应用核素心室造影对５０例甲亢患者进行左右心室收缩与舒张功能测定，结果左心室ＥＦ、ＳＶ比正常人减低（Ｐ＜０．０５），但ＣＯ反比正常人增高（Ｐ＜０．０１）；左心室ＰＦＲ亦减低（Ｐ＜０．０５），但ＰＥＲ却无明显减低（Ｐ＞０．０５）．右心室ＥＦ、ＰＥＲ、ＰＦＲ均有明显减低（Ｐ＜０．０１）。其中，３０例经心肺阻抗血流图检测结果与核素心室造影测定的结果相符。显示甲亢患者有心室功能受损明显，尤以右心室射血期最为显著。左室ＰＥＲ并未随左室ＰＦＥ的下降而减低，ＣＯ反而增加。甲亢（３０例）经过治疗症状控制后，复查左右心室功能均见ＥＦ、ＰＥＲ、ＰＦＲ明显升高，与治疗前相比有显著性差异。
Radionuclide ventricular systolic and diastolic function were measured in 50 patients with hyperthyroidism by radionuclide imaging. The results showed that EF and SV in left ventricle were lower than those in normal people (P <0.05) PFR in left ventricle was also decreased (P <0.05), but PER was not significantly reduced (P> 0.05). Right ventricular EF, PER, PFR were significantly reduced (P <0.01). Among them, 30 cases of cardiopulmonary impedance blood flow test results and radionuclide ventricular angiography results. Hyperthyroid patients showed significant impaired ventricular function, especially right ventricular ejection period the most significant. Left ventricular PER did not decrease with decreasing left ventricular PFE, while CO increased. Hyperthyroidism (30 cases) after treatment of symptoms, the review of left and right ventricular function were seen in EF, PER, PFR significantly increased, compared with before treatment were significantly different.
