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, which were directly recorded as data on a substantially continuous basis by a medical device for a patient or indirectly derived from the data;
a status module to determine a status for the patient through sampling and analysis of the physiological measures over a plurality of data assembly points; and
an evaluation module to evaluating the physiological measures relative to the patient status, comprising;
an analysis module to analyze any trend comprising one of a status quo and a change in cardiac performance; and
a comparison module to compare the trend 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 presented. Physiological measures, including at least one of direct measures regularly recorded on a substantially continuous basis by a medical device and measures derived from the direct measures are stored. At least one of those of the physiological measures, which relate to a same type of physiometry, and those of the physiological measures, which relate to a different type of physiometry are sampled. A status is determined for a patient through analysis of those sampled measures assembled from a plurality of recordation points. The sampled measures are evaluated. Trends that are indicated by the patient status, including one of a status quo and a change, 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.
