The aim of this study was to determine the role of Doppler echocardiography in establishing the prognosis of Stages to 4 cardiac failure. The echocardiographic indices of left ventricular filling were correlated with catheter data and the 2 year out come of patients. The study population included 54 patients examined prospectively in the context of an evaluation of their cardiac failure. Two years after the initial examination, 19 patients were dead or transplanted. Of the remaining 35 patients, 18 were reevaluated at 6 months. Of the echocardiographic parameters, "hyper normal" mitral flow with a high E/A ration indicated poor prognosis; when E/A > 2, the one year survival was 50% and the 2 year survival 42%. There was overlap between the groups of dead or transplanted and surviving patients only when the E/A ratio was between 2 and 3. The patients with E/A < 2 were all alive without any major events at 2 years. All patients with E/A > 3 had a poor prognosis. The E/A ratio was closely correlated with pulmonary capillary pressure levels (p < 0.001, r = 0.55) and lees closely with cardiac index (p < 0.05, r = 0.4) and radionuclide ejection fraction (p < 0.05, r = 0.28). After 6 months' vasodilator treatment with an angiotensin converting enzyme inhibitor (captopril) the E/A ratio decreased significantly from 1.85 +/- 0.78 to 1.0 0.55 (p < 0.02). A "hyper-normal" mitral flow is related to many factors, including high left ventricular filling pressures, mitral regurgitation and reduced left ventricular compliance. This appearance of mitral flow is a poor prognosis factor in severe cardiac failure.
