Abdominal aortic aneurysm (AAA) affects elderly men, with surgery as the main treatment. Research into risk factors and potential drug therapies is ongoing, but more trials are needed.

Area of Science:

Vascular Surgery
Cardiovascular Medicine
Genetics

Background:

Abdominal aortic aneurysm (AAA) is prevalent in elderly men, causing significant mortality.
Current treatments for AAA primarily involve surgical intervention (open or endovascular).

Purpose of the Study:

To review risk factors, serum, and genetic associations of AAA.
To evaluate current and potential future medical treatments for AAA.

Main Methods:

Review of epidemiological and natural history studies.
Analysis of in vitro and animal studies on potential drug targets.
Examination of clinical, serum, and genetic markers for risk stratification.

Main Results:

Smoking cessation, cholesterol, and blood pressure control may reduce AAA development and progression.

Medications targeting inflammation and proteolysis show promise, but evidence for statins, ACE inhibitors, and macrolides is limited.

Identifying at-risk patients using clinical, serum, and genetic data is a focus for targeted treatment.

Conclusions:

Further large-scale randomized controlled trials are essential to establish effective medical treatments for AAA.
Personalized treatment strategies based on patient risk factors are under development.
