Clinical Study

Table 1
The background data of the 123 subjects collected at the 1st and the 2nd followup of the cohort.
| | Age 68 years | Age 81 years |
| In whole cohort: | n = 123 | n = 123 | carotid stenosis right <50%, n (%) | | 116 (94.3) | carotid stenosis left <50%, n (%) | | 110 (89.4) | right ICA’s PSV (m/s); min–max; mean (SD) | | .3–3.0; .76 (4.1) | left ICA’s PSV (m/s); min–max; mean (SD) | | .4–4.0; .82 (.47) |
| In subjects with right carotid stenosis <50%: | | n = 116 | right ICA’s PSV (m/s); min–max; mean (SD) | | .3–1.2; .67 (.17) | frequency of stenosis: 0%–35%–40%; n subjects | | 22–91–3 |
| In subjects with left carotid stenosis <50%: | | n = 110 | Left ICA’s PSV (m/s); min-max; mean (SD) | | .4–1.3; .69 (.17) | Frequency of stenosis: 0%–35%–40%–45%; n subjects | | 21–85–2–2 |
| In subjects with carotid stenosis <50%, left or right: | n = 107 | n = 107 | SBP, mmHg (SD) | 150.6 (19.0) | 143.4 (15.3) | DBP, mmHg (SD) | 92.1 (7.9) | 82.5 (6.4) | pulse pressure, mmHg (SD) | 58.1 (14.8) | 60.1 (14.1) | Ankle brachial index: | | | Right | 1.13 (.12) | 1.03 (.19) | Left | 1.09 (.12) | 1.00 (.19) | Difference ABI ages 81–68, right | | −.10 (.17) | Difference ABI ages 81–68, left | | −.09 (.15) |
