The technique " improed coordinated timing of mechanical actiation of papillary muscle insertion sites and the remote decrease of functional mitral regurgitation secondary to left entricular reerse remodeling , " the authors write 作者指出，这一技术提高了乳头肌插入部机械出发和远隔部位二尖瓣重构导致的二尖瓣功能降低性返流之间的协同考虑。
Although cardiac effects of il - 2 have been reported , the mechanisms of action have not been fully elucidated . negative inotropy of il - 2 , partially mediated by no , was observed in hamster papillary muscle . further , clinical research has shown that il - 2 has negative inotropic properties in patients receiving il - 2 therapy 作为在体内分布相当广泛的细胞因子(如il - 2等) ，其对心血管系统的作用尽管已经开始认识，但是对其作用和机制的了解还不够全面和深入，特别是通过何种信号转导途径发挥作用了解不多。
