Insights
Uric acid may drive cardiovascular disease through crystal deposition and inflammation, especially in Asian populations. Further research is needed to explore urate-lowering therapies targeting vascular inflammation.
Area of Science:
- Cardiovascular Disease Research
- Crystal-Induced Inflammation
- Metabolic Disorders
Background:
- Urate-lowering therapies show inconsistent cardiovascular benefits, questioning uric acid's causal role.
- Dual-energy CT reveals monosodium urate crystals in vascular walls, introducing vascular gout.
- Hyperuricemia, common in Asian populations, may promote crystal deposition and inflammation.
Purpose of the Study:
- Reframe uric acid as a mediator of vascular inflammation, not just a marker.
- Investigate the link between uric acid crystals, vascular inflammation, and cardiovascular events.
- Explore therapeutic strategies targeting crystal burden and inflammation in Asian populations.
Main Methods:
- Review of existing literature on urate-lowering trials and cardiovascular outcomes.
- Analysis of dual-energy CT findings regarding monosodium urate crystal deposition.
- Discussion of the role of hyperuricemia and innate immune pathways in vascular disease.
Main Results:
- Inconsistent evidence for urate-lowering drugs in preventing coronary events.
- Demonstration of monosodium urate crystal deposition in atherosclerotic plaques.
- Potential link between hyperuricemia, crystal deposition, and vascular inflammation.
Conclusions:
- Uric acid may play a direct role in cardiovascular disease via crystal-driven inflammation.
- Vascular gout is a relevant concept, particularly in specific populations.
- Future therapies should target crystal burden and inflammation within the vascular wall.
Abstract:
Urate-lowering trials have not consistently demonstrated benefits in preventing coronary events, revealing an interventional gap and challenging the causal role of uric acid in cardiovascular disease. Advances in dual-energy computed tomography have revealed monosodium urate crystal deposition within vessel walls and atherosclerotic plaques, leading to the concept of vascular gout. Persistent hyperuricemia, particularly in Asian populations characterized by urate underexcretion, may facilitate crystal deposition and innate immune pathway activation. These inflammatory processes may promote vascular inflammation, plaque instability, and cardiovascular events. Xanthine oxidase inhibition effectively lowers serum uric acid levels and reduces monosodium urate crystal burden in articular tissues. However, whether urate-lowering therapy reduces monosodium urate crystal deposition and crystal-driven inflammation within the vascular wall remains unknown. Therefore, we aimed to reframe uric acid from a metabolic marker to a mediator of urate crystal-driven vascular inflammation and discuss future therapeutic strategies targeting crystal burden and inflammation in Asian populations.
