Right ventricular infarction with shock but without significant left ventricular infarction: a new clinical syndrome.

Published

Journal Article

Right ventricular infarction has been described as concurrent with infarction involving the inferior (posterior) aspect of the left ventricular free wall and adjacent interventricular septum. Patients with right ventricular infarction typically show the ECG changes of inferior infarction in leads II, III, and aVF. This report describes two patients with right ventricular infarction but without changes in the QRS complex of the ECG, indicating an inferior infarct of the left ventricle. An autopsy-proven infarct of the right ventricular free wall with neither QRS nor other clinical evidence of left ventricular involvement was responsible for cardiogenic shock and death in one patient. This observation led to a review of a computerized data bank containing records of patients who had undergone cardiac catheterization to determine if there were other patients with clinical criteria suggesting right ventricular infarction without QRS changes of left ventricular infarction. One of the 167 patients with a history of a myocardial infarction also met the following clinical criteria: (1) transiently elevated total creatine kinase and creatine kinase myocardial band; (2) diffuse ST segment elevation without QRS changes indicative of left ventricular infarction on the ECG; (3) normal left ventricular function; (4) hemodynamic evidence of right ventricular dysfunction; and (5) cardiogenic shock.
