- Antiplatelet therapy is the mainstay of pharmacologic treatment to prevent thrombotic or ischemic events in patients with coronary artery disease treated with percutaneous coronary intervention and those treated medically for an acute coronary syndrome. The use of antiplatelet therapy comes at the expense of an increased risk of bleeding complications. Defining the optimal intensity of platelet inhibition according to the clinical presentation of atherosclerotic cardiovascular disease and individual patient factors is a clinical challenge. Modulation of antiplatelet therapy is a medical action that is frequently performed to balance the risk of thrombotic or ischemic events and the risk of bleeding. This aim may be achieved by reducing (ie, de-escalation) or increasing (ie, escalation) the intensity of platelet inhibition by changing the type, dose, or number of antiplatelet drugs. Because de-escalation or escalation can be achieved in different ways, with a number of emerging approaches, confusion arises with terminologies that are often used interchangeably. To address this issue, this Academic Research Consortium collaboration provides an overview and definitions of different strategies of antiplatelet therapy modulation for patients with coronary artery disease, including but not limited to those undergoing percutaneous coronary intervention, and consensus statements on standardized definitions.

- 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.

- Aims The aim of this investigation was to determine the incidence and multivariable correlates of long-term (4-year) mortality in patients treated with surgical or percutaneous revascularization in the synergy between percutaneous coronary intervention (PCI) with TAXUS Express and Cardiac Surgery (SYNTAX) trial. Methods and results A total of 1800 patients were randomized to undergo coronary artery bypass graft (CABG) surgery (n = 897) or PCI (n = 903). Prospectively collected baseline and peri- and post-procedural data were used to determine independent correlates of 4-year all-cause death in the CABG and the PCI arms (Cox proportional hazards model). Four-year mortality rates in the CABG and the PCI arms were 9.0% [74 deaths (12 in-hospital)] and 11.8% [104 deaths (16 in-hospital)], respectively (log-rank P-value = 0.063). Censored data comprised 78 patients (8.7%) in the CABG arm, and 24 patients (2.7%) in the PCI arm (log-rank P-value < 0.001). Within the CABG arm, the strongest independent correlates of 4-year mortality were lack of discharge aspirin [hazard ratio (HR) 3.56; 95% CI: 2.04, 6.21; P < 0.001], peripheral vascular disease (PVD) (HR: 2.65; 95% CI: 1.49, 4.72; P = 0.001), chronic obstructive pulmonary disease, age, and serum creatinine. Within the PCI arm, the strongest independent correlate of 4-year mortality was lack of post-procedural anti-platelet therapy (HR: 152.16; 95% CI: 53.57, 432.22; P < 0.001), with 10 reported early (within 45 days) in-hospital deaths secondary to multifactorial causes precluding administration of anti-platelet therapy. Other independent correlates of mortality in the PCI arm included amiodarone therapy on discharge, pre-procedural poor left ventricular ejection fraction, a 'history of gastrointestinal bleeding or peptic ulcer disease', PVD (HR: 2.13; 95% CI: 1.26, 3.60; P = 0.005), age, female gender (HR: 1.60; 95% CI: 1.01, 2.56; P = 0.048), and the SYNTAX score (Per increase in 10 points: HR: 1.25; 95% CI: 1.06, 1.47; P = 0.007). Conclusion Independent correlates of 4-year mortality in the SYNTAX trial were multifactorial. Lack of discharge aspirin and lack of post-procedural anti-platelet therapy were the strongest independent correlates of mortality in the CABG and the PCI arms, respectively. Peripheral vascular disease is a common independent correlate of 4-year mortality and may be a marker of the severity of baseline coronary disease and risk of future native coronary disease (and extra-cardiac disease) progression.

