Stress Estimation in Elderly Oncology Patients Using Visual Wearable Representations and Multi-Instance Learning

ArXi:2604.06990v1 Announce Type: new Psychological stress is clinically relevant in cardio-oncology, yet it is typically assessed only through patient-reported outcome measures (PROMs) and is rarely integrated into continuous cardiotoxicity surveillance. We estimate perceived stress in an elderly, multicenter breast cancer cohort (CARDIOCARE) using multimodal wearable data from a smartwatch (physical activity and sleep) and a chest-worn ECG sensor.
