Therefore, we studied the performance of hs‐cTn T (hs‐cTnT; Roche Diagnostics) and hs‐cTn I (hs‐cTnI; Siemens Atellica IM) to identify cardiac involvement in a cohort of stable patients with confirmed muscle dystrophies who were referred from the neurology department for diagnosis of cardiac involvement and/or monitoring of cardiac disease. Here, TNNI3 is linked to heart disorder.
