Haemodynamic and morphological data from control and heart failure (HF) rats
| Control (n = 6) | HF (n = 6) | |||
|---|---|---|---|---|
| BW (g) | 494 | ±26 | 495 | ±15 |
| HW (g) | 1.30 | ±0.05 | 1.68 | ±0.12* |
| CWI (mg g−1) | 2.65 | ±0.1 | 3.23 | ±0.15* |
| Infarct size (%LV) | — | — | 46 | ±3 |
| LVEDP (mmHg) | 8 | ±1 | 17 | ±1* |
| +dP/dt (mmHg s−1) | 10,182 | ±284 | 6790 | ±338* |
| −dP/dt (mmHg s−1) | −10,363 | ±825 | −6470 | ±617 |
| MAP (mmHg) | 103 | ±2 | 107 | ±2 |
| HR (beats min−1) | 376 | ±15 | 395 | ±19 |
Data are means ± SEM. BW: body weight; HW: heart weight; CWI: cardiac weight index; LVEDP: left ventricle end‐diastolic pressure; +dP/dt and −dP/dt: maximal slope of the systolic increment and diastolic decrement of ventricular pressure, respectively; MAP: mean arterial pressure; HR: heart rate. * P < 0.05 compared to control group.
