Heart disease is often linked to common factors like high cholesterol and blood pressure, but experts say there is more beneath the surface. One lesser-known contributor gaining attention is lipoprotein(a), also known as Lp(a), a type of cholesterol particle that can significantly increase cardiovascular risk without obvious symptoms.
According to Dr Jeremy London, a highly experienced heart surgeon, Lp(a) is a variation of LDL cholesterol that includes an additional protein component. This structural difference makes it more harmful, as it can accelerate plaque formation in arteries, trigger inflammation, and even increase the likelihood of blood clotting.
What makes Lp(a) particularly important is its strong genetic link. Experts estimate that around 80 to 90 percent of Lp(a) levels are inherited, meaning lifestyle changes alone cannot significantly reduce it. In fact, approximately one in five individuals may have elevated levels without being aware of it.
Despite its genetic nature, having high Lp(a) does not mean heart disease is inevitable. Instead, specialists emphasize managing overall cardiovascular health to reduce total risk. This includes controlling LDL cholesterol levels, maintaining healthy blood pressure and blood sugar, and focusing on broader metabolic markers such as Apolipoprotein B.
Lifestyle choices still play a critical role in managing heart health. Regular physical activity, a balanced diet, quality sleep, and avoiding smoking are essential steps that can help offset the risks associated with elevated Lp(a). Building strong social connections and reducing stress also contribute positively to heart health.
Medical research is ongoing, and new treatments are being developed that specifically target Lp(a) levels. However, experts note that more evidence is needed to confirm whether lowering Lp(a) directly reduces the risk of heart attacks.
Understanding genetic risk factors like Lp(a) can help individuals take proactive steps toward better heart health, even when certain elements are beyond direct control.
