New noninvasive method measures heart health in older adults without exercise

Researchers have created a new way to assess cardiorespiratory fitness in older adults without physical exertion. The method uses seismocardiography (SCG), a technique that captures subtle heart vibrations. This approach offers a richer dataset than traditional pulse or blood pressure checks. The study was led by Sundberg, Gates, and Boraxbekk. It validated SCG signals against established measures like VO2 max testing in a diverse group of older adults. The results confirmed SCG as a reliable alternative to exercise-based evaluations.

SCG works by detecting tiny vibrations from cardiac activity. Enhanced algorithms and machine learning then link these signals to cardiorespiratory capacity. This allows continuous, noninvasive monitoring aligned with personalised medicine principles.

The technology enables serial measurements, helping clinicians track cardiovascular health over time. Compact, lightweight sensors make remote monitoring possible. These sensors transmit data wirelessly, offering practical and unobtrusive use. The integration of SCG marks a shift in cardiovascular health assessment for older adults. It provides a noninvasive, reliable proxy for traditional fitness tests. Clinicians can now monitor and tailor interventions more effectively.
