摘要

Regadenoson (REG)是一种选择性腺苷A2a受体受体兴奋剂，在疑似冠状动脉疾病患者的核心肌灌注应激试验中用作诱导血管舒张的药物(1)。在这里，我们报告了一例REG输注引起杂音立即加重，左心室流出道(LVOT)梯度增加，导致该患者诊断为肥厚性梗阻性心肌病(HOCM)。

Hypertrophic obstructive cardiomyopathy diagnosed during regadenoson stress test

Regadenoson (REG) is a selective adenosine A2a receptor agonist which is used as an agent to induce vasodilation for the nuclear myocardial perfusion stress test in patients with suspected coronary artery disease (1). Here we report a case where REG infusion caused immediate accentuation of a murmur with an increase in the left ventricular outflow tract (LVOT) gradient, which led to the diagnosis of hypertrophic obstructive cardiomyopathy (HOCM) in this patient.
