Harnessing Mobile Technology for Early Heart Failure Detection: Insights from the ECHOS3 Registry in Primary Care

Highlight

• A novel mobile phone application was used in primary care to screen for previously undiagnosed heart failure (HF), detecting HF in 34.1% of screened patients.
• The majority of newly diagnosed HF cases were HF with preserved ejection fraction (HFpEF), accounting for 70.1%.
• The newly developed ECHOS3 score demonstrated high sensitivity (88%) for HF screening but limited specificity (35%), providing a useful tool for early identification.
• Key predictors of HF included advanced age, atrial fibrillation, coronary artery disease, abnormal ECG, chronic kidney disease, and long-standing hypertension.
