Introduction
There were many causes of chest pain in patients. In addition to
coronary stenosis, coronary spasm and microcirculation lesions were also
common causes of chest pain [1]. Because there was
no ”gold standard” for the detection of myocardial microcirculation
lesions, especially for the diagnosis of myocardial microvascular spasm,
some patients were often missed and misdiagnosed. We reported a case of
ATP-induced microvascular spasm and the diagnostic value of
echocardiography.
