RESUMO
BACKGROUND: Although target lesion revascularization (TLR) after percutaneous coronary intervention (PCI) for unprotected left main coronary artery (LMCA) disease is not rare, its timing of occurrence and prognostic impact on long-term mortality is uncertain. OBJECTIVES: This study sought to investigate TLR incidence over time and its impact on mortality after PCI with drug-eluting stents (DES) for LMCA disease. METHODS: Using a pooled data from 4 multicenter observational registries (IRIS-DES [Interventional Cardiology Research Incorporation Society-Drug-Eluting Stents], IRIS-MAIN [Interventional Cardiology Research Incorporation Society-Left MAIN Revascularization], MAIN-COMPARE [Revascularization for Unprotected Left Main Coronary Artery Stenosis: Comparison of Percutaneous Coronary Angioplasty Versus Surgical Revascularization], and PRECOMBAT [PREmier of Randomized COMparison of Bypass Surgery versus AngioplasTy Using Drug-Eluting Stent in Patients with Left Main Coronary Artery Disease]), we evaluated 1,397 patients with LMCA disease treated with DES and available long-term mortality data. The association between TLR and the 10-year risk of mortality was examined by multivariable Cox proportional hazards regression, with TLR as a time-varying covariate. RESULTS: During maximum follow-up of 10 years (median 6.8 years), TLR occurred in 118 patients and its 10-year cumulative incidence was 10.8%. TLR mostly occurred within 2 years after initial PCI and decreased over time: early-stage TLR (within 2 years) in 73 (61.9%) patients and late-stage TLR (beyond 2 years) in 45 (38.1%) patients. Among all TLR patients, 23 patients underwent coronary artery bypass grafting and 95 underwent repeat PCI. In the time-varying multivariable Cox model, the presence of TLR was not significantly associated with an increased risk of mortality (adjusted HR: 0.90; 95% CI: 0.50-1.63; P = 0.73). CONCLUSIONS: Although the incidence of ischemia-driven TLR was mostly common within 2 years after left main PCI, TLR occurred steadily during the 10-year follow-up period. However, given that such patients were optimally revascularized, the prognostic impact of TLR on mortality was not substantial.

OBJECTIVE: To compare the clinical outcomes of aortic valve replacement (AVR) using bovine pericardial and porcine bioprostheses, utilizing a nationwide administrative claims database. METHODS: Adult patients (age ≥40 years) who underwent bioprosthetic AVR, without other valve replacements, between 2003 and 2018 were identified from the Korean National Health Insurance Service database. The outcomes of interest were all-cause mortality, cardiac mortality, and valve-related events, including the incidence of reoperation, endocarditis, systemic thromboembolism, and major bleeding. Baseline adjustment was performed using propensity score matching. Time-related outcomes were evaluated using a competing risk analysis, with death as a competing risk. RESULTS: Among the 7714 patients who underwent bioprosthetic AVR, 5621 (72.9%) received bovine pericardial prostheses and 2093 (27.1%) received porcine bioprostheses. After matching, 1937 pairs were included in the final analysis. During follow-up (median, 4.49 years; interquartile range, 2.83-8.20 years), the use of porcine bioprostheses was associated with a higher risk of aortic valve reoperation (adjusted hazard ratio [HR], 1.87; 95% confidence interval [CI], 1.16 to 3.01); however, no significant differences were observed in cumulative incidences of all-cause mortality, cardiac mortality, thromboembolism, or major bleeding. Subgroup analyses revealed that the use of bovine valves was associated with improved survival in patients with diabetes mellitus, whereas in patients undergoing dialysis, porcine valves exhibited better survival than bovine valves. CONCLUSIONS: In this large nationwide cohort study of patients undergoing bioprosthetic aortic valve replacement, the use of porcine prostheses was significantly associated with an increased risk of reoperation compared with the use of bovine prostheses, supporting previous findings.
RESUMO
BACKGROUND: Diabetes mellitus is associated with more complex coronary artery diseases. Coronary artery bypass grafting (CABG) is a preferred revascularization strategy over percutaneous coronary intervention (PCI) in diabetics with multivessel coronary artery disease (MVD). OBJECTIVES: This study sought to examine the different prognostic effects of revascularization strategies according to the diabetes status from the randomized BEST (Randomized Comparison of Coronary Artery Bypass Surgery and Everolimus-Eluting Stent Implantation in the Treatment of Patients With Multivessel Coronary Artery Disease) trial. METHODS: Patients (n = 880) with MVD were randomly assigned to undergo PCI with an everolimus-eluting stent vs CABG stratified by diabetics (n = 363) and nondiabetics (n = 517). The primary endpoint was the composite of death, myocardial infarction, or target vessel revascularization during a median follow-up of 11.8 years (IQR: 10.6-12.5 years). RESULTS: In diabetics, the primary endpoint rate was significantly higher in the PCI group than in the CABG group (43% and 32%; HR: 1.53; 95% CI: 1.12-2.08; P = 0.008). However, in nondiabetics, no significant difference was found between the groups (PCI group, 29%; CABG group, 29%; HR: 0.97; 95% CI: 0.67-1.39; P = 0.86; Pinteraction= 0.009). Irrespective of the presence of diabetes, no significant between-group differences were found in the rate of a safety composite of death, myocardial infarction, or stroke and mortality rate. However, the rate of any repeat revascularization was significantly higher in the PCI group than in the CABG group. CONCLUSIONS: In diabetics with MVD, CABG was associated with better clinical outcomes than PCI. However, the mortality rate was similar between PCI and CABG irrespective of diabetes status during an extended follow-up.

