New multisensory telemonitoring device accurately identifies risk of worsening HF

Paris, France | The HeartLogic multi-sensor algorithm as an automatic predictor of heart failure events: results from the MultiSENSE Trial.

Presented at ESC Heart Failure 2017 by Roy Stuart GARDNER (Linithgow, United Kingdom)

Main results

Conclusion

This analysis shows that HeartLogic predicts the risk of an HF event independent of baseline variables. The Event Rate was ten times higher when HeartLogic was IN Alert vs. OUT of Alert State. HeartLogic was a better prognosticator than a baseline NT-proBNP.

A drawback of the comparison with analysis of NT-proBNP is that NT-proBNP was only measured at baseline, while the HeartLogic Index was measured daily. Plus, physicians were not blinded to NT-proBNP, which may have modified therapy, thereby possibly limiting its predictive accuracy.

Further studies are needed to establish if HeartLogic can improve patient outcomes.

Discussant Martin COWIE (London, GB) congratulated Gardner for extracting so much from these data. The challenge in telemonitoring studies has always been to get sense out of all the noise. The challenge lies in that that demands more than just risk stratification; you need to know what leads to meaningful clinical improvement.

He noted that the false positive rate seemed low in MultiSENSE, and he called these results one step ahead in the field of telemonitoring. A caveat lies in whether improvements in clinical outcomes justify the cost and logistical investments. Important to realise is also that not alerts are immediately actionable; a physician still needs to think about what causes the alert in this patient.

It was also noted that this system might be useful in acute heart failure, as decongestion often develops in the week before the acute event.
