Coronary hemodynamic findings during spontaneous angina in patients with variant angina.
To define more completely regional coronary hemodynamic changes that occur during spontaneous angina pectoris in patients with variant angina, we measured coronary sinus and great cardiac vein blood flow (CSF and GCVF) and aortic and left ventricular pressures before and during spontaneous angina in six patients with variant angina. During spontaneous angina, ECGs in four patients showed eviden...
متن کاملSimilarities of ergonovine-induced and spontaneous attacks of variant angina.
Ergonovine has been shown to provoke attacks of variant angina, but a question remains whether spontaneous and ergonovine-induced attacks of variant angina are similar. Seven patients with variant angina undergoing cardiac catheterization were studied during transient episodes of spontaneous and ergonovine-induced rest angina with ST-segment elevation. Clinical, electrocardiographic, left ventr...
متن کاملStatins in Variant Angina
Variant angina pectoris (VAP) is a form of angina pectoris that shows transient ST-segment elevation on electrocardio-gram during an attack of chest pain and is caused by coronary artery spasm. Although the pathogenesis of coronary artery spasm has not been fully elucidated, endothelial dysfunction and enhanced vascular smooth muscle contractility play major roles in the pathogenesis of coronar...
متن کاملArrhythmias in Variant Angina Pectoris
Twenty-six patients with variant angina pectoris (VAP) were studied 1) to determine whether the degree of ST-segment elevation and R-wave changes correlate with the development of arrhythmias; and 2) to evaluate the relationship between the prevalence of arrhythmias, the severity of coronary artery disease, left ventricular function and wall motion. Serious arrhythmias were found in 12 patients...
متن کامل"Variant" Angina Pectoris
Classical angina pectoris is characterized by recurrent attacks of retrosternal pain brought on by effort and emotion and relieved by rest and the administration of nitroglycerin. It is well known that this classical syndrome has many variations and modifications. In 1959, and again in 1960, Prinzmetal and his colleagues described what they called a "variant form of angina pectoris." According ...
