Sudden death due to isolated segmentary coronary vasculitis.

ABSTRACT

Coronary vasculitis is a group of conditions occurring either independently or associated with another diseases characterized by an inflammation of the blood vessel's wall and subsequent fibrinoid necrosis, occlusion, stenosis, or aneurismal dilatations. Coronary vasculitis leading to sudden cardiac death has rarely been described in the scientific literature.We present the case of an 18-year-old football player who collapsed when playing football. The patient remained in a deep coma (glasgow coma scale = 3) in the hospital for another 4 hours before dying. During hospitalization, he was diagnosed with acute anterolateral myocardial infarction with ST elevation. An autopsy was performed the next day, and on the coronary vessels were identified a dilatation with luminal extension, which, based on clinical and pathological criteria, was considered to be an isolated, coronary polyarteritis nodosa.
