Exercise Stress Test
| Surgery (n=28) | Balloon Dilation (n=23) | Stent (n=24) | P Value | |
|---|---|---|---|---|
| Exercise duration, min | 12 (7, 21) | 11 (9, 21) | 13 (5, 17) | 0.45 |
| Pre‐exercise SBP gradient, mm Hg | −3±21 | 1±9 | 6±18 | 0.17 |
| Peak‐exercise SBP gradient, mm Hg | 32±30 | 33±22 | 26±27 | 0.64 |
| Peak right arm SBP, mm Hg | 177±35 | 157±27 | 177±33 | 0.05 |
| Peak right arm DBP, mm Hg | 71±13 | 75±9 | 73±11 | 0.50 |
| VO2 max, mL/kg/min | 41±11 | 32±27 | 41±11 | 0.30 |
| VE/CO2 slope | 26±4 | 26±5 | 26±6 | 0.98 |
Values are mean±SD, or median (minimum, maximum). DBP indicates diastolic blood pressure; SBP, systolic blood pressure; VE/CO2, relationship between ventilation and CO2 output; VO2 max, peak exercise oxygen consumption.
