1. A method for controlling a cardiac support system, the method comprising:
determining, using a first sensor signal at a first time from a first sensor of the cardiac support system, a first operating state, wherein the first operating state is associated with an impeller of the cardiac support system implanted into a heart;
receiving a second sensor signal at a second time from a second sensor of the cardiac support system, the second sensor signal associated with a second operating state of a component of the cardiac support system;
determining a wear signal based at least in part on the first sensor signal, the second sensor signal, and a comparison rule, wherein the wear signal is associated with the state of wear of the component of the cardiac support system; and
controlling the component of the cardiac support system associated with the second sensor signal with a control signal based on the wear signal.
