Insights
High-density lipoprotein cholesterol (HDL-C) is linked to lower cardiovascular disease (CVD) risk. However, conflicting data challenges HDL
Area of Science:
- Cardiovascular Science and Atherosclerosis Research
Context:
- Epidemiological studies show a strong inverse correlation between high-density lipoprotein cholesterol (HDL-C) levels and cardiovascular disease (CVD) incidence.
- HDL's proposed antiatherogenic functions include reverse cholesterol transport (RCT), anti-inflammatory, antithrombotic, and antioxidant properties.
Purpose:
- To review the current understanding of HDL's role in atherosclerosis in light of recent controversies.
- To reconcile conflicting data regarding HDL's atheroprotective effects.
Summary:
- HDL-C is traditionally considered atheroprotective, making it a target for CVD prevention.
- The failure of torcetrapib, a drug that elevates HDL-C, in preventing CVD, alongside conflicting evidence from animal models and human genetic studies, raises questions about HDL's direct antiatherogenic role.
- This review critically examines the existing knowledge and recent findings surrounding HDL function and its impact on CVD.
Impact:
- Provides a comprehensive overview of the current debate on HDL's role in cardiovascular health.
- Highlights the need for re-evaluation of HDL-C as a therapeutic target for CVD prevention.
- Informs future research directions in lipid metabolism and cardiovascular disease.
Abstract:
Epidemiological studies demonstrate an inverse correlation between plasma HDL-cholesterol (HDL-C) concentration and incidence of cardiovascular disease (CVD). The antiatherogenic role of HDL has been attributed to its anti-inflammatory, antithrombotic and antioxidant properties, besides its participation in the reverse cholesterol transport (RCT), whereby cholesterol from peripheral tissues (including macrophages of the arterial intima) is delivered to the liver for excretion in bile. Due to these actions, HDL-C has evolved as an attractive target for prevention of CVD. However, the failure of torcetrapib, drug that substantially increases HDL-C levels, in preventing CVD and data from studies with animal models and with carriers of monogenic disorders affecting HDL-C levels in humans provide conflicting data about HDL being antiatherogenic. This review addresses the current state of knowledge regarding HDL based on these recent controversies.
