目的应用门控核素心血池显像检测手段对临床心功能状态的判断提供一客观、准确的量化指标。方法选取我院393例因各种心脏疾病行门控核素心血池检查住院患者，用SPOPHY DS7型SPECT，FRANKFURT门处理程序，获得左室各功能参数，依据WHO心功能分级标准，将心功能分为1～4级。结果临床心功能不同级别间心血池显像所获各指标值明显不同，心功能1～4级，GEF、PER、PFR呈依次减低趋势，EDV及PS依次增大；GEF值小于36％时心功能处于失代偿期者占71．3％，当GEF值小于26％时多数心功能处于3～4级，当GEF值为26％～35％时，心功能多处于2～3级，当GEF值大于36％时心功能多处于1～2级。同时表明：心血池显像所获各项参数之间相关非常显著，且与临床心功能分级的相关性良好，依次为EDV、GEF、PER、PFR、PS。结论核素心血池显像所获各项参数能够直接、客观、准确反映出临床心功能状态，同时提供室壁运动、相位分析等其他指标。

Objective In order to use the gated cardiac blood-pool imaging well and truly judge clinical heart function. Methods 393 patients with various heart diseases were examined by the gated cardiac blood pool imaging using Sophy DS7 SPECT. The FRANKFURT processing was utilized to obtain the left ventricle function index. Heart function level was through divided into 4 classes according to WHO standard. Results The left ventricular function parameters had significant difference in different clinical heart function level. When heart function levels were 1 to 4 classes, GEF, PER,PFR were ordinal reduced, EDV, PS was ordinal increased. When GEF value was less than36%, decompensation of heart function was 71.3%. When GEF was less than 26% ,most patient's heart function were located 3～4 class. When GEF was 26 %～35 %, heart function was 2～3 classesin most cases. When GEF was more than 36 %, clinical function most was situated 1～2 class. There were significant relativity between the ventricular function parameters and clinical heart function class, devolution was EDV, GEF, PER, PFR, PS. Conclusion The left ventricular blood-pool imaging can well and truly reflect clinical heart function and offer ventricular wall action as well as phase analysis.
