Table 2. Detailed results for the HUT across orthostatic hypotension categories.
| HUT test results | SOH (n=65) | POH (n=38) | OHPR (n=21) | TOH (n=27) | p |
|---|---|---|---|---|---|
| Early tilting termination | 8 (12.3) | 16 (42.1) | 2 (9.5) | 2 (7.4) | <0.001 |
| Symptom on tilting | 8 (12.3) | 16 (42.1) | 2 (9.5) | 3 (11.1) | 0.001 |
| Systolic BP (mm Hg) | |||||
| Baseline | 138.9±21.1 | 137.7±23.7 | 136.9±16.1 | 130.3±21.1 | 0.357 |
| Lowest BP during HUT | 94.6±20.3a | 81.1±19.6a,b | 93.2±18.3 | 104.1±22.1b | <0.001 |
| Change in systolic BP | 44.3±13.5a,c | 56.6±21.7a,b,c | 43.7±12.0b,c | 26.2±5.1c | <0.001 |
Data are n (%) or mean±SD values. Means with the same letter differed significantly in Tukey's honest-significant-difference test.
BP: blood pressure, HUT: head-up tilt, OHPR: orthostatic hypotension with partial recovery, POH: progressive orthostatic hypotension, SOH: sustained orthostatic hypotension, TOH: transient orthostatic hypotension.
