Relationship of pulmonary diastolic and pulmonary wedge pressures to left ventricular diastolic pressures: role of acute myocardial infarction localization.

Right and left hemodynamics have been simultaneously studied in 127 patients with acute myocardial infarction with respect to electrocardiographic localization. Hemodynamic profiles of the different localizations suggest a high incidence of right ventricular dysfunction in infero-posterior infarcts. The comparison with the other localizations suggests that such a right ventricular dysfunction is likely to be responsible for an additional underestimation of left ventricular end-diastolic pressure when estimated by pulmonary diastolic pressure.
