Provided are a composition for preventing or treating heart failure and a method for screening an agent for treating heart failure. The present disclosure demonstrates for the first time that administration of PKCζ inhibitor provides inotropic effect by increasing myocardial contractility. Thus, the present disclosure will contribute greatly to the prevention or treatment of heart failure. Also, since the present disclosure is based on the change in calcium sensitivity in cardiac myocytes unlike the existing inotropic agents, it can enhance the myocardial contractility without increasing oxygen demand or the risk of arrhythmia.
提供了一种预防或治疗心力衰竭的组合物以及一种筛选治疗心力衰竭药物的方法。本公开首次证明了PKCζ抑制剂的给药通过增加心肌收缩力提供正性肌力作用。因此,本公开将极大地有助于预防或治疗心力衰竭。此外,由于本公开基于心肌细胞中钙敏感性的变化,不同于现有的正性肌力药物,它可以增强心肌收缩力而不增加氧需求或心律失常的风险。
