Pathological vascularization of the coronary intima.

Secondary vascularization was found in the walls of diseased coronary arteries from 36 individuals who died after sudden cardiac arrest. In the series presented here, coronary arteries of hospital patients dying from all causes also showed a 100% incidence of pathological neovascularization. A process linking neovascularization and chronic inflammation to an ultimate infectious aetiology is suggested.
