Role of Echocardiographic Aortic Propagation Velocity in Predicting Obstructive Coronary Artery Disease – A Prospective Observational Study

Abstract

Objectives: The aim of this study was to assess the relationship between APV and CAD and to compare AS and AD in patients with and without CAD. Material and Methods: A total of 100 subjects presenting to Government General Hospital, Guntur, with chest pain and undergoing coronary angiogram were selected for the study. Patients were divided into two groups, the study group comprises patients with >50% stenosis in at least one of the coronary artery on coronary angiogram, and control group comprises patients with normal coronaries on angiography. Two-dimensional echocardiography (Philips Affinity 70) was performed with the recording of data. AS and AD were calculated and APV was determined. Result: In the present study, it was observed that there was a statistically significant increased incidence of deranged lipid profile, diabetes, hypertension, alcohol consumption, and a positive family history of CAD in the study group. Mean APV, mean AD, and mean AS was significantly low in the study group as compared to the control group (P < 0.001). Conclusion: APV, AS, and AD can be used as surrogate marker to predict the presence of significant CAD and, hence, can be safely recommended as a simple, economical, and non-invasive means to screen CAD.
