Research Abstract

We have been developed Native Heart Load Control System(NHLCS) through this project, which can control the load on the native heart by controlling the pump drive state in synchronization with the heartbeat. This system was confirmed that it is possible to drive to follow suit to arrhythmia and heart rate changes on the acute animal experiments. Moreover, this system was confirmed to be effective on the chronic heart failure animal model. In addition, it was also been found that may increase coronary blood flow in this drive system, which is also expected to be a novel ischemic heart failure treatment. And it also may increase pulsatile arterial pressure in systemic blood flow by driving the system. Currently, including the additive effect of these various, mounted to the actual future artificial heart has been expected.
