20220096020 | PREDICTION OF HEART FAILURE STATUS - Systems and methods for monitoring a heart failure (HF) patient and forecasting the patient's future HF status are discussed. A system includes a HF predictor circuit to generate a monitored sensor trend using sensor data collected up to a prediction time from the patient. The HF predictor circuit can generate a projected sensor trend for the patient over a forecast period of time in future beyond the prediction time using the monitored sensor trend of the patient and sensor trends collected from a plurality of patients. The projection can be based on a non-parametric predictor or a parametric model. A trajectory of the projected sensor trend may be displayed as a visual forecast of the patient's HF status. | 2022-03-31 |
