Progress in murine models of ruptured abdominal aortic aneurysm

Area of Science:

• Cardiovascular Research
• Pathophysiology
• Animal Models

Background:

• Abdominal aortic aneurysm (AAA) is a prevalent, life-threatening aortic dilation in aging populations.
• AAA expansion is unpredictable and rupture carries a high mortality rate (~80%).
• Current treatments lack the ability to halt AAA progression, necessitating research into its underlying mechanisms.

Purpose of the Study:

• To review established murine models of ruptured abdominal aortic aneurysm.
• To discuss the strengths and limitations of various AAA experimental models.
• To highlight the utility of animal models in understanding AAA pathogenesis.

Main Methods:

• Literature review of established murine models for inducing and studying AAA.
• Analysis of distinct AAA-inducing methodologies and their impact on disease course.
• Evaluation of model relevance to AAA pathophysiology and rupture.

Main Results:

• Multiple murine models exist for AAA research, each with unique characteristics.
• Different models exhibit varying disease progression and rupture rates.
• No single model fully replicates the complexity of human AAA.

Conclusions:

• Murine models are crucial for investigating AAA pathogenesis and identifying therapeutic targets.
• Understanding the strengths and weaknesses of each model is key for effective research.
• Further research using appropriate animal models is needed to develop treatments for AAA.
