Variables associated with cardiac output. A.VO2 in different groups. VO2 AT, VO2 peak decreased with increasing atherosclerotic burden. VO2 AT and peak were significantly lower in NOCAD compared with healthy volunteers. B.CO in different groups. CO AT, CO peak decreased with increasing atherosclerotic burden, with a dramatic drop observed from OCAD. C. VO2/HR in different groups. VO2/HR decreased with increasing atherosclerotic burden and dramatically dropped in AMI patients. *: P < 0.05 in full-adjusted model. Only significant pairwise comparisons between the closest adjusted mean were shown in the figure
