Abstract

An embodiment of a device for reporting a heart failure status of a patient comprises: a parameter acquisition module configured to acquire at least one trended heart failure parameter; a predetermined event acquisition module configured to acquire at least one predetermined event corresponding to the at least one trended heart failure parameter, wherein each of the at least one predetermined event represents an event condition where a predetermined event definition is satisfied; an alert acquisition module configured to acquire at least one heart failure status alert associated with the at least one predetermined event, wherein each of the at least one alert represents an alert condition where a predetermined alert definition is satisfied; and an output communication module configured to communicate the at least one heart failure status alert.

First claim

What is claimed is:

1. A programmable device, comprising processing circuitry configured to operate on instructions stored in a memory to perform a process to report a heart failure status of a patient, the process comprising:
acquiring one or more trended heart failure parameters;
acquiring one or more predetermined events corresponding to the one or more trended heart failure parameters, wherein each of the one or more predetermined events represents an event condition where a predetermined event definition is satisfied;
acquiring one or more heart failure status alerts associated with the one or more predetermined events, wherein each of the one or more heart failure status alerts represents an alert condition where a predetermined alert definition is satisfied, and is distinct from each of the one or more events; and
communicating the one or more heart failure status alerts, wherein the one or more trended heart failure parameters includes at least one of the group consisting of: a trended tidal volume to respiration rate parameter, a trended heart rate to minute ventilation parameter, a trended heart rate to work rate parameter, a ventilatory response to work rate parameter, trended percent AF, trended LV end diastolic pressure, trended body weight, trended orthopnea, trended peripheral edema, trended pulmonary edema, and trended heart sounds.

2. The device of claim 1 , wherein the computer-executable process further comprises detecting the one or more predetermined events using the one or more trended heart failure parameters and generating the one or more heart failure status alerts associated with the one or more predetermined events.

3. The device of claim 1 , wherein the computer executable process further comprises communicating the one or more trended heart failure parameters or the one or more predetermined events in a manner suitable for use in determining the heart failure status of the patient.

4. The device of claim 1 , further comprising a display with a display area, wherein:
the computer-executable process further comprises detecting the one or more predetermined events using the one or more trended heart failure parameters and generating the one or more heart failure status alerts associated with the one or more predetermined events;
communicating the one or more trended heart failure parameters or the one or more predetermined events in a manner suitable for use in determining the heart failure status of the patient; and
displaying in the display area the one or more heart failure status alerts and at least one of the one or more trended heart failure parameters or the one or more predetermined events.

5. The device of claim 1 , wherein the device includes a programmable implantable medical device (IMD) adapted to acquire the at least one heart failure parameter and adapted to communicate with a programmer adapted to display the one or more heart failure alerts.

6. The device of claim 1 , wherein the device includes a wellness management device (WMD) adapted to display the one or more heart status alerts in a manner suitable for viewing by a clinician or in a manner suitable for viewing by the patient.

7. The device of claim 1 , further comprising a display with a display area, wherein the computer-executable process further comprises filtering the one or more trended heart failure parameters, the one or more predetermined events, and the one or more heart failure status alerts according to relevance to identify a relevant one or more trended heart failure parameters, a relevant one or more predetermined events, and a relevant one or more alerts, and comprises displaying the relevant one or more trended heart failure parameters, the relevant one or more predetermined events, or the relevant one or more heart failure status alerts in the display area.

8. The device of claim 1 , wherein communicating the one or more heart failure status alerts in a manner suitable for use in determining the heart failure status of the patient includes automatically displaying a report, automatically triggering an alarm, automatically sending an e-mail, automatically sending a telefax, or automatically placing a telephone call.

9. The device of claim 1 , wherein the one or more trended heart failure parameters include trended respiration rate, trended respiration tidal volume, trended activity, trended posture, trended dyspnea, or trended heart rate.

10. The device of claim 1 , wherein the one or more trended heart failure parameters includes a trended tidal volume to respiration rate parameter, a trended heart rate to minute ventilation parameter, a trended heart rate to work rate parameter, or a ventilatory response to work rate parameter.

11. The device of claim 1 , wherein the one or more trended heart failure parameters includes trended percent AF, trended body weight, or trended LV end diastolic pressure.

12. The device of claim 1 , wherein the one or more trended heart failure parameters includes trended body weight, trended orthopnea, trended peripheral edema, trended pulmonary edema, or trended heart sounds.

13. The device of claim 1 , wherein the event condition is where a predetermined event definition is satisfied for apnea, activity, respiration rate, posture, percent AF, or weight.

14. The device of claim 1 , wherein the predetermined event definition includes a comparison of present values to previous values for the trended heart failure parameters.

15. The device of claim 1 , wherein the one or more heart failure status alerts includes an alert of worsened heart failure, an alert of worsening heart failure, an alert of future worsening heart failure, or an alert of acute heart failure decompensation.

16. The device of claim 1 , wherein at least one of the predetermined event definition and predetermined alert definition includes a weighted probability.

17. A device for reporting a heart failure status of a patient, comprising:
a parameter acquisition module configured to acquire at least one trended heart failure parameter;
a predetermined event acquisition module configured to acquire at least one predetermined event corresponding to the at least one trended heart failure parameter, wherein each of the at least one predetermined event represents an event condition where a predetermined event definition is satisfied;
an alert acquisition module configured to acquire at least one heart failure status alert associated with the at least one predetermined event, wherein each of the at least one alert represents an alert condition where a predetermined alert definition is satisfied;
an output communication module configured to communicate the at least one heart failure status alert; and
a filter module adapted to communicate with the output communication module and to prioritize the at least one trended heart failure parameter, the at least one predetermined event, and the at least one heart failure status alert according to relevance such that the output communication module communicates higher priority parameters, events or alerts in a preferred manner over lower priority parameters, events or alerts.

18. The device of claim 17 , wherein the device is configured to detect the at least one predetermined event using the one or more trended heart failure parameters and generate the at least one heart failure status alert associated with the one or more predetermined events.

19. The device of claim 17 , wherein the output communication module is further configured to communicate the at least one trended heart failure parameter
