Abstract

A system and method for evaluating a patient status from sampled physiometry for use in heart failure assessment is presented. Physiological measures are stored, including at least one of direct measures regularly recorded on a substantially continuous basis by an implantable medical device for a patient and measures derived from the direct measures. At least one of those of the physiological measures, which each relate to a same type of physiometry, and those of the physiological measures, which each relate to a different type of physiometry are sampled. A status for the patient is determined through analysis of the sampled physiological measures assembled from a plurality of recordation points. The sampled physiological measures are evaluated. Trends that are indicated by the patient status, which might affect cardiac performance of the patient, are identified. Each trend is compared to worsening heart failure indications to generate a notification of parameter violations.

Claims

1-26. -26. (canceled)

27. A system for evaluating a patient status for use in heart failure assessment, comprising:

an implantable medical device configured to collect patient data on a long-term, daily basis, wherein the implantable medical device is further configured to periodically store battery status data and a collected measures set containing the patient data, wherein the patient data comprises at least atrial electrical activity;

an analysis module configured to receive the collected measures set and compare the collected measures set to comparison data to generate a patient status indicator;

a feedback module to provide notification of the battery status and a potential medical concern based on the patient status indicator; and

a remote database server accessible to patient medical providers that is configured to receive the collected measures set, the battery status, and the notification from the feedback module.

28. The system of claim 27, wherein the comparison data comprises averaged measures.

29. The system of claim 27, further comprising a collection client and a network server, wherein the collection client is configured to be communicatively interposed between the implantable medical device and a communication link, retrieve the collected measures set from the implantable medical device, and download the collected measures set into the network server over the communications link.

30. The system of claim 29, wherein the collection client is selected from the group consisting of:

a programmer, interrogator, recorder, monitor, telemetered signals transceiver, personal computer, digital data processor, and combinations thereof.

31. The system of claim 27, wherein the implantable medical device is further configured to provide cardiac pacing and defibrillation.

32. The system of claim 31, wherein the patient data further comprises the number of device interventions made and the type of device interventions made.

33. The system of claim 32, wherein the patient data further comprises the relative success of any interventions made.

34. The system of claim 27, further comprising a programmer configured to retrieve and display patient data from the implantable medical device.

35. The system of claim 27, wherein the feedback module is further configured to provide the notification consistent with a particular level of patient involvement and medical care intervention from a plurality of levels of patient involvement and medical care intervention.

36. The system of claim 27, wherein the analysis module is configured to dynamically analyze the patient data to generate the patient status indicator.

37. A method for evaluating a patient status for use in heart failure assessment, comprising:

collecting patient data, by an implantable medical device, on a long-term, daily basis, and periodically storing battery status data and a collected measures set containing the patient data, wherein the patient data comprises at least atrial electrical activity;

receiving, by an analysis module, the collected measures set and generating a patient status indicator by comparing the collected measures set to comparison data;

providing notification, by a feedback module, of the battery status and a potential medical concern based on the patient status indicator; and

receiving the collected measures set, the battery status, and the notification, by a remote database server available to patient medical providers.

38. The system of claim 37, wherein the comparison data in the second collected measures set comprises averaged measures.

39. The method of claim 37, further comprising retrieving, by a collection client, the collected measures set from the implantable medical device and downloading the collected measures set into a network server over a communications link.

40. The method of claim 39, wherein the collection client is selected from the group consisting of:

a programmer, interrogator, recorder, monitor, telemetered signals transceiver, personal computer, digital data processor, and combinations thereof.

41. The method of claim 37, providing cardiac pacing and defibrillation by the implantable medical device.

42. The method of claim 41, wherein the patient data comprises the number of device interventions made and the type of device interventions made.

43. The method of claim 42, wherein the patient data further comprises the relative success of any interventions made.

44. The method of claim 37, further comprising retrieving and displaying patient data from the implantable medical device by a programmer.

45. The method of claim 37, wherein providing the notification is consistent with a particular level of patient involvement and medical care intervention from a plurality of levels of patient involvement and medical care intervention.

46. The method of claim 37, wherein generating a patient status indicator by the analysis module comprises dynamically analyzing the patient data.
