OBJECTIVE
To observe the exercise single photon emission computed tomography (SPECT) myocardial perfusion imaging of patients with myocardial bridge and assess the association between myocardial ischemia and extent of myocardial systolic compression.
METHODS
Seventeen patients with myocardial bridge diagnosed by coronary angiogram were included and underwent exercise SPECT myocardial perfusion imaging.
RESULTS
Abnormal SPECT perfusion imaging was evidenced in 12 out of 17 patients with myocardial bridge (2 out of 6 patients with systolic compression induced stenosis < 50%, 3 out of 4 patients with systolic compression induced stenosis between 50% - 75% and 7 out of 7 patients with the systolic compression induced stenosis between 75% - 100%).
CONCLUSION
Exercise stress SPECT myocardial perfusion imaging could detect myocardial ischemia in patients with myocardial bridge and abnormal perfusion is positively related to the extent of systolic compression induced stenosis.
目的
观察心肌桥患者运动单光子发射计算机断层扫描（SPECT）心肌灌注显像情况，评估心肌缺血与心肌收缩期受压程度之间的关系。
方法
纳入17例经冠状动脉造影诊断为心肌桥的患者，行运动SPECT心肌灌注显像。
结果
17例心肌桥患者中12例SPECT灌注显像异常（收缩期受压致狭窄＜50%的6例患者中2例，收缩期受压致狭窄在50% - 75%的4例患者中3例，收缩期受压致狭窄在75% - 100%的7例患者中7例）。
结论
运动负荷SPECT心肌灌注显像可检测心肌桥患者的心肌缺血情况，灌注异常与收缩期受压致狭窄程度呈正相关。
