Abstract
Purposes: Determination of elastic indices of the aorta in hypertensive patients by M-mode echocardiography and investigation of the correlation between aortic elastic indices with blood pressure and left ventricular morphology.
Methods: A cross - sectional descriptive study was conducted on 70 hypertensive patients with the hypertension diagnostic criteria 2021 from the Vietnam Hypertension Society/Vietnam Cardiology Association, who came to be examined and treated at the cardiovascular center, Hue Central Hospital from April 2022 to August 2022 and 97 subjects were in the control group. Assess aortic elasticity through 3 indices: Aortic tension (%) = (AODs - AODd) x 100/ AODs, aortic stiffness index (%) = ln (SBP/ DBP)/ [(AODs - AODd )/ AODd], aortic distension (cm2.dyn-1.10-3) = 2 x tension x (SBP - DBP).
Results: The arterial stiffness index of the aorta increased, on the contrary, the tension and dilation of the aorta decreased in the disease group compared to the control group (p < 0.05). Aortic stiffness was positively correlated strongly with BP values. However, Aortic tension and dilation were negatively correlated with three blood pressure values. The indexes of LVMI, RWT, IVSd, LVPWd had a positive correlation with aortic stiffness (p < 0.05) and had a negative correlation with tension and dilation of aorta (p < 0.05).
Conclusion: Simple echocardiographic techniques such as M-mode can assess aortic elasticity. Thereby contributing to the early detection of aortic diseases in hypertensive patients.