- Background-There is a paucity of data on the use of optimal medical therapy (OMT) in patients with complex coronary artery disease undergoing revascularization with percutaneous coronary intervention or coronary artery bypass grafting (CABG) and its long-term prognostic significance. Methods and Results-The Synergy Between Percutaneous Coronary Intervention With TAXUS and Cardiac Surgery (SYNTAX) trial is a multicenter, randomized, clinical trial of patients (n=1800) with complex coronary disease randomized to revascularization with percutaneous coronary intervention or CABG. Detailed drug history was collected for all patients at discharge and at the 1-month, 6-month, 1-year, 3-year, and 5-year follow-ups. OMT was defined as the combination of at least 1 antiplatelet drug, statin, beta-blocker, and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. Five-year clinical outcomes were stratified by OMT and non-OMT. OMT was underused in patients treated with coronary revascularization, especially CABG. OMT was an independent predictor of survival. OMT was associated with a significant reduction in mortality (hazard ratio, 0.64; 95% confidence interval, 0.48-0.85; P=0.002) and composite end point of death/myocardial infarction/stroke (hazard ratio, 0.73; 95% confidence interval, 0.58-0.92; P=0.007) at the 5-year follow-up. The treatment effect with OMT (36% relative reduction in mortality over 5 years) was greater than the treatment effect of revascularization strategy (26% relative reduction in mortality with CABG versus percutaneous coronary intervention over 5 years). On stratified analysis, all the components of OMT were important for reducing adverse outcomes regardless of revascularization strategy. Conclusions-The use of OMT remains low in patients with complex coronary disease requiring coronary intervention with percutaneous coronary intervention and even lower in patients treated with CABG. Lack of OMT is associated with adverse clinical outcomes. Targeted strategies to improve OMT use in postrevascularization patients are warranted.

- The frequency of and relationship between hospital readmissions and outcomes after revascularization for left main coronary artery disease (LMCAD) are unknown.The purpose of this study was to study the incidence, predictors, and clinical impact of readmissions following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for LMCAD.In the EXCEL (XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, 1,905 patients with LMCAD were randomized to PCI vs CABG. The cumulative incidence of readmissions was analyzed with multivariable Anderson-Gill and joint frailty models to account for recurrent events and the competing risk of death. The impact of readmission on subsequent mortality within 5-year follow-up was determined in a time-adjusted Cox proportional hazards model.Within 5 years, 1,868 readmissions occurred in 851 of 1,882 (45.2%) hospital survivors (2.2 ± 1.9 per patient with readmission[s], range 1-16), approximately one-half for cardiovascular causes and one-half for noncardiovascular causes (927 [49.6%] and 941 [50.4%], respectively). One or more readmissions occurred in 463 of 942 (48.6%) PCI patients vs 388 of 940 (41.8%) CABG patients (P = 0.003). After multivariable adjustment, PCI remained an independent predictor of readmission (adjusted HR: 1.22; 95% CI: 1.10-1.35; P < 0.0001), along with female sex, comorbidities, and the extent of CAD. Readmission was independently associated with subsequent all-cause death, with interaction testing indicating a higher risk after PCI than CABG (adjusted HR: 5.72; 95% CI: 3.42-9.55 vs adjusted HR: 2.72; 95% CI: 1.64-4.88, respectively; Pint = 0.03).In the EXCEL trial, readmissions during 5-year follow-up after revascularization for LMCAD were common and more frequent after PCI than CABG. Readmissions were associated with an increased risk of all-cause death, more so after PCI than with CABG.

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.

