- W1965183594 abstract "From January 1970 to December 1977, transient reversible episodes of S-T segment elevation were documented in 138 patients (80 with angina only at rest, 58 with angina both on exertion and at rest). Electrocardiographic monitoring in 33 patients with hemodynamic monitoring revealed that (1) during 6,009 transient episodes of myocardial ischemia, pain was always a late phenomenon and, in some patients, often did not occur; (2) during such transient episodes, ST-T wave behavior was often variable in the same patient with alternation of elevation, depression or only T wave changes with or without pain; (3) independent of the direction of the S-T segment and T wave changes, the episodes were never preceded by an increase of the hemodynamic determinants of myocardial demand but were associated with obvious impairment of left ventricular function. Thallium scintigraphy in 32 patients revealed a regional massive and localized reduction of myocardial perfusion during S-T segment elevation and pseudonormalization of T waves. During S-T segment depression the reduction of thallium uptake was diffuse with fuzzy limits. Coronary angiography revealed no significant stenosis in 8 patients and single, double and triple vessel disease in 38, 34 and 26 patients, respectively. Angiography in all 37 patients studied during angina revealed a severe coronary vasospasm involving vessels with extremely variable extent of atherosclerosis. Severe arrhythmias were recorded in 27 patients, and a myocardial infarction occurred in 28. A total of five patients died within 1 month of hospital admission. Thus, variable intensity and extension of coronary vasospasm and the presence of collateral vessels may result in different degrees of ischemia and various electrocardiographic patterns with or without anginal pain. Vasospastic angina can occur in the presence of extremely variable degrees of coronary atherosclerosis and in any phase of ischemie heart disease. It may evolve into acute myocardial infarction and sudden death: Variant angina appears to be only its most striking electrocardiographic manifestation. When vasospastic angina is appropriately searched for, its incidence rate appears to be high." @default.
