Targeting Platelet Activation in Abdominal Aortic Aneurysm: Current Knowledge and Perspectives

Area of Science:

• Vascular Biology
• Hematology
• Cardiovascular Research

Background:

• Abdominal aortic aneurysm (AAA) is a serious vascular condition with incompletely understood mechanisms.
• Platelets are increasingly recognized for their role in vascular diseases beyond hemostasis and thrombosis.
• Inflammatory processes and aortic wall remodeling are key factors in AAA pathogenesis.

Purpose of the Study:

• To summarize the intricate relationship between platelet activation and the development of abdominal aortic aneurysms.
• To explore the role of platelets in promoting thrombus formation and inflammatory cell accumulation in AAA.
• To highlight the potential of platelet count and heterogeneity as diagnostic and prognostic markers for AAA.

Main Methods:

• Review of existing literature on platelet function in vascular pathology.
• Analysis of the impact of turbulent blood flow on platelet activation in aneurysms.
• Examination of studies correlating platelet parameters with AAA prediction, diagnosis, and prognosis.

Main Results:

• Platelet activation, mediated by receptors and secreted factors, contributes to thrombus formation and inflammation in AAA.
• Turbulent blood flow within aortic aneurysms actively promotes platelet activation and aggregation.
• Platelet count and heterogeneity are significant indicators for predicting, diagnosing, and determining the prognosis of AAA.

Conclusions:

• Platelet activation is a crucial component in the pathogenesis of abdominal aortic aneurysms, impacting vessel wall integrity.
• Understanding platelet dynamics offers potential for novel therapeutic strategies and improved clinical management of AAA.
• Further research into platelet mechanisms can enhance diagnostic accuracy and prognostic assessment for AAA patients.