It is unknown whether there are age- and gender-related differences in the safety and efficacy of potent P2Y12 inhibitors in East Asian populations with a different bleeding or ischemic propensity. Using data from the TICAKOREA (Ticagrelor Versus Clopidogrel in Asian/Korean Patients with ACS Intended for Invasive Management) trial comparing ticagrelor versus clopidogrel for 800 Korean patients with acute coronary syndrome, the safety and efficacy outcomes were compared according to age (<75 vs ≥75 years) and gender (men vs women). The primary bleeding end point was clinically significant bleeding, and the primary ischemic end point was a major adverse cardiovascular event (MACE) at 12 months. The incidences of clinically significant bleeding were significantly higher after ticagrelor than after clopidogrel in patients aged <75 years (adjusted hazard ratio [HR] 2.56, 95% confidence interval [CI] 1.40 to 4.67) but not in patients aged ≥75 years (adjusted HR 1.1, 95% CI 0.40 to 3.38). The incidences of MACEs were significantly higher after ticagrelor than after clopidogrel in patients aged ≥75 years (adjusted HR 6.14, 95% CI 1.40 to 26.90) but not in patients aged <75 years (adjusted HR 0.93, 95% CI 0.50 to 1.73). The incidences of clinically significant bleeding were significantly higher after ticagrelor than after clopidogrel in men (adjusted HR 2.69, 95% CI 1.38 to 5.24) but not in women (adjusted HR 1.49, 95% CI 0.64 to 3.46). The adjusted risks of MACEs after ticagrelor or clopidogrel were not significantly different between men and women. In conclusion, there were substantial age- and gender-related differences in bleeding and ischemic outcomes after ticagrelor or clopidogrel in Korean patients with acute coronary syndrome.

Although optimal medical therapy (OMT) after coronary revascularization is advocated for intensive secondary prevention, its criteria and effect on long-term outcomes are uncertain. Using data from the ASAN-Multivessel (Asan Medical Center-Multivessel Revascularization) registry, we identified 8,311 patients who underwent coronary artery bypass grafting (CABG) (n = 3,115) or percutaneous coronary intervention (PCI) (n = 5,196). OMT was defined as the combination of minimum of 3 medications in 4 drug classes (antiplatelet drugs, statins, ß blockers, and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers). Two primary outcomes were all-cause mortality and serious composite outcome of death, spontaneous myocardial infarction, or stroke at 10 years. Of 8,311 patients, 4,321 (52.0%) followed OMT. In the 3,397 propensity-score-matched cohort, OMT status compared with non-OMT status was significantly associated with a lower risk of all-cause mortality (10.7% vs 18.7%; hazard ratio [HR] 0.55, 95% confidence interval [CI] 0.47 to 0.65) and serious composite outcome (14.5% vs 22.5%, HR 0.635, 95% CI 0.55 to 0.73) at 10 years. The association on 10-year mortality was more prominent in the PCI group (HR 0.45, 95% CI 0.36 to 0.56) than in the CABG group (HR 0.72, 95% CI 0.58 to 0.90) with a significant interaction (p = 0.001). Overall findings were consistent using different OMT criteria (all 4 types of medications). In conclusion, OMT significantly lowered the risks of mortality and major cardiovascular events at 10 years in patients with multivessel revascularization. The OMT impact on mortality was more remarkable in the PCI group than in the CABG group. This work was registered at http://ClinicalTrials.gov (Identifier: NCT02039752).

