Case report of early signs of aortic stenosis decompensation detected via ambient sensor-derived digital biomarkers.

Background: Aortic stenosis is a progressive condition with a grim prognosis, underscoring the importance of timely intervention to prevent decompensation. Home monitoring systems, particularly those utilizing ambient sensors, offer promise in detecting early signs of deterioration. Case summary: We present the case of an 89-year-old woman who was asymptomatic but monitored using such a system prior to experiencing acute decompensation. Key clinical indicators, including increased night-time heart rate, respiration rate, toss and turns in bed, and nocturia, were observed several months before hospitalization. Additionally, reduced physical activity and increased toilet visits were noted. Discussion: These findings highlight the potential of ambient sensor systems in identifying pre-clinical stages of cardiac decompensation, especially in severe aortic stenosis cases. Integrating ambient sensor systems into routine clinical practice holds promise for enhancing proactive management strategies and reducing adverse outcomes associated with cardiovascular disease progression.
