To the Editors, Thank you for your attention and interest in our manuscript.1 Duchenne muscular dystrophy (DMD) is a severe, progressive, muscle-wasting disease that leads to difficulties with movement and eventually to the need for assisted ventilation and premature death. The disease is caused by mutations encoding dystrophin that abolish the production of dystrophin in muscle. Dystrophin is a cytoskeleton protein. That is why DMD primarily affects muscle cells and it does not affect vascular structures. Therefore, no association of spontaneous coronary artery dissection (SCAD) has been reported.
