However, the relationship between SYNTAX score and CIN of patients with CTO undergoing PCI has been unclear. Methods We retrospectively enrolled 667 patients with CTO who underwent our institution′s basic PCI protocol between January 2010 and September 2012. The patients were divided into 3 groups： a low-risk group（SYNTAX score 〈 23; n = 231）, a moderate-risk group（SYNTAX score = 23-32; n = 214）, and a high-risk group（SYNTAX score〉32; n = 222）. CIN was defined as an absolute increase in SCr of ≥ 0.5 mg/d L over baseline values within 48-72 h after administration of contrast medium. We observed the correlation between SYNTAX score and the CIN rates. Results CIN developed in 74（11.09%） of the 667 study patients. The CIN rate showed a positive trend in the 3 groups based on the SYNTAX score, the higher SYNTAX score corresponds to the higher incidence of CIN（6.93%,13.08%,13.51%P = 0.044）. In the multivariate analysis, SYNTAX score was identified as an independent predictor of CIN（OR：1.956,95% CI： 1.014-3.773; P = 0.045; OR： 1.942,95% CI： 1.005-3.752; P = 0.048）. The incidence of in-hospital（1.3% vs. 4, 21% vs. 5.86%, P = 0.035） and long-term MACE（4.59% vs. 7.88% vs. 11.66%, P = 0.046） rates were more frequent in the higner SYNTAX score groups. Conclusions SYNTAX score is an independent predictor of CIN among patients with CTO undergoing PCI.展开更多

In this study we investigate the relationship between conventional risk factors of CAD with its complexity using SX score. Methods: The study consisted of 52 patients with CAD who were admitted to Cardiology Department—Menoufia University Hospitals for elective coronary angiography. The overall SX score was calculated prospectively using the SX score algorithm. Then comparison was done between populations with and without each risk factor. Results: There was a statistically significant correlation between age, hypertension, diabetes mellitus, dyslipidemia and smoking with SX score results (p 0.05). In a multivariate regression analysis, including conventional risk factors of CAD as independent covariates, it revealed that aging, having diabetes mellitus and smoking were identified as significant independent risk factors for CAD complexity. Conclusion: Advanced age, having diabetes mellitus and cigarette smoking are considered to be independent risk factors for the complexity of CAD. Therefore, when these factors present, we expect that the SX score of the patient to be high indicating a complex CAD.展开更多

It aims to assist in patient selection and risk stratification of patients with extensive CAD undergoing revascularization. However, the prognostic value of the Syntax score in patients undergoing percutaneous coronary intervention （PCI） has not been validated. The aim of this study was to evaluate its role in predicting long-term incidences of major adverse cardiac and cerebrovascular events （MACCE） in patients undergoing PCI for 3-vessel disease.Methods Two hundred and three consecutive patients with de novo 3-vessel CAD undergoing PCI with sirolimus-eluting stents were studied. Their angiograms were scored according to the Syntax score. The patients were divided into tertiles according to the Syntax score： lowest Syntax score tertile （Syntax score 〈22）, intermediate Syntax score tertile （Syntax score of 23 to 32）, and the highest Syntax score tertile （Syntax score 〉33）. During the 1-year follow-up, the MACCE-free survival curves were estimated by the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relation between the Syntax score and the incidence of MACCE. Performance of the Syntax score was studied with respect to predicting the rate of MACCE by receiver operator characteristic （ROC） curves with an area under the curve.Results The overall Syntax score ranged from 6 to 66 with mean ± standard deviation of 27.9±12.6 and a median of 26. At 1 year, the Syntax score significantly predicted the risk of MACCE （HR 1.07/U increase, 95% Cl 1.04 to 1.11, P 〈0.001）. The rate of MACCE was significantly increased among patients in the highest Syntax score tertile （17.9%） as compared with those with the lowest Syntax score tertile （1.4%, P 〈0.001） or intermediate Syntax score tertile （6.2%, P=0.041）. After the adjustment for all potential confounders, the Syntax score remained a significant predictor of the rate of MACCE （adjusted HR 1.12/U increase, 95% Cl 1.05 to 1.20, P 〈0.001）. The Syntax score accurately predicted MACCE with an area under the receiver operator curve of 0.77 （95% CI 0.65 to 0.90, P 〈0.001）. A Syntax score of 29.5 was identified as the optimal cutoff to predict MACCE with a sensitivity of 82.4% and specificity of 65.6%. Conclusion The Syntax score predicts the risk of MACCE in patients with 3-vessel disease undergoing PCI.展开更多
