- OBJECTIVES: Patients with chronic obstructive pulmonary disease (COPD) who also have acute coronary syndromes are a high-risk population with a high mortality rate. Little is known about these patients following coronary artery bypass grafting (CABG). METHODS: Patients presenting with acute coronary syndromes between 2006 and 2014 with an angiogram showing 3-vessel disease or left main coronary artery involvement who were treated with CABG or percutaneous coronary intervention (PCI) only were included from the nationwide SWEDEHEART registry. Patients were stratified according to COPD status and compared with regard to outcome. The primary end-point was the 5-year mortality rate; secondary outcomes were the 30-day mortality rate and in-hospital complications after CABG. RESULTS: We identified 6985 patients in the population who had CABG (COPD prevalence = 8.0%) and 14 209 who had PCI only (COPD = 8.2%). Patients with COPD were older and had more comorbidities than patients without COPD. The 5-year mortality rate was nearly doubled in patients with COPD versus patients without COPD (CABG: 27.2% vs 14.5%, P < 0.001; PCI only: 50.1% vs 29.1%, P < 0.001). After adjusting for age, sex and comorbidities, patients with COPD in both CABG-treated [hazard ratio = 1.52 (1.25-1.86), P < 0.001] and PCI-treated populations still had a significantly higher 5-year mortality rate. COPD was also independently associated with significantly more postoperative infections in need of antibiotics [odds ratio = 1.48 (1.07-2.04), P = 0.017] and pneumonia [odds ratio = 2.21 (1.39-3.52), P = 0.001]. CONCLUSIONS: Patients with COPD presenting with acute coronary syndromes and severe coronary artery disease are a high-risk population following CABG or PCI only, with higher risk of long-term and short-term death and postoperative infections. Preventive measures, including careful monitoring for signs of infection and prompt antibiotic treatment when indicated, should be considered.

Forskningsöversikt (refereegranskat)abstract
- Enhanced recovery after surgery is well established in specialties such as colorectal surgery. It is achieved through the introduction of multiple evidence-based perioperative measures that aim to diminish postoperative organ dysfunction while facilitating recovery. This review aims to present consensus recommendations for the optimal perioperative management of patients undergoing thoracic surgery (principally lung resection). A systematic review of meta-analyses, randomized controlled trials, large non-randomized studies and reviews was conducted for each protocol element. Smaller prospective and retrospective cohort studies were considered only when higher-level evidence was unavailable. The quality of the evidence base was graded by the authors and used to form consensus recommendations for each topic. Development of these recommendations was endorsed by the Enhanced Recovery after Surgery Society and the European Society for Thoracic Surgery. Recommendations were developed for a total of 45 enhanced recovery items covering topics related to preadmission, admission, intraoperative care and postoperative care. Most are based on good-quality studies. In some instances, good-quality data were not available, and subsequent recommendations are generic or based on data extrapolated from other specialties. In other cases, no recommendation can currently be made because either equipoise exists or there is a lack of available evidence. Recommendations are based not only on the quality of the evidence but also on the balance between desirable and undesirable effects. Key recommendations include preoperative counselling, nutritional screening, smoking cessation, prehabilitation for high-risk patients, avoidance of fasting, carbohydrate loading, avoidance of preoperative sedatives, venous thromboembolism prophylaxis, prevention of hypothermia, short-acting anaesthetics to facilitate early emergence, regional anaesthesia, nausea and vomiting control, opioid-sparing analgesia, euvolemic fluid management, minimally invasive surgery, early chest drain removal, avoidance of urinary catheters and early mobilization after surgery. These guidelines outline recommendations for the perioperative management of patients undergoing lung surgery based on the best available evidence. As the recommendation grade for most of the elements is strong, the use of a systematic perioperative care pathway has the potential to improve outcomes after surgery.

