Background: The intima-media thickness (IMT) has been established as an early predictor of general arteriosclerosis in patients with hypertension. The aims of this study were to establish the relationship between carotid IMT (CIMT) and blood pressure of hypertensive adult patients and to correlate CIMT with age and body mass index (BMI) in hypertensive adult patients.
Patients and Methods: This prospective study was carried out from November 2012 to February 2013 on 200 hypertensive patients aged 21-70 years. The common carotid artery (CCA) was scanned using an ALOKA SSD-3500 ultrasound scanner with Doppler facility and a 7.5MHz linear transducer. Three measurements of the CIMT were obtained at 1cm proximal to the right and left carotid bulb and the mean value of the three measurements was recorded.
Results: There were 200 patients comprising 67 males and 133 females. Their ages ranged 21-70 years, mean of 50.62 ± 10.46 years. The right and left mean CIMT was 0.99 ± 0.13 and 0.99 ± 0.18, respectively; while the overall mean CIMT for both sides was 0.99 mm ± 0.13. The mean BMI for the studied group was 29.09 ± 5.68. The mean systolic and diastolic blood pressure (SBP and DBP) was 157.0 ± 15.5 and 97.6 ± 11.2 mmHg, respectively. There was a significant difference in the mean CIMT value for each SBP and DBP groupings. CIMT correlated positively with age and blood pressure, but had a negative correlation with BMI. Carotid plaques were seen in the CCA wall of 20 patients (10%).
Conclusion: In hypertensives, age and blood pressureare the most important determinants of CIMT. The incidence of carotid plagues in our patients was high; therefore, good control of blood pressure in hypertensives may reduce the incidence of carotid plaques and stroke.
