Perfusion parameters from the dual-intensity protocol
| Elderly Healthy Subjects | Patients With PAD | |||
|---|---|---|---|---|
| “Low intensity” | “Exhaustion” 14.0 (3.5) lb | “Low intensity” | “Exhaustion” 14.2 (5.5) lb | |
| G, ml·min−1·100 g−1 | 106.7 (73.2) | 135.0 (52.9) | 43.4 (23.5) | 81.8 (60.9) |
| S, ml·min−1·100 g−1 | 36.1 (23.3) | 66.9 (31.0) | 27.6 (12.2) | 87.0 (64.0) |
| G/WBP | 4.0 (2.6) | 5.0 (1.6) | 2.3 (2.2) | 3.5 (3.1) |
| S/WBP | 1.4 (1.0) | 2.6 (1.5) | 1.2 (0.8) | 3.6 (2.6) |
| G/S | 3.1 (1.0) | 2.7 (2.1) | 1.9 (1.3) | 1.0 (0.4) |
Values are means (SD); n = 5. G, gastrocnemius perfusion; S, soleus perfusion; WBP, whole body perfusion (equal to cardiac output divided by body weight); PAD, peripheral artery disease.