- Percutaneous coronary intervention (PCI) is often favoured over coronary artery bypass grafting (CABG) surgery for revascularization in patients with chronic obstructive pulmonary disease (COPD). We studied whether COPD affected clinical outcomes according to revascularization in the Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization (EXCEL) trial, in which PCI with everolimus-eluting stents was non-inferior to CABG for the treatment of patients with left main coronary artery disease and low or intermediate SYNTAX scores. Patients with a history of COPD were propensity score matched to those without COPD. Outcomes at 30 days and 3 years in both groups were compared in patients randomized to PCI versus CABG. RESULTS: COPD status was available for 1901 of 1905 randomized patients (99.8%), 148 of whom had COPD (7.8%). Propensity score matching yielded 135 patients with COPD and 675 patients without COPD. Patients with COPD had higher 3-year rates of the primary composite end point of death, myocardial infarction or stroke (31.7% vs 14.5%, P 0.0001), death (17.1% vs 7.5%, P = 0.0005) and myocardial infarction (18.3% vs 7.3%, P 0.0001), but not stroke (3.3% vs 2.9%, P = 0.84). There were no statistically significant interactions in the relative risks of PCI versus CABG for the primary composite end point in patients with and without COPD at 30 days [hazard ratio (HR) 0.39, 95% confidence interval (CI) 0.12 1.21 vs HR 0.55, 95% CI 0.29 1.06; Pinteraction = 0.61] or at 3 years (HR 0.85, 95% CI 0.46 1.56 vs HR 1.28, 95% CI 0.84 1.94; Pinteraction = 0.27). CONCLUSIONS: In the EXCEL trial, COPD was independently associated with poor prognosis after left main coronary artery disease revascularization. The relative risks of PCI versus CABG at 30 days and 3 years were consistent in patients with and without COPD..

- Transcatheter aortic valve implantation is an established, guideline-endorsed treatment for severe aortic stenosis. Precise sizing of the balloon-expandable Myval transcatheter heart valve (THV) series with the aortic annulus is facilitated by increasing its diameter in 1·5 mm increments, compared with the usual 3 mm increments in valve size. The LANDMARK trial aimed to show non-inferiority of the Myval THV series compared with the contemporary THVs Sapien Series (Edwards Lifesciences, Irvine, CA, USA) or Evolut Series (Medtronic, Minneapolis, MN, USA).In this prospective, multinational, randomised, open-label, non-inferiority trial across 31 hospitals in 16 countries (Germany, France, Sweden, the Netherlands, Italy, Spain, New Zealand, Portugal, Greece, Hungary, Poland, Slovakia, Slovenia, Croatia, Estonia, and Brazil), 768 participants with severe symptomatic native aortic stenosis were randomly assigned (1:1) to the Myval THV or a contemporary THV. Eligibility was primarily decided by the heart team in accordance with 2021 European Society of Cardiology guidelines. As per the criteria of the third Valve Academic Research Consortium, the primary endpoint at 30 days was a composite of all-cause mortality, all stroke, bleeding (types 3 and 4), acute kidney injury (stages 2-4), major vascular complications, moderate or severe prosthetic valve regurgitation, and conduction system disturbances resulting in a permanent pacemaker implantation. Non-inferiority of the study device was tested in the intention-to-treat population using a non-inferiority margin of 10·44% and assuming an event rate of 26·10%. This trial is registered with ClinicalTrials.gov, NCT04275726, and EudraCT, 2020-000137-40, and is closed to new participants.Between Jan 6, 2021, and Dec 5, 2023, 768 participants with severe symptomatic native aortic stenosis were randomly assigned, 384 to the Myval THV and 384 to a contemporary THV. 369 (48%) participants had their sex recorded as female, and 399 (52%) as male. The mean age of participants was 80·0 years (SD 5·7) for those treated with the Myval THV and 80·4 years (5·4) for those treated with a contemporary THV. Median Society of Thoracic Surgeons scores were the same in both groups (Myval 2·6% [IQR 1·7-4·0] vs contemporary 2·6% [1·7-4·0]). The primary endpoint showed non-inferiority of the Myval (25%) compared with contemporary THV (27%), with a risk difference of -2·3% (one-sided upper 95% CI 3·8, pnon-inferiority<0·0001). No significant difference was seen in individual components of the primary composite endpoint.In individuals with severe symptomatic native aortic stenosis, the Myval THV met its primary endpoint at 30 days.Meril Life Sciences.