BACKGROUND: Cardiac allograft vasculopathy (CAV) is a major obstacle limiting long-term graft survival. Effective noninvasive surveillance modalities reflecting both coronary artery and microvascular components of CAV are needed. OBJECTIVES: The authors evaluated the diagnostic performance of dynamic computed tomography-myocardial perfusion imaging (CT-MPI) and coronary computed tomography angiography (CCTA) for CAV. METHODS: A total of 63 heart transplantation patients underwent combined CT-MPI and CCTA plus invasive coronary angiography (ICA) with intravascular ultrasonography (IVUS) between December 2018 and October 2021. The median interval between CT-MPI and heart transplantation was 4.3 years. Peak myocardial blood flow (MBF) of the whole myocardium (MBFglobal) and minimum MBF (MBFmin) among the 16 segments according to the American Heart Association model, except the left ventricular apex, were calculated from CT-MPI. CCTA was assessed qualitatively, and the degree of coronary artery stenosis was recorded. CAV was diagnosed based on both ICA (ISHLT criteria) and IVUS. Patients were followed up for a median time of 2.3 years after CT-MPI and a median time of 5.7 years after transplantation. RESULTS: Among the 63 recipients, 35 (55.6%) had diagnoses of CAV. The median MBFglobal and MBFmin were significantly lower in patients with CAV (128.7 vs 150.4 mL/100 mL/min; P = 0.014; and 96.9 vs 122.8 mL/100 mL/min; P < 0.001, respectively). The combined use of coronary artery stenosis on CCTA and MBFmin showed the highest diagnostic performance with an area under the curve of 0.886 (sensitivity: 74.3%, specificity: 96.4%, positive predictive value: 96.3%, and negative predictive value: 75.0%). CONCLUSIONS: The combination of CT-MPI and CCTA demonstrated excellent diagnostic performance for the detection of CAV. One-stop evaluation of the coronary artery and microvascular components involved in CAV using combined CCTA and CT-MPI may be a potent noninvasive screening method for early detection of CAV.

Importance: Although a patient's age may be the only objective figure that can be used as a reference indicator in selecting the type of prosthesis in heart valve surgery, different clinical guidelines use different age criteria. Objective: To explore the age-associated survival-hazard functions associated with prosthesis type in aortic valve replacement (AVR) and mitral valve replacement (MVR). Design, Setting, and Participants: This cohort study compared the long-term outcomes associated with mechanical and biologic prostheses in AVR and MVR according to recipient's age using a nationwide administrative data from the Korean National Health Insurance Service. To reduce the potential treatment-selection bias between mechanical and biologic prostheses, the inverse-probability-of-treatment-weighting method was used. Participants included patients who underwent AVR or MVR in Korea between 2003 and 2018. Statistical analysis was performed between March 2022 and March 2023. Exposures: AVR, MVR, or both AVR and MVR with mechanical or biologic prosthesis. Main Outcomes and Measures: The primary end point was all-cause mortality after receiving prosthetic valves. The secondary end points were the valve-related events, including the incidence of reoperation, systemic thromboembolism, and major bleeding. Results: Of the total of 24â¯347 patients (mean [SD] age, 62.5 [7.3] years; 11â¯947 [49.1%] men) included in this study, 11â¯993 received AVR, 8911 received MVR, and 3470 received both AVR and MVR simultaneously. Following AVR, bioprosthesis was associated with significantly greater risks of mortality than mechanical prosthesis in patients younger than 55 years (adjusted hazard ratio [aHR], 2.18; 95% CI, 1.32-3.63; P = .002) and in those aged 55 to 64 years (aHR, 1.29; 95% CI, 1.02-1.63; P = .04), but the risk of mortality reversed in patients aged 65 years or older (aHR, 0.77; 95% CI, 0.66-0.90; P = .001). For MVR, the risk of mortality was also greater with bioprosthesis in patients aged 55 to 69 years (aHR, 1.22; 95% CI, 1.04-1.44; P = .02), but there was no difference for patients aged 70 years or older (aHR, 1.06; 95% CI, 0.79-1.42; P = .69). The risk of reoperation was consistently higher with bioprosthesis, regardless of valve position, in all age strata (eg, MVR among patients aged 55-69 years: aHR, 7.75; 95% CI, 5.14-11.69; P < .001); however, the risks of thromboembolism and bleeding were higher in patients aged 65 years and older after mechanical AVR (thromboembolism: aHR, 0.55; 95% CI, 0.41-0.73; P < .001; bleeding: aHR, 0.39; 95% CI, 0.25-0.60; P < .001), with no differences after MVR in any age strata. Conclusions and Relevance: In this nationwide cohort study, the long-term survival benefit associated with mechanical prosthesis vs bioprosthesis persisted until age 65 years in AVR and age 70 years in MVR.

