| 摘 要： | <正> This experiment was designed to see whether there is a significantdifference in FCG indexes between normal persons and patients with left ante-rior descending （LAD） coronary artery stenosis.Two groups were classifiedaccording to the findings of angiocardiographic examination.These personsalso underwent cardiac functional examination by noninvasive methods （i.e.STI and APG）.The results indicated that there was a significant difference between the coronaryheart disease （CHD） group and the control group consisting of normal persons.In the CHD group,PEP/LVET of STI indexes and Px,Py,Rx and Rxy ofFCG indexes augmented greatly and SV,CO and HI of APG indexes decreaseda little compared with the control group.So we can say that FCG is an extre-mely sensitive method for diagnosis of CHD.

| Abstract: | This experiment was designed to see whether there is a significant difference in FCG indexes between normal persons and patients with left ante- rior descending (LAD) coronary artery stenosis.Two groups were classified according to the findings of angiocardiographic examination.These persons also underwent cardiac functional examination by noninvasive methods (i.e. STI and APG). The results indicated that there was a significant difference between the coronary heart disease (CHD) group and the control group consisting of normal persons. In the CHD group,PEP/LVET of STI indexes and Px,Py,Rx and Rxy of FCG indexes augmented greatly and SV,CO and HI of APG indexes decreased a little compared with the control group.So we can say that FCG is an extre- mely sensitive method for diagnosis of CHD. |
