Background Syntax score (SS), which is an angiographic tool used in grading the complexity of coronary artery disease (CAD), has prognostic importance in coronary artery disease (CAD) and provides important information regarding selection of revascularization strategy. C‐reactive protein (CRP) and albumin are indicators of inflammation, and high levels of them are associated with high SS. We aimed to investigate whether baseline CRP to albumin ratio C‐Reactive Protein/Albumin Ratio (CAR), an easily available and novel inflammatory marker, is associated with SS. Method A total 403 consecutive patients with stabile angina pectoris, who underwent coronary angiography for suspected CAD from January 2015 to June 2016, were classified into two groups, low SS (≤22) and intermediate‐high SS (>22). Results C‐Reactive Protein/Albumin Ratio was significantly higher in patients with intermediate‐high SS group (P < .001). In multivariate regression analysis, CAR remained an independent predictor of intermediate‐high SS group together with hypertension and LDL. The predictive performance of CAR, CRP, and albumin was compared by ROC curve analysis. CAR surpassed CRP and albumin in predicting intermediate‐high SS group. CAR >6.3 predicted an intermediate‐high SS with sensitivity and specificity of 86.8% and 43.4%, respectively. Conclusion C‐Reactive Protein/Albumin Ratio was more tightly associated with the complexity and severity of CAD than CRP and albumin alone and was found to be an independent predictor for intermediate‐high SS group.