- ObjectivesTo investigate the prognostic implications of the presence of severe lesion calcification in patients undergoing coronary artery bypass graft (CABG) operation. BackgroundThere is robust evidence that lesion calcification is a predictor of worse prognosis in patients undergoing percutaneous coronary intervention; however, there is limited data about the prognostic implication of lesion calcium in patients treated with CABG. MethodsWe retrospectively analyzed data from 1,545 patients who underwent CABG and were recruited in the SYNTAX study and CABG registry. Two experts reviewed the angiographic data and classified patients in two groups: those with severely calcified coronary arteries and those without severe lesion calcification. Clinical outcomes at 5-year follow-up were collected and compared in the two groups. ResultsOne out of three patients exhibited severe lesion calcification (n=588). Patients with calcified coronaries had an increased mortality at 5-year follow-up (17.1% vs. 9.9%, P<0.001) and a higher event rate of death-myocardial infarction (MI) compared with those without (19.4% vs. 13.2%, P=0.003), but there was no statistical significant difference between the two groups for major adverse cardiovascular events (MACE, 26.8% vs. 21.8%, P=0.057). In multivariate Cox regression analysis severe lesion calcification was an independent predictor of an increased all-cause mortality (hazard ratio: 1.39, 95% confidence interval: 1.02-1.89; P=0.037) but it was not an independent predictor of the combined end-points death-MI or MACE. ConclusionsSevere lesion calcification is associated with an increased mortality in patients undergoing CABG, but it is not an independent predictor of death-MI or MACE. This paradox can be attributed to the fact that CABG allows perfusion of the healthy coronaries bypassing the diseased arteries and thus it minimizes the risk of coronary events due to progressive atherosclerosis.

- Aims: The aimof the present investigationwas to determine the long-termprognostic association of post-procedural cardiac enzyme elevation within the randomised Synergy between Percutaneous Coronary Intervention (PCI) with TAXUS and Cardiac Surgery (SYNTAX) Trial. Methods: 1800 patients with unprotected left main or de novo three-vessel coronary artery disease were randomised to undergo coronary artery bypass graft (CABG) surgery or PCI. Per protocol patients underwent post-procedural blood sampling with creatine kinase (CK), and the cardiac specific MB iso-enzyme (CK-MB) only if the preceding CK ratiowas = 2x the upper limit of normal (ULN). An independent chemistry laboratory evaluated all collected blood samples. Results: Post-procedural CK sampling was available in 1629 of 1800 patients (90.5%). As per protocol, CK-MB analyses were undertaken in 474 of 491 patients (96.5%) in the CABG arm, and 53 of 61 patients (86.9%) in the PCI arm. Within the CABG arm, despite the limitations of incomplete data, a post-procedural CK-MB ratio <3/>= 3 ULNseparated 4-year mortality into low-and high-risk groups (2.3% vs. 9.5%, p = 0.03). Additionally, in the CABG arm, a post-procedural CK-MB ratio = 3 ULN was associated with an increased frequency of a high SYNTAX Score (= 33) tertile (high [>= 33] SYNTAX Score: 39.5%, intermediate [23-32] SYNTAX Score 31.0%, low [>= 22] SYNTAX Score 29.5%, p = 0.02). Within the PCI arm, a post-procedural CK ratio of >2 or >= 2 ULN separated 4-year mortality into low-and high-risk groups (10.8% vs. 23.3%, p = 0.001). Notably, there was an early (within 6 months) and late (after 2 years) peak in mortality in patients with a post-PCI CK ratio of = 2 ULN. Lack of pre-procedural thienopyridine, carotid artery disease, type 1 diabetes, andpresenceof coronary bifurcationswere independent correlates of a CK ratio = 2 ULNpost-PCI. Conclusion: Cardiac enzyme elevations post-CABG or post-PCI are associatedwith an adverse long-termmortality; the causes of which are multifactorial.

