Abstract

Objectives: Evaluation of left ventricular function by echocardiography before and after coronary artery bypass graft surgery in patients with type 2 diabetes. Subjects and methods: a cross-sectionnal observation study in 46 patients with type 2 diabetes were included coronary artery bypass graft surgery from 8/2020 to 8/2021 at Hanoi Heart Hospital. Results: Mean age 66±8.73; male/female ratio is 2.83/1; 43.5% of patients smoke; the rate of chest pain was 69.6% and NYHA III - IV accounted for 28.6%. Echocardiographyresult: The number of disturbance areas before and after surgery were 3.52±5.39 and 2.54±4.87. Echocardiography resultin the group with preoperative EF < 50%: Dd before and after surgery were 53.3 ± 7,12mm and 50,3± 6,93mm. Ds before and after surgery were 40,4± 8,44mm and 36,8 ± 8,05mm, Vd before and after surgery were142,2±48,77ml and 124,2 ±38,9ml. Vs before and after surgery were77±42,13ml and 61,1 ±29,47ml, LVMI before and after surgery were135,5 ± 44,61 grams and 117,4 ± 30,17grams, EF before and after surgery were 39,22 ± 8,4% and 45,83 ± 13,39% There was a statistically significant improvement in ultrasound parameters in the group with preoperative EF < 50%: EF increased significantly while cardiac chamber volume, chamber size and left ventricular muscle mass decreased. Particularly in the EF group, the parameters decreased but there was no statistical significance. Conclusion: Coronary bypass surgery significantly improved left ventricular function immediately after surgery in the group with low EF before surgery.
