Aim: To evaluate left ventricle (LV) diastolic function dynamics in patients after acute myocardial infarction (AMI) after combined operation of coronary artery bypass graft with LV aneurismectomy (CABG + AE) according to the results of tissue Doppler imaging (TDI).

Methods: Forty patients after AMI underwent Doppler echocardiography (EchoCG) with TDI and M-mode colour-flow imaging before and in 3 and 12 months after CABG + AE. Mitral annulus (MA) TDI with velocity indices was performed in 4 segments of LV.

Results: Conventional transmitral diastolic Doppler indices before and after CABG + AE remained unchanged. TDI showed significant improvement of LV systolic (systolic movement velocity S: 6.1±0.8, 7.4±1.2 and 6.9±1.3 cm/sec. before and in 3 and 12 months after the operation, respectively, p<0.01) and diastolic function after the operation (MA early diastolic movement velocity (e’): 7.3 ± 2.1, 8.4 ± 1.5 and 8.9 ± 1.8 cm/s.; ratio of transmitral early-flow velocity (E) to MA early-diastolic movement velocity (E/e’): 18.4 ± 2.2, 12.3 ± 1.8 and 11.5 ± 2.3; ratio of E diastolic flow propagation velocity (Vp) 3.1 ± 0.45, 2.2 ± 0.38 and 1.8 ± 0.16 before and in 3 and 12 months after the operation, respectively, p<0.01).

Conclusions: Results of the study demonstrate significant improvement of LV diastolic function in the patient after CABG + AE according to TDI, regardless of transmitral flow pattern. TDI is more sensitive and preload independent method of LV myocardial function evaluation.
