DEVICE AND METHOD OF MONITORING A PATIENT
First Claim
Patent Images
1. A system for monitoring heart failure in a patient in a home setting, comprising:
- a plurality of sampling devices, wherein each sampling device is configured to obtain a body fluid sample from the patient;
an assay instrument, wherein the assay instrument is configured to determine a series of concentrations of a marker of left ventricular volume overload or myocardial stretch, each concentration in the series determined by introducing a body fluid sample obtained from the patient using one of the sampling devices into the assay instrument which (i) contacts the sample with an antibody under conditions such that immunospecific binding of the marker in the sample to the antibody occurs, and (ii) determines the concentration from the amount of the marker bound by the antibody;
a computer storage medium which receives and stores each concentration in the series;
a computer processor operably connected to the computer storage medium and configured to process the series of concentrations recorded on the computer storage medium by comparing one or more of the concentrations in the series of concentrations to a threshold value determined from the series of concentrations, wherein an excursion indicative of heart failure decompensation is identified by a concentration which is greater than the threshold concentration; and
a display device operably connected to the processor and configured to alert the patient or the patient'"'"'s physician when an excursion indicative of heart failure decompensation is identified by displaying an alert.

Abstract
A device for remote management of patients suffering or likely to suffer from heart failure that can measure the amplitude and frequency changes of one or more biomarkers. The device aids in predicting the need for medical intervention in such patients. The device may further aid in monitoring the efficacy and safety of treatment in such patients.

2. A method of monitoring heart failure patient for potential decompensation, comprising:
-
measuring a series of concentrations of a marker of left ventricular volume overload or myocardial stretch on body fluid samples taken from a patient at a predetermined regular interval in the patient'"'"'s home, each concentration in the series determined by introducing a body fluid sample obtained from the patient into an assay instrument which (i) contacts the sample with an antibody under conditions such that immunospecific binding of the marker in the sample to the antibody occurs, and (ii) determines the concentration from the amount of the marker bound by the antibody; recording each concentration in the series of concentrations on a computer storage medium; processing the series of concentrations recorded on the computer storage medium using a processor operably connected to the computer storage medium by comparing one or more of the concentrations in the series of concentrations to a threshold value determined from the series of concentrations, wherein an excursion indicative of heart failure decompensation is identified by a concentration which is greater than the threshold concentration; and alerting the patient or the patient'"'"'s physician when an excursion indicative of heart failure decompensation is identified by displaying an alert on a display device operably connected to the processor. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
