A 57-year-old man with a history of hypertrophic cardiomyopathy diagnosed by echocardiography experienced atypical chest pain and dyspnea for 6 months. A rest Tc-MIBI myocardial SPECT imaging and a F-FDG myocardial PET/CT imaging were performed, which showed multiple matched myocardial perfusion/metabolism defects in the left ventricle, indicating scar tissue. Surprisingly, subsequent contrast coronary angiography revealed no significant coronary artery stenosis.
一位 57 岁男性，既往经超声心动图诊断为肥厚型心肌病，因非典型胸痛和呼吸困难 6 个月就诊。行静息 Tc-MIBI 心肌 SPECT 显像和 F-FDG 心肌 PET/CT 显像，结果显示左心室多处匹配的心肌灌注/代谢缺损，提示为瘢痕组织。令人惊讶的是，随后的冠状动脉造影未见明显冠状动脉狭窄。
