HEART FAILURE STATUS MONITORING
First Claim
Patent Images
1. An implantable medical apparatus, comprising:
- a heart failure information acquisition circuit configured to collect temperature information and left atrial pressure information to provide data sets for an alarm state, a normal sleep state, and a normal wake state; and
a heart failure indication generator configured to;
determine whether a set of temperature and left atrial pressure information collected by the heart failure information acquisition circuit corresponds to the alarm state,update a heart failure score based on the determination, andgenerate at least one indication of heart failure status if the heart failure score meets at least one threshold.

Abstract
Left atrial pressure and temperature of a patient are monitored to identify a normal wake state, a normal sleep state, and any deviation from those normal states (e.g., an alarm state). In the event an alarm state is identified, a determination is made as to whether to generate an indication of heart failure exacerbation based on a heart failure score. In addition, congestion and perfusion in a patient may be monitored over time to provide a two-dimensional indication of a trend relating to the heart failure status of the patient.
