Case reports:
A 42 years old male was admitted to our hospital in the year of 2019
with a complaint of 19 years history of lower limb muscle weakness and
chest tightness and exertional dyspnea for 3 years. At the age of 23,
his body posture and gait began to change when climbing the stairs,
accompanied by weakness and muscle atrophy of both lower limbs.
Assistance by hands was required during squatting and standing up. These
changes, with a progressive aggravated trend, mainly focused on the
proximal muscles of both lower limbs.
Since the initiation of the disease, he repeatedly sought for medical
help in various hospitals. Typical characteristics of active myogenic
injure was detected by electromyogram (EMG) in 2011. Diagnosis ofDystrophinopathy was confirmed by muscle biopsy on August 2011.
No special treatment was applied to him.
He developed exertional dyspnea with orthopnea at night 3 years ago.
Since then, he was repeatedly hospitalized due to heart failure.
