Resumen

POSADAS-ROMERO, Carlos et al. Prevalence and extent of coronary artery calcification in an asymptomatic cardiovascular Mexican population: Genetics of Atherosclerotic Disease study. Arch. Cardiol. Méx. [online]. 2017, vol.87, n.4, pp.292-301. ISSN 1665-1731.  http://dx.doi.org/10.1016/j.acmx.2016.12.004.

Objective:

The prevalence of coronary artery calcification (CAC), a specific marker of atherosclerosis, is unknown in Mexico. Our aim was to investigate the prevalence and quantity of CAC and their association with cardiovascular risk factors in a Mexican population.

Methods:

CAC was measured by multidetector computed tomography in asymptomatic subjects who participated in the Genetics of Atherosclerotic Disease study. Cardiovascular risk factors and medication were recorded.

Results:

The sample included 1,423 individuals (49.5% men), aged 53.7 ± 8.4 years. Those with CAC showed a higher prevalence of dyslipidaemia, diabetes, hypertension, and other risk factors. The prevalence of CAC > 0 Agatston units was significantly higher among men (40%) than among women (13%). Mean values of CAC score increased consistently with increasing age and were higher in men than women in each age group. Age and high low density lipoprotein cholesterol were independently associated with prevalence of CAC > 0 in men and women, while increasing systolic blood pressure in women and age in both genders showed an independent association with CAC extension.

Conclusions:

In the Mexican population the prevalence and extent of CAC were much higher in men than in women, and strongly increased with age. Independent predictors of CAC prevalence were age and low density lipoprotein cholesterol (LDL-C).
