Uppsala Self-SCREENing of Heart Failure Study

The Stepwise Multimodal Home-Based HF Screening intervention involves a targeted community outreach program to identify undiagnosed heart failure (HF) in high-risk individuals. Participants randomized to the intervention arm (ACTIVE) are asked to self-collect dried blood spots for NTproBNP analysis. Those with elevated NTproBNP (≥125 pg/ml) in the dried blood spots are summoned to the study clinic and undergo confirmatory point-of-care NTproBNP testing and an AI-enabled echocardiogram, with the aim to confirm or rule out heart failure.
