AbstractIn clinical practice several biochemical markers are used for the diagnosis of myocardial infarction. Because of its extremely high specificity for myocardial damage, cardiac troponin I (cTn I) is frequently used. The aim of this study was to evaluate the diagnostic efficacy of postmortem cTn I determinations in pericardial fluid and serum and to compare these results with other biochemical markers and with structural findings used to diagnose acute myocardial ischaemia. We studied 89 cadavers with a mean age of 51.38 +/- 2.04 (SD 19.27 years). Cases were allocated to 1 of 4 diagnostic groups depending on the probable intensity of myocardial damage and cause of death. In pericardial fluid we obtained statistically significant differences for the four biochemical parameters, while in serum myosin heavy chains and myoglobin showed statistically significant differences. The highest levels of biochemical markers in pericardial fluid were observed in subjects who had died from definite myocardial infarction.
