Observational Study on Cardiac Biomarkers Testing in Patients with Muscular Dystrophy Cardiomyopathy

The objective of this study is to evaluate acute changes of cardiac troponin (and other cardiac biomarkers) and mid-term biovariability in patients with cardiomyopathy associated with chronic skeletal muscle disease. The specific aims of the study are: Firstly, to evaluate the feasibility of the ESC 0/1 hour protocol for rule-in and rule-out of a non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Secondly, a) to determine reference change values (RCV) to characterize physiological biovariability, b) to differentiate acute from chronic high-sensitivity cardiac troponin T (hs-cTnT) elevations.
