The cardiomyopathy in Friedreich's ataxia — New biomarker for staging cardiac involvement

Abstract: A comprehensive cardiac assessment will unravel established CM in almost all patients with FA with electrocardiographic abnormalities as earliest signs. Advanced stages can be characterized by elevated hsTNT and replacement fibrosis leading to recession of hypertrophy, reduction of global myocardial function, and electrical instability.

“…Так, при развитии первичной ГКМП увеличивается не только длина и толщина кардиомиоцитов, но меняется и их пространственная ориентация, т. е. кардиомиоциты межжелудочковой перегородки рас-полагаются поперечно, а не продольно. Подобных морфологических признаков при аутопсии не выяв-ляется у пациентов с кардиомиопатией при АФ, что, по всей видимости, и обусловливает низкую частоту развития желудочковых аритмий [8][9][10][11][12][13].…”

“…Neurological symptoms precede cardiac in the majority, although 90% develop cardiac involvement (concentric hypertrophy) under the age of 18 years [39] (Figure 3) . ECG abnormalities are seen in most patients (90%) which include repolarisation abnormalities, abnormal QRS axis and left ventricular hypertrophy [40] There are conflicting reports regarding the association between disease severity and the length of Frataxin repeat or neurological and cardiac manifestations [41,42]. The natural history of cardiac involvement is progression to a dilated phenotype with decline in ejection fraction over time [43].…”
