This document discusses, among other things, systems and methods to enable physician labels on a remote server and use labels to verify and improve algorithm results. A method comprises using patient data in an automated analysis to obtain a result; receiving a message from the user, wherein the message is related to the result; and using at least a portion of the message to automatically modify the analysis.

This document discusses, among other things, systems and methods for predicting heart failure decompensation using within-patient diagnostics. A method comprises detecting an alert status of each of one or more sensors; calculating an alert score by combining the detected alerts; and calculating a composite alert score, the composite alert score being indicative of a physiological condition and comprising a combination of two or more alert scores.

Within-patient algorithm to predict heart failure decompensation

This document discusses, among other things, a system comprising a sensor signal processor configured to receive a plurality of electrical sensor signals produced by a plurality of sensors and at least one sensor signal produced by an implantable sensor, a memory that includes information indicating a co-morbidity of a subject, a sensor signal selection circuit that selects a sensor signal to monitor from among the plurality of sensor signals, according to an indicated co-morbidity, a threshold adjustment circuit that adjusts a detection threshold of the selected sensor signal according to the indicated co-morbidity, and a decision circuit that applies the adjusted detection threshold to the selected sensor signal to determine whether an event associated with worsening heart failure (HF) occurred in the subject and outputs an indication of whether the event associated with worsening HF occurred to a user or process.

Differentiating decompensation detection based on co-morbidities in heart failure

Various implantable medical device embodiments stimulate an autonomic neural target from within a pulmonary artery, and comprise at least one electrode, a power supply, a neural stimulator connected to the power supply, and an anchor structure. The neural stimulator is configured to generate a neural stimulation signal for delivery to the neural stimulation target through the at least one electrode. The anchor structure is configured to chronically and securely implant the neural stimulator, the power supply and the at least one electrode within the pulmonary artery. The anchor structure, the neural stimulator, the power supply and the at least one electrode are configured to be implanted through a pulmonary valve into the pulmonary artery. In various embodiments, the neural stimulator is configured to be operational to implement a neural stimulation protocol when chronically implanted within the pulmonary artery without a wired connection through the pulmonary valve.

This document discusses, among other things, systems and methods for using one or more inter-relations between within-patient detection methods and between-patient stratifier methods. A method comprises obtaining results of a first physiological assessment, wherein the first physiological assessment includes a between-patient assessment; and using the results to adjust one or more parameters of a second physiological assessment, wherein the second physiological assessment includes a within-patient assessment.

Inter-relation between within-patient decompensation detection algorithm and between-patient stratifier to manage HF patients in a more efficient manner

Embodiments of the invention are related to devices and methods for myocardial ischemia detection, amongst other things. In an embodiment, the invention includes an implantable medical device including control circuitry, an electrical field sensor in communication with the control circuitry, the electrical field sensor configured to generate a signal corresponding to cardiac electrical fields. The implantable medical device can also include a chemical sensor in communication with the control circuitry, the chemical sensor configured to generate a signal corresponding to the concentration of a physiological analyte that affects cardiac electrical field waveform morphology. The control circuitry can be configured to monitor for the presence of myocardial ischemia by evaluating both the signal generated by the electrical field sensor and the signal generated by the chemical sensor. Other embodiments are also included herein.

This document discusses, among other things, systems and methods for using between-patient comparisons for risk stratification of future heart failure decompensation. A method comprises receiving patient data of a current patient, the patient data collected by a patient monitoring device; determining a reference group related to the patient; determining a reference group dataset selected from the reference group, wherein the dataset includes patient data that is of a similar type received from the patient monitoring device; generating a model of the reference group dataset; and automatically comparing the received physiological data to a model to derive an index for the patient.

System for stimulating autonomic targets from pulmonary artery

A method of collecting patient event information from a cardiac rhythm management system (CRM system) is described, where the CRM system includes a cardiac rhythm management device (CRM device) and an external interface device. The method includes the steps of initiating a transmission session wherein the interface device communicates with the CRM device, prompting a user of the CRM system to select a reason for the transmission session, inputting the selected reason for the transmission session to the interface device, and storing the selected reason for the transmission session and timestamp information for the transmission session.