OBJECTIVES: Comparisons of long-term clinical outcomes of mitral valve replacement (MVR) between bovine pericardial and porcine bioprostheses are conflicting, with limited research in large-scale real-world clinical settings. This study examined clinical outcomes in MVR according to bioprosthesis type using a national administrative claims database. METHODS: This study included adult patients undergoing bioprosthetic MVR between 2003 and 2018 using administrative health care data from the Korean National Health Insurance Service database. Propensity score matching with competing risk analysis was used to compare the clinical outcomes according to the type of bioprosthesis. The end points were death, cardiac death, and valve-related events, including the incidence of reoperation, endocarditis, systemic thromboembolism, and major bleeding. RESULTS: A total of 3151 patients underwent bioprosthetic MVR with bovine pericardial (n = 1628, 51.7%) or porcine (n = 1523, 48.3%) bioprostheses. After matching, 1170 pairs were included in the final analysis. During follow-up (median 4.49 years, interquartile range 1.87 -8.75 years), death occurred in 1178 patients (6.8%/patient-year), comprising 730 (4.3%/patient-year) cardiac death. No significant differences were noted between the bovine and porcine groups in the cumulative incidences of death from any cause [adjusted hazard ratio (aHR), 1.00; 95% confidence interval (CI), 0.87-1.14], cardiac mortality (aHR, 0.96; 95% CI, 0.81-1.14), or reoperation (aHR, 1.01; 95% CI, 0.72-1.41). CONCLUSIONS: This study on a nationwide comparison between bovine and porcine bioprostheses in MVR found no significant differences in clinical outcomes including mortality, and valve-related reoperation.

Background: Whether complete revascularization (CR) or incomplete revascularization (IR) may affect long-term outcomes after PCI) and coronary artery bypass grafting (CABG) for left main coronary artery (LMCA) disease is unclear. Objectives: The authors sought to assess the impact of CR or IR on 10-year outcomes after PCI or CABG for LMCA disease. Methods: In the PRECOMBAT (Premier of Randomized Comparison of Bypass Surgery versus Angioplasty Using Sirolimus-Eluting Stent in Patients with Left Main Coronary Artery Disease) 10-year extended study, the authors evaluated the effect of PCI and CABG on long-term outcomes according to completeness of revascularization. The primary outcome was the incidence of major adverse cardiac or cerebrovascular events (MACCE) (composite of mortality from any cause, myocardial infarction, stroke, or ischemia-driven target vessel revascularization). Results: Among 600 randomized patients (PCI, n = 300 and CABG, n = 300), 416 patients (69.3%) had CR and 184 (30.7%) had IR; 68.3% of PCI patients and 70.3% of CABG patients underwent CR, respectively. The 10-year MACCE rates were not significantly different between PCI and CABG among patients with CR (27.8% vs 25.1%, respectively; adjusted HR: 1.19; 95% CI: 0.81-1.73) and among those with IR (31.6% vs 21.3%, respectively; adjusted HR: 1.64; 95% CI: 0.92-2.92) (P for interaction = 0.35). There was also no significant interaction between the status of CR and the relative effect of PCI and CABG on all-cause mortality, serious composite of death, myocardial infarction, or stroke, and repeat revascularization. Conclusions: In this 10-year follow-up of PRECOMBAT, the authors found no significant difference between PCI and CABG in the rates of MACCE and all-cause mortality according to CR or IR status.

