Use of antihypertensive drugs in the study hypertensive patients who were grouped according to the median value of the Augmentation Index (AIx) and carotid-femoral pulse wave velocity (cfPWV).
| Variables | All patients (n = 128) | AIx ≤median (n = 55) | AIx >median (n = 73) | p value | cfPWV ≤median (n = 64) | cfPWV >median (n = 64) | p value |
|---|---|---|---|---|---|---|---|
| Antihypertensive drugs, n (%) | 81 (63) | 30 (54) | 51 (70) | 0.075 | 33 (52) | 48 (75) | 0.006 |
| Renin-angiotensin system blockers, n (%) | 48 (37) | 17 (31) | 31 (45) | 0.181 | 18 (28) | 30 (47) | 0.028 |
| Calcium-channel blockers, n (%) | 44 (34) | 19 (34) | 17 (34) | 0.972 | 16 (25) | 28 (44) | 0.026 |
| Diuretics, n (%) | 35 (27) | 12 (22) | 23 (32) | 0.223 | 16 (25) | 19 (30) | 0.552 |
| Beta blockers, n (%) | 30 (23) | 10 (18) | 20 (27) | 0.223 | 12 (19) | 18 (28) | 0.211 |

Values are expressed as absolute numbers and percentages. The Pearson’s Chi-square test was used to compare frequency distributions. Reported p values for the comparison between patients with an Augmentation Index or carotid-femoral pulse wave velocity above or below the median value of the distribution (respectively: 28 and 7.6 m/s).
