肌鈣蛋白(Tn)是肌肉組織收縮的調(diào)節(jié)蛋白,位于收縮蛋白的細(xì)肌絲上,在肌肉收縮和舒張過程中起著重要的調(diào)節(jié)作用;心肌肌鈣蛋白則僅存在于心肌細(xì)胞中,是由肌鈣蛋白T(cTnT)、肌鈣蛋白I(cTnI)、肌鈣蛋白C(cTnC)三種亞單位組成的絡(luò)合物。
cTnT和cTnI是心肌細(xì)胞特有的抗原,肌鈣蛋白是心肌損傷壞死的標(biāo)志物,對(duì)急性心肌梗死的診斷和危險(xiǎn)分層有重要的臨床意義(診斷敏感性100%,特異性91%,且持續(xù)時(shí)間長(zhǎng))。肌鈣蛋白值升高提示心肌損傷,可見于急性心肌梗死、不穩(wěn)定性心絞痛、肺梗死、心力衰竭休克及其他導(dǎo)致心肌損傷的疾病如胰腺炎、嚴(yán)重糖尿病酮癥酸中毒、結(jié)締組織疾病等,數(shù)值越高,損傷范圍越廣。
