Abstract:
Objective:To investigate the value of CHA2DS2-VASc score for predicting percutaneous coronary intervention (PCI) prognosis in patients with coronary chronic total occlusion.Methods:The clinical data of 139 patients with coronary chronic total occlusion who underwent PCI at the Second Hospital of Anhui Medical University from January 2019 to December 2020 were retrospectively analyzed. These patients were divided into good prognosis and poor prognosis groups according to prognosis outcomes. Univariate and multivariate Cox regression analysis was performed to evaluate the influential factors of adverse events after PCI in patients with coronary chronic total occlusion. The receiver operating characteristic curves were plotted to evaluate the value of the CHA2DS2-VASc score for predicting the occurrence of adverse events in patients with coronary chronic total occlusion undergoing PCI.Results:Among the 139 patients with coronary chronic total occlusion, the average follow-up time was (19.88 ± 7.90) months, 19 (13.7%) patients had a poor prognosis, and 120 (86.3%) patients had a good prognosis. The age, uric acid, and CHA2DS2-VASc score in the poor prognosis group were 73 (65.0, 77.0) years, (383.26 ± 120.60) μmol/L, and 4 (3, 5) points, respectively, which were significantly higher than 66 (57.0, 71.8) years, (322.68 ± 91.88) μmol/L, and 3 (2, 4) points in the good prognosis group ( U = -2.74, t = 2.24, U = -3.09, all P < 0.05). However, the proportion of patients with the successful opening of the occluded coronary artery and albumin, hemoglobin, and triacylglycerol levels in the poor prognosis group were 11 (57.9%), 36.7 (34.4, 38.3) g/L, (120.26±19.74) g/L, and 1.03 (0.85, 1.49) mmol/L, respectively, which were significantly lower than 98 (81.7%)( χ2 = 4.16, P = 0.041), 39.3 (36.78, 42.1) g/L ( U = -2.85, P = 0.004), (133.62 ± 16.84) g/L ( t = 1.52, P = 0.002), and 1.52 (1.09, 2.25) mmol/L ( U =-2.13, P = 0.033) in the good prognosis group. Multivariate Cox regression analysis showed that CHA2DS2-VASc score was a risk factor for poor prognosis of patients with coronary chronic total occlusion undergoing PCI (95% CI: 1.137-2.274, P = 0.007). The receiver operating characteristic curve analysis results showed that the area under the receiver operating characteristic curve plotted for CHA2DS2-VASc score predicting poor prognosis in patients with coronary chronic total occlusion undergoing PCI was 0.716 (95% CI: 0.588-0.844, P = 0.003), with the cut-off point of 3.5, the sensitivity of 68.4%, and specificity of 66.7%, respectively. Conclusion:Compared with those with a good prognosis, patients with a poor prognosis have a higher CHA2DS2-VASc score. The CHA2DS2-VASc score has a certain application value for predicting mid- and long-term prognosis in patients with coronary chronic total occlusion who undergo PCI.
