BACKGROUND: Acute decompensated heart failure (ADHF) carries a high event rate following discharge. The complex interplay between age, frailty and decongestion may lend itself to a functional test. METHODS: In the doorbell test the patient simulates answering the doorbell. They are timed rising from a recumbent position, bending over twice and walking 10 metres, this time is added to the change in respiratory rate. We aimed to determine if the doorbell test was associated with post ADHF events (death or readmission). The test was performed at hospital discharge, with follow up at 30-days and 1-year. RESULTS: In 74 patients at 30-days there was a 14% event rate. At 1-year there were 40 (54%) ..
