Based on the research conducted by Kaplan, it was found that a person with higher IMT group was inclined to have a risk of being affected by diabetes, hypertension and cardiovascular disease. A high mortality rate occurred in IMT > 25 kg/m2 and > 30 kg/m2 (Kaplan et al., 2014).

The main measure used in vascular ultrasound is the Intima-Media thickness (IMT), defined as the distance between the far wall lumen-intima and the far-wall media adventitia. The IMT is best visualized in longitudinal sections of the carotid (Figure 7.1).

Participants were tested at different locations, and whilst the same ultrasound machine was used different blood pressure monitors and spirometers were used which may have resulted in some variation between groups. Vascular function was only assessed using FMD, future research would benefit from including additional risk factors for CVD including analysis of cholesterol (high and low-density lipoproteins), triglycerides, glucose, and high-sensitivity C-reactive protein to provide a more comprehensive profile of cardiovascular health. Given the indications of adapted vascular structure it may also be of interest to assess intima-media thickness (IMT) in addition to FMD to quantify and track the atherosclerotic process. Furthermore, both the overall group and sub-group consisted of predominately male participants and were not sufficiently powered to explore any potential sex differences. Finally, the researcher performing all FMDs also conducted the analysis and was therefore not blinded for the analysis.

Carotid ultrasound was performed using the Toshiba Medical portable ultrasound equipment Viamo® (Tokyo, Japan) using a 5–11 MHz linear transducer. At least three intima-media thickness (IMT) images of the common carotid artery were obtained bilaterally (right and left) and the image with the best quality (quality index >0.50) for each side was used. Carotid IMT measurements were analysed using the IMT MATH® software (version 3.1, METRIS Co., Argenteuil, France), which measures with an accuracy of <0.007 mm. In addition, the software used performs 100–150 automated measures over a length of 10.0 mm from the opposite wall, giving an individual accuracy of <0.01 mm. The mean (in mm) of the left and right IMT was used in the analyses (Naqvi & Lee, 2014).

Cardiovascular diseases are the leading cause of morbidity and death rate in the Western countries. Atherosclerosis (arterial thickening) is a common cause of cardiovascular diseases. Intima media thickness of common carotid artery is a widely used indicator of atherosclerosis disease. Classically, IMT is a double-line pattern visualised by echo-tomography on both the walls (near and far) of CCA in a longitudinal image referred to Figure 1. With increase in age, the IMT thickens in a consistent course. The process of IMT thickening is accelerated in the presence of atherosclerosis. IMT is defined as the distance between lumen-intima and media-adventitia interfaces (Sun et al. 2002; Touboul et al. 2007; Meiburger et al. 2011; Pu et al. 2012).
