What is it about?
Measuring central blood pressure, the pressure your heart directly works against, usually requires invasive procedures. Our study shows that an ordinary arm cuff, combined with machine learning, can provide the same insights. By analyzing cardiac pulse waveforms from the arm, our method accurately reconstructs the full pressure cardiac cycle inside the aorta, offering a noninvasive way to assess heart health.

Why is it important?
An accurate reconstruction of the full central aortic pressure waveform from a brachial cuff allows to measure critical heart health markers non-invasively. This approach could help doctors better monitor cardiovascular risk and disease without the need for complex or invasive tests.
Perspectives
Our spectral machine learning approach offers an innovative solution for accurately reconstructing central aortic pressure waveforms from non-invasive brachial cuff recordings. This work highlights the transformative potential of machine learning in advancing cardiovascular diagnostics and emphasizes the need for scientifically grounded integration of such models into healthcare applications.
