The RightAIDE study is a prospective, multicenter, observational registry designed to evaluate the real-world application of the HeartInsight™ algorithm for predicting acute heart failure (HF) events in patients implanted with a Biotronik ICD or CRT-D device with atrial sensing and Home Monitoring capability. Heart failure is a growing public health issue with high morbidity, mortality, and healthcare costs. HeartInsight, derived and validated in the SELENE HF study, integrates temporal trends of seven physiological variables monitored by the implanted device to provide early warnings of impending acute decompensation, with a median lead time of 42 days. This study aims to collect data on the implementation of a standardized workflow for interpreting and responding to HeartInsight alerts in routine clinical practice. Approximately 100 patients across 14 centers in Italy will be enrolled and followed for 12 months. The primary endpoint is the proportion of HeartInsight alerts considered "actionable," meaning they trigger at least one predefined clinical action (e.g., device reprogramming, therapy optimization, unscheduled visits, or hospital admission). Secondary endpoints include alert frequency, cumulative alert duration, number of patient interviews performed, hospitalizations during and outside alert periods, and the proportion of patients successfully using the HeartInsight Patient App. Data will be collected via electronic case report forms (eCRFs), analyzed descriptively, and monitored for quality. The study will generate insights into integrating HeartInsight-based predictive monitoring into clinical workflows to potentially improve patient management and outcomes.
