Applications CK 1827452 is a promising new drug in systolic heart failure. It accelerates the transition of myosin into the force-generating state without affecting cardiac myocyte calcium homeostasis. CK 1827452 increases cardiac function by increasing the duration of ejection without changing the rates of contraction. References Meijs, M. et al.: Eur. J. Heart. Fail., 14, 232 (2012); Malik, F. et al.: J. Mol. Cell. Card., 51, 454 (2011)
