Effects of VEGF on hemodynamics and cardiac function: characterization and mechanisms

Area of Science:

• Cardiovascular Research
• Molecular Biology
• Regenerative Medicine

Background:

• Vascular endothelial growth factor (VEGF) promotes angiogenesis, crucial for treating ischemic diseases.
• VEGF's clinical utility is potentially limited by adverse hemodynamic and cardiac effects.
• Understanding VEGF's impact on cardiovascular function is vital.

Purpose of the Study:

• To review the hemodynamic profile induced by VEGF.
• To elucidate the mechanisms behind VEGF-mediated hemodynamic changes.
• To discuss strategies for preventing or attenuating VEGF's side effects.

Main Methods:

• Literature review focusing on studies investigating VEGF's hemodynamic effects.
• Analysis of data on blood pressure, heart rate, cardiac output, and vascular parameters.
• Examination of the role of nitric oxide in VEGF-induced vasodilation and hyperpermeability.

Main Results:

• VEGF administration is associated with hypotension, tachycardia, and reduced cardiac output and stroke volume.
• Hemodynamic alterations are primarily mediated by VEGF-induced vasodilation and vascular hyperpermeability.
• Nitric oxide plays a key role in mediating these VEGF-induced cardiovascular effects.

Conclusions:

• VEGF's beneficial angiogenic effects are counterbalanced by significant hemodynamic challenges.
• Nitric oxide-dependent vasodilation and hyperpermeability underlie VEGF's adverse cardiovascular impact.
• Developing preventative or attenuating strategies is essential for safe VEGF-based therapies.