RESUMO
Background: Female subjects have poorer outcomes in left main coronary artery (LMCA) disease compared with male subjects. However, limited information is available on the long-term prognostic impact of sex and sex-treatment interactions in patients with LMCA disease undergoing coronary revascularization. Objectives: The goal of this study was to investigate the long-term effects of sex and related differential outcomes after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in LMCA disease. Methods: The extended PRECOMBAT (Premier of Randomized Comparison of Bypass Surgery versus Angioplasty Using Sirolimus-Eluting Stent in Patients with Left Main Coronary Artery Disease) trial evaluated the >10-year clinical outcomes in patients with LMCA disease randomized to undergo PCI with drug-eluting stents (n = 300) or CABG (n = 300). The primary outcome was major adverse cardiac or cerebrovascular events (MACCE) (composite of death, myocardial infarction, stroke, or ischemia-driven target vessel revascularization) at 10 years. Results: Of the 600 patients, 459 (76.5%) were male. The 10-year rates of MACCE were similar between male and female subjects in the overall cohort (27.3% vs 27.0%; adjusted hazard ratio [aHR]: 1.06; 95% confidence interval [CI]: 0.70-1.59), the PCI arm (30.6% vs 27.1%; aHR: 1.19; 95% CI: 0.69-2.05), and the CABG arm (24.0% vs 26.9%; aHR: 0.93; 95% CI: 0.53-1.62). The 10-year risks for MACCE did not significantly differ between PCI and CABG in both male (aHR: 1.37; 95% CI: 0.95-1.97) and female (aHR: 1.07; 95% CI: 0.56-2.07) subjects. There was no significant sex-treatment interaction regarding the adjusted risk of MACCE at 10 years (P for interaction = 0.52). Conclusions: In this 10-year follow-up of the PRECOMBAT trial, there was no sex-related impact on the long-term risk of MACCE after PCI and CABG for LMCA disease.

BACKGROUND: Long-term comparative outcomes after percutaneous coronary intervention (PCI) with everolimus-eluting stents and coronary artery bypass grafting (CABG) are limited in patients with multivessel coronary artery disease. METHODS: This prospective, multicenter, randomized controlled trial was conducted in 27 international heart centers and was designed to randomly assign 1776 patients with angiographic multivessel coronary artery disease to receive PCI with everolimus-eluting stents or CABG. After inclusion of 880 patients (438 in the PCI group and 442 in the CABG group) between July 2008 and September 2013, the study was terminated early because of slow enrollment. The primary end point was the composite of death from any cause, myocardial infarction, or target vessel revascularization. RESULTS: During a median follow-up of 11.8 years (interquartile range, 10.6-12.5 years; maximum, 13.7 years), the primary end point occurred in 151 patients (34.5%) in the PCI group and 134 patients (30.3%) in the CABG group (hazard ratio [HR], 1.18 [95% CI, 0.88-1.56]; P=0.26). No significant differences were seen in the occurrence of a safety composite of death, myocardial infarction, or stroke between groups (28.8% and 27.1%; HR, 1.07 [95% CI, 0.75-1.53]; P=0.70), as well as the occurrence of death from any cause (20.5% and 19.9%; HR, 1.04 [95% CI, 0.65-1.67]; P=0.86). However, spontaneous myocardial infarction (7.1% and 3.8%; HR, 1.86 [95% CI, 1.06-3.27]; P=0.031) and any repeat revascularization (22.6% and 12.7%; HR, 1.92 [95% CI, 1.58-2.32]; P<0.001) were more frequent after PCI than after CABG. CONCLUSIONS: In patients with multivessel coronary artery disease, there were no significant differences between PCI and CABG in the incidence of major adverse cardiac events, the safety composite end point, and all-cause mortality during the extended follow-up.

BACKGROUND: There are limited data from randomized trials to guide a specific follow-up surveillance approach after myocardial revascularization. Whether a follow-up strategy that includes routine functional testing improves clinical outcomes among high-risk patients who have undergone percutaneous coronary intervention (PCI) is uncertain. METHODS: We randomly assigned 1706 patients with high-risk anatomical or clinical characteristics who had undergone PCI to a follow-up strategy of routine functional testing (nuclear stress testing, exercise electrocardiography, or stress echocardiography) at 1 year after PCI or to standard care alone. The primary outcome was a composite of death from any cause, myocardial infarction, or hospitalization for unstable angina at 2 years. Key secondary outcomes included invasive coronary angiography and repeat revascularization. RESULTS: The mean age of the patients was 64.7 years, 21.0% had left main disease, 43.5% had bifurcation disease, 69.8% had multivessel disease, 70.1% had diffuse long lesions, 38.7% had diabetes, and 96.4% had been treated with drug-eluting stents. At 2 years, a primary-outcome event had occurred in 46 of 849 patients (Kaplan-Meier estimate, 5.5%) in the functional-testing group and in 51 of 857 (Kaplan-Meier estimate, 6.0%) in the standard-care group (hazard ratio, 0.90; 95% confidence interval [CI], 0.61 to 1.35; P = 0.62). There were no between-group differences with respect to the components of the primary outcome. At 2 years, 12.3% of the patients in the functional-testing group and 9.3% in the standard-care group had undergone invasive coronary angiography (difference, 2.99 percentage points; 95% CI, -0.01 to 5.99), and 8.1% and 5.8% of patients, respectively, had undergone repeat revascularization (difference, 2.23 percentage points; 95% CI, -0.22 to 4.68). CONCLUSIONS: Among high-risk patients who had undergone PCI, a follow-up strategy of routine functional testing, as compared with standard care alone, did not improve clinical outcomes at 2 years.

