Overall, the positive effect of the hot shot interval on recovery of the macroergic phosphates is almost completely lost in the subsequent KH perfusion interval. The apparently contradictory functional recovery of these hearts remained significantly improved. During the cardioplegic hot shot, the temporary high energy phosphate recovery must be closely related to the very low energy demand of the arrested myocardium. In the ensuing KH reperfusion interval, the high energy requirement of the beating heart causes a gradual loss of the apparent improvement in the recovery of macroergic phosphates. As discussed in the case of the beating heart groups, the final myocardium recovery probably reflects the slow recovery in creatine kinase activity .
In conclusion, the introduction of a short cardioplegic hot shot at the start of the postischemic reperfusion is beneficial to the rat heart. The hot shot protective effect can be achieved within 10 mins of hot shot perfusion. Resuscitation of the rat heart by WBCP is comparable with that by standard warm crystalloid cardioplegic solutions. The advantage of WBCP is that it can be applied at a much reduced flow rate and volumes throughout.
