Investigation of elastic features of aorta and color M-mode flow propagation velocity (APV) of descending aorta in the patients with ischemic and non-ischemic dilated cardiomyopathy.
Aortic flow propagation velocity (APV) is a novel echocardiographic parameter used in coronary artery disease. It has also been used for the evaluation of aortic stiffness. In the present study, APV was measured in patients with ischemic and non-ischemic dilated cardiomyopathy (DCM) and was compared with the parameters of aortic stiffness such as aortic distensibility (AD) and aortic strain (AS). ⋯ APV was found to be significantly correlated with AS (r = 0.645, p < 0.001) and AD (r = 0.604, p < 0.001). In ROC analysis, the area under the curve (AUC) value for APV was 0.999 (p = 0.000) for detection of patients ischemic DCM and non-ischemic DCM. APV may be considered to be a novel and a simple echocardiographic marker, for both, distinguishing ischemic from non-ischemic DCM as well as for the presence of dilated cardiomyopathy with or without critical coronary artery disease.
