A mathematical model of aortic aneurysm formation.

Area of Science:

• Biomedical Engineering
• Cardiovascular Research
• Mathematical Modeling

Background:

• Abdominal aortic aneurysm (AAA) is a life-threatening condition characterized by aortic enlargement, with rupture carrying a high mortality risk.
• Predicting AAA growth is crucial for timely intervention and patient management.
• Interleukin-6 (IL-6) is implicated in AAA pathogenesis and may serve as a prognostic biomarker.

Purpose of the Study:

• To develop a mathematical model for predicting abdominal aortic diameter growth in patients with AAA.
• To integrate initial aneurysm diameter and serum IL-6 concentration into the predictive model.
• To provide a tool for guiding patient monitoring frequency based on predicted AAA growth.

Main Methods:

• Development of a mathematical model based on a system of partial differential equations.
• The model incorporates the hyperelastic properties of the aortic wall's media.
• The model utilizes initial aortic diameter and serum IL-6 levels as input parameters.

Main Results:

• The developed mathematical model predicts the growth of the abdominal aorta diameter over time.
• The model correlates serum IL-6 concentration with the rate of AAA progression.
• The model provides quantitative predictions to inform clinical monitoring strategies.

Conclusions:

• A novel mathematical model effectively predicts AAA diameter growth.
• Serum IL-6 levels are a valuable factor in predicting AAA progression.
• This model can enhance personalized monitoring protocols for AAA patients, potentially reducing rupture risk.
