Table 3. Heart survival after global ischemia.

	6 min, %
Ischemia time	Without FA	With FA	12 min, %
WT	73 (14)	78 (10)	0 (5)
KO	55 (22)*	53 (15)*	0 (5)
GR	80 (10)	80 (8)	0 (5)

Hearts were subjected to the indicated periods of ischemia, and the percentage of hearts that recovered is shown. The hearts were considered failing when they had ventricular arrhythmia (persistent ventricular fibrillations) or absence of aortic flow (against 55 mmHg after load pressure, the left ventricle was incapable of producing any forward pressure). The number of cases is between parentheses. Data are means ± SEM.

^*P < 0.01, WT and GR versus KO.
