Aortic Stiffening, Aortic Blood Flow Reversal, and Renal Blood Flow.
N ormal arterial aging is characterized by arterial enlargement , wall thickening, and stiffening, which predominates at large arteries. 1 Patients with chronic kidney disease (CKD) have an early vascular aging, 2 characterized by an accelerated arterial enlargement and stiffening, which occurs in parallel with the decline in glomerular filtration rate (GFR). 3 The relationships between central...

متن کاملProximal aortic stiffening in Turner patients may be present before dilation can be detected: a segmental functional MRI study
BACKGROUND To study segmental structural and functional aortic properties in Turner syndrome (TS) patients. Aortic abnormalities contribute to increased morbidity and mortality of women with Turner syndrome. Cardiovascular magnetic resonance (CMR) allows segmental study of aortic elastic properties. METHOD We performed Pulse Wave Velocity (PWV) and distensibility measurements using CMR of the...
متن کاملPravastatin reduces Marfan aortic dilation.
BACKGROUND The sequelae of aortic root dilation are the lethal consequences of Marfan syndrome. The root dilation is attributable to an imbalance between deposition of matrix elements and metalloproteinases in the aortic medial layer as a result of excessive transforming growth factor-beta signaling. This study examined the efficacy and mechanism of statins in attenuating aortic root dilation i...
متن کاملThe bicuspid aortic valve and its relation to aortic dilation
BACKGROUND A bicuspid aortic valve (BAV) is a common congenital heart disease, which affects 1-2% of the population. However, the relationship between BAVs and aortic dilation has not been sufficiently elucidated. METHODS A total of 241 BAV patients who were referred to this hospital for cardiac surgery over a 4.75-year period were included in this study. In addition to the clinical character...
