Abstract

Objective: The aim of this study is to investigate the influences of body composition on carotid artery structure and function in adult humans. Methods: 50 volunteers were considered for carotid ultrasound scanning using Doppler ultrasound machine to measure their lumen diameter (LD), intima-media thickness (IMT), peak systolic velocity (PSV) and End Diastolic velocity (EDV), pulsatility index (PI) and resistivity index (RI) of their right and left common carotid artery (CCA). Body composition was classified using body mass index (BMI) and waist-to-height ratio (WHtR) values calculated from mass, height and waist measurements. Results: The right peak systolic velocity (RPSV) has a negative correlation with WHtR (p<0.05), right intima-media thickness (RIMT) (p<0.01), right lumen diameter (RLD) (P<0.05) and age (p<0.05) but positively correlated with Height (p<0.01). Right end diastolic velocity (REDV) is strongly correlated negatively with RLD (p<0.01), left lumen diameter (LLD) (p<0.05) while it is positively correlated with age (p<0.05). Left peak systolic velocity (LPSV) has a positive correlation with height while the left end diastolic velocity (LEDV) is positively correlated with WHtR. Conclusion: Measurements such as height, WHtR, IMT, LD and blood flow velocity (BFV) are significantly linked with cardiovascular diseases.
