摘要: Background and Purpose Calcium handling is known to be deranged in heart failure. Interventions aimed at improving cell Ca2+ cycling may represent a promising approach failure therapy. Istaroxime new luso-inotropic compound that stimulates cardiac contractility relaxation healthy failing animal models patients with acute (AHF) syndrome. Na-K ATPase inhibitor the unique property of increasing sarcoplasmic reticulum (SR) SERCA2a activity as shown microsomes from humans guinea pigs. The present study addressed molecular mechanism by which istaroxime increases activity.
