title: Evaluation of eosin-fluorescence in the diagnosis of sudden cardiac death.
abstract: The diagnostic significance of the eosin-fluorescence method was evaluated and compared with the enzymehistochemical beta-hydroxybutyrate-dehydrogenase method (beta-HBDH) and the degree of hyperchromasia in 568 samples from 24 bets-HBDH-negative and beta-HBDH-positive sudden cardiac deaths (SCD) and 23 non-cardiac deaths as controls. The effect of autolysis was investigated separately on isolated human hearts at +4 degrees C and +22 degrees C. All samples were examined without any knowledge of clinical or autopsy data. Normal olive-green fluorescence was observed in only five individuals of the control group and two in the beta-HBDH-negative one. The frequency of the yellow-fluorescence and hyperchromasia increased from the control subjects towards the beta-HBDH-positive-ones. The difference in frequency distribution of fluorescence between the groups was statistically highly significant (P less than 0.001). The change in fluorescence did not correlate with the loss of beta-HBDH-reaction or the distribution pattern of hyperchromasia. Postmortem autolysis did not change the fluorescence significantly but the 78% wrong positive subjects in the control group render this method too sensitive and unreliable for medicolegal purposes.
