Variables with chronotropic response. A and B HR, HR exercise/rest ratio in different groups. No specific patterns observed with the increasing atherosclerotic burden after additionally adjustment of work rate. A significant decrease of HR AT/rest was noticed for NOCAD. C. HR/WR in different groups. An overall increasing pattern was noticed for HR/WR AT and peak, with increasing atherosclerotic burden. Both variable rocketed in AMI patients. *: P < 0.05 for full-adjusted model. Only significant pairwise comparisons between the closest adjusted mean were shown in the figure
