Resumen

ACUNA-VALERIO, Jorge et al. Aortic valve calcification prevalence and association with coronary risk factors and atherosclerosis in Mexican population. Arch. Cardiol. Méx. [online]. 2017, vol.87, n.2, pp.108-115. ISSN 1665-1731.  http://dx.doi.org/10.1016/j.acmx.2016.05.013.

Objetive:

The prevalence of aortic valve calcification (AVC), strongly influenced by ethnicity, is unknown in Mexican population. The aim of this study was to investigate the prevalence of AVC and its associations with cardiovascular risk factors and coronary artery calcification (CAC), in Mexican subjects.

Methods:

In 1,267 subjects (53% women) without known coronary heart disease, aged 35 to 75 years, AVC and CAC were assessed by multidetector-computed tomography using the Agatston score. Cardiovascular risk factors were documented in all participants. The associations of AVC with CAC and risk factors were assessed by multivariable logistic regression analyses.

Results:

The overall prevalence of AVC and CAC was 19.89% and 26.5%, respectively. AVC and CAC increased with age and were found more frequently in men (25.5% and 37.1%, respectively) than in women (14.9% and 13.0%, respectively). AVC was observed in only 8.5% of subjects wit-hout CAC, while those with CAC 1-99, 100-399, and > 400 Agatston units had AVC prevalences of 36.8%, 56.8%, and 84.0%, respectively. The multivariable logistic regression analyses, adjusted for age, gender, obesity, physical inactivity, hypertension, dyslipidemia and high insulin levels, showed that the presence of CAC (OR [CI95%]: 3.23 [2.26-4.60]), obesity (1.94 [1.35-2.79]), male gender (1.44 [1.01-2.05]) and age (1.08 [1.03-1.10]), were significant independent predictors of AVC.

Conclusion:

Prevalence of AVC is high and significantly associated with atherosclerotic risk factors and CAC in this Mexican population.
