Description

<p>Background:Although there have been several reports on the risk factors associated with intima-media thickness (IMT), many questions remain. The purpose of this study was to investigate the association between IMT and cardiovascular risk factors in a Japanese general population.</p><p>Methods and Results:The study group consisted of 1,583 male subjects undergoing routine health checkups. IMT of the common carotid artery was measured by high-resolution ultrasonography. Brachial-ankle pulse wave velocity (baPWV) was measured using an automated device. Univariate analysis demonstrated that carotid IMT significantly associated with age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), baPWV, fasting glucose, low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and high-density lipoprotein cholesterol (HDL-C). Multiple logistic regression analysis for carotid atherosclerosis (carotid IMT ≥1.0 mm) was performed using obesity (BMI ≥25.0 kg/m2), high BP (SBP ≥130 mmHg or DBP ≥85 mmHg), dyslipidemia (LDL-C ≥140 mg/dL, TG ≥150 mg/dL, or HDL-C <40 mg/dL), impaired fasting glucose (IFG) (fasting glucose ≥110 g/dL), and high baPWV (≥1,400 cm/s). Carotid atherosclerosis was significantly associated with only high baPWV (OR: 2.22, 95% CI: 1.24–4.17, P<0.01).</p><p>Conclusions:High baPWV was a stronger predictor of early carotid atherosclerosis than high BP, dyslipidemia, or IFG in a Japanese general male population.</p>