BACKGROUND: Although there is a growing interest in prediction models based on electronic medical records (EMRs) to identify patients at risk of adverse cardiac events following invasive coronary treatment, robust models fully utilizing EMR data are limited. OBJECTIVE: We aimed to develop and validate machine learning (ML) models by using diverse fields of EMR to predict the risk of 30-day adverse cardiac events after percutaneous intervention or bypass surgery. METHODS: EMR data of 5,184,565 records of 16,793 patients at a quaternary hospital between 2006 and 2016 were categorized into static basic (eg, demographics), dynamic time-series (eg, laboratory values), and cardiac-specific data (eg, coronary angiography). The data were randomly split into training, tuning, and testing sets in a ratio of 3:1:1. Each model was evaluated with 5-fold cross-validation and with an external EMR-based cohort at a tertiary hospital. Logistic regression (LR), random forest (RF), gradient boosting machine (GBM), and feedforward neural network (FNN) algorithms were applied. The primary outcome was 30-day mortality following invasive treatment. RESULTS: GBM showed the best performance with area under the receiver operating characteristic curve (AUROC) of 0.99; RF had a similar AUROC of 0.98. AUROCs of FNN and LR were 0.96 and 0.93, respectively. GBM had the highest area under the precision-recall curve (AUPRC) of 0.80, and the AUPRCs of RF, LR, and FNN were 0.73, 0.68, and 0.63, respectively. All models showed low Brier scores of <0.1 as well as highly fitted calibration plots, indicating a good fit of the ML-based models. On external validation, the GBM model demonstrated maximal performance with an AUROC of 0.90, while FNN had an AUROC of 0.85. The AUROCs of LR and RF were slightly lower at 0.80 and 0.79, respectively. The AUPRCs of GBM, LR, and FNN were similar at 0.47, 0.43, and 0.41, respectively, while that of RF was lower at 0.33. Among the categories in the GBM model, time-series dynamic data demonstrated a high AUROC of >0.95, contributing majorly to the excellent results. CONCLUSIONS: Exploiting the diverse fields of the EMR data set, the ML-based 30-day adverse cardiac event prediction models demonstrated outstanding results, and the applied framework could be generalized for various health care prediction models.
RESUMO
BACKGROUND: Although randomized trials have established that coronary artery bypass grafting (CABG) is, on average, the most effective revascularization strategy compared with percutaneous coronary intervention (PCI) in patients with diabetes and multivessel disease (MVD), individual patients differ in many characteristics that can affect the benefits and harms of treatment. The FREEDOM (Future Revascularization Evaluation in Patients with Diabetes Mellitus) score was developed to predict different outcomes with CABG vs PCI on the basis of 8 patient characteristics and the smoking-treatment interaction. OBJECTIVES: This study aimed to assess the ability of the 5-year major adverse cardiovascular event (MACE) model to predict treatment benefit of CABG vs PCI in the SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) and BEST (Bypass Surgery and Everolimus-Eluting Stent Implantation in the Treatment of Patients with Multivessel Coronary Artery Disease) trials. METHODS: This study identified 702 patients with diabetes and MVD to mirror the FREEDOM participants. Discrimination was assessed by C-index, and calibration was assessed by calibration plots in the PCI and CABG arms, respectively. The ability of the FREEDOM score to predict treatment benefit of CABG vs PCI was assessed. RESULTS: Overall, CABG was associated with a lower rate of 5-year MACE compared with PCI (12.4% vs 20.3%; log-rank P = 0.021) irrespective of a history of smoking (Pinteraction = 0.975). Both discrimination and calibration were helpful in the PCI arm (C-index: 0.69; slope: 0.96, intercept: -0.24), but moderate in the CABG arm (C-index: 0.61; slope: 0.61; intercept: -0.53). The FREEDOM score showed some heterogeneity of treatment benefit. CONCLUSIONS: The FREEDOM score could identify some heterogeneity of treatment benefit of CABG vs PCI for 5-year MACE. Until further prospective validations are performed, these results should be taken into consideration when using the FREEDOM score in patients with diabetes and MVD.

