Summary

Anorexia nervosa is an eating disorder occurring in adolescent females, characterized by voluntary dietary restriction, intense fear of gaining weight, and disturbed body image perception. Anorexia nervosa is characterized by the potential severity of its prognosis. While complete remission occurs in about 50% of cases, up to 20% of patients will develop a chronic relapsing form that leads to social disintegration. Moreover, anorexia nervosa has the highest mortality rate among psychiatric diseases with a risk of death of up to 10%. 30% of deaths in anorexia nervosa are attributed to cardiac complications remaining insufficiently described, and their screening at a preclinical stage is still poorly codified. Echocardiography findings show reduced left ventricular mass, pericardial effusion or mitral valve prolapse ; in addition, systolic function appears to be preserved whereas a global diastolic dysfunction, estimated with trans-mitral flow and global longitudinal strain. While the interest of cardiac echography has been well established, only one study used MRI as a means of cardiac evaluation in anorexia nervosa: interestingly, local myocardial fibrosis is pointed and could potentially contribute to cardiac rhythm disorders. No study has yet used T1-Mapping MRI to evaluate if diffuse myocardial fibrosis is prevalent in this population group.

The investigators conduct a transversal, observational, monocentric study whereby malnourished patients with anorexia nervosa and age- and sex- matched, normal weight, healthy volunteers will undergo a gadolinium-enhanced cardiac MRI. The primary objective of this study is to evaluate and compare the frequency of cardiac fibrosis in those populations. Other cardiac MRI parameters will be described and compared as secondary objectives. Moreover, non-cardiac parameters evaluated by MRI such as adipose tissue distribution in anorexia nervosa patients compared with controls.

In addition, patients with anorexia nervosa, a clinical, morphological and biological evaluation, including anthropometric parameters, biphotonic absorptiometry, resting electrocardiogram, cardiac echography and classical biological markers of malnutrition, will be done.
