Objectives: To assess the carotid intima media thickness (IMT) with the help of high resolution ultra sonography and to compare the intima Media thickness of hypertensive patients with that of normotensives. Materials and methods: Two hundred and sixty patients of hypertension were studied over a period of three years and compared with seventy normotensive patients. Carotid Doppler was performed on both sides, independently by two different observers with inter observer variation being insignificant. We used WIPRO-GE Logic 400 MD scanner with 7.5 MHZ linear array superficial probe for Ultrasonography with the patient in supine position and elevation of chest by a pillow. Patient's head turned to the opposite side of examination. About 0.5 to 1.0 cm proximal to the carotid bulb, the site was chosen, intima media thickness assessed. Colour flow mapping was done and velocity and vessel size were assessed. Estimation of lipid profile was done. These values of hypertensive patients were compared with that of normotensives. Results: Normal carotid Intima media thickness is 0.77mm and 0.75mm for the Right and Left sides respectively. Intima media thickness is increased in hypertensive subjects significantly when compared with normotensives. HDL Cholesterol is significantly low and Triglycerides level is increased in hypertensive patients. Conclusion: Our study has revealed that assessment of intima media thickness of carotids as assessed by Ultrasonographic study is significantly increased in all hypertensive patients when compared with normotensives.
