated Cardiomyopathy (DCM) is one of the leading causes of Heart Failure due to systolic dysfunction and at least 30% of DCM are of familial/genetic origin, usually with autosomal dominant inheritance, and underlying genes and mutations are increasingly identified. Familial Dilated Cardiomyopathy (fDCM) is characterized by age-related penetrance (or delayed-onset), that means that the cardiac expression of the disease (echocardiographic abnormalities) is usually absent for a long period and progressively appears with advanced age, usually after 20 years of age

Hypothesis : ACEi may delay or prevent the occurrence of DCM in these subjects (pre-clinical stage).

Expected results: If the hypothesis is confirmed, and as a consequence, the knowledge derived from basic research (genes identification in DCM) will be translated into clinical practice (early identification of subjects at high risk of developing heart failure through predictive genetic testing) with the development of new therapeutic management (early ACEi) that will help to decrease the morbidity and mortality associated with the disease. This will constitute a paradigm of the development of preventive medicine thanks to the development of genetics in the cardiovascular field.

Subjects who are concerned are ≥18 years of age and ≤60 years, carry a mutation responsible for DCM and are at a preclinical stage of the disease. Total duration of treatment (perindopril versus placebo) is 3 years. A total number of 200 participants will be enrolled (100 in each group) in 7 centres.

Inclusion criteria

Age: ≥18 years and ≤60 years
At least one family member should have a clinical diagnosis of dilated cardiomyopathy (LVEF<45% and LVEDD>112%)and should not be considered as the burn-out phase of another cardiomyopathy (such as HCM, ARVC). LV noncompaction may co-exist with DCM in this patient.NB:in a patient with a mutation in LMNA gene, LVEDD may be normal whereas EF is markedly reduced, so that only a reduced LVEF is mandatory(LVEF<45%).
Carriers of the mutation that has been identified in the family as associated with DCM, and who have received appropriate genetic counselling before and after the announcement of the genetic result. The mutation within the family should be considered as disease-causing.
No obvious DCM as assessed by diagnostic criteria indicated elsewhere on echocardiography (WHO & Mestroni et al. 1999 and Mahon et al. 2005: references 3 and 9): LVEF <45% and enlarged LVEDD (>112% of predicted value according to age,BSA).
Presence of minor LV abnormality:
- isolated LVEDD > 112% (Henry Formula)
- or reduced systolic dysfunction: 45% < LVEF < 55%, as assessed on echocardiography.
Able to provide informed consent, and signed informed consent.
Able to understand and accept the study constraints
For some European countries (such as France and Spain): participants (by themselves) should have medical health care coverage to be included in a research study

Exclusion criteria

Other disease or factor that can cause minor LV abnormalities, such as cardiotoxic treatment or significant blood hypertension (with uncontrolled blood pressure or significant hypertrophy on echocardiography).
Contraindication to ACE inhibitor
Participants who are already treated with ACE inhibitor, sartan or aldosterone receptor antagonists (for various reason such as arterial hypertension) can not be included in this study, unless they have been off these drugs for a period of 6 weeks before inclusion.
Impaired renal function: estimated Glomerular Filtration Rate (eGFR), using MDRD formula, < 60 ml/mn/1.73m2.
Baseline serum potassium >5.5 mmol/L.
Pregnant, parturient or breastfeeding woman or woman of childbearing potential not under effective contraception or planned pregnancy.
Participation in another therapeutic trial in the previous 3 months
Participants treated with lithium
Participant under legal guardianship
