At April 25, 2024, the healthcare community is on the brink of a significant shift in cholesterol screening protocols. For decades, a pivotal blood test has lurked in the shadows of routine medical exams, seldom utilized despite its availability and affordability. This test, targeting the lipoprotein(a) or Lp(a) particle, is now poised to become a standard element in detecting hidden cardiovascular risks.

Lipoprotein(a) has flown under the radar in standard cholesterol checks, despite the profound implications it holds for heart health. Nathan D. Wong, PhD, the principal investigator of a landmark study published in the Journal of the American College of Cardiology, highlights a startling reality: a staggering one in five individuals harbor dangerously high levels of Lp(a) due to genetic factors. These levels can ominously elevate the risk of severe heart complications, unbeknownst to those who might only consider their total or LDL cholesterol readings.
The importance of Lp(a) testing has been corroborated by an extensive and ethnically diverse study led by Wong. The findings indicate that individuals with elevated Lp(a) levels could face double the risk of serious heart issues compared to those with lower levels. In light of these findings, for the first time, a leading U.S. medical group has advocated for universal Lp(a) testing at least once in every adult’s lifetime, signaling a paradigm shift in cardiovascular risk assessment.
Gregory G. Schwartz, MD, PhD, a prominent figure in cardiology at the University of Colorado and the Rocky Mountain Regional VA Medical Center, stresses the imperative to broaden awareness of Lp(a) beyond the circle of specialists to general practitioners and the public. The insights from ongoing research are bringing us closer to demystifying this critical yet overlooked risk factor, discovered as far back as 1963.
The urgency of addressing high Lp(a) levels is underpinned by the potential of pioneering treatments on the horizon, expected within the next couple of years. Meanwhile, experts like P. Barton Duell, MD, from Oregon Health & Science University and a board member of the National Lipid Association, urge patients to proactively request Lp(a) testing. This proactive approach is crucial, particularly for individuals with a family history of elevated Lp(a), as the trait is hereditary.
The recent study involving 27,000 participants devoid of prior atherosclerotic cardiovascular disease diagnosis—spanning conditions from heart attacks to strokes—has shed light on the critical role of Lp(a) as a hidden catalyst for these life-threatening conditions. These findings are particularly alarming given the comparative analysis indicating that Lp(a) could be substantially more atherogenic than LDL cholesterol, the traditionally recognized “bad” cholesterol.
This growing body of research not only recalibrates our understanding of heart disease risk factors but also underscores the need for a more nuanced approach in the medical community regarding cardiovascular prevention strategies, especially among high-risk groups, including those with diabetes.
As the medical community awaits the potential game-changing treatments for high Lp(a), the consensus is clear: understanding and testing for Lp(a) levels are indispensable in the holistic management of cardiovascular health. This approach could ultimately reshape preventive strategies and therapeutic interventions, offering hope for those at elevated risk due to this potent yet previously underappreciated factor.
