目的 探讨介入治疗对非ST段抬高的急性冠脉综合征(NSTE-ACS)患者心功能的影响。方法 选取2013年2月-2015年 2月期间我院收治的140例非ST段抬高的急性冠脉综合征患者作为观察对象，所有患者采用介入治疗，观察介入术 前及术后非ST段抬高的急性冠脉综合征各项指标和患者心功能的改变情况。结果 介入术后通过对肌酸激酶同工酶 (CK-MB)、心肌钙蛋白(cTn)、左心室舒张末径(LVDD)和左心室射血分数(LEVF)和心功能分级评定结果显示，术后指 标相对于术前有明显改善，增强了心肌灌注能力。同时术后心功能二级以上的患者明显降低。结论 介入治疗可以 改善心室泵血功能，有助于NSTE-ACS患者心功能改善。

Objective To investigate interventional treatment influence on cardiac function in patients with non-ST segment elevation acute coronary syndrome(NSTE-ACS). Methods 140 cases with NSTE-ACS were selected as the object from February 2013 to February 2015 in our hospital, all patients treated with interventional therapy, the NSTE-ACS comprehensive indexes and the change of cardiac function were observe before and after the intervention operation. Results After intervention therapy, postoperative index compared was improved significantly with the ability of cardiac muscle perfusion enhanced based on the creatine kinase (CK-MB), cardiac troponin (cTn), left ventricular enddiastolic diameter (LVDD) and left ventricular ejection fraction (LEVF) and heart function classification results. At the same time, the amount of patient with postoperative heart function more than Grade-2 was decreased significantly. Conclusion Interventional therapy can improve ventricular pump function, which is helpful for the improvement of heart function in patients with NSTE-ACS.
