Non-exercise estimation of peak oxygen uptake in patients with ischaemic heart disease and heart failure using seismocardiography.

ABSTRACT:

Aims

Knowledge of cardiorespiratory fitness (i.e. VO₂peak) is important for determining prognosis and prescribing exercise for patients with heart disease undergoing cardiac rehabilitation (CR) programmes. In this explorative study, we investigated the accuracy of a novel equation using seismocardiography (SCG) at rest for the estimation of VO₂peak (SCG eVO₂peak) and whether it could detect changes following CR. An interim data analysis was planned after 50% of patients had undergone testing, allowing for adjustment of the SCG eVO₂peak. We compared the SCG eVO₂peak with a cardiopulmonary exercise test (CPET).

Methods and results

We included 125 patients with new-onset ischaemic heart disease (IHD, n = 58) or heart
