Acute Myocardial Infarction with a Hemodynamic Pattern Resembling Constrictive Pericarditis

Abstract

A 49-year-old woman experienced acute myocardial infarction with a hemodynamic pattern resembling constrictive pericarditis. To clarify its mechanism, we performed right atrial pacing and volume challenge test during the chronic state. Although these two interventions elevated diastolic pressures of the both ventricles, the dip and plateau pattern was not reproduced. Factors other than ischemia may be important in producing a hemodynamic pattern resembling constrictive pericarditis in acute myocardial infarction. © 1991, International Heart Journal Association.
