[Estimating the angiographic risk from isotopic ventriculography in ischemic heart disease].

Le résumé fourni par la source

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.
