Pathological findings in coronary arteries associated with sudden death in Austria

50 witnessed sudden cardiac deaths in the age group between 20-50 years have been studied at autopsy. The most remarkable findings were a high percentage of stenosis and arteriosclerosis of the descending branch of the left coronary artery and a large amount of three vessel disease. It is clear that severe stenosis and sclerosis of the coronary arteries are not essentially related to sudden cardiac death, but a high number of vessels with moderate stenoses and sclerosis has been found. The severity of vessel disease has been evaluated by a coronary score, which takes the haemodynamic effects of the injured coronary arteries on the myocardium into account. We also noted that patients below 35 years of age who died of sudden cardiac death showed a very low coronary score.
