Tissue Doppler imaging in assessing elastic properties of aorta in patients with dilated cardiomyopathy

Objective To evaluate elastic properties of the proximal aorta assessed by tissue Doppler imaging(TDI) in patients with dilated cardiomyopathy(DCM).Methods Thirty-three patients with DCM and 30 healthy volunteers were selected.After arterial pressure was measured,all subjects were immediately linked with electrocardiogram(ECG).Internal aortic systolic and diastolic diameters were obtained at 3 cm above the aortic valve with M-mode...
