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SPOPHYDS7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 2 6%时多数心功能处于 3～ 4级 ,当GEF值为 2 6%～ 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 To provide an objective and accurate quantitative indicator of the clinical status of cardiac function by means of gated nuclear pool imaging. Methods 393 cases of hospitalized patients with heart disease due to various cardiac disease check-in radionuclide blood pool examination of inpatients, with SPOPHYDS7 SPECT, FRANKFURT door procedures to obtain the left ventricular function parameters, according to the WHO classification of cardiac function, heart function points For 1 to 4 levels. Results There were significant differences in indexes of cardiac function between different grades of clinical heart function. The scores of GEF, PER and PFR tended to decrease from 1 to 4, and the EDV and PS increased in turn. When the GEF value was less than 36% The patients with decompensated functions accounted for 71.3% of the patients, while those with GEF values of less than 26% had grades 3 to 4, while those with GEF of 26% to 35% When the GEF value is greater than 36% of cardiac function at 1 to 2. At the same time, it showed that there was a significant correlation between various parameters of cardiovascular pool imaging and good correlation with clinical cardiac function classification, followed by EDV, GEF, PER, PFR and PS. Conclusion The parameters of nuclide heart pool imaging can directly, objectively and accurately reflect clinical cardiac function status, and provide other indicators such as wall motion and phase analysis
