1. A computer-implemented system for evaluating a patient status for use in heart failure assessment, comprising: a data module configured to assemble physiological measures which were electronically stored in a memory and directly recorded as data on a substantially continuous basis by medical device for a patient or indirectly derived from the data, wherein the physiological measures comprise measures for the patient and one or more of measures for a peer group of disease specific patients and measures for an overall patient population; a status module configured to sample the physiological measures over a plurality of data assembly points; an evaluation module configured to evaluate and match at each data assembly point the sampled physiological measures to determine a patient status indicator; a diagnosis module configured to determine one of a status quo and a change in cardiac performance of the patient and compare the change in the cardiac performance to worsening heart failure indications; a quality of life module configured to query the patient on a regular basis and collect quality of life measures and to chronicle the quality of life measures with the physiological measures; and a feedback module configured to provide tiered feedback based on the patient status indicator comprising: a first level module configured to communicate, at a first level, an interpretation of the change in the cardiac performance; a second level module configured to communicate, at a second level, a notification of potential medical concern based on the change in the cardiac performance to the patient; a third level module configured to communicate, at a third level, a notification of potential medical concern based on the change in the cardiac performance to medical personnel; and a fourth level module configured to communicate to a patient medical device of the patient, at a fourth level, a set of reprogramming instructions based on the change in the cardiac performance; wherein the tiered feedback has increasing levels of patient involvement and medical care intervention.
