Key result
The author hypothesizes that in hereditary sarcomere myopathies, altered actomyosin kinetics cause sarcomere-level mechanical instabilities and non-uniform force generation between cells, leading to localized stretch and activation of hypertrophic signaling pathways.

May underlie remodeling in sarcomeric HCM; hypothesis-generating and requires validation before clinical consideration.
This hypothesis paper proposes that mechanical instabilities and non-uniformities in sarcomeres may drive the long-term secondary remodeling seen in familial hypertrophic cardiomyopathy.
Alf MÃ¥nsson (2014) studied Hereditary sarcomere myopathies. The author hypothesizes that in hereditary sarcomere myopathies, altered actomyosin kinetics cause sarcomere-level mechanical instabilities and non-uniform force generation between cells, leading to localized stretch and activation of hypertrophic signaling pathways.
