Saliva test for the heart: How it can detect early heart failure, even before symptoms appear

Researchers are developing non-invasive saliva tests to detect heart failure early, potentially before symptoms appear. Studies have identified key salivary biomarkers, and a prototype device, eCaDI, is being developed for home use. This innovation promises greater accessibility and earlier intervention for heart health.
