对36例各型肺心病患者及16例正常人进行核平衡法心血池显像,以观察其左心功能的情况.发现肺心病患者随着病情的加重,其左心高峰充盈率(left ventricuar peak filling rate;LPFR)和左心室射血分数(left ventricatar ejection fraction;LVEF)均逐渐下降,高峰充盈时间(peak filling time;TPFR)改变不明显,说明肺心病本身病情的轻重与心室泵功能有密切关系.
36 cases of various types of patients with cor pulmonale and 16 normal subjects were enrolled in this study, and their left ventricular function was observed.According to left ventricular hyperintense peak filling rate (LPFR) and left ventricatar ejection fraction (LVEF) decreased gradually and peak filling time (TPFR) did not change significantly, indicating that the severity of pulmonary heart disease and ventricular pump function close relationship.
