US 2017/0290551 A1 · RENAL DYSFUNCTION RISK STRATIFICATION

Abstract

Systems and methods for assessing a patient's risk of renal dysfunction are described. A system may include sensor circuits to sense physiological signals and processors to generate signal metrics from the physiological signals. The system may generate a primary renal risk indication using a first signal metric, and a secondary renal risk indication using at least a second signal metric. The system may generate a composite renal risk indication and estimate a glomerular filtration rate or a chronic kidney disease stage using at least the primary and secondary risk indications. The composite renal risk indication, which indicative of a degree of renal dysfunction, may be presented to a clinician, or provided to a detector for detecting worsening heart failure.

Dependent claims

A system for identifying a patient's risk of renal dysfunction, the system comprising:

sensor circuits including sense amplifier circuits to sense at least first and second physiological signals;
a signal processor circuit configured to generate a first signal metric from the first physiological signal and a second signal metric from the second physiological signal;
a risk stratifier circuit coupled to the signal processor circuit, the risk stratifier circuit configured to:
generate a primary renal risk indication using at least the first signal metric and a secondary renal risk indication using at least the second signal metric;
and
generate a composite renal risk indication indicative of a degree of renal dysfunction using both the primary and secondary renal risk indications;
and
an output circuit configured to present the composite renal risk indication to a user or a process.
