Does high lipoprotein(a) (Lp(a)) concentration causally increase the risk of ischemic cardiovascular disease, and does it represent an unmet medical need?
Lipoprotein(a), a review (Clin Chem 2021, PMID 33236085) — high Lp(a) concentrations are present in 10%-20% of the population, affecting an estimated >1 billion individuals worldwide. The review highlights the need for randomized cardiovascular outcome trials to provide final evidence of causality and assess the clinical benefit of novel Lp(a) lowering therapies, indicating that current evidence, while strong, is not definitive for treatment decisions.

High lipoprotein(a) levels are causally linked to increased cardiovascular disease risk, but more research is needed to confirm treatment benefits.
The question
Does high lipoprotein(a) (Lp(a)) concentration causally increase the risk of ischemic cardiovascular disease, and does it represent an unmet medical need?
What they tested
The review implicitly hypothesizes that high Lp(a) concentrations are causally linked to increased cardiovascular disease risk and may represent an unmet medical need requiring treatment.
How they did it
This is a narrative review summarizing evidence from mechanistic, observational, and large genetic epidemiologic studies regarding the causality of high Lp(a) concentrations in cardiovascular disease. It also discusses Lp(a) measurement methods and future treatment options.
What they found
Evidence from mechanistic, observational, and genetic studies supports a causal role of Lp(a) in the development of cardiovascular disease, including coronary heart disease, peripheral arterial disease, aortic valve stenosis, and likely ischemic stroke. High Lp(a) concentrations predict 2- to 3-fold increases in risk for myocardial infarction, peripheral arterial disease, and aortic valve stenosis. High Lp(a) concentrations are present in 10%-20% of the population, affecting an estimated >1 billion individuals worldwide.
| Myocardial Infarction | 2.5 | |
|---|---|---|
| Peripheral Arterial Disease | 2.5 | |
| Aortic Valve Stenosis | 2.5 |
High lipoprotein(a) concentrations predict 2- to 3-fold increases in risk for myocardial infarction, peripheral arterial disease, and aortic valve stenosis. The chart uses the midpoint value of 2.5 for illustration.
What it means
High lipoprotein(a) concentrations are causally linked to an increased risk of cardiovascular diseases such as myocardial infarction, peripheral arterial disease, and aortic valve stenosis. Standardized Lp(a) measurements are crucial, and randomized cardiovascular outcome trials are necessary to confirm causality and evaluate the clinical benefit of Lp(a)-lowering therapies.
Limitations
The review highlights the need for randomized cardiovascular outcome trials to provide final evidence of causality and assess the clinical benefit of novel Lp(a) lowering therapies, indicating that current evidence, while strong, is not definitive for treatment decisions.
