DETERMINING PROSPECTIVE RISK OF HEART FAILURE HOSPITALIZATION

摘要

A method of operation of a medical device system for determining prospective heart failure hospitalization risk. The method includes measuring one or more data observations via one or more electrodes of an implanted medical device disposed in a patient's body. The data observations are stored into memory of the implantable medical device of a patient. The data observations are transmitted to an external device. The processor of the external device parses the data observations into one or more evaluation periods. Using the number of observations in one or more evaluation periods, a look up table, stored into memory of the external device, is accessed. The look up table associates prospective heart failure hospitalization risk with the data observations noted in the evaluation period. One or more embodiments involve a weighted prospective heart failure hospitalization risk for the set of evaluation periods. The prospective heart failure hospitalization is then displayed on the graphical user interface.

主权项

1. A method of operation of a medical system for determining prospective heart failure hospitalization risk, the method comprising:
(a) acquiring from a device memory a heart failure patient's current and preceding evaluation periods; (b) counting detected data observations in the current evaluation period for a current evaluation total amount and counting detected data observations in the preceding evaluation period for a preceding evaluation period total amount; (c) associating the current evaluation and preceding evaluation total amounts with a lookup table to acquire prospective risk of heart failure hospitalization (HFH) for the preceding evaluation period and the current evaluation period; (d) employing weighted sums of the prospective risk of HFH for the preceding evaluation period and the current evaluation period to calculate a weighted prospective risk of HFH for a patient; and (e) displaying on a graphical user interface the weighted prospective risk of HFH for the patient.
