Comparison of the predictive value of EuroSCORE,SYNTAX score,and clinical SYNTAX score for outcomes of patients undergoing percutaneous coronary intervention for unprotected left main coronary artery disease

Objectives : We aimed to assess the prognostic values of the EuroSCORE, SYNTAX score, and the novel Clinical SYNTAX score (CSS) for 30‐day and 1‐year outcomes in patients undergoing left main (LM) percutaneous coronary intervention (PCI). Background : PCI has become an alternative treatment for LM coronary artery disease, and risk scoring system might be beneficial for pre‐PCI risk stratification. Methods and Results : We enrolled 198 consecutive patients with unprotected LM disease undergoing PCI (mean age 71.5 ± 10.7 years). The CSS was calculated by multiplying the SYNTAX Score to (age/left ventricular ejection fraction +1 for each 10 mL the estimated glomerular filtration rate <60 mL/min per 1.73 m²). The endpoints were 30‐day, and 1‐year all‐cause death and major adverse cardiovascular events (MACE), which were defined as all‐cause death, nonfatal MI, and clinical‐driven target vessel revascularization. Comparing with the SYNTAX score, the predictive accuracy of CSS for 30‐day and 1‐year all‐cause death and MACE were significantly higher (c‐statistics, CSS versus SYNTAX score: P < 0.01 for 30‐day and 1‐year all‐cause death; P < 0.05 for 30‐day and 1‐year MACE, respectively). Furthermore, in the multivariate Cox regression analysis, both EuroSCORE and CSS were identified as the independent predictors of 30‐day and 1‐year all‐cause death and MACE, but the SYNTAX score was not. Conclusions : In the general practice among a high‐risk population undergoing LM PCI, EuroSCORE and CSS might be independent predictors for 30‐day and 1‐year all‐cause death and MACE. Furthermore, the CSS had a superior discriminatory ability in predicting the 30‐day and 1‐year clinical outcomes comparing with the SYNTAX score. © 2012 Wiley Periodicals, Inc.

Value of coronary artery calcium score to predict severity or complexity of coronary artery disease

Background

Prediction of severity or complexity of coronary artery disease (CAD) is valuable owing to increased risk for cardiovascular events. Although the association between total coronary artery calcium (CAC) score and severity of CAD, Gensini score was not used, it has been previously demonstrated. There is no information about the association between total CAC score and complexity of CAD.

Objectives

To investigate the association between severity or complexity of coronary artery disease (CAD) assessed by Gensini score and SYNTAX score (SS), respectively, and coronary artery calcium (CAC) score, which is a noninvasive method for CAD evaluation in symptomatic patients with accompanying significant CAD.

Methods

Two-hundred-fourteen patients were enrolled. Total CAC score was obtained before angiography. Severity and complexity of CAD was assessed by Gensini score and SS, respectively. Associations between clinical and angiographic parameters and total CAC score were analyzed.

Results

Median total CAC score was 192 (23.0-729.8), and this was positively correlated with both Gensini score (r: 0.299, p<0.001) and SS (r: 0.577, p<0.001). At multivariate analysis, it was independently associated with age (ß: 0.154, p: 0.027), male gender (ß: 0.126, p: 0.035) and SS (ß: 0.481, p< 0.001). Receiver-operating characteristic (ROC) curve analysis revealed a cut-off value > 809 for SS >32 (high SS tertile).

Conclusion

In symptomatic patients with accompanying significant CAD, total CAC score was independently associated with SS and patients with SS >32 may be detected through high Agatston score.

Significant association between score of periodontal disease and coronary artery disease

Recently, several researchers have demonstrated the association between periodontal disease and coronary artery disease (CAD). Therefore, we herein investigate the association between periodontal diseases and the existence of CAD among the study population who received both coronary angiography and dental examination. A total of 174 consecutive patients with dental examination including radiography and coronary angiography in the same hospitalization were recruited (64.5 ± 10.3 years, M/F: 94/80). A dentist assessed severity of periodontal status markers (bleeding on probing, probing depth ≥6 mm, teeth lost, alveolar bone resorption >half of root length by radiography and smoking status). We divided these patients into two groups according to whether they had CAD (CAD group, n = 99) or not (non-CAD group, n = 75) according to the results of coronary angiography. The composite periodontal risk scores calculated from periodontal status markers were higher in the CAD group than in the non-CAD group (P = 0.02). The composite periodontal scores were higher in the CAD group of age <60 years old population (P = 0.03) and in the CAD group of patients with normal glucose tolerance (P = 0.04). However, the difference was not significant in the age ≥60 years old population or those with diabetes mellitus or impaired glucose tolerance. In all populations, hypertension, glucose tolerance, statin therapy, and composite of periodontal risk scores were associated with CAD. Multivariate analyses revealed statin therapy, glucose tolerance, and periodontal risk scores were independent and significant risk factors for CAD. Composite periodontal risk scores were independent and significant predictive factors for CAD.