- OBJECTIVES The aim was to investigate whether 2 weeks of inspiratory muscle training (IMT) could preserve respiratory muscle strength in high-risk patients referred for pulmonary resection on the suspicion of or confirmed lung cancer. Secondarily, we investigated the effect of the intervention on the incidence of postoperative pulmonary complications.METHODS The study was a single-centre, parallel-group, randomized trial with assessor blinding and intention-to-treat analysis. The intervention group (IG, n = 34) underwent 2 weeks of postoperative IMT twice daily with 2 × 30 breaths on a target intensity of 30% of maximal inspiratory pressure, in addition to standard postoperative physiotherapy. Standard physiotherapy in the control group (CG, n = 34) consisted of breathing exercises, coughing techniques and early mobilization. We measured respiratory muscle strength (maximal inspiratory/expiratory pressure, MIP/MEP), functional performance (6-min walk test), spirometry and peripheral oxygen saturation (SpO2), assessed the day before surgery and again 3–5 days and 2 weeks postoperatively. Postoperative pulmonary complications were evaluated 2 weeks after surgery.RESULTS The mean age was 70 ± 8 years and 57.5% were males. Thoracotomy was performed in 48.5% (n = 33) of cases. No effect of the intervention was found regarding MIP, MEP, lung volumes or functional performance at any time point. The overall incidence of pneumonia was 13% (n = 9), with no significant difference between groups [IG 6% (n = 2), CG 21% (n = 7), P = 0.14]. An improved SpO2 was found in the IG on the third and fourth postoperative days (Day 3: IG 93.8 ± 3.4 vs CG 91.9 ± 4.1%, P = 0.058; Day 4: IG 93.5 ± 3.5 vs CG 91 ± 3.9%, P = 0.02). We found no association between surgical procedure (thoracotomy versus thoracoscopy) and respiratory muscle strength, which was recovered in both groups 2 weeks after surgery.CONCLUSIONS Two weeks of additional postoperative IMT, compared with standard physiotherapy alone, did not preserve respiratory muscle strength but improved oxygenation in high-risk patients after lung cancer surgery. Respiratory muscle strength recovered in both groups 2 weeks after surgery.

- OBJECTIVES: Acute Type A aortic dissection remains a life-threatening disease, but there are indications that its surgical mortality is decreasing. The aim of this report was to study how surgical mortality has changed and what influences those changes.METHODS: Nordic Consortium for Acute Type A Aortic Dissection is a retrospective database comprising 1159 patients (mean age 61.6 ± 12.2 years, 68% male) treated for acute Type A aortic dissection at 8 centres in Denmark, Finland, Iceland and Sweden from 2005 to 2014. Data gathered included demographics, symptoms, type of procedure, complications and 30-day mortality.RESULTS: The annual number of operations increased significantly from 85 in 2005 to 150 in 2014 (P < 0.001). Chest pain was present in 85% of patients, 24% were hypotensive on presentation and 28% had malperfusion syndrome. Open distal anastomosis technique under hypothermic circulatory arrest was used in 85% of cases and its use increased significantly throughout the study. The 30-day mortality decreased from 24% in 2005 to 13% in 2014 (P = 0.003). Independent predictors for 30-day mortality were preoperative cardiac arrest, malperfusion syndrome, Penn Class C, Penn Class B and C and cardiopulmonary bypass time, whereas later calendar year and higher hospital operative volumes predicted improved survival.CONCLUSIONS: Surgical mortality for acute Type A aortic dissection remains high but has decreased significantly over the last decade. This correlated with later year of operation and increased the number of operations performed per year, indicating that cumulative surgical experience contributes significantly to improved surgical outcomes.

- OBJECTIVE: Dual antiplatelet therapy with ticagrelor and aspirin is associated with an increased risk of perioperative bleeding complications. Current guidelines recommend therefore discontinuation of ticagrelor 5 days before surgery to allow sufficient recovery of platelet function. It is not known how the time to recovery varies between individual patients after discontinuation of ticagrelor. METHODS: Twenty-five patients accepted for urgent coronary artery bypass surgery and treated with ticagrelor and aspirin were included in a prospective observational study. Platelet aggregation was evaluated with impedance aggregometry at five timepoints 12-96 h after discontinuation of ticagrelor. In a subset of patients (n = 15), we also tested the ex vivo efficacy of platelet concentrate supplementation on platelet aggregation. RESULTS: There was a gradual increase in mean adenosine diphosphate-induced platelet aggregation after discontinuation of ticagrelor. After 72 h, mean aggregation was 38 +/-23 aggregation units (U), which is above a previously suggested cut-off of 22 U, when patients can be operated without increased bleeding risk. However, there was a large interindividual variability (range 488 U at 72 h) and 6/24 patients (25%) had <22 U after 72 h. Ex vivo administration of platelet concentrate did not improve adenosine diphosphate-induced aggregation at any timepoint after ticagrelor discontinuation. CONCLUSIONS: Adenosine diphosphate-induced aggregation was acceptable after 72 h in the majority of patients but with a large interindividual variability. Due to the large variability, platelet function testing may prove to be a valuable tool in timing of surgery in patients with ongoing or recently stopped ticagrelor treatment. Adenosine diphosphate-induced aggregation was not improved by addition of platelet concentrate.

