Abstract:
1. An apparatus comprising: two or more ambulatory physiological sensors configured to provide, to a user or automated process, a first heart failure status indicator using a first sensor selected from the two or more ambulatory physiological sensors and a second heart failure status indicator using a second sensor selected from the two or more ambulatory physiological sensors, the second sensor different from the first sensor; an external biomarker sensor, configured to provide information to the user or automated process about an amount of a biomarker present in a biological substance, wherein the amount of the biomarker present provides information about heart failure status; and a processor circuit, communicatively coupled to the at least one ambulatory physiological sensor and the external biomarker sensor, the processor configured to switch, in response to information from the biomarker sensor, from a first heart failure status detection mode detecting heart failure status using the first heart failure status indicator to a second heart failure status detection mode detecting heart failure status using a change over time in the second heart failure status indicator, the second heart failure status detection mode different from and having a higher specificity than the first heart failure status detection mode.
