Coronary computed tomographic angiography (CCTA) is an established tool for the investigation of shortness of breath and chest pain. Although CCTA is performed to assess vessels that could well be diseased, one must review the study for evidence of cardiomyopathy, which can provoke similar symptoms. Cardiomyopathies can coexist with various causes of chest pain including obstructive coronary artery disease and may, therefore, be identifiable at CCTA. Furthermore, symptoms such as shortness of breath and chest pain that the clinician may suspect are secondary to coronary disease leading to investigation with CCTA, may be secondary to cardiomyopathy. We review several important causes of cardiomyopathy that may be detected by CCTA, which are important for radiologists to identify given the implications for further management and prognosis.
冠状动脉计算机断层扫描血管造影（CCTA）是一种用于评估呼吸急促和胸痛的既定工具。虽然 CCTA 是为了评估可能患病的血管而进行的，但必须检查研究是否有心肌病的证据，因为心肌病可能会引发类似的症状。心肌病可与各种胸痛原因共存，包括阻塞性冠状动脉疾病，因此可能在 CCTA 中被识别。此外，临床医生可能怀疑与冠状动脉疾病相关的呼吸急促和胸痛等症状导致 CCTA 检查，这些症状可能继发于心肌病。我们回顾了一些可能通过 CCTA 检测到的心肌病的重要原因，鉴于对进一步管理和预后的影响，这些原因对放射科医生来说很重要。
