Lipoprotein(a) identified as key genetic marker for heart disease risk

Lipoprotein(a), or Lp(a), is a genetic marker linked to an increased risk of heart attack, stroke, and arterial calcification. Unlike standard cholesterol tests that measure LDL, HDL, and triglycerides, Lp(a) requires a specific test as it is not included in routine blood panels.

Medical experts note that high levels of Lp(a) can accelerate the development of atherosclerosis by promoting the formation of fat and cholesterol plaques in the blood vessels and facilitating clot formation. This risk is particularly significant for individuals who experience cardiovascular events at a young age or those with a family history of early heart disease, even if they lack traditional risk factors like high blood pressure or smoking.

Because Lp(a) is largely determined by genetics, proactive screening is recommended for high-risk groups, including those who have experienced recurring vascular blockages despite treatments like stents or bypass surgery. Identifying elevated levels early can help in managing cardiovascular health and preventing serious diagnoses.
