Abstract

Forty-four consecutive patients with acute myocardial infarction were studied with equilibrium radionuclide angiography (RNA) within 24 hours from the onset of symptoms, three days after admission and three days before hospital discharge (14 +/- 3 days). To assess the prognostic value of RNA derived parameters we assessed: the ejection fraction (EF), the left ventricular end-systolic volume index (ESVI), the left ventricular end-diastolic volume index (EDVI), the cardiac index (CI), the stroke volume index (SVI) and the peak systolic pressure/end-systolic volume index ratio (PSP/ESVI); we also determined Peel's prognostic index (PI) on admission and measured systolic arterial pressure (SAP), diastolic arterial pressure (DAP) and cardiac frequency (CF) as the same time as the radioisotopic parameters were taken. Thirty-nine patients were discharged without signs of ventricular failure with and without medical treatment (group A), 5 died during hospitalization (group B). Using EF alone, we obtained a very clear distinction between the two groups (Group A 43 +/- 12%; Group B 22 +/- 3%; p less than 0.005). Stepwise, multivariate analysis showed that, by linking PSP/ESVI to EF, we can even obtain a function that correlate better with hospital survival (F = 0.09832 X EF - 0.32035 X PSP/ESVI - 3.12981; p less than 0.002). There was good exponential correlation between EF and PSP/ESVI (r = 0.781) and this would seem to confirm that PSP/ESVI is a more sensitive contractility index for patients with a not very depressed EF.
