Scientists Identify Hidden Blood Particle Linked to Increased Cardiovascular Risk
Recent research has identified elevated levels of Lipoprotein(a) [Lp(a)] as a significant risk factor for cardiovascular events, including stroke and death. The study, involving over 20,000 patients from three major NIH studies, found that high Lp(a) levels are linked to increased cardiovascular risk, even when standard cholesterol levels are normal. Lp(a) is a cholesterol-carrying particle that resembles LDL but includes an additional protein, potentially increasing its harmful effects. The study revealed that individuals with Lp(a) levels of 175 nmol/L or higher had a 31% higher risk of major cardiovascular events, a 49% higher risk of cardiovascular death, and a 64% higher risk of stroke. These findings were presented at the Society for Cardiovascular Angiography & Interventions 2026 Scientific Sessions.
