A National, Multicenter, Prospective Observational Study to Measure Abdominal Aortic Diameter in Women Aged 50 and Older

What this Trial Is About

This research aims to study abdominal aortic diameter specifically in females aged 50 years or older. It evaluates biometric data of the aorta and iliac vessels along with demographic and health history related to reproductive factors such as menarche, pregnancy, infertility, and menopause. The study focuses on understanding the ultrasound measurements of the abdominal aorta and identifying female-specific risk factors for abdominal aortic diseases including aneurysms and atherosclerosis. Measurements of the aorta will be done using ultrasound by placing the probe perpendicular to the aortic axis and recording diameters in both antero-posterior and lateral directions. Both inner-to-inner and outer-to-outer diameters of the infrarenal aortic segment will be measured, along with assessments for the presence of thrombus and calcifications, and measurements of the common iliac arteries. The study follows standard clinical measurement protocols. Participants will provide biometric data and health history related to cardiovascular and reproductive health. Researchers will analyze ultrasound images and collected data to define typical abdominal aortic diameters in women and explore risk factors linked to aortic disease. The main measurement outcome is the ultrasound diameter of the infrarenal aortic segment. This observational study includes safety monitoring and will continue until July 2027, with the total participation duration varying by individual.
