First cardiological or cardiosurgical reintervention for ischemic heart disease after primary coronary artery bypass grafting1

Abstract

Reinterventions for ischemic heart disease by interventional cardiology or surgery are rather infrequent in the first decade after CABG but nearly half the patients surviving their second decade undergo one. The increased reintervention rate, apparent after 1985 did not go parallel with improved late post-CABG survival. Older age and the presence of multiple arterial grafts seem to reduce but also to bias the event. The very good survival, only when return of angina is present, suggests a more restrictive differential therapy approach, certainly in the presence of a well functioning arterial graft to the antero-septal region and where the co-morbidity might induce a high reinterventional survival cost.
