Abstract

From 2/2010 to 12/2014, there were 93 patients underwent CABG surgery. The mean age was 65.34 ± 7.65 years old (ranged from 44 to 83 years), female accounted to 22.66%. The classic CABG surgery with extra-corporeal circulation, aortic cross clamp to perform cardioplegia, myocardial protection using warm-blood solution. On follow-up visit, evaluation of the mid-term results after surgery based on clinical symptoms, trans-thoracic echocardiography, bypass graft assessment by selective percutaneous coronary angiography or multi-slice computed tomography angiography. 87/93 patients survived until discharge. Mean follow-up duration was 52.13 ± 14.79 months (ranged from 25 – 79 months), loss of follow-up: 2 patients. There were 9 deaths, accounted to 10.58%, during follow-up (5 was due to cardiovascular diseases), 76 patients survived. Clinical: 13 patients had recurrent angina, there was no cases with heart failure NYHA class III, IV. Comparison between echocardiography at discharge and on follow-up visit: no significant differences in EF, the number of patients had wall motion abnormalities was higher during follow-up compare to that at discharge. 225 bypass grafts were assessed: 141 were patent (62.68%); 84 were stenosed (37,33%). Bypass graft to coronary artery whose pre-operative stenosis was ≥ 95% had lower rate of stenosis (p = 0.009). Left internal mammary artery graft had the highest rate of patency, there was no differences between radial artery graft and saphenous vein graft (p < 0.05). Patients undergoing coronary artery bypass graft surgery experienced clinical improvement. The most common cardiovascular complications during postoperative follow-up were: death, graft stenosis requiring intervention. Left internal mammary artery graft has the highest quality.
