Abstract

To evaluate the aortic wall distensibility (AD) in hemodialysis patients, we measured AD at the ascending aorta using cine magnetic resonance imaging in 10 hemodialysis patients (HDP) and 10 normal controls (NC). Age and sex were matched in HDP and NC. Transverse image of the aorta was measured in the maximum and minimum frames. AD was calculated from the following formula: (Max. area — Min. area)/Min. area − pulse pressure). Although systolic blood pressure, diastolic blood pressure, and minimum area of ascending aorta showed no significant differences between HDP and NC, AD was significantly lower in HDP (2.95 ± 0.87 − 10−3 mmHg−1) than in NC (6.61 ± 3.1 2× 10−3 mmHg−1) (p<0.01). It is suspected that hemodialysis patients have advanced aortic wall sclerosis.
