An implantable medical device for monitoring tissue perfusion that includes a light source emitting light having a light wavelength corresponding to a blue to ultraviolet light spectrum and a light detector receiving light emitted by the light source and scattered by a volume of body tissue. The light detector emits a signal correlated to the received light wavelength, and a processor receives the signal from the light detector and determines a patient condition in response to the signal.
