Therapeutic strategies targeting endothelial function in humans: clinical implications

Area of Science:

• Vascular Biology
• Cardiovascular Medicine
• Oxidative Stress Research

Background:

• Persistent oxidative stress in the vascular wall contributes to endothelial dysfunction.
• Endothelial dysfunction is a key pathological process in various cardiovascular diseases.
• Reactive oxygen species (ROS) production is regulated by oxidases and mitochondria.

Purpose of the Study:

• To review therapeutic interventions aimed at increasing nitric oxide (NO) bioavailability.
• To explore strategies for improving endothelial function and long-term cardiovascular outcomes.
• To assess the clinical benefits of various approaches targeting NO pathways.

Main Methods:

• Review of current therapeutic strategies for enhancing NO synthesis or reducing its oxidative inactivation.
• Analysis of the efficacy of angiotensin converting enzyme inhibitors and statins.
• Exploration of novel approaches including folate, tetrahydrobiopterin, and gene therapy.

Main Results:

• Angiotensin converting enzyme inhibitors and statins demonstrate significant promise in improving endothelial function and cardiovascular outcomes with long-term use.
• Targeting NO synthesis via endothelial nitric oxide synthase (eNOS) coupling modulation (e.g., folates, tetrahydrobiopterin) is an emerging strategy.
• Gene therapy also shows emerging evidence for improving endothelial function.

Conclusions:

• Therapeutic interventions increasing NO bioavailability hold potential for improving cardiovascular health in diverse populations.
• While promising, the long-term direct clinical benefits of novel strategies like eNOS modulation and gene therapy require further clarification.
• Optimizing NO bioavailability remains a critical target for managing endothelial dysfunction and cardiovascular disease.
