[Heart involvement in progressive spinal muscular atrophy. A review of the literature and case histories in childhood].
There are few cardiological studies in progressive spinal muscular atrophy and mainly concern subjects affected by the juvenile form (Kugelberg-Welander disease). The presence of a cardiomyopathy has been reported in these patients but the cardiac involvement is often secondary to the chronic respiratory insufficiency typical of the disease. We performed a retrospective study in our Institute on 43 patients, age range 3 months to 3 years, 37 of which presented type I (Werdnig-Hoffmann disease) and 6 type II (intermediate form) of the disease. No clinical nor instrumental signs of cardiomyopathy were observed. However, ECG revealed signs of right ventricular overload in 37.3% of the patients, probably provoked by pulmonary hypertension due to respiration anomalies. The authors underline the importance of correct respiratory assistance to prevent onset of cardiological alterations.
