[Objective grading of stenosing coronary artery processes through the quantification of pathological-anatomical data...

Proceeding from an estimation of the hitherto known models of the judgement of the coronary arteriosclerosis and the achieved degree of quantificability methodic principles are developed to quantify the influence of pathologo-anatomical parameters on the myocardial infarction with the help of mathematical methods using electronic data processing. With the help of the comparison of evaluation schemata according to Herzog/Schoenmackers and Romaniuk/Schroder on the basis of 174 hearts coronarographed post mortem a possibility is demostrated to estimate objectively the efficiency of evaluation schemata. The improvement of the evaluation after inclusion of the absolute mass of the heart is demonstrated. Herzog/Schoenmackers's valuation after the mathematical judgement of the probationers examined results in a wrong coordination of altogether 15 per cent, Romaniuk/Schroder's valuatiom results in 12.6 per cent. After the inclusion of the abolute mass of the heart into this valuation a decrease of the malcoordination to 10.3 per cent was achieved.
