A score under "33" is considered normal from my research however, the internet says 50 "In summary, a high Lp(a) level, particularly above 50 mg/dL, is a strong indicator of inherited risk for cardiovascular disease, and genetic factors play a significant role in determining an individual's Lp(a) level." but you can inherit CAD without the score being something in particular as well as have a higher score but not inherit the disease. This is where everything else comes into play and there IS a ton more to look at! I have some lipid tests which are amazing and others that are troublesome. But the best thing was getting the physical images of the condition of my arteries (3 clear and 1, which is 1/3 blocked).
As far as the imaging (I don't think mine was with contrast dye): A coronary calcium scan (also called a heart CT scan) is a type of CT scan that specifically images the heart arteries to look for calcium buildup, which can indicate coronary artery disease. This is a visual imaging technique that uses X-rays to create detailed pictures of the heart and blood vessels. Another option is a coronary angiogram, which uses X-rays and a contrast dye to visualize the heart's blood vessels, particularly to detect blockages.
