Does a MACD algorithm improve the prediction of worsening heart failure episodes compared to a RoT algorithm based on daily weight measurements?
Telemonitoring of weight alone may not have great value for heart failure management, as many episodes of worsening heart failure do not appear to be associated with weight gain.
A MACD algorithm is more specific but less sensitive than RoT when trying to predict episodes of WHF based on daily weight measurements. However, many episodes of WHF do not appear to be associated with weight gain and therefore telemonitoring of weight alone may not have great value for heart failure management.
