Abnormal circumferential strain can be detected early in patients with DMD, despite the presence of normal ejection fraction. (Ref: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2709409/) Regular cardiac function evaluations can lead to timely treatment which may slow the progression of cardiac fibrosis.