- Background The residual Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery (SYNTAX) Score is an objective measure of the degree and complexity of residual stenosis after percutaneous coronary intervention (PCI). Methods and Results In the randomized PCI cohort of the SYNTAX Trial (n=903), the baseline and residual SYNTAX Scores were calculated. Subjects with a residual SYNTAX Score of 0 were defined as having undergone complete revascularization (CR), and a residual SYNTAX Score >0 as incomplete revascularization (ICR). Five-year clinical outcomes were stratified by CR and ICR (tertiles of the residual SYNTAX Score: >0-4, >4-8, and >8). In the PCI cohort, the mean baseline and residual SYNTAX Scores were 28.4 +/- 11.5 and 4.5 +/- 6.9, respectively. The mean SYNTAX Score (representative of the burden of disease removed by PCI) was 23.8 +/- 10.9. The residual SYNTAX Score was distributed as follows: CR, 0 (n=386, 42.7%); ICR, >0 to 4 (n=184, 20.4%), >4 to 8 (n=167, 18.5%), >8 (n=153, 16.9%). A progressively higher residual SYNTAX Score was shown to be a surrogate marker of increasing clinical comorbidity and anatomic complexity. Subjects with CR or residual SYNTAX Scores 8 had comparable 5-year mortality (CR, 8.5%; residual SYNTAX Score >0-4, 8.7%; >4-8, 11.4%; P=0.60). A residual SYNTAX Score >8 was associated with 35.3% all-cause mortality at 5-years (P<0.001). Stratified analyses in the predefined medical treated diabetic and left main subgroups yielded similar results. Conclusions The residual SYNTAX Score was shown to be a powerful indicator of 5-year mortality in the SYNTAX Trial. The residual SYNTAX Score may aid in determining a reasonable level of revascularization.

- Objectives The aim of this study was to report the short-term and long-term clinical impact of stent thrombosis (ST) and graft occlusion (GO) in the final 5-year outcomes of the SYNTAX (SYNergy Between PCI With TAXUS and Cardiac Surgery) trial.Background The clinical effect of newer-generation drug-eluting stents and operative factors in complex coronary artery disease is uncertain.Methods The incidence of 5-year ST and GO, and their association with clinical outcomes, were analyzed in the randomized percutaneous coronary intervention and coronary artery bypass graft cohorts. ST and GO were defined by the SYNTAX protocol definitions (clinical presentation with acute coronary syndrome and angiographic/pathological evidence), the Academic Research Consortium (ARC) definition for ST, and the newly devised "ARC-like" definition of GO (i.e., definite, probable, or possible GO).Results At 5 years, 871 of 903 patients (96.5%) in the percutaneous coronary intervention cohort and 805 of 897 patients (89.7%) in the coronary artery bypass graft cohort completed follow-up. As compared with other vessel locations, protocol ST (72 lesions) occurred more frequently in the left main (14 of 72; 19%) and proximal coronary vasculature (37 of 72; 51%) and protocol GO (41 lesions) with grafts anastomosed to the distal right coronary artery (17 of 41; 42%). The incidence of 5-year ARC definite ST and ARC-like definite GO did not significantly differ (7%[n = 48] vs. 6% [n = 32], log rank p = 0.34); landmark analyses indicated significantly increased ARC definite ST within 30 days (3% [n = 19] vs. 1% [n = 6], log rank p = 0.033) but not >30 days to 5 years (4.2% [n = 29] vs. 4.5% [n = 26], log rank p = 0.78). At presentation, ARC definite ST (n = 48) and ARC-like definite GO (n = 32) were adjudicated to be linked to 4 (8%) and 0 deaths, respectively. At 5 years, ARC definite ST (n = 48) and ARC definite/probable ST (n = 75) were associated with 17 (17 of 48, 35.4%; median days to death: 0 days; interquartile range: 0 to 16 days; maximum: 321 days) and 31 (31 of 75, 41.3%; median: 0 days; interquartile range: 0 to 9 days; maximum: 721 days) cardiac deaths, respectively. At 5 years, ARC-like definite GO (n = 32) and ARC-like definite/probable GO (n = 53) were associated with 0 and 12 (12 of 52, 23.1%; median: 0 days; interquartile range: 0 to 14 days; maximum: 257 days) cardiac deaths, respectively.Conclusions Although the incidence of ST and GO was similar at 5 years, the clinical impact of ST appeared greater, with a negative impact on short-term to long-term mortality.

