Objectives

Narrative objectives1

Angina pectoris is a highly prevalent disease worldwide, which causes anginal chest symptoms due to myocardial ischemia by coronary artery stenosis and occlusion. Vasospastic angina (VSA), a subtype of angina pectoris, is based on the transient coronary vasoconstriction. Because VSA can be effectively managed by medical treatment, the accurate diagnosis of VSA is clinically important. When VSA is suspected but non-invasive testing is inconclusive, invasive diagnostic tests, including intracoronary acetylcholine (ACh) provocation, are recommended. The positive or negative ACh provocation testing was defined based on the angiographic vasospasm, electrocardiographic changes, and chest symptoms during the test. In real-world clinical practice, however, the diagnosis during ACh provocation testing is often challenging because of inconclusive angiographic vasospasm and atypical electrocardiographic changes and chest symptoms. Therefore, we designed the present study to evaluate the diagnostic potential of high sensitivity troponin as an objective marker for the diagnosis of VSA during ACh provocation testing.

Other related information

In clinical practice, high sensitivity troponin I (hs-TnI) is used for the diagnosis and risk stratification in patients with acute coronary syndrome (ACS). In patients with suspected ACS but without elevated hs-TnI levels, the presence of myocardial ischemia and the possibility of ACS are strongly suspected when remesured hs-TnI levels are elevated at intervals of 30 minutes to 2 hours. Measuring hs-TnI levels before and after ACh provocation tests may provide an objective and noninvasive assessment of myocardial ischemia related to coronary spasms. In this study, we will assess whether the elevation of hs-TnI levels is associated with coronary spasms during ACh provocation tests.
