BACKGROUND: The rate of saphenous vein graft (SVG) occlusion within the first year of bypass graft surgery is 15%. The CHA2DS2-VASc score is used to predict the risk of thromboembolic events in patients with nonvalvular atrial fibrillation. We aimed to evaluate the predictive role of the CHA2DS2-VASc score in the estimation of intracoronary thrombus burden in patients with acute myocardial infarction (AMI) who underwent SVG-PCI. METHODS: We retrospectively evaluated 221 patients who were admitted with AMI and underwent PCI of SVGs at the Department of Cardiology in the Turkiye Yuksek Ihtisas Education and Research Hospital between 2012 and 2018. The study population was divided into two groups according to their Thrombolysis in Myocardial Infarction (TIMI) thrombus grade: low thrombus burden (LTB; TIMI 0-3) and high thrombus burden (HTB; TIMI 4 and 5). RESULTS: The study included 221 patients with a mean age of 63.3 ± 6.7 years. The patients with HTB had significantly higher CHA2DS2-VASc scores (p < 0.001) compared with LTB patients. Univariate and multivariate regression analysis demonstrated that both CHA2DS2-VASc score (OR: 1.573, 95% CI: 1.153-2.147, p = 0.004) as a continuous variable and a binary cut-off level of the CHA2DS2-VASc score > 3 (OR: 3.876, 95% CI: 1.705-8.808, p = 0.001) were significantly associated with HTB. The ability of the CHA2DS2-VASc score to predict HTB burden was evaluated by receiver-operating characteristics analysis curve analysis. The optimum cut-off value of the CHA2DS2-VASc score for predicting HTB was 3 (with a sensitivity of 67.9% and a specificity of 69.3%) according to the Youden index. CONCLUSION: The CHA2DS2-VASc score can be used as an easy practical tool to predict HTB in AMI patients undergoing SVG-PCI.
