Perfil de riesgo cardiovascular en adultos jóvenes asintomáticos con grosor íntima media carotídeo elevado / Cardiovascular risk factors among young subjects with high carotid intima media thickness

ABSTRACT

Background: Cardiovascular risk factor (RF) assessment is essential to prevent and predict cardiovascular disease. The presence of RF at early ages, are determinant for the presence of atherosclerosis later in life. Aim: To determine the RF profile of young subjects with high carotid intima media thickness (CIMT). Material and Methods: We studied 689 subjects (50 percent women, mean age 36±6 years) from Santiago, Chile. We determined body mass index (BMI), waist circumference, blood pressure, fasting serum lipids, blood glucose and C-reactive protein. CIMT was assessed by ultrasound using an automatic border recognition software. Results: Body mass index, waist circumference, blood pressure and serum lipids were significantly higher among subjects located in the higher CIMT quartile. Also, subjects in the higher quartile of CIMT had a higher prevalence of three or more RF compared with the lower quartile (p = 0.01). Finally, individuals with three or more RF showed three times more risk of being in the higher CIMT quartile, than subjects with no RF (odds ratio = 3.1, p < 0.01). Conclusions: There is a negative influence of cardiovascular RF on CIMT among young subjects.
