Sponsor's own description
With regard to the characteristics of spasm segment, had been clearly described by other invasive imaging methods including intravascular ultrasound and optical coherence tomography. However, there is potential risk during these invasive procedures, such as severe myocardial ischemia or fatal arrhythmia. Presently available imaging test for coronary artery disease in multi detector-row computed tomography angiography (MDCTA) evaluation has high diagnostic accuracy to evaluate coronary artery stenosis. However, previous report assessing imaging findings or diagnostic accuracy of MDCTA in patients with vasospastic angina (VSA) is lacking.
