Abstract :

It is well recognized that cardio– vascular risk factors lead to histological and functional changes in aorta, and aortic stiffness is the best predictor of cardiovascular morbidity and mortality. Therefore, this study was designed to determine the relation of a less evaluated echocardiographic parameter of aortic stiffness, aortic propagation velocity (APV) with the presence and severity of CAD. This is cross–sectional comparative study done in Department of cardiology, S.C.B. Medical College & Hospital, Cuttack , who underwent conventional coronary angiogram (CAG) between january 2018 to june 2019. Coronary artery disease is considered significant if >50% diameter stenosis is present in any epicardial coronary artery and insignificant if otherwise. Patients were divided into two sub–groups based on angiographic finding, patients with CAD (50patients, 50%) and non–CAD (50 patients,50%)and Transthoracic echocardiography was performed using the conventional 2D and color M–Mode imaging. Aortic propagation velocity was measured. The presence and Severity of CAD and their relation with aortic stiffness was assessed. Among 100 patients who underwent CAG we found 50% had significant CAD, 50% had insignificant CAD , APV (69.10�3.138 Vs 45.94�4.24 P < 0.0001) Aortic propagation velocity was significantly decreased in CAD group compared with non–CAD group. In the present study it was observed that APV was significantly lower (39.73 � 1.348 cm/s) in the triple vessel disease patient than double &single vessel disease APV (a less evaluated echocardiographic index) showed significant inverse correlation with presence and severity of CAD.
