Dr Rajeev Malhotra (Massachusetts General Hospital, Boston, MA, US) discusses his abstract presented during AHA 2020. 

The investigators sought to determine if percent predicted peak oxygen pulse (%PredO2P, as defined by peak oxygen uptake/heart rate), a non-invasive measure combining stroke volume and peripheral oxygen extraction, could serve as a marker of the haemodynamic response (HR) to exercise in HFpEF patients.
