1. A system for managing patient therapy, the system comprising:
(a) an implantable medical device comprising one or more electrodes configured to be implanted within a patient's body, to acquire first signals corresponding to one or more physiological signals sensed from within the patient's body, and to generate first data transmissions in response to the acquired first signals;
(b) a wearable device comprising one or more electrodes configured to be positioned in contact with an external surface of the patient's body, to acquire second signals corresponding to at least one of the one or more physiological signals sensed from the external surface of the patient's body, and to generate second data transmissions in response to the acquired second signals;
(c) an input/output device to receive the first data transmissions and the second data transmissions; and
(d) one or more processors configured to:
(i) receive the first data transmissions and the second data transmissions,
(ii) calculate a heart failure risk score based on comparing the received first data transmissions and the received second data transmissions to one or more thresholds, and weighting the first data transmissions differently than the second data transmissions,
(iii) determine whether data of the received first data transmissions and the received second data transmissions is indicative of a heart failure worsening episode based on the heart failure risk score, and
(iv) display one of an indication of the heart failure worsening episode or the heart failure risk score on a graphical user interface of a computing device in response to the heart failure worsening episode being detected.
