ABSTRACT 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).
PCI has become an alternative treatment for LM coronary artery disease, and risk scoring system might be beneficial for pre-PCI risk stratification.
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 m(2)). 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.
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.

    ABSTRACT: Objectives To compare the clinical outcomes following unprotected left main coronary artery (ULMCA) percutaneous coronary intervention (PCI) of ostial/midshaft lesions between first and new generation drug-eluting stents (DES). Background Clinical outcomes after treatment of ostial/midshaft lesions in ULMCA with first generation DES were favorable. However, to date, data regarding treatment for those lesion subsets with new generation DES have not been reported. Methods A total of 219 patients with ostial/midshaft lesions in ULMCA treated with first (n=139) or new generation DES (n=80) were analyzed. Results There was a higher prevalence of IVUS use (35.2% vs. 50.0%, p=0.032) and post-dilation (70.5% vs. 93.8%, p <0.001) with larger maximum balloon diameter (3.81±0.45 vs. 4.08±0.44, p <0.001) in the new generation DES group. At a median follow-up period of 730 days, there were no significant differences in the propensity-score adjusted analyses, for major adverse cardiac events (MACE) defined as composite endpoint of all-cause death, myocardial infarction and target vessel revascularization (HR [new vs. first generation DES]: 1.22; 95% CI: 0.64 to 2.31; p=0.549). Of note, target lesion revascularization rates at 2-years were only 0.9% and 2.7%, for first and new generation DES groups, respectively (p=0.339). On multivariable analysis, SYNTAX score (HR: 1.06; 95% CI: 1.02-1.11, p=0.006) and EuroSCORE (HR: 1.14; 95% CI: 1.00-1.31, p=0.051) were independent predictors for MACE. Conclusions This study suggests that new generation DES for ostial/midshaft lesions in ULMCA are associated with favorable clinical outcomes, similar to those observed with first generation DES. © 2014 Wiley Periodicals, Inc.

    ABSTRACT: We retrospectively analysed long-term outcomes after conventional coronary artery bypass grafting (CABG) between patients having left main (LM) disease who should have been assigned class II and those assigned class III recommendation for percutaneous coronary intervention (PCI) according to the 2010 European Society of Cardiology and the European Association for Cardio-Thoracic Surgery guidelines. From January 2000 to December 2009, conventional CABG was routinely employed in 180 consecutive patients with previously untreated and stable LM lesion. A comparison between two groups (CABG for PCI class II and CABG for PCI class III) was performed, looking at the primary endpoint of major adverse cardiac and cerebrovascular events (MACCE), including all-cause death, stroke [cerebral vascular accident (CVA)], myocardial infarction (MI) and repeat revascularization. We also analysed the effects of variables on MACCE at 8 years after the operation. The overall 8-year MACCE rates were significantly lower in the CABG for PCI class II group than in the CABG for PCI class III group (9.7% class II vs 31.1% class III; P = 0.0005). This was largely because of an increased rate of repeat revascularization (1.2% class II vs 13.8% class III; P = 0.0029). The cumulative rate of the combined outcomes of all death/CVA/MI was significantly lower in the CABG for PCI class II group (8.5% class II vs 19.2% class III; P = 0.048); there was no observed difference between the groups for all-cause death, CVA and MI. The SYNTAX score was demonstrated to be the only significant predictor of combined outcomes (Death/CVA/MI) at 8 years [odds ratio (OR) 1.05, P = 0.023], repeat revascularization at 8 years (OR 1.11, P = 0.0013) and MACCE at 8 years (OR 1.07, P < 0.0001). In our routine strategy of conventional CABG for LM disease, patients believed to be PCI candidates for LM disease have significantly better long-term outcomes as characterized by combined outcomes (Death/CVA/MI), repeat revascularization and MACCE. These results provide a suitable benchmark against which long-term outcomes of PCI for LM disease can be compared. The SYNTAX score, which was introduced to determine treatment for complex coronary disease, is indicative of long-term outcomes after CABG for LM disease.

    ABSTRACT: The aim of this study was to examine the hypothesis that pentraxin 3 (PTX3) can have a diagnostic value for predicting anatomical complexity of coronary artery stenosis as measured by the Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score.
