The cardio-ankle vascular index (CAVI) assesses arterial stiffness. We aimed to describe the distribution of CAVI in a Mediterranean population, to determine the proportion of CAVI ≥ 9 by sex and coronary risk level, and to assess the association of CAVI with classic cardiovascular risk factors and lifestyle patterns.
This cross-sectional study was based on the population of Girona province. The CAVI was measured using the VaSera VS-1500.
Of 2613 individuals included in this study, the prevalence of CAVI ≥ 9 was 46.8% in men and 36.0% in women and significantly increased with coronary risk: from 21.1% and 24.8%, respectively to 76.7%, in the low-risk group, and 61.9% in the high-risk group. The CAVI increased with age in both sexes, being higher in men across all age groups. In men, CAVI ≥ 9 was associated with hypertension (OR, 2.70; 95%CI, 1.90-3.87) and diabetes (OR, 2.38; 95%CI, 1.52-3.78), body mass index (BMI) ≤ 25 to < 30 (OR, 0.44; 95%CI, 0.27-0.72) and BMI ≥ 30 (OR, 0.28; 95%CI, 0.14-0.58), and physical activity (OR, 0.66; 95%CI, 0.47-0.92). In women, CAVI ≥ 9 was associated with hypertension (OR, 2.22; 95%CI, 1.59-3.09), hypercholesterolemia (OR, 1.40; 95%CI, 1.01-1.94), and BMI ≥ 30 (OR, 0.38; 95%CI, 0.20-0.71).
The CAVI increases with age and is higher in men than in women. This index is associated with classic risk factors and coronary risk. It could be a good predictive biomarker, but further follow-up studies are required to assess its added value to cardiovascular risk stratification.
心踝血管指数（CAVI）用于评估动脉僵硬度。我们旨在描述地中海人群中CAVI的分布情况，确定按性别和冠心病风险水平划分的CAVI≥9的比例，并评估CAVI与经典心血管危险因素及生活方式模式之间的关联。
这项横断面研究以赫罗纳省的人群为基础。使用VaSera VS - 1500测量CAVI。
在本研究纳入的2613名个体中，CAVI≥9的患病率在男性中为46.8%，在女性中为36.0%，且随冠心病风险显著增加：在低风险组中，分别从21.1%和24.8%增至76.7%，在高风险组中为61.9%。CAVI在两性中均随年龄增长而升高，在所有年龄组中男性的CAVI更高。在男性中，CAVI≥9与高血压（比值比[OR]，2.70；95%置信区间[CI]，1.90 - 3.87）、糖尿病（OR，2.38；95%CI，1.52 - 3.78）、体重指数（BMI）≤25至<30（OR，0.44；95%CI，0.27 - 0.72）以及BMI≥30（OR，0.28；95%CI，0.14 - 0.58）和身体活动（OR，0.66；95%CI，0.47 - 0.92）相关。在女性中，CAVI≥9与高血压（OR，2.22；95%CI，1.59 - 3.09）、高胆固醇血症（OR，1.40；95%CI，1.01 - 1.94）以及BMI≥30（OR，0.38；95%CI，0.20 - 0.71）相关。
CAVI随年龄增长而升高，男性高于女性。该指数与经典危险因素及冠心病风险相关。它可能是一个良好的预测生物标志物，但需要进一步的随访研究来评估其对心血管风险分层的附加价值。
