Summary
Coronary collaterals offer protection in coronary artery disease but can have negative effects like restenosis. Quantitative assessment methods are advancing the understanding of their functional relevance in humans.
Area of Science:
- Cardiovascular research
- Human physiology
Context:
- The role of coronary collaterals in human cardiovascular health is not fully understood.
- Previous assessments were qualitative, limiting functional insights.
Purpose:
- To review current research on coronary collaterals in humans.
- To explore their determination, structure, and functional aspects.
- To discuss both beneficial and detrimental effects.
Summary:
- Coronary collaterals can protect against coronary artery disease.
- Well-developed collaterals may increase restenosis risk and cause coronary steal.
- New quantitative methods enable precise functional assessment.
Impact:
- Advances understanding of collateral circulation's functional relevance.
- Informs clinical strategies for managing coronary artery disease.
- Highlights the dual role of collaterals in cardiovascular health.
