Lipoprotein(a) is a subtype of lipoproteins in the blood, consisting of a combination of lipids and proteins. Elevated Lipoprotein(a) levels in the blood can increase the risk of cardiovascular diseases, particularly atherosclerosis and heart attack. Lipoprotein(a) can deposit in the walls of the arteries and contribute to the formation of plaques, leading to a narrowing of the arteries and an increased risk of cardiovascular diseases. Measuring Lipoprotein(a) is important for assessing the risk of cardiovascular diseases and can aid in decision-making regarding preventive measures and treatments.
