[Forensic medicine aspects of fatal coronary insufficiency with normal coronary arteries].

Clinical experiences give examples for the existence of various courses of anginal symptomatology even with cases of sudden heart death demonstrating angiographically normal coronary arteries. Pathogenetically may be considered spasms of regular or little changed coronary arteries, coronary muscle bridges and acute arrhythmias. In cases of recurrent myocardial ischemias an interstitial fibrosis and endocardial fibrosis can be proved histologically in the myocardial supply area. However an acute coronary insufficiency based on rheological and metabolic etiology cannot be found with morphological methods. The results are discussed, considering forensic aspects in cases of competitive causes of death.