Background There are still limited data about the differential effect of sex on long-term outcomes after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for left main coronary artery disease. This extended follow-up study of the MAIN-COMPARE (Ten-Year Outcomes of Stents Versus Coronary-Artery Bypass Grafting for Left Main Coronary Artery Disease) registry evaluated clinical outcomes beyond 10 years. Methods and Results Of 2240 patients with unprotected left main coronary artery disease (PCI=1102 and CABG=1138), all-cause mortality, the composite of death, Q-wave myocardial infarction, or stroke, and target vessel revascularization were separately evaluated in both sexes. Of 2240 patients, 631 (28.2%) were women and 1609 (71.8%) were men. Women had lower 10-year incidences of death and serious composite outcomes than men. The adjusted 10-year risks of adverse outcomes were similar in men. However, the adjusted 10-year risks were different according to a prespecified period in women. In the short-term (0-1 year) period, PCI had a significantly lower risk for serious composite outcomes (adjusted hazard ratio [HR], 0.41; 95% CI, 0.19-0.91; P=0.03) compared with CABG. The adjusted risks for death and serious composite outcomes were significantly higher after PCI than after CABG, during the midterm (1-5 years) period (death; adjusted HR, 3.99; 95% CI, 2.01-7.92; P<0.001 and composite outcome; adjusted HR, 2.93; 95% CI, 1.59-5.39; P=0.001). Beyond 5 years, adjusted risks were similar after PCI and CABG in women. Conclusions In this 10-year extended follow-up study of patients undergoing left main coronary artery revascularization, we observed a time-dependent impact of sex on the long-term outcomes after PCI and CABG, especially in women, with significant interactions. However, these results warrant confirmation on larger series of studies. Registration URl: https://www.clinicaltrials.gov; Unique identifier: NCT02791412.

More evidence is required with respect to the comparative effectiveness of percutaneous coronary intervention (PCI) with second-generation drug-eluting stents (DESs) versus coronary artery bypass grafting (CABG) in contemporary clinical practice. This prospective observational registry-based study compared the outcomes of 6,647 patients with multivessel disease who underwent PCI with second-generation DES (n = 3,858) or CABG (n = 2,789) between January 2006 and June 2018 and for whom follow-up data were available for at least 2 to 13 years (median 4.8). The primary outcome was a composite of death, spontaneous myocardial infarction, or stroke. Baseline differences were adjusted using propensity scores and inverse probability weighting. In the overall cohort, there were no significant between-group differences in the adjusted risks for the primary composite outcome (hazard ratio [HR] for PCI vs CABG 1.03, 95% confidence interval [CI] 0.86 to 1.25, p = 0.73) and all-cause mortality (HR 0.95, 95% CI 0.76 to 1.20, p = 0.68). This relative treatment effect on the primary outcome was similar in patients with diabetes (HR 1.15, 95% CI 0.91 to 1.46, p = 0.25) and without diabetes (HR 0.95, 95% CI 0.73 to 1.22, p = 0.67) (p for interaction = 0.24). The adjusted risk of the primary outcome was significantly greater after PCI than after CABG in patients with left main involvement (HR 1.39, 95% CI 1.01 to 1.90, p = 0.044), but not in those without left main involvement (HR 0.94, 95% CI 0.76 to 1.16, p = 0.56) (p = 0.03 for interaction). In this prospective real-world long-term registry, we observed that the risk for the primary composite of death, spontaneous myocardial infarction, or stroke was similar between PCI with contemporary DES and CABG.

