The goal of this observational study is to evaluate whether serum Lipoprotein(a) \[Lp(a)\] levels are associated with coronary artery calcium (CAC) score measured by multi-slice computed tomography (MSCT) in adults undergoing cardiac risk assessment. The main questions it aims to answer are: * Is there a correlation between elevated Lp(a) levels and higher CAC scores? * Does Lp(a) provide additional predictive value for subclinical atherosclerosis beyond traditional cardiovascular risk factors? Participants will: * Undergo a non-contrast MSCT scan to measure CAC score. * Provide a blood sample for measurement of Lp(a) and routine lipid profile. * Have baseline clinical and demographic data collected, including cardiovascular risk factors.