- Acute aortic dissection type A is a life-threatening condition, warranting immediate surgery. Presentation with sudden chest pain confers a risk of misdiagnosis as acute coronary syndrome resulting in subsequent potent antiplatelet treatment. We investigated the impact of dual antiplatelet therapy (DAPT) on bleeding and mortality using the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) database.The NORCAAD database is a retrospective multicentre database where 119 of 1141 patients (10.4%) had DAPT with ASA+clopidogrel (n=108) or ASA+ticagrelor (n=11) before surgery. The incidence of major bleeding and 30-day mortality was compared between DAPT and non-DAPT patients with logistic regression models before and after propensity score matching.Before matching, 51.3% of DAPT patients had major bleeding when compared to 37.7% of non-DAPT patients (P=0.0049). DAPT patients received more transfusions of red blood cells [median 8U (Q1-Q3 4-15) vs 5.5U (2-11), P<0.0001] and platelets [4U (2-8) vs 2U (1-4), P=0.0001]. Crude 30-day mortality was 19.3% vs 17.0% (P=0.60). After matching, major bleeding remained significantly more common in DAPT patients, 51.3% vs 39.3% [odds ratio (OR) 1.63, 95% confidence interval (CI) 1.05-2.51; P=0.028], but mortality did not significantly differ (OR 0.88, 95% CI 0.51-1.50; P=0.63). Major bleeding was associated with increased 30-day mortality (adjusted OR 2.44, 95% CI 1.72-3.46; P<0.0001).DAPT prior to acute aortic dissection repair was associated with increased bleeding and transfusions but not with mortality. Major bleeding per se was associated with a significantly increased mortality. Correct diagnosis is important to avoid DAPT and thereby reduce bleeding risk, but ongoing DAPT should not delay surgery.

- OBJECTIVES: Coronary artery bypass grafting using saphenous vein grafts (SVGs) in addition to the left internal mammary artery (IMA) graft is vitiated by poor long-term patency of the vein grafts. Hypothetically, the increased use of arterial grafts could confer even better outcomes. Our goal was to evaluate results after coronary artery bypass grafting in Sweden, where arterial grafts were used as a second conduit.METHODS: Within the Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) registry, we identified patients who had coronary artery bypass grafting from 2001 to 2015 using the IMA and the SVG, the radial artery (RA) or the additional IMA [bilateral IMA (BIMA)] as a second conduit. Deaths, postoperative incidence of coronary angiography and need for reintervention were recorded, and multivariable adjusted hazard ratios were calculated for different types of grafts.RESULTS: The study population comprised 45 319 cases of IMA + SVG, 1225 cases of IMA + RA and 1697 cases of BIMA. The mean follow-up time (SD) was 9.2 (4.2) years for IMA + SVG, 11.2 (4.0) years for IMA + RA grafts and 9.2 (5.2) years for the BIMA graft. The adjusted hazard ratio for death was (95% confidence interval) 1.06 (0.95-1.18) for IMA + RA and 1.21 (1.10-1.33) for BIMA grafts compared with IMA + SVG. The adjusted hazard ratio for the first angiographic examination was (95% confidence interval) 0.89 (0.78-1.01) for IMA + RA and 1.07 (0.96-1.20) for BIMA grafts. The adjusted hazard ratio for the need for reintervention was (95% confidence interval) 0.88 (0.74-1.04) for IMA + RA and 1.14 (0.98-1.32) for BIMA grafts.CONCLUSIONS: Patients who had arterial grafts as second conduits did not demonstrate a better outcome in any of the studied end-points. Radial artery grafts seem to be preferable to BIMA grafts as an alternative to an SVG.

- OBJECTIVES: Prolonged global cerebral ischaemia leads to irreversible injury, often with lethal outcome. Brain injuries are partly caused by the uncontrolled reperfusion that occurs once the circulation is re-established. Recent animal experiments suggest that controlled reperfusion following lengthy ischaemia might prevent severe brain injury. This study aimed at further exploring cerebral alterations and outcome following prolonged global cerebral ischaemia and mechanically manipulated reperfusion.METHODS: Three groups of pigs were included; one sham operated (n = 3) and two that underwent 30-min global cerebral ischaemia. All vessels that supply the brain were isolated intrathoracically, after which they were occluded for 30 min in the ischaemic groups. In one of the ischaemic groups uncontrolled reperfusion was applied (URep, n = 6), i.e. normal circulation was restored 30 min after arrested cerebral circulation. The second ischaemic group received mechanical reperfusion (MRep, n = 6) with leucocyte-filtered blood at constant flow and pressure for 20 min using extracorporeal circulation following the 30-min ischaemia, after which normal blood flow resumed. All animals were monitored for 3 h after start of uncontrolled reperfusion. Haemodynamic parameters, arterial and sagittal sinus blood gases, cerebral oxygen extraction rates and intraparenchymal biomarkers using microdialysis were measured. Brain histology was performed post-mortem.RESULTS: Global brain ischaemia led to the same extent of severe morphological changes at the level of light microscopy in the two ischaemic experimental groups, regardless of reperfusion protocol. Furthermore, no significant differences were found between the URep and MRep groups regarding cerebral blood gases or microdialysis biomarkers.CONCLUSIONS: Mechanical reperfusion following the current protocol does not modify brain alterations caused by 30 min of arrested cerebral circulation.

