This study is being done to learn more about Lipoprotein(a) (Lp(a) values in people with known history of Atherosclerotic Cardiovascular Disease (ASCVD). Lipoprotein(a) is a particle that carries cholesterol in the blood. ASCVD is a type of thickening or hardening of the arteries caused by a build up of plaque in the walls of arteries. Plaque is made up of substances such as fats and cholesterol. Plaque can cause blockages in the arteries which could result in a heart attack. High levels of Lp(a) are directly associated with a higher risk of cardiovascular events such as heart attacks or aortic stenosis.

Participation in this study will last up to 2 weeks and involve data collection and a blood draw for a Lipoprotein(a) level unless you've had a level checked in the past. You will be informed of your Lipoprotein(a) level.
