  • 2013
  • Ingår i: The Lancet. - 0140-6736 .- 1474-547X. ; 381:9867, s. 639-650

    • Background The anatomical SYNTAX score is advocated in European and US guidelines as an instrument to help clinicians decide the optimum revascularisation method in patients with complex coronary artery disease. The absence of an individualised approach and of clinical variables to guide decision making between coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI) are limitations of the SYNTAX score. SYNTAX score II aimed to overcome these limitations. Methods SYNTAX score II was developed by applying a Cox proportional hazards model to results of the randomised all comers SYNTAX trial (n=1800). Baseline features with strong associations to 4-year mortality in either the CABG or the PCI settings (interactions), or in both (predictive accuracy), were added to the anatomical SYNTAX score. Comparisons of 4-year mortality predictions between CABG and PCI were made for each patient. Discriminatory performance was quantified by concordance statistics and internally validated with bootstrap resampling. External validation was done in the multinational all comers DELTA registry (n=2891), a heterogeneous population that included patients with three-vessel disease (26%) or complex coronary artery disease (anatomical SYNTAX score >= 33, 30%) who underwent CABG or PCI. The SYNTAX trial is registered with ClinicalTrials.gov, number NCT00114972. Findings SYNTAX score II contained eight predictors: anatomical SYNTAX score, age, creatinine clearance, left ventricular ejection fraction (LVEF), presence of unprotected left main coronary artery (ULMCA) disease, peripheral vascular disease, female sex, and chronic obstructive pulmonary disease (COPD). SYNTAX score II significantly predicted a difference in 4-year mortality between patients undergoing CABG and those undergoing PCI (p(interaction) 0.0037). To achieve similar 4-year mortality after CABG or PCI, younger patients, women, and patients with reduced LVEF required lower anatomical SYNTAX scores, whereas older patients, patients with ULMCA disease, and those with COPD, required higher anatomical SYNTAX scores. Presence of diabetes was not important for decision making between CABG and PCI (p(interaction) 0.67). SYNTAX score II discriminated well in all patients who underwent CABG or PCI, with concordance indices for internal (SYNTAX trial) validation of 0.725 and for external (DELTA registry) validation of 0.716, which were substantially higher than for the anatomical SYNTAX score alone (concordance indices of 0.567 and 0.612, respectively). A nomogram was constructed that allowed for an accurate individualised prediction of 4-year mortality in patients proposing to undergo CABG or PCI. Interpretation Long-term (4-year) mortality in patients with complex coronary artery disease can be well predicted by a combination of anatomical and clinical factors in SYNTAX score II. SYNTAX score II can better guide decision making between CABG and PCI than the original anatomical SYNTAX score.

  • Coronary artery bypass grafting vs. percutaneous coronary intervention for patients with three-vessel disease : final five-year follow-up of the SYNTAX trial
  • 2014
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 35:40, s. 2821-2830

    • Aims Coronary artery bypass grafting (CABG) has been considered the standard of care for patients with three-vessel disease (3VD), but long-term comparative results from randomized trials of CABG vs. percutaneous coronary intervention (PCI) using drug-eluting stents (DES) remain limited. Methods and results Patients with de novo 3VD or left main disease were randomly assigned to PCI with the paclitaxel-eluting first-generation stent or CABG in the SYNTAX trial. This pre-specified analysis presents the 5-year outcomes of patients with 3VD (n = 1095). The rate of major adverse cardiac and cerebrovascular events (MACCE) was significantly higher in patients with PCI compared with CABG (37.5 vs. 24.2%, respectively; P < 0.001). Percutaneous coronary intervention as opposed to CABG resulted in significantly higher rates of the composite of death/stroke/myocardial infarction (MI) (22.0 vs. 14.0%, respectively; P < 0.001), all-cause death (14.6 vs. 9.2%, respectively; P = 0.006), MI (9.2 vs. 4.0%, respectively; P = 0.001), and repeat revascularization (25.4 vs. 12.6%, respectively; P < 0.001); however, stroke was similar between groups at 5 years (3.0 vs. 3.5%, respectively; P = 0.66). Results were dependent on lesion complexity (P for interaction = 0.12); in patients with a low (022) SYNTAX score, PCI vs. CABG resulted in similar rates of MACCE (33.3% vs. 26.8%, respectively; P = 0.21) but significantly more repeat revascularization (25.4% vs. 12.6%, respectively; P = 0.038), while in intermediate (2332) or high (>= 33) SYNTAX score terciles, CABG demonstrated clear superiority in terms of MACCE, death, MI, and repeat revascularization. Differences in MACCE between PCI and CABG were larger in diabetics [hazard ratio (HR) = 2.30] than non-diabetics (HR = 1.51), although the P for interaction failed to reach significance for MACCE (P for interaction = 0.095) or any of the other endpoints. Conclusion Five-year results of patients with 3VD treated with CABG or PCI using the first-generation paclitaxel-eluting DES suggest that CABG should remain the standard of care as it resulted in significantly lower rates of death, MI, and repeat revascularization, while stroke rates were similar. For patients with low SYNTAX scores, PCI is an acceptable revascularization strategy, although at a price of significantly higher rates of repeat revascularization.

