一位38歲女性有兩年勞累型心絞痛的症狀。心肌灌注掃描出現可回復心肌缺損以及暫時性心室擴大，高度懷疑有冠狀動脈狹窄，但是心導管顯示冠狀動脈無狹窄。綜合臨床病史、心電圖、心臟超音波以及心導管結果，最後診斷爲肥厚性心肌病變。在肥厚性心肌病變患者，心肌灌注掃描的異常對心肌缺氧很敏感，但不等同於冠狀動脈無狹窄。

A 38 year-old female had suffered from effort angina for 2 years. Myocardial perfusion imaging showed reversible redistribution and transient ventricular dilation, indicating high probability of coronary artery disease. Coronary catheterization revealed patent coronary arteries. Combining clinical history, electrocardiogram, echocardiography and coronary catheterization results, she was discharged with hypertrophic cardiomyopathy as final diagnosis. In conclusion, abnormalities in myocardial perfusion imaging are sensitive for myocardial ischemia in hypertrophic cardiomyopathy but not equal to coronary artery disease.
