Symptomatic early coronary graft failure in bypass surgery patients: incidence, predictors and clinical impact.

ABSTRACT:

Objectives

Coronary graft failure (CGF) may occur early after coronary bypass graft surgery (CABG). The study aimed to identify clinical and perioperative risk factors and to evaluate the long-term clinical impact of symptomatic early CGF.

Methods

Patients who underwent clinically indicated coronary angiography (CAG) prior to post-CABG discharge between 2012 and 2022 were included. Symptomatic early CGF was defined as a dysfunctional coronary graft, evaluated on clinically indicated CAG, caused by stenosis of the proximal or distal anastomosis or bypass conduit, bypass occlusion, thrombosis, reduced flow (TIMI < 1) and kinking/tenting. Patients were divided into symptomatic early CGF and non-early CGF groups. Kaplan-Meier and multivariate analysis estimated cumulative surviv