  • Geographic disparity in 10-year mortality after coronary artery revascularization in the SYNTAXES trial
  • 2022
  • Ingår i: International Journal of Cardiology. - : Elsevier. - 0167-5273 .- 1874-1754. ; 368, s. 28-38
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: To investigate geographic disparity in long-term mortality following revascularization in patients with complex coronary artery disease (CAD).Methods and results: The SYNTAXES trial randomized 1800 patients with three-vessel and/or left main CAD to percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and assessed their survival at 10 years. Patients were stratified according to the region of recruitment: North America (N-A, n = 245), Eastern Europe (E-E, n = 189), Northern Europe (N-E, n = 425), Southern Europe (S-E, n = 263), and Western Europe (W-E, n = 678), which also served as the reference group. Compared to W-E, patients were younger in E-E (62 vs 65 years, p < 0.001), and less frequently male in N-A (65.3% vs 79.6%, p < 0.001). Diabetes (16.0% vs 25.4%, p < 0.001) and peripheral vascular disease (6.8% vs 10.9%, p = 0.025) were less frequent in N-E than W-E. Ejection fraction was highest in W-E (62% vs 56%, p < 0.001). Compared to W-E, the mean anatomic SYNTAX score was higher in S-E (29 vs 31, p = 0.008) and lower in N-A (26, p < 0.001). Crude ten-year mortality was similar in N-A (31.6%), and W-E (30.7%), and significantly lower in E-E (22.5%, p = 0.041), N-E (21.9%, p = 0.003) and S-E (22.0%, p = 0.014). Compared to W-E, adjusted mortality in N-E (HR 0.85, p = 0.019) and S-E (HR 0.72, p = 0.043) remain significantly lower after adjustment for pre-and peri-procedural factors, but no significant interaction (Pinteraction = 0.728) between region and modality of revascularization was seen.Conclusion: In the era of globalization, knowledge, and understanding of geographic disparity are of paramount importance for the correct interpretation of global studies.

  • Causes of Death Following PCI Versus CABG in Complex CAD 5-Year Follow-Up of SYNTAX
  • 2016
  • Ingår i: Journal of the American College of Cardiology. - : Elsevier BV. - 0735-1097 .- 1558-3597. ; 67:1, s. 42-55

    • BACKGROUND There are no data available on specific causes of death from randomized trials that have compared coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI). OBJECTIVES The purpose of this study was to investigate specific causes of death, and its predictors, after revascularization for complex coronary disease in patients. METHODS An independent Clinical Events Committee consisting of expert physicians who were blinded to the study treatment subclassified causes of death as cardiovascular (cardiac and vascular), noncardiovascular, or undetermined according to the trial protocol. Cardiac deaths were classified as sudden cardiac, related to myocardial infarction (MI), and other cardiac deaths. RESULTS In the randomized cohort, there were 97 deaths after CABG and 123 deaths after PCI during a 5-year follow-up. After CABG, 49.4% of deaths were cardiovascular, with the greatest cause being heart failure, arrhythmia, or other causes (24.6%), whereas after PCI, the majority of deaths were cardiovascular (67.5%) and as a result of MI (29.3%). The cumulative incidence rates of all-cause death were not significantly different between CABG and PCI (11.4% vs. 13.9%, respectively; p = 0.10), whereas there were significant differences in terms of cardiovascular (5.8% vs. 9.6%, respectively; p = 0.008) and cardiac death (5.3% vs. 9.0%, respectively; p = 0.003), which were caused primarily by a reduction in MI-related death with CABG compared with PCI (0.4% vs. 4.1%, respectively; p <0.0001). Treatment with PCI versus CABG was an independent predictor of cardiac death (hazard ratio: 1.55; 95% confidence interval: 1.09 to 2.33; p = 0.045). The difference in MI-related death was seen largely in patients with diabetes, 3-vessel disease, or high SYNTAX (TAXUS Drug-Eluting Stent Versus Coronary Artery Bypass Surgery for the Treatment of Narrowed Arteries) trial scores. CONCLUSIONS During a 5-year follow-up, CABG in comparison with PCI was associated with a significantly reduced rate of MI-related death, which was the leading cause of death after PCI. Treatments following PCI should target reducing post-revascularization spontaneous MI. Furthermore, secondary preventive medication remains essential in reducing events post-revascularization.

