[A preliminary study on hemodynamic changes of the heart-asthenia syndrome]

In this paper, hemodynamic changes of 254 subjects were observed by using impedance cardiogram in a double-blind control method. The subjects were divided into 5 groups: heart-asthenia syndrome (98 cases), lung-asthenia syndrome (23 cases), spleen-asthenia syndrome (23 cases), kidney-asthenia syndrome (10 cases) and normal group (100 cases). The results showed that hemodynamic abnormalities occurred in the patients with heart-asthenia syndrome only, the changed regularities were that deficiency of both vital energy and Yin greater than deficiency of heart-Yang greater than deficiency of heart-energy greater than deficiency of heart-Yin. When stroke volume (SV), cardiac output (CO), cardiac index (CI), stroke volume index (SVI), heather index (HI), vascular compliance (C) and ejection fraction (EF) were decreased and total peripheral resistance (TPR) and systolic time interval (STI) were increased, the signs and heart-asthenia syndrome could be found in clinical practice. In conclusion, the above parameters had certain diagnostic value for heart-asthenia syndrome and could be subjective quantitative indices for evaluating effects of treating the heart-asthenia syndrome.
