CHEST X-RAY IN ACUTE LEFT-VENTRICULAR POWER FAILURE - AID TO DETERMINING PROGNOSIS OF PATIENTS SUPPORTED BY INTRA-AORTIC BALLOON PUMPING

Serial chest x-rays were used as a means of evaluating the hemodynamic status of 43 patients in acute left ventricular power failure (LVPF) complicating acute myocardial infarction who were assisted with balloon pumping. The following findings were reported: 1. In patients with acute myocardial infarction, prediction of the hemodynamic status on the basis of chest x-rays is less reliable when severe LVPF is present as a complication. 2. The incidence and severity of roentgenographic findings of congestive heart failure and pulmonary edema are increased in patients with severe LVPF compared to patients with uncomplicated myocardial infarction. 3. Improvement in the roentgenographic degree of heart failure with positive clinical and hemodynamic responses to 24 hr or less of balloon pumping is an indication that patients in severe acute LVPF may survive. Patients with deteriorating or unchanging chest x-ray findings have an extremely poor prognosis. These patients should be evaluated by cardiac catheterization and coronary arteriography to determine the appropriateness of emergency surgical correction.
