In suspected coronary heart disease, which serum analyte would be increased?

Lipid levels, especially LDL cholesterol, are central to coronary heart disease risk. LDL carries cholesterol from the liver to the arteries, and when present in excess it deposits in arterial walls, promoting plaque formation and atherosclerosis. HDL, on the other hand, removes cholesterol from the arteries and is generally protective, so it is not typically elevated as a sign of disease. Sodium and potassium are electrolytes and do not directly indicate CHD risk or presence. Therefore, the analyte most likely increased in suspected CHD is low-density lipoprotein.
