Abstract

One or more example techniques for monitoring the stroke risk of a patient via a system including an implantable medical device. In some examples, a method including monitoring at least one physiological parameter of a patient via an implantable medical device; determining whether each of a plurality stroke risk factors are present based at least in part on the at least one physiological parameters monitored via the implantable medical device; and generating a stroke risk score based on the stroke risk factors determined to be present, wherein the stroke risk score is reflective of the patient'"'"'s risk of stroke.

Claims

1. A method comprising:

monitoring at least one physiological parameter of a patient via an implantable medical device;

determining whether each of a plurality stroke risk factors are present based at least in part on the at least one physiological parameters monitored via the implantable medical device; and

generating a stroke risk score based on the stroke risk factors determined to be present, wherein the stroke risk score is reflective of the patient'"'"'s risk of stroke.

2. The method of claim 1, wherein the plurality of stroke risk factors include one or more of atrial fibrillation, hypertension, congestive heart failure, patient age above threshold, diabetes, prior stroke and prior transient ischemic attack.

3. The method of claim 1, further comprising:

comparing the stroke risk score to a threshold value; and

generating an indicator indicative of the stroke risk score based on the comparison.

4. The method of claim 3, further comprising presenting the indicator to a user via a user interface.

5. The method of claim 1, further comprising adjusting the delivery of electrical stimulation therapy to the patient based at least in part on the stroke risk score.

6. The method of claim 1, wherein the implantable medical device comprises an implantable cardiac device configured to deliver electrical stimulation to a heart of the patient.

7. The method of claim 1, wherein the one or more physiological parameters includes at least one of electrical activity of a heart of the patient, blood pressure of the patient, blood flow of the patient, blood sugar level of the patient, and intrathoracic impedance of the patient.

8. The method of claim 1, wherein the stroke risk score comprises a numerical value.

9. The method of claim 8, wherein the plurality of stroke risk factors are each associated with a stroke risk value used to generate the stroke risk score.

10. The method of claim 1, further comprising detecting the presence of atrial fibrillation, wherein the stroke risk score is generated based on both the stroke risk factors determined to be present and detecting the presence of atrial fibrillation.

11. The method of claim 1, wherein the stroke risk score is based on the presence of the two or more stroke risk factors.

12. A stroke risk monitoring system comprising:

an implantable medical device including a sensing module configured to monitor at least one physiological parameter of a patient; and

a processor configured to determine whether each of a plurality of stroke risk factors are present based at least in part the at least one physiological parameter, and generate a stroke risk score based on the stroke risk factors determined to be present,

wherein the stroke risk score is reflective of the patient'"'"'s risk of stroke.

13. The system of claim 12, wherein the plurality of stroke risk factors include one or more of atrial fibrillation, hypertension, congestive heart failure, patient age above threshold, diabetes, prior stroke and prior transient ischemic attack.

14. The system of claim 12, wherein the processor is configured to compare the stroke risk score to a threshold value;
