Contrasting Analysis Of The Results Of Treadmill Test For Patients With Coronary Heart Disease With Angina Pectoris And The Syndrome Differentiation Of Qi-yin Deficiency Or Plus Phlegm And Blood Stasis In TCM

Objective: to investigate the characters and laws of treadmill test (TET) indexes in patients with coronary heart disease (CHD) with angina pectoris (AP) and the syndrome differentiation of qi-yin deficiency or qi-yin deficiency plus phlegm and blood stasis in TCM simultaneously. Methods: 101 patients were divided into two groups: the qi- yin deficiency (QY group, 49 cases) and the qi-yin deficiency plus phlegm and blood stasis (QY plus group, 52 cases). All of patients accepted treadmill test and their results of treadmill test indexes were recorded and contrasted between two groups. The recorded contents included: ﹏egative or positive of TET; ﹖otal time of exercise; (3)max metabolic equivalent (Max MET); (4)the average of ST-segment depression at the exercise endpoint of test; ﹖he time of ST-segment depression 0.1 mv; ﹎etabolic equivalent at ST segment depression 0.1 mv; (7)QRS wave width before and after TET. Results: in QY plus group, the positive rates of TET were higher than those in QY group (PO.05); the average of ST-segment depressions at exercise endpoint of test (PO.01) and the differences of QRS waves width before and after TET (P<0.01) larger; the total time of exercise (PO.01), the max metabolic equivalent (P<0.01) and the metabolic equivalent at ST segment depression 0.1 mv (PO.05) lower; the required time of ST-segment depression 0.1 mv longer (PO.01); more patients were induced AP (PO.05) and less got to their target heart rate in the test. Conclusion: the exercise tolerances of patients in QY plus group were lower than those in QY group. It suggests that the syndrome differentiation of qi-yin deficiency plus phlegm and blood stasis were more severe period in TCM.