- AIMS: The SYNTAX Score (SXscore) has established itself as an important prognostic tool in patients undergoing percutaneous coronary intervention (PCI). A limitation of the SXscore is the inability to differentiate outcomes in patients who have undergone prior coronary artery bypass graft (CABG) surgery. The CABG SXscore was devised to address this limitation.METHODS AND RESULTS: In the SYNTAX-LE MANS substudy 115 patients with unprotected left main coronary artery disease (isolated or associated with one, two or three-vessel disease) treated with CABG were prospectively assigned to undergo a 15-month coronary angiogram. An independent core laboratory analysed the baseline SXscore prior to CABG. The 15-month CABG SXscore was calculated by a panel of three interventional cardiologists. The CABG SXscore was calculated by determining the standard SXscore in the "native" coronary vessels ("native SXscore") and deducting points based on the importance of the diseased coronary artery segment (Leaman score) that have a functioning bypass graft anastomosed distally. Points relating to intrinsic coronary disease, such as bifurcation disease or calcification, remain unaltered. The mean 15-month CABG SXscore was significantly lower compared to the mean baseline SXscore (baseline SXscore 31.6, SD 13.1; 15-month CABG SXscore 21.2, SD 11.1; p<0.001). Reproducibility analyses (kappa [k] statistics) indicated a substantial agreement between CABG SXscore measurements (k=0.70; 95% CI [0.50-0.90], p<0.001), with the points deducted to calculate the CABG SXscore the most reproducible measurement (k=0.74; 95% CI [0.53-0.95], p<0.001). Despite the limited power of the study, four-year outcome data (Kaplan-Meier curves) demonstrated a trend towards reduced all-cause death (9.1% vs. 1.8%, p=0.084) and death/CVA/MI (16.4% vs. 7.0%, p=0.126) in the low compared to the high CABG SXscore group.CONCLUSIONS: In this pilot study the calculation of the CABG SXscore appeared feasible, reproducible and may have a long-term prognostic role in patients with complex coronary disease undergoing surgical revascularisation. Validation of this new scoring methodology is required.

- OBJECTIVES:The study sought to evaluate the clinical impact of angiographic complete (CR) and incomplete (ICR) revascularization and its association with the presence of total occlusions (TO), after percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery in the "all-comers" SYNTAX (Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) trial.BACKGROUND:In patients with complex coronary artery disease undergoing PCI or CABG, the long-term prognostic implications of CR versus ICR is unsettled.METHODS:In this post hoc study, consisting of randomized (n = 1,800) and nested PCI (n = 198) and CABG (n = 649) registries, 4-year clinical outcomes were compared in groups, with and without angiographic CR, in the PCI and CABG arms. Clinical outcomes were analyzed with Kaplan-Meier estimates, log-rank comparisons, and Cox regression analyses. Multivariate predictors of ICR were determined. Similar analyses were undertaken in the TO and non-TO treated groups of both study arms.RESULTS:Angiographic CR was achieved in 52.8% of the PCI arm and 66.9% of the CABG arm. Within the PCI and CABG arms, ICR (compared with CR) seemed to be a surrogate marker of a greater burden of anatomical coronary complexity and clinical comorbidity and was associated with significantly higher frequencies of 4-year mortality, all-cause revascularization, stent thrombosis (PCI arm), and major adverse cardiac and cerebrovascular events. The presence of a TO was the strongest independent predictor of ICR after PCI (hazard ratio: 2.70, 95% confidence interval: 1.98 to 3.67, p < 0.001). Eight hundred and forty patients (PCI: 26.3%, CABG: 36.4%, p < 0.001) were identified to have 1,007 TOs, with 68.1% of TOs located in the proximal-mid coronary vasculature. The findings associating ICR (compared with CR) with higher frequencies of 4-year mortality and major adverse cardiac and cerebrovascular events remained consistent in the TO-treated groups in the PCI and CABG arms.CONCLUSIONS:Within the PCI and CABG arms of the all-comers SYNTAX trial, angiographically determined ICR has a detrimental impact on long-term clinical outcomes, including mortality. This effect remained consistent in patients with and without TOs.

