【摘要】 对３０例肥厚型心肌病（ＨＣＭ）病人及２９例正常对照者做了心肌灌注显像及心血池显像，结果表明，ＨＣＭ病人均有不同程度的节段性左心室心肌肥厚，以室间隔部位不对称性肥厚最为典型；部份病人尚见有局部心肌灌注缺损，提示有心肌供血不足。心血池显像可见ＨＣＭ病人左心室收缩功能轻微增高，但舒张功能明显减低，以１／３充盈分数（１／３ＦＦ）及峰充盈时（ＴＰＦＲ）最为显著（Ｐ＜０．０１）。更多还原

【Abstract】 To assess the radionuclide imaging characteristics of hypertrophic cardiomyopathy(HCM), 99m Tc MIBI SPECT and 99m Tc RBC gated equilibrium angiography were performed in 30 HCM patients and 29 normal controls. HCM patients showed various left ventricular hypertrophy in different regional segments, mostly asymmetric septal hypertrophy; some segmental perfusion defects were also observed. In equilibrium angiography, HCM patients revealed a slightly increased systolic function but a definitely reduced diastolic function which in cases with 1/3 FF, PFR, TPFR were statistically significant( P <0.01). These findings are useful for the assessment of HCM. \ \更多还原
