Aims and objectives


Coronary Artery Disease is a main cause of mortality around the globe.

According to the World Health Organization (WHO), cardiovascular disease is a group of conditions that affect the heart and blood vessels.


Approximately 17.5 million people died because of cardiovascular disease in the year 2012, which represent 30% of the total. 7.4 million of them were caused by coronary disease and 6.7 million were caused by acute stroke, moreover, it affects predominantly medium income countries.

Regarding the risk factors, unhealthy diet habits and physical inactivity rise the risk for myocardial infarction and acute stroke.

It is predicted, that by 2020, more than 23 million people will die because of cardiovascular disease, moreover, it will remain as the major cause of death[1].


A  study by Posadas-Romero C. et al [2] was published in the year 2017, which estimates that the prevalence of coronary artery disease in the mexican population is 40% in men and 14% in women, which is considerably different in comparison with the MESA study, which considers the prevalence for men as high as  57.9% and 25% for women in Hispanic population. It is important to notice that the term "hispanic" is not well stablished and it englobes a vast number of latin-american spanish-speaking population, while it ignores their ethnic background.


CT calcium scoring is an imaging tool to determine the burden of calcified plaques in coronary vessels, one of the most used methods is the Agatston score, which gives a weighting factor for each voxel depending on their Hounsfield unit and then multiplied by the area of calcification[3].

Based on the Agatston calcium score, patients are classified as zero,minimal, mild, moderate or severe risk for coronary artery disease[4, 5]. Nonetheless, one limitation of this method is to determine the clinical approach for patients in intermediate cathegories. Therefore, it is important to correlate the coronary plaque burden with other cardiovascular risk tools such as the ACC/ AHA ASCVD risk algorithm in order to give a more specific treatment for each patient.


The purpose of this work is to determine the correlation of CT calcium scoring and clinical cardiovascular risk tools in asymptomatic patients at our Institution in Mexico City.
