Age-related progression of myocardial dysfunction in patients with Duchenne muscular dystrophy assessed by cardiac magnetic resonance tissue tracking: a case-control study

Cardiovascular complications are the primary cause of mortality in patients with Duchenne muscular dystrophy (DMD). However, the dynamic progression underlying myocardial damage in DMD has not yet been fully elucidated. This study aimed to quantitatively assess myocardial dysfunction in patients with DMD across different age groups via cardiac magnetic resonance (CMR) tissue tracking technology.
