In particular, we focus on sarcomeric protein isoform transitions in cardiac muscle: a journey to heart failure the effects on polymerization of both actin isoforms, as well as interaction with myosin in the presence of regulatory proteins, as detected by myofibrillar ATPase activity. BBA-Molecular Basis of Disease. Besides cardiomyopathies, heart failure can be caused by other conditions, particularly by coronary artery disease and hypertension which are the leading causes of cardiac death 13.
