对 190 名急性心肌梗死患者进行了双能单光子发射计算机断层扫描 (SPECT)，使用锝-99m 焦磷酸 (Tc-99m PPi) 和铊-201 诊断右心室 (RV) 梗死的有效性，以及 RV 梗死的临床特征。右心室梗塞的诊断是通过在心肌梗塞发作后 2 至 9 天同步成像的双 SPECT 上的铊 201 和 Tc-99m PPi 重叠图像上的 RV 心肌中 Tc-99m PPi 积聚来进行的。 在 190 名左心室梗塞患者中，发现了 30 例右室梗塞（15.8%）：29 例（97%）与下梗死相关，1 例（3%）与侧梗塞相关。 Tc-99m PPi 积聚主要在右心室后壁观察到。血管造影显示 92% 的右心室梗塞患者右冠状动脉完全闭塞或严重狭窄。成功实现早期再灌注的患者的 RV 梗塞发生率显着低于未成功实现早期再灌注的患者（分别为 26.7% 和 68.4%，p
The validity of dual energy single-photon emission computed tomography (SPECT) with technetium-99m pyrophosphate (Tc-99m PPi) and thallium-201 for the diagnosis of right ventricular (RV) in farction, and the clinical features of RV infarction, were investigated in 190 patients with acute myocardial infarction. Diagnosis of RV infarction was performed by Tc-99m PPi accumulation in the RV myocardium on thallium-201 and Tc-99m PPi over-lay images at the dual SPECT with simultaneous imaging taken 2 to 9 days after the onset of myocardial infarction.Thirty RV infarctions were found among the 190 patients with left ventricular infarction (15.8%): 29 (97%) in association with the inferior and 1 (3%) with the lateral infarction. Tc-99m PPi accumulation was mostly observed in the posterior wall of the right ventricle. A total occlusion or a severe stenosis of the right coronary artery was demonstrated angiographically in 92% of the patients with RV infarction. The prevalence of RV infarctions was significantly lower in patients who achieved successful early reperfusion than in those who did not (26.7 vs 68.4%, respectively, p
