BACKGROUND AND AIMS: early graft failure following coronary bypass surgery results in elevated morbidity and mortality. This study focused on the impact of angiographic graft evaluation. MATERIAL AND METHODS: of 5251 coronary artery bypass grafting (CABG) patients, 36 with postoperative persistent ischaemia underwent early angiography (23) or emergency resternotomy (13) 2000-2007 (Angiography era). Of the 23 patients, who underwent angiography, five were subsequently reoperated. Of 8807 CABG patients, 76 underwent postoperative emergency resternotomy 1988-1999 (Pre-angiography era) and served as controls. RESULTS: the angiography era patients were older (64.0 years vs. 58.2 years, P = 0.002) and the proportion of female patients (22% vs. 43%, P = 0.029) was smaller. The rate of emergency reoperations decreased (0.86% vs 0.34%, P < 0.001) during the Angiography era and graft repairs (P = 0.013) or additional grafts (P = 0.006) were less frequent, although occluded anastomoses were observed more often (P = 0.043). In 5 Angiography era patients graft complications were corrected with percutaneous coronary intervention. ICU stay (5.72 + 0.98 days vs. 5.53 + 0.68 days) and hospital stay (12.2 + 1.54 days vs. 13.1 + 1.63 days) did not differ between the groups, but the rate of myocardial infarction (63.8% vs. 92.1%, P < 0.001) and in-hospital death (22.2% vs. 46.1%, P = 0.015) decreased. CONCLUSION: after the introduction of early postoperative angiographic evaluation of CABG patients the rate of emergency reoperations and related morbidity and mortality decreased.
