Carotid intima-media thickness in confirmed prehypertensive subjects: predictors and progression.
Arterioscler Thromb Vasc Biol. 2007 Oct; 27(10):2244-9.AT

Abstract

OBJECTIVE

The purpose of this study was to test whether carotid intima-media thickness (IMT) is already increased in normotensive subjects who progress to hypertension (confirmed prehypertensives) independently of known determinants of vessel wall thickness.

METHODS AND RESULTS

Common carotid artery (CCA) far-wall IMT was measured (B-mode ultrasound) in 1536 subjects from the population-based Mexico City Diabetes Study at baseline and 3.5 years later. In the 136 confirmed prehypertensives, CCA-IMT (720 [253] microm, median[interquartile range]) was intermediate between normotensives (615 [140] microm) and hypertensives (725 [215] microm). After multiadjusting for gender, age, BMI, blood pressure, total cholesterol, antihypertensive therapy, and diabetes, converter status was independently associated with a higher CCA-IMT (+93+/-14 microm). At follow-up, CCA-IMT increased by 35 [180] microm. Gender, age, blood pressure, and presence of diabetes, but not the converter status, were significant independent predictors of CCA-IMT progression. In a model adjusting for gender, age, blood pressure (level, status and treatment), diabetes status, total and HDL-cholesterol, the G variant of the 45T/G polymorphism of the adiponectin gene was associated with a hazard ratio of 1.45 (95% CI: 1.04 to 2.01) of a baseline CCA-IMT in the top quintile.

CONCLUSIONS

In confirmed prehypertensives, CCA-IMT is increased independently of blood pressure and known determinants of wall thickness, but short-term CCA-IMT progression is not accelerated.
