Data from COSMIC-HF highlight the potential of cardiac myosin activation for the treatment of heart failure patients," said Robert I.
The fundamental assumptions of this model were that the balance of forces is not only parallel but also perpendicular to the long axis of sarcomeres (myofibrils), taking into account the balance of viscoelastic forces originating from the filament lattice and crossbridges (actin-bound myosin heads); the probability of crossbridge formation is dependent on the spacing of two filaments (lattice constant); and lattice constants decrease with increasing sarcomere length (i.
