Lipoprotein(a) [Lp(a)] is a causal risk factor for cardiovascular disease, but its impact on long-term coronary plaque progression remains unclear. This study synthesizes evidence from CCTA, IVUS, and OCT to clarify the relationship between high-risk Lp(a) and coronary plaque burden and high-risk plaque features. We conducted a comprehensive search of multiple databases up to July 2025 for studies evaluating Lp(a) and atherosclerotic plaque progression. Statistical analysis was performed using a random-effects model in RevMan 5.4, reporting odds ratios (OR) and mean differences (MD) with 95% confidence intervals (CI). The protocol is registered in PROSPERO (CRD420251113955). Our final analysis included 16 studies comprising 19,822 participants with a mean age of 62 years and a median imaging follow-up ranging from 10 months to 10.2 years. On analysis, high-risk Lp(a) levels were significantly associated with the presence of coronary plaque (OR 1.53; 95% CI, 1.03-2.29; p = 0.04) compared with low Lp(a) levels. Additionally, patients with elevated Lp(a) exhibited significantly greater progression in percent atheroma volume (ΔPAV) than those with low levels (MD 4.31%; 95% CI, 1.08-7.53; p = 0.009). Subgroup analysis by plaque phenotype revealed a statistically significant increase in low-attenuation plaque (LAP) presence among individuals in the high-risk Lp(a) category (OR 1.92; 95% CI, 1.13-3.27; p = 0.02). High-risk Lp(a) is associated with greater coronary plaque prevalence, accelerated progression, and increased LAP. These findings underscore Lp(a) as a driver of high-risk, rupture-prone plaques and a critical biomarker and potential therapeutic target in cardiovascular risk management. Show less

Elevated lipoprotein(a) [Lp(a)] is an independent, causal risk factor for atherosclerotic cardiovascular disease (ASCVD), yet testing remains low. As our health system has expanded its efforts to increase Lp(a) awareness, we evaluated testing rates and their impact on care. Lp(a) testing rates were collected through electronic health record queries between 1/1/2022 to 12/31/2024. Baseline demographics, ASCVD status, Lp(a) testing rates by specialty, lipid lowering therapy (LLT) prescriptions and number of cardiology referrals were collected. 450,412 outpatients had ≥1 lipid panel order and 3.7 % ( While Lp(a) testing was low, it increased substantially over time. High risk Lp(a) levels were found irrespective of ASCVD status and were associated with more aggressive treatment. Systematic strategies to increase Lp(a) awareness and testing are warranted to mitigate cardiovascular risk. Show less

There is a direct relationship between the duration and level of exposure to low density lipoprotein cholesterol (LDL-C) levels over one's lifespan and cardiovascular events. Early treatment to lower elevated LDL-C is crucial for better outcomes with multiple therapies currently available to reduce atherogenic lipoproteins. Statins remain the foundation of LDL-C lowering therapy as one of the most cost-effective drugs to reduce atherosclerotic events (ASCVD) and mortality. Nonetheless, LDL-driven goal attainment remains suboptimal globally, highlighting a considerable need for non-statin therapies to address residual risk related to statin intolerance, non-adherence, and inherited lipoprotein disorders. LDL-C lowering interventions beyond statins include ezetimibe, PCSK9 monoclonal antibodies, inclisiran and bempedoic acid with specific guideline recommendations as to when to consider each. For patients with homozygous familial hypercholesterolemia requiring more advanced therapy, lomitapide and evinacumab are available, providing mechanisms that are not LDL receptor dependent. Lipoprotein apheresis remains an effective option for clinical familial hypercholesterolemia as well as elevated lipoprotein (a). There are investigational therapies being explored to add to our current armamentarium including CETP inhibitors, a third-generation PCSK9 inhibitor (small recombinant fusion protein oral PCSK9 inhibitor) and gene editing which aims to directly restore or disrupt genes of interest at the DNA level. This article is a brief review of the pharmacotherapy options beyond statins for lowering LDL-C and their impact on ASCVD risk reduction. Our primary aim is to guide physicians on the role these therapies play in achieving appropriate LDL-C goals, with an algorithm of when to consider each based on efficacy, safety and outcomes.
