Sex difference is a risk factor for abdominal aortic aneurysm (AAA) formation yet the reason for male predominance remains unclear. Androgen and the androgen receptor (AR) influence the male sex difference, indicating that AR signaling may affect AAA development. Using angiotensin II–induced AAA in apolipoprotein E null mouse models (82.4% AAA incidence), we found that mice lacking AR failed to...
Abdominal aortic aneurysm (AAA) is a major cause of morbidity and mortality; however, the mechanisms that are involved in disease initiation and progression are incompletely understood. Extracellular matrix proteins play an integral role in modulating vascular homeostasis in health and disease. Here, we determined that the expression of the matricellular protein CCN3 is strongly reduced in rode...
Abdominal aortic aneurysm (AAA) is an inflammatory vascular disorder with high mortality. Accumulating evidence shows that toll-like receptor 2 (TLR2) plays a critical role in the regulation of wound-repairing process after tissue injury. We wondered if TLR2 signaling contributed to the pathogenesis of AAA and that targeting TLR2 would attenuate AAA development and progression. In this study, e...
CONTEXT Among patients with abdominal aortic aneurysm (AAA) who have high operative risk, repair is usually deferred until the AAA reaches a diameter at which rupture risk is thought to outweigh operative risk, but few data exist on rupture risk of large AAA. OBJECTIVE To determine the incidence of rupture in patients with large AAA. DESIGN AND SETTING Prospective cohort study in 47 Veteran...
Abdominal aortic aneurysm (AAA) is a vascular disease that results in rupture of the abdominal aorta. The risk factors for the development of AAA include smoking, male sex, hypertension, and age. AAA has a high mortality rate, but therapy for AAA is restricted to surgery in cases of large aneurysms. Clarifying the effect of dietary food on the development of AAA would be helpful for patients wi...
BACKGROUND In a number of relatively small-size studies, investigators have measured and compared circulating interleukin-6 (IL-6) levels in cases with abdominal aortic aneurysm (AAA) and controls without AAA to assess its possible role in the pathogenesis or progression of AAA. To summarize the present evidence for an association between circulating IL-6 levels and AAA presence, we performed a...
Abdominal Aortic Aneurysms Human Studies The incidence of abdominal aortic aneurysms (AAA) is increasing in the elder population. Independent risk factors for AAA include not only aging but also male and smoking, whereas some risk factors such as hypertension and hypercholesterolemia have not been consistently demonstrated to be independent risk factors. There are several recent population stud...
BACKGROUND Acute kidney injury (AKI) is a severe complication associated with abdominal aortic aneurysm (AAA) repair. In this study, we evaluated the incidence, risk factors and in-hospital mortality of AKI in patients after the AAA repair surgery. METHODS A total of 314 Chinese AAA patients who underwent endovascular aneurysm repair (EVAR) or open aneurysm repair (OPEN) were enrolled in this...
Background—Recent studies from Australia, New Zealand, and Sweden have reported declines in abdominal aortic aneurysm (AAA) incidence, prevalence, and mortality. This finding may have important implications for screening programs. This study determined trends in AAA incidence and mortality in England and Wales. Methods and Results—Cause-specific mortality data for England and Wales were obtaine...
