ABSTRACT

Objective To investigate the clinical characteristics,surgical experience and mid-term outcome of coronary artery bypass graft surgery in patients aged ≤ 40 years.Methods From Jan.,2009 to Dec.,2015,12 patients with median age of (37.9 ± 2.5) years (range 32-40 years,10 males) were diagnosed with coronary artery disease and underwent coronary artery bypass graft surgery at Zhongshan Hospital,Fudan University.The clinical characteristics included five cases with hypertension,three cases with diabetes mellitus,four cases with hyperlipemia,eight cases with smoking history,seven cases with myocardial infarction.Six cases had at least one branch totally occluded.Two cases once underwent percutaneous coronary intervention surgery and implanted with five and three stents respectively.The perioperative data and follow-up results were retrospectively analysed.Results There was no in-hospital death and no death during follow-up period.Surgical techniques included bilateral internal mammary arteries combined with radial artery were operated in six cases,bilateral internal mammary arteries combined with great saphenous vein in two cases,left internal mammary arteries combined with great saphenous vein in four cases,off-pump in nine cases and on-pump in three cases.The mean follow-up time was (47.8 ± 24.3) months.During the follow-up one case suffered with saphenous vein graft restenosis 5 years after the surgery and underwent percutaneous coronary intervention.Other cases were all alive and assessed New York Heart Association's function class Ⅰ-Ⅱ.Conclusions Younger patients usually suffer with severe coronary artery disease when diagnosed because they often have excellent compensative capacity and the pathogenesis is concealed.The mid-term results of coronary artery bypass graft surgery in patients aged ≤40 years are satisfactory.
