Fig. 2From: Influence of extracellular volume fraction on peak exercise oxygen pulse following thoracic radiotherapyIndependent predictors of peak exercise %O2 pulse. Legend: Panel A - correlation between LV ECVF and %O2 pulse. Panel B - correlation between resting LVEF and %O2 pulse. Panel C - correlation between cardiac V10Gy and %O2 pulse. Panel D shows the inverse correlation between NTproBNP and %O2 pulse. Abbreviations: %O2 pulse = %-predicted oxygen pulse; ECVF = extracellular volume fraction; LVEF = left-ventricular ejection fraction; V10Gy = %volume of the heart receiving ≥10 Gray; NTproBNP=N-terminal pro-brain natriuretic peptideBack to article page
