Table 3:
Hemodynamic differences at baseline between groups with higher vs. lower rates of AAo dilation (n=72).
| GR mean AAo > 0.24 mm/year (n=32) | GR mean AAo < 0.24mm/year (n=40) | p | |
|---|---|---|---|
| AAo Vmax (m.s−1) | 1.74 [1.48- 2.07] | 1.48 [1.37- 1.79] | 0.030 |
| AAo Mean WSS (Pa) | 0.76 [0.67- 0.93] | 0.66 [0.62- 0.82] | 0.058 |
| AAo Max WSS (Pa) | 1.59[1.37- 2.01] | 1.38 [1.21- 1.74] | 0.055 |
| AAo relative area of elevated WSS (%) | 19.9 [10.2- 25.5] | 5.7 [1.5- 21.3] | 0.008 |
| Entire aorta relative area of elevated WSS (%) | 9.1 [4.8- 14.4] | 3.4 [1.2 −9.7] | 0.009 |
AAo: Ascending Aorta; GR: growth rate, Vmax: maximum velocity, WSS: wall shear stress
