Abstract:
Objective To investigate the clinical therapeutic methods and their curative effects in recurrent ischemic angina for internal mammary artery resterosis after coronary artery bypass grafting (CABG).Methods We enrolled the patients who had recurrence of ischemic angina for restenosis of internal mammary artery graft after CABG as research subjects in the Affiliated Hospital of Yan'an University from January 2014 to January 2016.The 42 patients were divided into three groups according to the different treatment approaches for recurrence of ischemic angina:Group A (n=22)who received internal mammary artery interventional therapy;Group B (n=12)who received coronary artery bypass grafting treatment;and Group C (n=8)who received left subclavian artery proximal stent treatment.Then we compared the clinical therapeutic effects in the three groups.Results The success rate in Group C was 100%,which was the highest in the three groups,and the post-operative restenosis rate was 0.The hospitalization time was significantly shorter in Group A than in Group B (P＜0.05).However,the two groups did not significantly differ in mortality,success rate or restenosis rate (P＞0.05).Conclusion We should select the appropriate treatment according to the patient's specific situation for recurrent ischemic angina. Endovascular treatment has evident therapeutic effects,rapid postoperative recovery,and lower treatment risk, making it the preferred treatment when possible.
