ABSTRACT: Objectives
Myocardial ischaemia following coronary artery bypass grafting (CABG) is a potentially devastating complication. Nevertheless, the incidence, aetiology and prognostic relevance of unplanned coronary angiography (uCAG) remain understudied. We aimed to investigate the prevalence and outcome of patients undergoing urgent, uCAG in the postoperative period following CABG.Methods
We screened all patients undergoing isolated elective CABG in an academic referral centre between 2016 and 2021 and identified patients undergoing uCAG within 30 days of surgery. For uCAG patients, a distinction was made between patients undergoing re-revascularization (REV) and patients receiving conservative management (CON). The primary outcomes were 30-day mortality and unadjusted and adjusted long-term survival. Secondary outcomes were the indication for and prevalence of uCAG and urgent revascularization.Results
Of the 1918 patients undergoing isolated CABG, 78 individuals needed uCAG (4.1%), of whom 45 underwent immediate revascularization (REV group; 2.3% overall, 57% within the uCAG group, median age 69.9 years) and 33 were treated conservatively (CONS group; 1.7% overall, 42% within the uCAG group, median age 69.1 years). Patients undergoing uCAG (n = 78) had a higher 30-day mortality than patients not undergoing uCAG (n = 1840, 30-day mortality: 9.0% vs 0.4%, P < 0.001). Long-term survival was significantly decreased in patients undergoing uCAG in both unadjusted (hazard ratio 2.20, 95% confidence interval 1.30-3.73) and EuroSCORE-, age- and sex-adjusted models (hazard ratio uCAG 2.03, 95% confidence interval 1.16-3.56).Conclusions
Unplanned postoperative coronary angiography is performed in 4.1% of isolated CABG procedures, and patients in need of such urgent invasive evaluation are subjected to decreased short- and long-term survival.
