Clinical Trial Summary

The prognostic relevance of isolated non-ischemic LGE (i.e. with no underlying "labelled" cardiomyopathy) is unclear, and current guidelines to not state on the clearance of athlete with this type of findings as regards to competitive or intense sport practice.

The principal objective of the study is to evaluate during a five-years follow up, the clinical outcome of athletes with this kind of findings. The secondary objective is the determination of prognostic factors. The management and follow-up of the athletes will be let at the appraisal of each center.


Description:

The presence of a scar, assessed by late gadolinium enhancement (LGE) on cardiac resonance imaging (CMR), is associated with a poor prognosis in patients with ischemic heart disease or cardiomyopathy. But the prognostic relevance of isolated non-ischemic LGE (i.e. with no underlying "labelled" cardiomyopathy) is unclear, and current guidelines do not state on the clearance of athlete with this type of findings as regards to competitive or intense sport practice.

The objective of the study is to evaluate the clinical outcome of athletes with isolated non-ischemic LGE with no underlying "labelled" cardiomyopathy during a five-years follow-up. The secondary objective is the determination of prognostic factors based on the baseline inclusion data: indication of CMR (i.e. symptoms, abnormal ECG, presence and morphology of arrhythmias, abnormal echocardiography); localization and amount of LGE, left and right ventricular geometry and function, characteristics of sport practice (amount, type, competition).

The management of the athletes will be let at the appraisal of each centre, as regards to the initial assessment, the follow-up and the medical clearance for competitive sports participation. Nevertheless, due to the absence of consensus, we propose that the patient should at least undergo clinical examination, ECG, echocardiography, cardiopulmonary exercise test (CPET) and holter ECG each year. A CMR should be performed at one and five years.


Recruitment information / eligibility

Status Recruiting
Enrollment 200
Est. completion date October 5, 2025
Est. primary completion date October 5, 2020
Accepts healthy volunteers No
Gender All
Age group 15 Years and older
Eligibility Inclusion Criteria:

- Any athlete, aged of more than 15 years, symptomatic or not,

- in whom non-ischemic LGE with no underlying "labelled" cardiomyopathy is detected on CMR. Scare of an acute myocarditis will also be included.

Athletes will be defined by a practice of =4 hours/week of sport activity and/or competitive sport activity at the time of the assessment which triggered the realization of the 1st CMR.

Exclusion Criteria:

- Athletes with any unequivocal cardiac disease that might explain the LGE (i.e. hypertrophic cardiomyopathy, ischemic cardiac disease). In case of borderline or doubtful diagnosis the athlete can still be included (for example an athlete with a dilated LV and borderline function, or with borderline wall thickness).

- Patients who refuse their participation in the study.

- Patients under legal protection or deprived of their liberty.

Outcome

Type Measure Description Time frame Safety issue
Primary Occurrence of a major cardiac event During a follow-up of 5 years, occurrence of a major cardiac event defined by either: death, death of cardiovascular cause; hospitalization for cardiac event; any major arrhythmic event defined by arrhythmic cardiac arrest, sustained ventricular tachycard five years after inclusion
Secondary Morphological end-point Alteration of left ventricular (LV) function defined by a decrease in LVEF as compared to the initial evaluation (=10%, or occurrence of a new wall motion abnormality assessed the same imaging technic, i.e. echocardiography or CMR) five years after inclusion
Secondary Functional end-point alteration of exercise capacity, defined by a reduction =10% of peak VO2, not explained by training changes five years after inclusion
Secondary Arrhythmic end-point Occurrence of a non-sustained VT (NSVT), defined as a tachycardia originating in the ventricle >100 beats/min and lasting =3 beats but less than 30 seconds. five years after inclusion
