“…In patients presenting with stable angina pectoris, CAG was indicated by the objective evidence of ischemia, including positive exercise stress testing or positive radionuclide noninvasive test [ 9 ]. Patients with a prior history of severe valvular heart disease, congenital heart disease, history of end-stage renal failure, liver failure, malignancy, emergent CABG surgery, lack of regular follow-up, and those who were non-adherent to their medical treatment were excluded [ 10 ]. Patients who received oral anticoagulation following surgery and patients whose preoperative CHA 2 DS 2 -VASc score could not be calculated because of insufficient data were also excluded.…”

Background and objectiveGraft patency is one of the major concerns after coronary artery bypass graft (CABG) surgery. The CHA 2 DS 2 -VASc [congestive heart failure, hypertension, age ≥75 years, diabetes mellitus (DM), stroke or transient ischemic attack (TIA), vascular disease, age 65 to 74 years, sex category] score is a tool that was developed to predict the risk of thrombotic events in patients with atrial fibrillation (AF). In this study, we evaluated the use of the CHA 2 DS 2 -VASc score as a simple tool for predicting graft failure (GF) among patients who underwent CABG surgery. MethodsIn this retrospective case-control study, a total of 280 patients were enrolled after applying the exclusion criteria. Angiograms were analyzed by using the QCA software system (Pie Medical Imaging, Maastricht, The Netherlands) for each patient. A graft was described as failed if it had 70% or more stenosis or was completely occluded. Patients were classified into two groups: group one included patients without GF (GF-N) and group two included patients with GF (GF-Y). Thereafter, the CHA 2 DS 2 -VASc risk score was calculated for each patient. ResultsIn our cohort, 136 patients had GF (GF-Y group) and 144 patients did not have GF (GF-N group). GF-N and GF-Y patients had their angiography performed 100.31 ± 8.04 and 103.49 ± 8.41 months after CABG, respectively. GF-Y group had a significantly higher rate of DM, hypertension, and heart failure with reduced ejection fraction (HFrEF). GF-Y group had higher CHA 2 DS 2 (GF-N group: 1.47 ± 0.91 vs. GF-Y group: 2.57 ± 1.17, p=0.0001) and CHA 2 DS 2 -VASc score (GF-N group: 2.80 ± 1.11 vs. GF-Y group: 4.15 ± 1.25, p=0.0001).Analyses showed that only CHA 2 DS 2 -VASc was an independent predictor of GF while other parameters including DM, hypertension, HFrEF, creatinine, and CHADS 2 were not found to be independent predictors of GF. A CHA 2 DS 2 -VASc score of >3 predicted GF with a sensitivity of 65.44% and a specificity of 74.31%. ConclusionsThe CHA 2 DS 2 -VASc score might be used as a feasible and simple method to predict the risk of GF after CABG surgery.
