Study Reveals One in Five People May Carry Hidden Genetic Heart Risk
A large-scale study has uncovered a significant yet often undetected genetic risk factor for heart disease. Researchers examined data from over 20,000 individuals and discovered that very high levels of lipoprotein(a), or Lp(a), were strongly associated with increased risk of major cardiovascular events, particularly stroke and death from cardiovascular causes.
Lp(a) is an inherited form of cholesterol-related particles that differs from standard cholesterol measured in routine blood tests. Unlike conventional cholesterol markers, Lp(a) levels are largely determined by genetic factors and typically remain stable throughout a person's life. The study found that approximately one in five people may carry elevated Lp(a) levels, yet this risk factor frequently goes unrecognized because it does not appear in standard lipid panels.
The findings highlight a potential gap in preventive cardiology, as current cardiovascular risk assessments may underestimate danger in individuals with high Lp(a). Unlike elevated LDL cholesterol, which can often be managed through diet, exercise, or medication, Lp(a) is less responsive to lifestyle interventions alone. However, identifying this genetic predisposition could still guide more aggressive management of other modifiable risk factors.
The researchers emphasize that a simple blood test specifically designed to measure Lp(a) levels could help uncover hidden cardiovascular risk, enabling earlier intervention and more personalized treatment strategies for affected individuals.
