Relationship of Pulmonary Diastolic and Pulmonary Wedge Pressures to Left Ventricular Diastolic Pressures: Role of Acute Myocardial Infarction Localization

Abstract
Right and left hemodynamics were simultaneously studied in 127 patients with acute myocardial infarction with respect to ECG 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 additional underestimation of left ventricular end-diastolic pressure when estimated by pulmonary diastolic pressure.
