| LVDP, mmHg | 148 ± 8 | 144 ± 11 | 139 ± 9 | 146 ± 5 | 138 ± 7 | NS |
| Heart rate, beats/min | 266 ± 10 | 269 ± 8 | 273 ± 11 | 273 ± 9 | 279 ± 7 | NS |
| RPP, mmHg/min | 39,110 ± 3,077 | 38,518 ± 3,529 | 37,832 ± 1,964 | 39,624 ± 2,190 | 38,432 ± 1,356 | NS |
| CF, ml · min−1 · g wet wt−1 | 9.7 ± 0.5 | 10.4 ± 0.4 | 9.6 ± 0.1 | 9.8 ± 0.3 | 10.5 ± 0.4 | NS |
Values are means ± SE. The number of experiments was 10 per group: C, control group; L, lactate group; G, glucose-insulin-potassium (GIK) group; P, pyruvate group; PE, pyruvate + ethanol group. LVDP, left ventricular developed pressure; heart rate; RPP, rate-pressure product; CF, coronary flow; ANOVA, analysis of variance; NS, not significant.
