The effects of gradually restoring calcium concentration in initiating reperfusion on cardiac function, coronary blood flow and myocardial calcium content during reperfusion following global ischemia have been observed in isolated working rat hearts. The results showed that gradually restoring calcium reperfusion facilitated the recovery of the contracting relaxing and pump functions as well as coronary blood flow, and decreased the occurrence of arrhythmias during reperfusion and myocardial calcium content after reperfusion. The mechanism of the protective effect of gradual calcium restoration on the hearts was probably due to the inhibition of calcium overload in cardiac cells. However high calcium reperfusion deteriorated cardiac function.
