Lipoprotein(a) in clinical practice: Risk stratification and therapeutic strategies.
Background: Lipoprotein(a) [Lp(a)] is a primarily genetically determined, causal and independent risk factor for atherosclerotic cardiovascular disease (ASCVD). Lp(a) levels are stable, unaffected by lifestyle, and best measured using isoform-insensitive, molar-based assays. Current guidelines from the European Atherosclerosis Society and U.S. National Lipid Association recommend a one-time Lp(a) measurement in all adults. Cascade testing is advised in affected families.
Results: Elevated Lp(a) levels are associated with increased risk of coronary artery disease, myocardial infarction incidence and recurrence, and aortic stenosis onset and progression. In cerebrovascular disease, high Lp(a) is linked to large artery ischemic stroke incidence and recurrence, as well as poor functional outcomes. Associations with venous thromboembolism are limited to prothrombotic states and extreme Lp(a) concentrations. Elevated levels (≥50 mg/dL or ≥125 nmol/L) should prompt intensified risk factor modification.
Conclusion: There are no currently approved lipid-lowering therapies that substantially reduce Lp(a) levels. Novel agents to lower Lp(a) include antisense oligonucleotides, small interfering ribonucleic acid and small molecules, all of which have shown promising results in phase 2 trials. Ongoing phase 3 trials will evaluate the causal relationship between Lp(a) and ASCVD, and whether lowering Lp(a) reduces cardiovascular outcomes.
期刊介绍:
EJCI considers any original contribution from the most sophisticated basic molecular sciences to applied clinical and translational research and evidence-based medicine across a broad range of subspecialties. The EJCI publishes reports of high-quality research that pertain to the genetic, molecular, cellular, or physiological basis of human biology and disease, as well as research that addresses prevalence, diagnosis, course, treatment, and prevention of disease. We are primarily interested in studies directly pertinent to humans, but submission of robust in vitro and animal work is also encouraged. Interdisciplinary work and research using innovative methods and combinations of laboratory, clinical, and epidemiological methodologies and techniques is of great interest to the journal. Several categories of manuscripts (for detailed description see below) are considered: editorials, original articles (also including randomized clinical trials, systematic reviews and meta-analyses), reviews (narrative reviews), opinion articles (including debates, perspectives and commentaries); and letters to the Editor.
