1. A medical device, comprising:

  • a signal analyzer circuit, including;

    a patient status input unit configured to receive at least a first demographic characteristic indicator and a second demographic characteristic indicator of a patient, the second demographic characteristic indicator non-identical to the first demographic characteristic indicator;

    a signal receiver circuit configured to receive one or more physiologic signals of the patient;

    a signal metrics generator circuit configured to generate a plurality of signal metrics from the one or more physiologic signals, including to generate a first set of one or more signal metrics in response to the first demographic characteristic indicator meeting at least one first specified criterion, and to generate a second set of signal metrics in response to the second demographic characteristic indicator meeting at least one second specified criterion; and

    a patient-specific signal metric selector circuit configured to select a subset of patient-specific signal metrics from the first and second sets of signal metrics using signal metric performance measures of at least one metric from the first and second sets of signal metrics; and

    a risk stratification circuit configured to generate a composite risk index using the selected subset of patient-specific signal metrics, the composite risk index indicative of the probability of the patient later developing an event indicative of worsening of heart failure, the risk stratification circuit comprising a risk report generator configured to generate a report to inform a user of an elevated risk of the patient developing the event indicative of worsening of heart failure.
