New findings from more than 20,000 patients across three major NIH studies suggest that elevated Lipoprotein(a) [Lp(a)] may contribute to cardiovascular risk that remains even after standard treatment. The results indicate that people with high Lp(a) may benefit from more aggressive efforts to reduce other heart disease risk factors.
The late-breaking findings were presented at the Society for Cardiovascular Angiography & Interventions (SCAI) 2026 Scientific Sessions and Canadian Association of Interventional Cardiology/Association Canadienne de cardiologie d'intervention (CAIC-ACCI) Summit in Montreal.
What Is Lipoprotein(a)?
Lp(a) is a cholesterol-carrying particle found in the blood. It resembles LDL, often called "bad" cholesterol, but includes an additional protein that may make it more likely to contribute to cardiovascular disease.
High Lp(a) levels are largely determined by genetics. They can increase cardiovascular risk even when more familiar cholesterol measurements fall within normal ranges. Approximately one in five people has high Lp(a), yet most people with elevated levels do not know it because the condition typically causes no symptoms.
