摘要 目的 观察冠脉支架置入术后微小心肌损伤的发生率及其对左室射血分数的影响。方法 对 46例行冠脉内支架置入术 (支架组 )及2 2例行冠脉造影术 (造影组 )的患者术前、术后血液心肌钙蛋白 T(CTn T)及肌酸激酶 MB同工酶 (CK- MB)水平进行测定 ;支架组于术前及术后 4 w行核素左心室射血分数 (LVEF)测定。结果 支架组及造影组术后 CTn T增高的发生率分别为 2 1 .7% (1 0 / 4 6)及 0 % (0 / 2 2 ) ,差异有显著性 (P<0 .0 1 )。行支架置入术的患者中 ,CTn T(+)组术前、术后 LVEF分别为 (56.8± 9.9) %和 (58.8± 1 0 .2 ) % (P>0 .0 5) ;CTn T(- )组术前、术后 L VEF分别为 (58.1± 1 2 .1 ) %和 (68.7± 1 1 .6) % (P<0 .0 5)。同期两组比较 ,术后 CTn T阴性组 LVEF较 CTn T阳性组明显增高 (P<0 .0 5) ,术前两组LVEF无显著差别。结论 成功施行冠脉支架置入术后 ,部分患者出现微小心肌损伤 ,这影响着病人近期心功能的恢复。
