Clinical Trial Summary

The primary goal of this study is to determine the prevalence of undiagnosed asymptomatic coronary artery disease (CAD) in Kalamazoo and its neighboring areas using Coronary Computed Tomography (CCTA) and Coronary Artery Calcium Score (CACS) to assess if asymptomatic CAD is widespread enough to warrant implementation of CCTA as a routine screening tool. Additionally, this study will use the CCTA results to evaluate several methods of assessing CAD risk in the asymptomatic population including Framingham Risk Score (FRS) and Reynold's Risk Score, Biomarkers (High sensitivity C-Reactive Protein, Fibrinogen, Vertical Auto Profile, oxidized Low Density Lipoprotein (LDL), Apolipoprotein A1 (ApoA1), Apolipoprotein B1 (ApoB1), Vitamin D, Homocysteine) as well as a large panel of genetic markers of atherosclerosis and dyslipidemia.
