Table 2. Ankle-brachial index (ABI), brachial-ankle pulse wave velocity (baPWV) and arterial volume distensibility from the normal subjects and BRVO patients.
| Variables | Normal subjects | BRVO patients | P-value after adjusting for pulse pressure |
|---|---|---|---|
| Left side ABI | 1.11 ± 0.09 | 1.12 ± 0.12 | NS |
| Right side ABI | 1.13 ± 0.09 | 1.12 ± 0.12 | NS |
| Average ABI | 1.12 ± 0.09 | 1.12 ± 0.12 | NS |
| Left side baPWV (m/s) | 12.7 ± 0.9 | 15.7 ± 2.6 | <0.01 |
| Right side baPWV (m/s) | 12.8 ± 1.0 | 16.0 ± 3.0 | <0.01 |
| Average baPWV (m/s) | 12.7 ± 0.9 | 15.8 ± 2.6 | <0.01 |
| Left side distensibility (% per mmHg) | 0.06 ± 0.01 | 0.04 ± 0.02 | <0.01 |
| Right side distensibility (% per mmHg) | 0.06 ± 0.01 | 0.04 ± 0.02 | <0.01 |
| Average distensibility (% per mmHg) | 0.06 ± 0.01 | 0.04 ± 0.02 | <0.01 |
Data are expressed as mean ± SD. NS: no significant difference, ABI: ankle brachial index, PWV: pulse wave velocity.
