In the late Eighties, a series of observations from several institutions around the world has dramatically revolutionized the traditional notion that the occurrence of myocardial infarction was related most of the time to the development of critical flow-limiting coronary stenosis. All these studies showed that the infarct-related artery had only ...
Kossowsky W A - - 1996
Although the existence of the postmyocardial infarction syndrome has now long been questioned, the Dressler symptom complex remains widely accepted as a distinct clinical entity. A patient is described whose twenty-five-year follow-up adds to our argument that there is no late or separate multisystem autoimmune disease following acute myocardial infarction. ...
