[Inducing collaterals in due time. Arteriogenesis as a preventive principle]

Area of Science:

• Cardiovascular Biology
• Vascular Medicine
• Regenerative Medicine

Context:

• Diffuse occlusive vessel disease presents significant therapeutic challenges.
• Arteriogenesis, the growth of collateral vessels, is a key mechanism for restoring blood flow.
• Current pro-arteriogenic therapies face limitations due to the natural timeline of arteriogenesis.

Purpose:

• To explore therapeutic strategies for stimulating collateral vessel growth (arteriogenesis).
• To investigate the limitations of unifactorial therapies, such as cytokine application.
• To evaluate the potential of mechanical inducers, specifically fluid shear stress, as a therapeutic addition.

Summary:

• Arteriogenesis is a therapeutic target for occlusive vascular disease.
• Monocyte function stimulation via cytokines has shown limited success in unifactorial approaches.
• Mechanical induction of arteriogenesis through fluid shear stress, achievable via physical training or external counterpulsation (EECP), is a promising strategy.

Impact:

• Identifies fluid shear stress as a feasible mechanical inductor for arteriogenesis.
• Highlights external counterpulsation (EECP) as a promising clinical method for enhancing collateral vessel growth.
• Suggests a potential for improved therapeutic outcomes in patients with diffuse occlusive vessel disease.
