From Genes to Diagnosis: Polygenic Risk Scores Enter the Arena for Peripheral Artery Disease
A new study published in the European Heart Journal explores the development and application of polygenic risk scores (PRS) for peripheral artery disease (PAD). Leveraging large-scale biobank data, this research focuses on translating genetic discoveries into predictive tools. The work aims to identify individuals at high genetic risk for PAD, a condition characterized by atherosclerosis in the limbs, which is a major source of cardiovascular morbidity and shares risk factors with coronary artery disease. The development of a robust PRS could shift the paradigm from reactive treatment to proactive, genetically-informed risk stratification and early intervention.
Why it might matter to you: For cardiology professionals focused on cardiovascular risk prediction and prevention, this represents a significant step toward precision medicine. Integrating a validated PAD polygenic risk score into clinical assessment could refine risk models beyond traditional factors like hypertension and lipid levels. This may lead to earlier identification of at-risk patients, allowing for intensified surveillance and targeted lifestyle or pharmacological interventions to prevent disease progression and adverse cardiac events.
