title: [Estimating the angiographic risk from isotopic ventriculography in ischemic heart disease].
abstract: The objective of this study was to determine the diagnostic accuracy of the ejection fraction (EF) measurement, calculated by isotopic ventriculography, to predict the angiographic risk in a group of patients with previous acute myocardial infarction and significant segmentary disturbance of wall motility. A total of 125 patients were studied (100 males and 25 females, aged 23 to 78 years). Isotopic EF showed positive and negative predictive values of 85% and 93.3%, respectively, for the low risk group. The corresponding values for the moderate risk group (angiographic EF from 31% to 54%) were 80.3% and 79.6%. And for the high risk group (angiographic EF < 31%) 89.4% and 83%. In conclusion, from the present work we state that with a high probability isotopic EF places each patient in his/her corresponding high, moderate, or low angiographic (biological) risk.
