Invasive hemodynamic measurements of control and nitrate-supplemented rats
| Control | Nitrate | P | |
|---|---|---|---|
| Heart rate, beats/min | 328 | 332 | 0.44 |
| dP/dtLVP40, mmHg/s | 6,024 | 6,064 | 0.98 |
| τ, ms | 10.74 | 10.63 | 0.71 |
| Mean arterial pressure, mmHg | 112 | 102 | <0.0001 |
| Systolic BP, mmHg | 121 | 113 | <0.001 |
| Diastolic BP, mmHg | 96 | 92 | 0.05 |
Values are means ± SE; n = 8–11 rats/group. dP/dtLVP40, rate of pressure development during isovolumic LV contraction; BP blood pressure; τ, time constant of isovolumic LV relaxation (Weiss method).
