心肌缺血會降低心肌細胞產能及有氧代謝功能

，在心髒活動時不能給予充足的能量供給，從而引起心肌缺氧

、胸悶
、心髒功能減弱等問題。盡 muqianlinchuangshangdezaiguanzhushouduanzaiyidingchengdushangkeyihuanjiexinjiquexuesunshang，danyijingsunshangdexinjixiufukunnanjiquexuezaiguanzhuzaochengdexindexinjisunshanghuidaozhizaiguanzhuzhiliaodebufenbingrenyiranchanshengxinlishuaijiehezuoxinshizhonggou。yincizaijinxingzaiguanzhuzhiliaozhiqiancaiquxinjibaohuyaowuzhiliaokenenghuichanshengxietongdexiaoguo。niuhuangsuannenggoujianhuanxinjiquexuesunshangzailinchuangzhongyoufeichangzhongyaodeyiyi。

       牛磺酸具有抗細胞凋亡、調節內質網應激反應
、促線粒體蛋白質合成、維持滲透平衡從而達到保護細胞膜等功能，牛磺酸在哺乳動物心髒組織內的含量比較高。實驗研究發現

，牛磺酸具有抑製心肌細胞凋亡、抑製內質網應激和調節細胞內滲透壓、抗高血壓和抗動脈粥樣硬化與保護心肌細胞、抗心力衰竭等作用。
