[摘要] 目的 探讨患者术前及术后的cTnI水平、cTnI阳性发生率。方法 整群收集2014年1月—12月在该院心内科行抗缓慢型心律失常人工心脏起搏器、心功能(NYHA)分级Ⅱ级以下的患者54例，用酶联免疫试剂盒分别测量患者术前、术后1 d、术后1周的cTnI水平及cTnI阳性发生率。 结果 cTnI阳性发生率为38.89%，术前、术后1 d、术后1周的cTnI水平分别为(4.67±0.60)ng/mL、(6.63±0.80)ng/mL、(4.67±0.60)ng/mL，术前与术后1 d相比，差异有统计学意义(P0.05)。 结论 抗缓慢型心律失常人工心脏起搏器对心肌造成微小损害，在术后1周时cTnI水平可恢复在正常范围内。

 [Abstract] Objective To investigate the preoperative and postoperative level of cTnI and cTnI positive rate. Methods 54 cases with below grade Ⅱ cardiac function classification by NYHA underwent the implantation of anti-bradyarrhythmia artificial cardiac pacemaker in Department of Cardiology in our hospital from January 2014 to December 2014 were selected. ELISA kits were used to measure the level of cTnI before surgery ...... 第 1 2 页 下一页
