Key result
Hypertension was associated with significantly higher mean abdominal aortic stiffness assessed by MR elastography compared to normotension (9.3 ± 1.9 kPa vs 3.7 ± 0.8 kPa; p=0.02).
Why the study?
Can MR elastography (MRE) identify differences in abdominal aortic stiffness between hypertensive and normotensive individuals?
Population
8 volunteers (4 normotensives and 4 controlled-hypertensives)
Comparison

Design
Cross-sectional

MRE may detect elevated aortic stiffness in hypertension; leaves open its prognostic or monitoring utility pending prospective studies.
Cross-Sectional (n=8)
Can MR elastography (MRE) identify differences in abdominal aortic stiffness between hypertensive and normotensive individuals?
Absolute Event Rate: 9.3% vs 3.7%
p-value: p=0.02
MR elastography is a feasible non-invasive method to measure in vivo abdominal aortic stiffness, which is significantly elevated in hypertensive patients.
Kolipaka et al. (2011) conducted a cross-sectional in Hypertension (n=8). Hypertension vs. Normotension was evaluated on Mean abdominal aortic stiffness (kPa) (p=0.02). Hypertension was associated with significantly higher mean abdominal aortic stiffness assessed by MR elastography compared to normotension (9.3 ± 1.9 kPa vs 3.7 ± 0.8 kPa; p=0.02).
