A 65‐year‐old male with non‐ischaemic dilated cardiomyopathy, left bundle brunch block, and paroxysmal atrial fibrillation was implanted with a cardiac resynchronization therapy defibrillator in September 2017. After dismission, the patient was hospitalized again on 11 January 2018 (red line) for severe heart failure. At endovascular catheterization, an elevated left ventricular filling pressure was found. The retrospective HeartLogic index evaluation did show a previous number 16 crossing already on 2 November 2017 (blue line). Thus, an early warning for heart failure development did appear already 70 days before symptoms appearance that was mainly due to heart sounds (third, first) intensity modification. Patient died on 17 January 2018 despite resuscitation attempts.
