Increasing the complexity of lipoprotein characterization for cardiovascular risk in type 2 diabetes

Area of Science:

• Cardiovascular Medicine
• Metabolic Disorders
• Lipidology

Background:

• Individuals with type 2 diabetes mellitus (T2DM) face a high burden of cardiovascular disease, irrespective of LDL cholesterol levels.
• Persistent atherogenic dyslipidemia, including elevated triglycerides, remnant cholesterol, smaller LDL particles, and reduced HDL cholesterol, contributes to arterial cholesterol accumulation in T2DM.
• The complex interplay between dyslipidemia and atherosclerosis in T2DM necessitates a deeper investigation into lipoprotein composition and functionality.

Purpose of the Study:

• To explore the multifaceted nature of lipoprotein characterization in understanding the hidden cardiovascular risk associated with T2DM.
• To review three distinct levels of lipoprotein analysis, from routine clinical biochemistry to advanced profiling and minor component identification.
• To emphasize the importance of integrating comprehensive lipoprotein data into population studies for ASCVD in T2DM.

Main Methods:

• Review of existing literature on lipoprotein characterization and cardiovascular risk in diabetes.
• Discussion of routine clinical biochemistry parameters relevant to lipid metabolism.
• Exploration of advanced nuclear magnetic resonance (NMR)-based lipoprotein profiling techniques.
• Examination of minor lipoprotein components and physical properties influencing arterial cholesterol deposition.

Main Results:

• Routine clinical biochemistry provides foundational lipid information but may not fully capture atherogenic risk in T2DM.
• Advanced NMR profiling offers detailed insights into lipoprotein particle size, number, and composition.
• Identification of specific lipoprotein subclasses and properties can elucidate cholesterol accumulation mechanisms in individuals with normal LDLc.

Conclusions:

• A comprehensive understanding of lipoprotein behavior, encompassing routine, advanced, and detailed analyses, is crucial for managing cardiovascular risk in T2DM.
• Integrating multi-layered lipoprotein data into population studies is essential for accurately assessing ASCVD risk in diabetic populations.
• Biotechnological advancements are needed to facilitate large-scale, methodologically diverse lipoprotein parameter determination for widespread clinical application.
