Exploring the Association between Low-Density Lipoprotein Subfractions and Major Adverse Cardiovascular Outcomes-A...

Area of Science:

• Cardiology
• Biochemistry
• Genetics

Background:

• Cardiovascular disease (CVD) is a leading global cause of death, with atherosclerosis as its primary manifestation.
• Low-density lipoproteins (LDL) are established cardiovascular risk factors, with small, dense LDL particles identified as particularly atherogenic.
• Understanding LDL subfractions is crucial for identifying high-risk individuals and developing targeted therapies.

Purpose of the Study:

• To comprehensively review the association between various LDL subfractions and the risk of major adverse cardiovascular events.
• To evaluate the physiopathological characteristics, chemical composition, and predictive value of LDL subfractions for long-term cardiovascular risk.
• To explore the potential of LDL subfractions as prognostic biomarkers and targets for novel lipid-lowering strategies.

Main Methods:

• Literature review assessing genetical and clinical features of LDL subfractions.
• Analysis of physiopathological characteristics and chemical composition of different LDL subfractions.
• Evaluation of the global ability of LDL subfractions to predict long-term cardiovascular risk.

Main Results:

• Small, dense LDL subfractions are more frequently associated with an increased risk of atherosclerotic cardiovascular disease.
• LDL subfractions possess distinct physiopathological properties and chemical compositions that influence their atherogenicity.
• Current evidence suggests LDL subfractions have significant potential as accurate prognostic biomarkers.

Conclusions:

• Further research is needed to define optimal LDL-C levels for primary and secondary CVD prevention.
• Implementation of routine LDL subfraction testing could enhance cardiovascular risk assessment beyond traditional factors.
• Targeting specific LDL subfractions may offer novel therapeutic avenues for lipid-lowering interventions.
