[Fluorescence of "intact" human myocardium in myocardial infarct]

Fluorescence analysis was used in comparison with other methods to study the morphologic-functional changes in the intact parts of the myocardium in 48 persons who had died of infarction and acute coronary insufficiency. The irregular intensity of primary and secondary cardiomyocyte fluorescence, the diversity of fluorescence, and the character of its colour and dynamics of its replacement are manifested in the earliest stages of ischemia. Quantitative measurements reveal diminution of primary fluorescence intensity at the onset of the disease and its gradual increase eventually.
