Pathophysiology of chronic peripheral ischemia: new perspectives

Area of Science:

• Vascular Biology
• Geriatric Medicine
• Biochemistry

Background:

• Peripheral arterial disease (PAD) is a chronic condition affecting older adults, particularly in developed nations.
• PAD pathogenesis involves complex interactions between hemodynamic changes, inflammation, and oxidative stress.
• Chronic ischemia in PAD impacts peripheral muscle tissue and cellular metabolism.

Purpose of the Study:

• To review the pathophysiological mechanisms of PAD, focusing on hemodynamic, inflammatory, and oxidative stress (OxS).
• To summarize current knowledge on metabolic and oxidative markers associated with PAD.
• To discuss therapeutic strategies aimed at counteracting OxS in PAD patients.

Main Methods:

• Literature review of studies on PAD pathophysiology.
• Analysis of research evaluating metabolic and oxidative markers in PAD.
• Synthesis of findings on therapies targeting OxS in PAD.

Main Results:

• Hemodynamic alterations, inflammation, and OxS are key contributors to PAD progression.
• Specific metabolic and oxidative markers are indicative of PAD severity and impact.
• Therapeutic interventions targeting OxS show potential in managing PAD.

Conclusions:

• Understanding the interplay of hemodynamic, inflammatory, and OxS pathways is crucial for PAD management.
• Further research into novel therapeutic targets for OxS is warranted.
• Development of new drugs focusing on these pathways could significantly benefit PAD patients.
