[Clinical presentations mimicking acute myocardial infarction; therapeutic pitfalls]

Acute myocardial infarction remains one of the commonest causes of death. The pathogenesis is usually an occluding thrombus superimposed on a ruptured atherosclerotic plaque. However, several cardiac as well as non-cardiac diseases may give a presentation remarkably similar to acute myocardial infarction. Four patients are described, one woman aged 56 and three men aged 72, 63 and 60 years, who displayed the typical symptoms and ECG signs of acute myocardial infarction. The real conditions, however, were gallstones in two, a phaeochromocytoma in one and myocarditis in one. Two patients died, partly as the consequence of the failure to arrive at the correct diagnosis in time; the other two patients after adequate treatment were discharged in good condition.
