System and method for evaluating a patient status for use in heart failure assessment
First Claim
1. A system for evaluating a patient status for use in heart failure assessment, comprising:
- a data module to assemble physiological measures of a patient and of one or more of the group consisting of;
a peer group of disease-specific patients, and an overall patient population, wherein each physiological measure was directly recorded as data on a substantially continuous basis by an implantable medical device for a particular patient or indirectly derived from the data;
a status module to determine wellness indicators for the patient through sampling and analysis of the physiological measures over a plurality of data assembly points; and
an evaluation module to evaluate the physiological measures, comprising;
an analysis module to identify a patient status that is indicated by a trend in the wellness indicators; and
a comparison module to compare the patient status to worsening heart failure indications.

Abstract
A system and method for evaluating a patient status from sampled physiometry for use in heart failure assessment is provided. Physiological measures are stored, including at least one of direct measures regularly recorded on a substantially continuous basis by an implantable medical device for a patient and measures derived from the direct measures. At least one of those of the physiological measures, which each relate to a same type of physiometry, and those of the physiological measures, which each relate to a different type of physiometry are sampled. A status for the patient is determined through analysis of the sampled physiological measures assembled from a plurality of recordation points. The sampled physiological measures are evaluated. Trends that are indicated by the patient status, which might affect cardiac performance of the patient, are identified. Each trend is compared to worsening heart failure indications to generate a notification of parameter violations.
