Importance of the Spasm Provocation Test in Diagnosing and Clarifying the Activity of Vasospastic Angina
Background: Some patients with Intractable Vasospastic Angina (i-VSA) have angina attacks, irrespective of vasodilator treatment. Despite the significance of the prediction of i-VSA in the clinical setting, the means to accomplish it remain unclear. Therefore, we investigated the relationship between i-VSA clinical parameters, including angiographic findings from the Spasm Provocation Test (SPT...
متن کاملImportance of a second spasm provocation test: Four cases with an initial negative spasm provocation test
The spasm provocation test (SPT) is an important test in the diagnosis of vasospastic angina (VSA). In many cases, this test is performed as the gold standard test, and VSA is considered not present if the SPT is negative. However, some patients continue to experience chest symptoms despite a negative SPT. In this study, we report four cases in which SPT was repeated to evaluate chest symptoms ...
متن کاملErgonovine echocardiography as a screening test for diagnosis of vasospastic angina before coronary angiography.
OBJECTIVES In patients with chest pain suggestive of variant angina, we performed this prospective study to test the specificity and diagnostic validity of ergonovine echocardiography (detection of regional wall motion abnormality during bedside ergonovine challenge) as a screening procedure before coronary angiography. BACKGROUND Spasm provocation test outside the catheterization room has ge...
متن کاملBlunted heart rate recovery is associated with coronary artery spasm in patients with suspected vasospastic angina
Background Autonomic nervous system activity has been shown to be altered in patients with vasospastic angina (VA). Heart rate recovery (HRR) is a simple, non-invasive measurement of autonomic nervous system dysfunction. We aimed to investigate whether HRR is related to VA, as established by an ergonovine test. Methods A total of 976 consecutive patients (47.5% male, mean age 55 years) withou...
متن کاملIncreased plasma level of endothelin-1 and coronary spasm induction in patients with vasospastic angina pectoris.
To elucidate the pathogenic contribution of a potent vasoconstrictor, endothelin-1, to coronary artery spasm, we provoked spasm with intracoronary administration of acetylcholine or ergonovine and performed sensitive immunoassays of plasma levels of endothelin-1 and atrial natriuretic factor (ANF) in the peripheral vein and coronary sinus of patients with a tentative diagnosis of vasospastic an...
