Clinical application of multi-detector computed tomography coronary angiography and global longitudinal strain for diagnosis of multi-vessel coronary artery spasm: case reports.

ABSTRACT:

Background

Diagnosis of epicardial coronary artery spasm, which is considered the cause of vasospastic angina, can be achieved through the coronary angiography (CAG) with a pharmacologic provocation test. However, this procedure is thought to have a potential risk of complications. Although multi-detector computed tomography coronary angiography (MDCTA) is proposed as the alternative test for the diagnosis of spastic coronary artery, myocardial ischaemia does not always coincide with coronary artery stenosis. MDCTA combined with echocardiographic left ventricular global longitudinal strain (LV GLS) is an innovative non-invasive diagnostic method expected to detect multivessel coronary artery spasm in patients with vasospastic angina.
