Abstract Aims The HeartLogic algorithm combines multiple implantable defibrillator (ICD) sensor data and has proved to be a sensitive and timely predictor of impending heart failure (HF) decompensation in cardiac resynchronization therapy (CRT‐D) patients. We evaluated the performance of this algorithm in non‐CRT ICD patients and in the presence of co‐morbidities. Methods and results The HeartLogic feature was activated in 568 ICD patients (410 with CRT‐D) from 26 centres. The median follow‐up was 26 months [25th–75th percentile: 16–37]. During follow‐up, 97 hospitalizations were reported (53 cardiovascular) and 55 patients died. We recorded 1200 HeartLogic alerts in 370 patients. Overall, the time IN the alert state was 13% of the total observation period. The rate of cardiovascular hospitalizations or death was 0.48/patient‐year (95% CI: 0.37–0.60) with the HeartLogic IN the alert state and 0.04/patient‐year (95% CI: 0.03–0.05) OUT of the alert state, with an incidence rate ratio of 13.35 (95% CI: 8.83–20.51, P
