1. A system comprising:

  • a heart failure event detection circuit, configured to analyze information from different physiological signals to determine a heart failure event indication corresponding to a time period;

    a non-heart failure physiological event detection circuit, configured to determine a non-heart failure physiological event characteristic including detecting a heart failure co-morbidity different than an improvement or worsening of the heart failure event using at least one of the different physiological signals;

    a comparison circuit, configured to compare the at least one of the different physiological signals to a specified criterion indicative of the heart failure event to provide a comparison value indicating whether the non-heart failure physiological event characteristic contributes to the heart failure event indication; and

    a non-heart failure status indicator circuit, coupled to the heart failure event detection circuit and the non-heart failure physiological event detection circuit and the comparison circuit, and configured to compute a non-heart failure physiological status indication using a logical combination of the heart failure event indication, the non-heart failure physiological event characteristic, and the comparison value; and

    wherein the non-heart failure physiological status indication indicates that the non-heart failure physiological event is absent, during the time period, whenthe heart failure event indication indicates that the heart failure event is present during the time period,the non-heart failure event characteristic indicates that the non-heart failure physiological event including the heart failure co-morbidity is present during the time period, andthe comparison value indicates that the at least one of the different physiological signals does meet the specified criterion indicative of the heart failure event.
