RESUMO
It has been reported that an increase in carotid artery intima-media thickness (IMT), a sign of early atherosclerosis, has a predictive value for future cardiovascular (CV) events. There are limited data about IMT measurements in renal transplant patients who display a high rate of CV mortality. In this study carotid artery IMT was measured by high resolution B-mode ultrasonography in 102 randomly selected RT patients to assess the relationship between IMT and CV disease and risk factors. A positive correlation was found between IMT and age, triglyceride level, and hematocrit. IMT was significantly higher among patients who were diabetic (0.68 +/- 0.27 vs 0.50 +/- 0.2) or had CV disease (0.88 +/- 0.28 vs 0.53 +/- 0.21). An increased IMT was associated with a longer duration of ESRD, higher lipid level, lower serum albumin, and presence of previous CMV disease. CV disease was more frequent among patients with increased IMT. Considering its relation to CV risk factors, it is concluded that the measurement of carotid artery IMT is an easy, reliable and non-invasive method to be used to assess atherosclerotic disease in renal transplant patients.
