Heart failure management

摘要

Various system embodiments comprise a stimulator adapted to deliver a stimulation signal for a heart failure therapy, a number of sensors adapted to provide at least a first measurement of a heart failure status and a second measurement of the heart failure status, and a controller. The controller is connected to the stimulator and to the number of sensors. The controller is adapted to use the first and second measurements to create a heart failure status index, and control the stimulator to modulate the signal using the index. Other aspects and embodiments are provided herein.

1. A system, comprising:
a stimulator configured to deliver a stimulation signal fir a heart failure therapy; and a processor and a non-transitory medium with instructions contained therein for implementation by the processor, the processor configured to operate on the instructions to:
create heart failure status indices using heart failure parameters, the heart failure status indices including a short term heart failure status index for detecting inadequate cardiac output and a long term heart failure status index for detecting worsening or improving heart failure; andcontrol the stimulator to deliver the heart failure therapy using both the short-term heart failure status index and the long-term heart failure index.
