Abstract:
Objective: To assess the regional systolic and diastolic function of left ventricle by pulsed wave Doppler tissue imaging ( PW-DTI) in patients with coronary artery disease ( CAD ) . Methods : Seventy-seven cases of coronary angiography were adopted for study and grouped in terms of severity of coronary arterial lesion. Peak systolic, peak early diastolic, and peak late diastolic motion velocities (Sm, Em and Am, respectively) were recorded at 6 different sites on the basal and medial segments corresponding to the anteroseptal, posteroseptal, lateral, anterior, inferior, and posterior walls of the left ventricle with PW-DTI. Results: Am in segments corresponding to normal coronary arteries (group A) was lower than in segments corresponding to slightly stenosed coronaries (group B). There was no significant difference in Sm and Em between group A and group B. Compared with group A, Sm, Em and Am were significantly decreased in segments corresponding to severely stenosed coronary arteries ( group D). Conclusion : PW-DTI could be used to evaluate quantitatively and accurately the regional mvocardial function of left ventricle in patients with CAD.
