Infectious burden and atherosclerosis: A clinical issue

Area of Science:

• Cardiovascular Medicine
• Infectious Diseases
• Immunology

Background:

• Atherosclerotic cardiovascular diseases are the primary global cause of mortality.
• Chronic inflammation and multifactorial etiology characterize atherosclerosis.
• The role of infectious agents, termed "infectious burden," in atherosclerosis is increasingly recognized.

Purpose of the Study:

• To review the mechanisms by which infectious agents contribute to atherosclerosis.
• To highlight the complexity of multiple pathogens acting synergistically.
• To emphasize the need for further research into the infectious-atherosclerosis link.

Main Methods:

• Literature review of studies investigating infectious agents and atherosclerosis.
• Analysis of direct and indirect pathogenic mechanisms.
• Examination of molecular mimicry as a contributing factor.

Main Results:

• Infectious agents can directly damage the arterial wall, causing endothelial dysfunction and promoting lesion development.
• Some pathogens induce systemic inflammation, indirectly harming the vascular wall.
• Molecular mimicry is an additional pathway through which infections promote atherosclerosis.

Conclusions:

• The cumulative "infectious burden" from multiple pathogens may amplify atherosclerosis development.
• Understanding the interplay between various microorganisms and atherosclerosis is complex but vital.
• Increased research and awareness are necessary to elucidate these interactions and improve prevention/treatment strategies.
