What We Do: Carotid Intimal Medial Thickness Testing (Arteriovision)

Patients with diabetes die from heart disease or stroke 80% of the time. Unfortunately controlling blood pressure, cholesterol and glucose are often not enough to slow the cardiovascular disease that is almost always present in patients with diabetes.

CIMT technology has recently been acquired by Desert Endocrinology to help us optimally manage your cardiovascular risk. This technology is capable of detecting changes in your blood vessels before you have abnormalities in your ECG, angiogram or carotid Doppler study. Furthermore, it allows us to monitor your progress as we aggressively treat your cardiovascular disease. We can document improvements or progression and make appropriate adjustments before you end up in the Emergency Room with a cardiovascular complication.

Example: “Mr. Fit” – 62-year old man asymptomatic with no medical problems but a family history of heart disease. Right CIMT was excellent, but left CIMT shows significant thickening and a dramatically increased risk for cardiovascular disease. This information helps us to recognize that a very aggressive approach to cardiovascular risk reduction needs to be adopted: aspirin therapy, cholesterol lowering medications, blood pressure lowering medications, increased exercise, diet and weight loss. Follow-up measurements will be repeated to show his progress in 6–12 months.

Figure 1: Your CIMT Percentile

How you compare to others of similar age and gender

Significance: Compared with a population of healthy indivduals without symptoms of cardiovascular disease, your CIMT value falls into the 26th percentile. This means that 26% of indivduals of the same gender and similar age, have a CIMT value less than yours. In the future, guidelines may specify that a CIMT value greater than or equal to the 75th percentile could elevate a person with multiple risk factors to a higher risk category2.

Figure 2: Your Current Age vs. the Age of Individuals with Your CIMT Value

Significance: With this graph, you can compare your chronological age with the CIMT value of others of the same gender by age group. Compared with a population of healthy indivduals without symptoms of cardiovascular disease, it is estimated from your current CIMT value that your vessel is as thick as someone who is about 45–49 years old (based on a comparison of our CIMT value with their average CIMT value)5.

This ultrasound image shows the region of the carotid artery far wall that was used to determine the CIMT value. The single, horizontal red line represents the 1 cm ruler under which the CIMT was computed.

This means that 95% of indivduals of the same gender and similar age, have a CIMT value less than yours. In the future, guidelines may specify that a CIMT value greater than or equal to the 75th percentile could elevate a person with multiple risk factors to a higher risk category2.
