Abstract:
Background : Elastic properties of the aorta affect the left ventricular function and epicardial arteries blood flow. Thats why several parameters are used to assess those properties in order to predict the likelihood of atherosclerotic coronary artery disease. Those parameters include aortic strain, aortic distensibility and early diastolic velocity of the anterior aortic wall.Objectives : Testing the value of aortic propagation velocity as a parameter of aortic stiffness in predicting coronary artery disease. The strength of this parameter in predicting the number of affected coronary arteries is also assessed.st of August 2015 to the 1 st Study population and methodology : From the 1 of July 2016, and after applying the inclusion and exclusion criteria, 120 patients were included in this comparative multi - center study. They were assessed for demographic criteria and risk factor profiles. Trans thoracic echocardiographic examination was done, all the needed measurements were obtained as well as measuring the carotid intima media thickness by Doppler, then the results of their coronary angiography were revised, 60 patients were included in the coronary artery disease group and another 60 in the non - coronary artery disease group.Results : Aortic propagation velocity was found to be related to the aortic distensibility, strain, early diastolic anterior aortic wall velocity and the overall carotid intima media thickness to a statistically significant level (r=+0.481, p<0.001; r=+0.548, p<0.001; r=+0.595, p<0.001; r= - 0.361, p<o.oo1 respectively). It was found that aortic propagation velocity predicts coronary artery disease (p<0.001) and correlates with the number of affected coronary arteries (r= - 0.711, p<0.001).Conclusion : Aortic propagation velocity is an easily applied echocardiographic parameter of aortic stiffness that can predict coronary artery disease caused by vascular atherosclerosis in a non - invasive way. It also correlates with the number of the affected coronary arteries.
