This disclosure is directed to systems and techniques for detecting change in patient health based upon patient data. In one example, a medical system comprising processing circuitry communicably coupled to a glucose sensor and configured to generate continuous glucose sensor measurements of a patient. The processing circuitry is further configured to: extract at least one feature from the continuous glucose sensor measurements over at least one time period, wherein the at least one feature comprises one or more of an amount of time within a pre-determined glucose level range, a number of hypoglycemia events, a number of hyperglycemia events, or one or more statistical metrics corresponding to the continuous glucose sensor measurements; apply a machine learning model to the at least one extracted feature to produce data indicative of a risk of a cardiovascular event; and generate output data based on the risk of the cardiovascular event.

Detection of changes in patient health based on glucose data

An external device transfers a key to an implantable medical device over a proximity communication and then establishes a first far field communication session with the implantable medical device where the key is used for the first communication session. This first communication session may occur before implantation while the implantable medical device is positioned outside of the sterile field so that using a proximity communication is easily achieved. Once the implantable medical device is passed into the sterile field for implantation, the external device may then establish a second far field communication session with the implantable medical device where the last key that was used for the first communication session is again used for the second communication session which avoids the need for another proximity communication to occur within the sterile field.

Methods, devices, and systems for communicating with an implantable medical device of a last far field communication session during a subsequent far field communication session while using a same session key

In some examples, a method including wirelessly communicating, using an external medical device, with an implantable medical device via a telemetry head device, wherein the telemetry head device includes a power source configured to supply operational power to the telemetry head device; determining a first power level of the power source while the external medical device wirelessly communicates with the implantable medical device via the telemetry head device; suspending wireless communication between the implantable medical device and the external medical device based on the determined first power level. The wireless communication may be resumed, e.g., at the point communication was suspended, upon determining that the power level of the power source has been increased after the communication was suspended.