- It is unclear whether coronary artery bypass grafting (CABG) improves survival compared with medical therapy (MT) in patients with stable coronary artery disease (CAD). The aim of this analysis was to perform an individual-patient data-pooled meta-analysis of contemporary randomized controlled trials that compared CABG and MT in patients with stable CAD.A systematic search was performed in January 2021 to identify randomized controlled trials enrolling adult patients with stable CAD, randomized to CABG or MT. Only trials using at least aspirin, beta-blockers, and statins in the MT arm were included. Individual patient data were obtained from all eligible studies and pooled. The primary outcome was all-cause mortality.Four trials involving 2523 patients (1261 CABG; 1262MT) were included with a median follow-up of 5.6 (4.0-9.2) years. CABG was associated with increased risk of all-cause mortality within 30days (hazard ratio [HR], 4.81; 95% confidence interval [CI], 1.95-11.83) but subsequent reduction in the long-term risk of death (HR, 0.79; 95% CI, 0.69-0.89). As such, the cumulative 10-year mortality rate was lower in patients treated with CABG compared with MT (45.1% vs 51.7%, respectively; odds ratio, 0.70; 95% CI, 0.58-0.85). Age and race were significant treatment effect modifier (interaction P=.003 for both).In patients with stable CAD, initial allocation to CABG was associated with greater periprocedural risk of death but improved long-term survival compared with MT. The survival advantage for CABG became significant after the fourth postoperative year and was particularly pronounced in younger and non-White patients.

- 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.

- Aims: Long-term randomized comparisons of percutaneous coronary intervention (PCI) to coronary artery bypass grafting (CABG) in left main coronary (LM) disease and/or three-vessel disease (3VD) patients have been limited. This analysis compares 3-year outcomes in LM and/or 3VD patients treated with CABG or PCI with TAXUS Express stents. Methods and results: SYNTAX is an 85-centre randomized clinical trial (n = 1800). Prospectively screened, consecutive LM and/or 3VD patients were randomized if amenable to equivalent revascularization using either technique; if not, they were entered into a registry. Patients in the randomized cohort will continue to be followed for 5 years. At 3 years, major adverse cardiac and cerebrovascular events [MACCE: death, stroke, myocardial infarction (MI), and repeat revascularization; CABG 20.2% vs. PCI 28.0%, P < 0.001], repeat revascularization (10.7 vs. 19.7%, P < 0.001), and MI (3.6 vs. 7.1%, P = 0.002) were elevated in the PCI arm. Rates of the composite safety endpoint (death/stroke/MI 12.0 vs. 14.1%, P = 0.21) and stroke alone (3.4 vs. 2.0%, P = 0.07) were not significantly different between treatment groups. Major adverse cardiac and cerebrovascular event rates were not significantly different between arms in the LM subgroup (22.3 vs. 26.8%, P = 0.20) but were higher with PCI in the 3VD subgroup (18.8 vs. 28.8%, P < 0.001). Conclusions: At 3 years, MACCE was significantly higher in PCI-compared with CABG-treated patients. In patients with less complex disease (low SYNTAX scores for 3VD or low/intermediate terciles for LM patients), PCI is an acceptable revascularization, although longer follow-up is needed to evaluate these two revascularization strategies.

- Aims: Coronary artery bypass graft (CABG) surgery is the standard of care for revascularisation of patients with left main coronary artery disease (LMCAD). Recent studies have suggested that percutaneous coronary intervention (PCI) with drug-eluting stents (DES) may provide comparable outcomes in selected patients with LMCAD without extensive CAD. We therefore designed a trial to investigate whether PCI with XIENCE cobalt-chromium everolimus-eluting stents (CoCr-EES) would result in non-inferior or superior clinical outcomes to CABG in selected patients with LMCAD. Methods and results: The Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization (EXCEL) trial is a prospective, open-label, multicentre, international study of 1,900 randomised subjects. Patients with significant LMCAD with a SYNTAX score <= 32 and local Heart Team consensus that the subject is appropriate for revascularisation by both PCI and CABG are consented and randomised 1:1 to undergo PCI using CoCr-EES or CABG. All patients undergo follow-up for five years. The primary endpoint is the three-year composite rate of death, stroke or myocardial infarction, assessed at a median follow-up of at least three years (with at least two-year follow-up in all patients), powered for sequential non-inferiority and superiority testing. Conclusions: The EXCEL study will define the contemporary roles of CABG and PCI using XIENCE CoCr-EES in patients with LMCAD disease with low and intermediate SYNTAX scores.

