In order to test the clinical value of ST/HR slope in patients with CHD, we observed CM_5 ST/HR slopefrom the view of CHD rehabilitation. Thirty-seven patients with CHD were divided randomly into two groups;Group I, consisting of 22 patients receiving QiGong therapy and Group II, 15 patients receiving placebo ascontrols. For each patient before and after the course of treatment, submaximal treadmill graded exercise testwere done in order to yield CM_5 ST/HR slope. The results showed that in Group I, there was a decrease inthe value of CM_5 slope. But no change or an increase was found in Group II. There was a statisticallysignificant difference between the two groups. However, as to ST segment depression and other indicesderived from routine exercise testing, there were no significant changes between the two groups. It was thusconcluded that CM_5 ST/HR slope could be a sensitive index for therapeutic effectiveness of myocardial ischemiaand for follow-up in patients with CHD.
