BACKGROUND: Increasing common carotid artery intimal medial thickening (CCA IMT) is associated with increased cardiovascular risk. The purpose of our investigation was to see if there was any relationship between the different ranges of body mass index with CCA IMT. Body mass index was divided into normal, overweight, obese and morbidly obese.
METHODS: LETTERfile our cardiology consultation letter record and CAROTIDfile ourcarotid duplex imaging (CDI) modules of CARDIOfile, our cardiology database were searched to find patients who had undergone CDI within 90 days of their cardiology consultation. BMI was calculated in the normal manner. Patients were then divided into those with a normal BMI of 18-25kg/M2, those who are overweight with a BMI of 26-30kg/M2, those who are obese with a BMI of 30-40kg/M2 and the morbidly obese with a BMI of >40kg/M2. Common carotid artery (CCA) intimal medial thickness (IMT) was measured manually in the far wall. One way ANOVA testing was used to determine differences between the means and Tukey-Kramer inter-comparisons testing was performed if the ANOVA level of significance was <0.05.
RESULTS: See image below.
CONCLUSION: Obesity is an increasing problem within our society. Obesity is generally felt to be associated with an increased cardiovascular risk. This data would suggest that obesity alone does not appear to be associated with increased carotid atherosclerosis.
