摘要
目的 评价非体外循环冠状动脉搭桥术 (OPCAB)术后早期心脏功能。方法 OPCAB组 42例 ,体外循环冠脉搭桥术组 6 3例 (对照组 ) ,对比两组血浆心肌酶水平和心电图变化 ,利用Swan Ganz导管分析术中和术后血液动力学变化趋势 ,并评价早期临床效果。结果 两组临床资料无差别。OPCAB组中CK、CK MB、AST、LDH的平均血浆浓度在术后当天、术后 1d、3d和术后 1周均正常 ,而对照组则有升高。OPCAB组心电图阳性变化数目较对照组少见。血液动力学指标显示 ,OPCAB组的心排指数、每搏输出量指数和左室作功指数均较对照组恢复迅速 ,而肺动脉楔压和中心静脉压水平偏低。OPCAB组近期临床效果也较对照组优越。结论 OPCAB组术后早期心脏功能优于体外循环下的冠状动脉搭桥术 ,提示OPCAB手术心肌保护效果好 。
Objective: To assess the early postoperative heart function after off pump coronary artery bypass (OPCAB). Methods: 42 cases in OPCAB (OPCAB group) were compared to 63 cases in coronary artery bypass with cardiopulmonary bypass (Control group). The plasmic level of myocardial enzymes and the change of ECG were observed in both groups. Swan Ganz catheter was used to analyze the hemodynamics in and after operation. And the early postoperative clinical results were assessed. Results: No significance difference was observed in basic clinical data in both groups. The mean level of plasmic CK, CK MB,AST, LDH were normal in OPCAB group in the preoperative day, 1 st postoperative day ,3 rd postoperative day and 1 week after operation. The frequency of the positive change of ECG is less in OPCAB group than that in control group. The hemodynamics data tended to recover soon after operation and the early clinical results were also better in OPCAB group. Conclusions: It seems that OPCAB provide better myocardial protection and compasable clinical resuls.