  • Coronary artery bypass graft surgery versus percutaneous coronary intervention in patients with three-vessel disease and left main coronary disease : 5-year follow-up of the randomised, clinical SYNTAX trial
  • 2013
  • Ingår i: The Lancet. - 0140-6736 .- 1474-547X. ; 381:9867, s. 629-638

    • Background We report the 5-year results of the SYNTAX trial, which compared coronary artery bypass graft surgery (CABG) with percutaneous coronary intervention (PCI) for the treatment of patients with left main coronary disease or three-vessel disease, to confirm findings at 1 and 3 years. Methods The randomised, clinical SYNTAX trial with nested registries took place in 85 centres in the USA and Europe. A cardiac surgeon and interventional cardiologist at each centre assessed consecutive patients with de-novo three-vessel disease or left main coronary disease to determine suitability for study treatments. Eligible patients suitable for either treatment were randomly assigned (1: 1) by an interactive voice response system to either PCI with a first-generation paclitaxel-eluting stent or to CABG. Patients suitable for only one treatment option were entered into either the PCI-only or CABG-only registries. We analysed a composite rate of major adverse cardiac and cerebrovascular events (MACCE) at 5-year follow-up by Kaplan-Meier analysis on an intention-to-treat basis. This study is registered with ClinicalTrials.gov, number NCT00114972. Findings 1800 patients were randomly assigned to CABG (n=897) or PCI (n=903). More patients who were assigned to CABG withdrew consent than did those assigned to PCI (50 vs 11). After 5 years' follow-up, Kaplan-Meier estimates of MACCE were 26.9% in the CABG group and 37.3% in the PCI group (p<0.0001). Estimates of myocardial infarction (3.8% in the CABG group vs 9.7% in the PCI group; p<0.0001) and repeat revascularisation (13.7% vs 25.9%; p<0.0001) were significantly increased with PCI versus CABG. All-cause death (11.4% in the CABG group vs 13.9% in the PCI group; p=0.10) and stroke (3.7% vs 2.4%; p=0.09) were not significantly different between groups. 28.6% of patients in the CABG group with low SYNTAX scores had MACCE versus 32.1% of patients in the PCI group (p=0.43) and 31.0% in the CABG group with left main coronary disease had MACCE versus 36.9% in the PCI group (p=0.12); however, in patients with intermediate or high SYNTAX scores, MACCE was significantly increased with PCI (intermediate score, 25.8% of the CABG group vs 36.0% of the PCI group; p=0.008; high score, 26.8% vs 44.0%; p<0.0001). Interpretation CABG should remain the standard of care for patients with complex lesions (high or intermediate SYNTAX scores). For patients with less complex disease (low SYNTAX scores) or left main coronary disease (low or intermediate SYNTAX scores), PCI is an acceptable alternative. All patients with complex multivessel coronary artery disease should be reviewed and discussed by both a cardiac surgeon and interventional cardiologist to reach consensus on optimum treatment.

  • A Global Risk Approach to Identify Patients With Left Main or 3-Vessel Disease Who Could Safely and Efficaciously Be Treated With Percutaneous Coronary Intervention The SYNTAX Trial at 3 Years
  • 2012
  • Ingår i: JACC: Cardiovascular Interventions. - : Elsevier BV. - 1936-8798. ; 5:6, s. 606-617
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives The aim of this study was to assess the additional value of the Global Risk-a combination of the SYNTAX Score (SXscore) and additive EuroSCORE-in the identification of a low-risk population, who could safely and efficaciously be treated with coronary artery bypass graft surgery (CABG) or percutaneous coronary intervention (PCI).Background PCI is increasingly acceptable in appropriately selected patients with left main stem or 3-vessel coronary artery disease.Methods Within the SYNTAX Trial (Synergy between PCI with TAXUS and Cardiac Surgery Trial), all-cause death and major adverse cardiac and cerebrovascular events (MACCE) were analyzed at 36 months in low (GRC(LOW)) to high Global Risk groups, with Kaplan-Meier, log-rank, and Cox regression analyses.Results Within the randomized left main stem population (n = 701), comparisons between GRC(LOW) groups demonstrated a significantly lower mortality with PCI compared with CABG (CABG: 7.5%, PCI: 1.2%, hazard ratio [HR]: 0.16, 95% confidence interval [CI]: 0.03 to 0.70, p = 0.0054) and a trend toward reduced MACCE (CABG: 23.1%, PCI: 15.8%, HR: 0.64, 95% CI: 0.39 to 1.07, p = 0.088). Similar analyses within the randomized 3-vessel disease population (n = 1,088) demonstrated no statistically significant differences in mortality (CABG: 5.2%, PCI: 5.8%, HR: 1.14, 95% CI: 0.57 to 2.30, p = 0.71) or MACCE (CABG: 19.0%, PCI: 24.7%, HR: 1.35, 95% CI: 0.95 to 1.92, p = 0.10). Risk-model performance and reclassification analyses demonstrated that the EuroSCORE-with the added incremental benefit of the SXscore to form the Global Risk-enhanced the risk stratification of all PCI patients.Conclusions In comparison with the SXscore, the Global Risk, with a simple treatment algorithm, substantially enhances the identification of low-risk patients who could safely and efficaciously be treated with CABG or PCI.
