This study introduces a new biosensor method for early detection of heart failure (HF) complications. Salivary TNF-alpha levels correlate with weight gain, potentially predicting HF decompensation.
Area of Science:
- Biomedical Engineering
- Cardiology
- Biomarker Discovery
Background:
- Heart failure (HF) management requires early detection of complications.
- Existing methods for monitoring HF decompensation can be invasive or delayed.
- Novel, non-invasive biomarkers are needed for timely intervention.
Purpose of the Study:
- To present a biosensor-based methodology for early detection of HF complications.
- To analyze specific biomarkers in saliva for HF monitoring.
- To validate the findings through a pilot study in clinical settings.
Main Methods:
- Development of a biosensor within the HEARTEN project for saliva analysis.
- Conducting a pilot study across two European hospitals (Spain and Italy).
- Measuring levels of specific biomarkers, including TNF-alpha, in patient saliva samples.
Main Results:
- A direct correlation was established between salivary TNF-alpha levels and patient weight.
- Weight gain in HF patients was identified as a predictor of decompensation.
- TNF-alpha emerged as a potential novel biomarker for HF decompensation events.
Conclusions:
- The developed biosensor methodology offers a promising approach for early HF complication detection.
- Salivary TNF-alpha shows potential as a non-invasive biomarker for predicting HF decompensation.
- This approach could significantly improve patient safety and HF management.
