摘要: Abstract A woman with Prinzmetal angina displayed spontaneous attacks of myocardial ischemia characterized by severe chest pain, hypotension, inferior-wall ST-segment elevation and transient complete heart block. Coronary arteriography during several fully developed spontaneously occurring demonstrated spasm a right coronary artery that appeared to be anatomically normal. The site, extent degree obstruction varied individual attacks. Immediately after an attack subsided the These observations suggest should attempted, if possible, clinical pain in patients angina. Even those who have focal atherosclerotic may additional distal arterial spasm. Spasm beyond proximal preclude use saphenous-vein bypass therapy alone. vasodilators important therapeutic measure.
