Resumen

The present clinical study aims to identify transcriptomic patterns derived from whole blood samples related to coronary atherotic burden. Additionally, as a secondary analysis, the research team will explore the algorithm's ability to detect the presence of aortic disease and pro-inflammatory cardiometabolic alterations, such as hepatic steatosis and surrogate markers of coronary inflammation.

Descripción detallada

This will be a prospective observational study. A convenience sample will be carried out to include 200 patients who attend the ENERI Medical Institute, La Sagrada Familia Clinic and Sanatorio Mendez with a clinical indication to be evaluated by a CCTA due to suspected CAD or known CAD. The study will have a baseline stage in which a clinical evaluation will be performed, blood samples will be drawn for transcriptome analysis and laboratory analysis. Then, a DNA sample obtained by swabbing the buccal mucose will be taken. Subsequently, the images obtained from the clinically indicated CCTA will be assessed to explore the outcomes of interest. At the end of patient enrollment, biological samples will be sequenced for in silico evaluation of the results. Finally, a 5-year follow-up will be carried out via telephone or email contact to collect data on the incidence of fatal and non-fatal cardiovascular events.
