Hemodynamic Findings in Both Study Groups During Rest, CPT, and Pharmacologic Stress
| Parameter | SLE | Healthy control | P |
| Heart rate (beats/min) | |||
| Rest | 67 ± 11 | 62 ± 6 | 0.68 |
| CPT | 81 ± 20 | 67 ± 8 | 0.01 |
| Stress | 96 ± 13 | 88 ± 11 | 0.06 |
| Systolic blood pressure (mm Hg) | |||
| Rest | 107 ± 9 | 108 ± 13 | 0.74 |
| CPT | 120 ± 8 | 113 ± 9 | 0.03 |
| Stress | 117 ± 9 | 112 ± 10 | 0.17 |
| RPP | |||
| Rest | 7,201 ± 1,434 | 6,628 ± 833 | 0.18 |
| CPT | 9,819 ± 2,584 | 7,583 ± 845 | 0.03 |
| Stress | 11,200 ± 1,911 | 9,729 ± 998 | 0.01 |
| δ-RPP (%) | 37% ± 26% | 16% ± 20% | 0.01 |
δ-RPP = percentage change in RPP between rest and CPT = (RPP CPT – RPP rest)/RPP rest.
Data are mean ± SD.
