Differential Incidence and Morphology of Spasm According to Coronary Arterial Location by Intracoronary Ergonovine Spasm Provocation Testing.
BACKGROUND We reported less provoked spasm in the left circumflex artery (LCX) by acetylcholine testing compared with the left anterior descending artery (LAD) and right coronary artery (RCA), so we investigated the clinical characteristics of provoked spasm in the LCX by ergonovine (ER) testing.Methods and Results:We retrospectively analyzed 1,185 consecutive cases of intracoronary ER testing ...
متن کاملThe angiographic effect of ergonovine and nifedipine in coronary artery spasm.
In a patient with variant angina, we have shown that the calcium-channel blocker nifedipine inhibits both spontaneous and ergonivine-induced coronary artery spasm. It had no effect, however, on the dose-related diffuse vasoconstriction caused by ergonovine, suggesting two distinct responses of coronary arteries to ergonovine provocation. Nifedipine did not cause epicardial coronary artery dilat...
متن کاملReduction of coronary blood flow during coronary artery spasm occurring spontaneously and after provocation by ergonovine maleate.
A 50-year-old man suffering from recurrent chest pain accompanied by transient ST-segment elevation developed spasm of the left anterior descending coronary artery after receiving ergonovine maleate. During spontaneous chest pain, thermodilution coronary sinus blood flow fell from 96 ml/min to 46 ml/min, while the coronary sinsu arteriovenous oxygen difference widened from 9.82 volumes percent ...
متن کاملIn vivo assessment of ergonovine-induced coronary artery spasm by 64-slice multislice computed tomography.
BACKGROUND The potential of multislice CT (MSCT) to predict coronary spasm has not been elucidated. The aim of this study was to investigate whether the morphological features observed on MSCT at the site of ergonovine-induced epicardial spasm could be used as diagnostic criteria for coronary spasm. METHODS AND RESULTS A total of 296 plaques in 199 patients with clinically suspected coronary ...
متن کاملReversible cardiac arrest related to late-onset coronary spasm after a positive ergonovine test.
scopic resection only should be considered for small (less than 3 cm) lesions in the outer third of the pulmonary parenchyma. However, as experience is gained with endo scopic surgical techniques and with the continued develop ment of improved instrumentation (such as endoscopic stapling devices), the indications for thoracoscopic pulmo nary resections are likely to increase. Currently, our app...
