目的 :探讨左室功能减退患者冠状动脉旁路移植术 (CABG)的治疗结果。方法 :回顾性分析 2 0 0 0年12月～ 2 0 0 3年 4月因心肌梗死或长期慢性心肌缺血造成左室功能减退的 6 7例冠心病 (CHD)患者CABG的相关资料。结果 :6 7例中 ,6 1例联合应用左乳内动脉与前降支吻合 ,人均旁路移植 1～ 5 ( 3.4± 0 .3)支 ,无手术死亡。术后 6 7例随访 2～ 2 6个月 ,死亡 3例。左室射血分数由术前 ( 30 .9± 9.2 ) %提高至 ( 4 1.5± 6 .7) % ;左室舒张末内径由术前 ( 6 3.7± 7.9)mm降至 ( 5 6 .8± 3.4 )mm(P >0 .0 5 ) ;心绞痛发作明显减少 ,活动耐力均提高。结论 :左室功能减退的CHD患者 ,CABG手术成功率和近期效果满意
Objective: To investigate the therapeutic effect of coronary artery bypass grafting (CABG) in patients with left ventricular dysfunction. Methods: The data of CABG in 67 CHD patients with left ventricular dysfunction caused by myocardial infarction or long-term chronic myocardial ischemia from December 2000 to April 2003 were retrospectively analyzed. Results: In 67 cases, 61 cases were combined with the anastomosis of the left internal mammary artery and the anterior descending artery. Peritoneal grafts were transplanted from 1 to 5 (3.4 ± 0.3) branches per patient without any surgical death. Sixty-seven patients were followed up for 2 ~ 26 months and 3 died. The left ventricular ejection fraction increased from (30.9 ± 9.2)% to (4 1.5 ± 6.7)% preoperatively, while the left ventricular end-diastolic diameter decreased from (6 3.7 ± 7.9) mm to (56.8% ± 3.4) mm (P> 0.05). The incidence of angina decreased significantly and the activity endurance increased. Conclusion: The success rate of CABG surgery and the recent results are satisfactory in CHD patients with left ventricular dysfunction