Background The long-term prognostic effect of the SYNTAX (Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) score (SS) after percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) for left main coronary artery disease is controversial. Methods and Results In the PRECOMBAT (Premier of Randomized Comparison of Bypass Surgery Versus Angioplasty Using Sirolimus-Eluting Stent in Patients With Left Main Coronary Artery Disease) trial, 600 patients with left main coronary artery disease were randomized to undergo PCI with drug-eluting stents (n=300) or CABG (n=300). We compared 10-year outcomes after PCI and CABG according to SS categories and evaluated the predictive value of SS in each revascularization arm. The primary outcome was a major adverse cardiac or cerebrovascular event (composite of death, myocardial infarction, stroke, or ischemia-driven target-vessel revascularization) at 10 years. Among 566 patients with valid SS measurement at baseline, 240 (42.4%) had low SS, 200 (35.3%) had intermediate SS, and 126 (22.3%) had high SS. The 10-year rates of major adverse cardiac or cerebrovascular events were not significantly different between PCI and CABG in low (21.6% versus 22.2%, P=0.97), intermediate (31.8% versus 22.2%; P=0.13), and high SS (46.2% versus 35.7%; P=0.31) (P-for-interaction=0.46). There were no significant interactions between SS categories and revascularization modalities for death (P=0.92); composite of death, myocardial infarction, or stroke (P=0.87); and target-vessel revascularization (P=0.06). Higher SS categories were associated with higher risks for major adverse cardiac or cerebrovascular events in the PCI arm but not in the CABG arm. Conclusions Ten-year clinical outcomes between PCI and CABG were not significantly different according to the SS. The SS was predictive of major adverse cardiac or cerebrovascular events after PCI but not after CABG. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT03871127.

Background Several trials reported differential outcomes after percutaneous coronary intervention with drug-eluting stents (DES) and coronary-artery bypass grafting (CABG) for multivessel coronary disease according to the presence of diabetes mellitus (DM). However, it is not well recognized how DM status affects very-long-term (10-year) outcomes after DES and CABG for left main coronary artery disease. Methods and Results In the PRECOMBAT (Premier of Randomized Comparison of Bypass Surgery versus Angioplasty using Sirolimus-Eluting Stent in Patients with Left Main Coronary Artery Disease) trial, patients with LMCA were randomly assigned to undergo PCI with sirolimus-eluting stents (n=300) or CABG (n=300). The primary outcome was the incidence of major adverse cardiac or cerebrovascular events (MACCE; a composite of death from any cause, myocardial infarction, stroke, or ischemia-driven target-vessel revascularization). Outcomes were examined in patients with (n=192) and without (n=408) medically treated diabetes. The follow-up was extended to at least 10 years for all patients (median, 11.3 years). The 10-year rates of MACCE were not significantly different between DES and CABG in patients with DM (36.3% versus 26.7%, respectively; hazard ratio [HR], 1.35; 95% CI, 0.83-2.19; P=0.23) and without DM (25.3% versus 22.9%, respectively; HR, 1.15; 95% CI, 0.79-1.67; P=0.48) (P-for-interaction=0.48). There were no significant between-group differences in composite of death, MI, or stroke, and all-cause mortality, regardless of DM status. TVR rates were consistently higher after DES than CABG. Conclusions In this 10-year extended follow-up of PRECOMBAT, we found no significant difference between DES and CABG with respect to the incidences of MACCE, serious composite outcome, and all-cause mortality in patients with and without DM with LMCA disease. However, owing to the limited number of patients and no adjustment for multiple testing, overall findings should be considered hypothesis-generating, highlighting the need for further research.

Gender differences have been recognized in several aspects of coronary artery disease (CAD). However, evidence for gender differences in long-term outcomes after left main coronary artery (LMCA) revascularization is limited. We sought to evaluate the impact of gender on outcomes after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for unprotected LMCA disease. We evaluated 4,320 patients with LMCA disease who underwent CABG (n = 1,456) or PCI (n = 2,864) from the Interventional Research Incorporation Society-Left MAIN Revascularization registry. The primary outcome was a composite of death, myocardial infarction (MI), or stroke. Among 4,320 patients, 968 (22.4%) were females and 3,352 (77.6%) were males. Compared to males, females were older, had a higher prevalence of hypertension and insulin-requiring diabetes, more frequently presented with acute coronary syndrome, but had less extensive CAD and less frequent left main bifurcation involvement. The adjusted risk for the primary outcome was not different after PCI or CABG in females and males (hazard ratio [HR] 1.09; 95% confidence interval [CI]: 0.73-1.63 and HR 0.97; 95% CI: 0.80-1.19, respectively); there was no significant interaction between gender and the revascularization strategy (P for interaction = 0.775). In multivariable analysis, gender did not appear to be an independent predictor for the primary outcome. In revascularization for LMCA disease, females and males had a comparable primary composite outcome of death, MI, or stroke with either CABG or PCI without a significant interaction of gender with the revascularization strategy.
