Relation of basal coronary tone and vasospastic activity in patients with variant angina.
OBJECTIVE To examine the vasoconstrictor response to ergonovine and the vasodilator response to isosorbide dinitrate in spastic and non-spastic coronary segments from 31 patients undergoing serial angiographic follow up of variant angina. METHODS Coronary angiograms and ergonovine provocation tests were repeated at an interval of 45 (SD 15) months apart. While all 31 patients showed a positiv...
متن کاملCoronary Vasospastic Angina: Assessment by Multidetector CT Coronary Angiography
OBJECTIVE We aimed to describe the imaging findings of multidetector CT coronary angiography (MDCTA) in cases of vasospastic angina (VA) and to determine the accuracy of MDCTA in the identification of VA as compared with invasive coronary angiography with an ergonovine provocation test (CAG with an EG test). MATERIALS AND METHODS Fifty-three patients with clinically suspected VA were enrolled...
متن کاملMorphological Characteristics of Coronary€Arteries in Patients With€Vasospastic Angina
V asospastic angina (VSA) is a variant form of angina in which chest pain typically appears without provocation, is accompanied by transient ST-segment elevation, and usually resolves spontaneously or with rapid-acting nitroglycerin. Although VSA usually occurs in angiographically normal or near-normal coronary arteries, intravascular ultrasound studies (IVUS) have demonstrated early atheroscle...
متن کاملImpact of Asthma on the Development of Coronary Vasospastic Angina
Although asthma increases the risk of cardiovascular disease, little is known about the relation of asthma and its severity to coronary vasospastic angina (CVsA). We hypothesized that asthma contributed to the development of CVsA.Patients in this population-based cohort study were retrospectively collected from the Taiwan National Health Insurance database. Using propensity score matching, subj...
متن کاملCoronary Vasospastic Angina: Current Understanding and the Role of Inflammation.
UNLABELLED Coronary vasospastic angina (CVsA) plays an important role in myocardial ischemia including stable angina, acute coronary syndromes, and sudden cardiac death. Inflammation status from either endothelium or adventitia can cause endothelial dysfunction. Thereafter, the endothelial dysfunction further induces vascular smooth muscle hypercontraction through the enhanced rho-kinase with t...
