Bridging the Gap: Elevating Lipoprotein(a) Screening in Community Health Centers

Elevated lipoprotein(a), a genetically inherited and independent risk factor for atherosclerotic cardiovascular disease, is frequently overlooked in routine screening protocols, especially within resource-challenged community health centers.

Despite advances in recognizing traditional cardiovascular risk factors, lipoprotein(a) remains underappreciated for its causal role in plaque formation and thrombosis. The 2018 AHA/ACC guidelines identify elevated lipoprotein(a) (Lp(a)) levels as a risk-enhancing factor for atherosclerotic cardiovascular disease, although specific residual risk percentages are detailed in the study "Lipoprotein(a) and Coronary Heart Disease: Meta-Analysis of Prospective Studies," which quantifies the contribution of Lp(a) to cardiovascular risk. Routine assessment of Lp(a) often remains confined to tertiary centers, leaving community-based clinicians without a clear pathway for Lp(a) measurement amid competing demands and budget constraints. Innovative strategies in cardiovascular disease screening are crucial to bridge this gap.

Recent initiatives to boost Lp(a) screening within community health centers represent a strategic pivot in preventative cardiology. Such screening initiatives exemplify community health initiatives that are transforming approaches to cardiovascular disease screening, embedding Lp(a) assessment into annual risk panels and equipping nursing teams with targeted protocols to democratize access to advanced lipid testing and heighten clinician awareness of this potent risk marker.

Community health centers serve as effective platforms for broadening access to Lp(a) assessment. With existing ties to underserved populations, these centers can close the detection gap by offering point-of-care testing and dedicated education sessions that contextualize Lp(a) within the spectrum of cardiovascular risk factors. Early experiences in urban and rural pilot sites have doubled the identification rate of elevated Lp(a), triggering timely lifestyle interventions and therapeutic adjustments.

As noted above, expanding Lp(a) screening aligns with broader community health strategies and holds promise for improving cardiovascular outcomes. Detecting elevated Lp(a) levels early allows clinicians to intensify risk-reduction efforts—ranging from aggressive LDL-lowering regimens to referral for emerging Lp(a)-targeted therapies in clinical trials. This community-driven approach can transform practice patterns, shifting prevention upstream and narrowing disparities in cardiovascular disease burden.

Key Takeaways:

• Elevated lipoprotein(a) is a significant, often underrecognized risk factor for atherosclerotic cardiovascular disease.
• Embedding Lp(a) assessment in community health centers enhances equity in cardiovascular disease screening.
• Early detection of high Lp(a) levels enables proactive risk-reduction strategies and tailored patient counseling.
• Community-based screening initiatives can shift preventative cardiology upstream and reduce care disparities.
