Cardiovascular Risk in Patients with Inflammatory Bowel Diseases-The Role of Endothelial Dysfunction

Area of Science:

• Gastroenterology and Cardiology
• Pathophysiology of Chronic Inflammatory Diseases

Background:

• Inflammatory bowel disease (IBD) is linked to a higher risk of cardiovascular disease (CVD), but the underlying mechanisms are not fully understood.
• Cardiovascular pathology in IBD patients remains understudied, with no definitively established direct link between cardiovascular events and IBD.
• Key contributing factors include inflammation, gut microbiota alterations, endothelial dysfunction, thrombogenicity, and increased barrier permeability.

Purpose of the Study:

• To review the mechanisms driving endothelial dysfunction in IBD.
• To explore disorders of the gut-vascular barrier structure and function in IBD's cardiovascular manifestations.

Main Methods:

• Literature review focusing on the interplay between IBD, endothelial function, and cardiovascular health.
• Analysis of existing research on inflammation, gut microbiota, and barrier integrity in IBD-associated CVD.

Main Results:

• Endothelial dysfunction is a shared pathogenic factor in both IBD and atherosclerotic CVD.
• This dysfunction is a critical driver for the development and progression of cardiovascular pathology in IBD patients.
• Disruptions in the gut-vascular barrier are integral to IBD's cardiovascular complications.

Conclusions:

• Endothelial dysfunction and gut-vascular barrier impairment are central to cardiovascular manifestations in IBD.
• Understanding these mechanisms is crucial for managing CVD risk in individuals with IBD.
• Further research is warranted to establish direct links and develop targeted interventions.