- Background Use of the modified American College of Cardiology (ACC)/American Heart Association (AHA) lesion classification as a prognostic tool to predict short- and long-term clinical outcomes after percutaneous coronary intervention in the modern drug-eluting stent era is uncertain. Methods and Results Patient-level data from 7 prospective, randomized trials were pooled. Clinical outcomes of patients undergoing single lesion percutaneous coronary intervention with second-generation drug-eluting stent were analyzed according to modified ACC/AHA lesion class. The primary end point was target lesion failure (TLF: composite of cardiac death, target vessel myocardial infarction, or ischemia-driven target lesion revascularization). Clinical outcomes to 5 years were compared between patients treated for noncomplex (class A/B1) versus complex (class B2/C) lesions. Eight thousand five hundred sixteen patients (age 63.1±10.8 years, 70.5% male) were analyzed. Lesions were classified as A, B1, B2, and C in 7.9%, 28.5%, 33.7%, and 30.0% of cases, respectively. Target lesion failure was higher in patients undergoing percutaneous coronary intervention of complex versus noncomplex lesions at 30 days (2.0% versus 1.1%, P=0.004), at 1 year (4.6% versus 3.0%, P=0.0005), and at 5 years (12.4% versus 9.2%, P=0.0001). By multivariable analysis, treatment of ACC/AHA class B2/C lesions was significantly associated with higher rate of 5-year target lesion failure (adjusted hazard ratio, 1.39 [95% CI, 1.17-1.64], P=0.0001) driven by significantly higher rates of target vessel myocardial infarction and ischemia-driven target lesion revascularization. Conclusions In this pooled large-scale analysis, treating complex compared with noncomplex lesions according to the modified ACC/AHA classification with second-generation drug-eluting stent was associated with worse 5-year clinical outcomes. This historical classification system may be useful in the contemporary era for predicting early and late outcomes following percutaneous coronary intervention.

- OBJECTIVES: This study sought to analyze stroke rates in the SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) trial's randomized and registry cohorts of patients being treated with coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) for treatment of complex coronary artery disease.BACKGROUND: The SYNTAX trial compared PCI to CABG in patients with de novo 3-vessel and/or left main coronary disease.METHODS: The SYNTAX randomized trial was conducted at 85 U.S. and European sites (n = 1,800). All strokes (up to 4 years) were independently adjudicated by a clinical events committee that included a neurologist. An additional 1,077 (of which 644 were followed for 5 years) and 198 patients were included in the CABG and PCI registries, respectively.RESULTS: In the randomized cohort, 31 CABG and 19 PCI patients experienced 33 and 20 strokes post-randomization at 4-year follow-up, respectively (p = 0.062). Three strokes occurred pre-procedurally but following randomization in CABG-treated patients. After CABG, a large proportion of strokes occurred acutely (0 to 30 days: 9 of 33), whereas in the PCI arm, most strokes occurred >30 days after the procedure (18 of 20). Stroke resulted in death in 3 patients in both the PCI and CABG groups. Of the patients who developed stroke, 68% (21 of 31) in the CABG group had residual deficits at discharge; in the PCI group, 47% (9 of 19) had residual deficits. In a multivariate analysis, treatment with CABG was not significantly associated with increased stroke rates (odds ratio: 1.67, 95% confidence interval: 0.93 to 3.01, p = 0.089). The incidence and outcomes of stroke were similar in the randomized trial and registries.CONCLUSIONS: There is a higher risk of periprocedural stroke in patients undergoing CABG versus PCI; however, the risk converges over the first 4 years of follow-up.

- 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.

- 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.
