In vitro left ventricular function data.
| Variables | SHAM (n = 5) | Myocardial infarction (n = 5) | p-value |
| + dP/dt max, (mmHg/s) | 4375±843 | 2675±813.0 | 0.012 |
| - dP/dt max, (mmHg/s) | 2125 (1969-2500) | 1750.0 (1219-1750) | 0.008 |
SHAM: rats subjected to surgery but without coronary occlusion; +dP/dt max: maximum rate of ventricular pressure rise; -dP/dt max: maximum rate of ventricular pressure decrease. Data are expressed as means±SD or medians (25%-75%).