- OBJECTIVES: To report long-term survival and predictors of mortality in patients included in a large, contemporary, multicentre, multinational database: Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD), which consists of 8 centres in 4 Nordic countries.METHODS: Currently, NORCAAD includes 1159 patients operated between 2005 and 2014. In 30-day survivors (n = 955, 82%), the Kaplan-Meier and Cox proportional hazard methods were used to analyse medium-term (up to 8 years) survival and relative survival versus a matched normal population. Pre- and intraoperative predictors were expressed as hazard ratio (HR) with 95% confidence interval (95% CI).RESULTS: Cumulative follow-up was 3514 patient-years with a median of 3.2 years (range 0-10.2 years). Survival was 95% (95% CI 93-96) at 1 year, 86% (95% CI 83-88) at 5 years and 76% (95% CI 72-81) at 8 years. Relative survival versus a matched normal population was 95% (95% CI 94-97) at 1 year, 90% (95% CI 87-93) at 5 years and 85% (95% CI 80-90) at 8 years. In multivariable analysis, increased age (HR 1.05 per year, 95% CI 1.04-1.07), previous abdominal or thoracic aortic repair (HR 3.2, 95% CI 1.6-6.4) and chronic renal disease (HR 2.7, 95% CI 1.2-6.2) were associated with increased medium-term mortality. Open distal anastomosis (HR 0.55, 95% CI 0.35-0.87) and operation in the 2010-2014 period (HR 0.90, 95% CI 0.83-0.97) were associated with decreased medium-term mortality.CONCLUSIONS: Medium-term survival after acute Type A aortic dissection in the NORCAAD registry is satisfactory, close to a matched normal population and improved in the later part of the study period. The use of open distal anastomosis was associated with decreased medium-term mortality.

- Despite progress in management, mitral valve endocarditis (MVE) is still a life-threatening disease. We report our experience in surgical treatment of infective isolated MVE. A total of 140 operations in 128 patients for MVE performed between January 2000 and December 2015 were included in a retrospective study. There were 109 (78%) operations for native and 31 (22%) operations for prosthetic valve endocarditis. Preoperative and postoperative characteristics and mortality of patients were registered. Cox regression identified factors associated with mortality. Mean follow-up period was 68 months (range 1-168 months) and 100% complete. There were 13 deaths within 30 days after the 140 operations (9%). Severe perioperative complications occurred in 59 (42%) operations. Overall cumulative survival was 73% +/- 4 at 5 years and 62 +/- 5% at 10 years after the first operation. Age, diabetes, EuroSCORE II and perivalvular abscess were independent predictors for long-term mortality. Valve repair was performed in 76 (54%) operations and replacement in 64 (46%) operations. Thirty-day mortality for repair was 1%, and 5-year and 10-year cumulative survival was 86 +/- 4% and 77 +/- 6%, respectively. In the replacement group the 30-day mortality was 19% and cumulative survival at 5 years and 10 years was 55 +/- 7% and 41 +/- 8%, respectively. Postoperative complications occurred in 21% and 67%, respectively, after operations for repair and replacement. Ten (8%) patients had 12 reoperations for recurrent endocarditis. MVE requiring surgical treatment is a challenging disease with high hospital mortality after valve replacement. Mitral valve repair can be performed in suitable endocarditis patients with excellent results. Age, diabetes and EuroSCORE were independently associated with mortality in a multivariable model.

- Long-term mechanical circulatory support (LT-MCS) is an important treatment modality for patients with severe heart failure. Different devices are available, and many—sometimes contradictory—observations regarding patient selection, surgical techniques, perioperative management and follow-up have been published. With the growing expertise in this field, the European Association for Cardio-Thoracic Surgery (EACTS) recognized a need for a structured multidisciplinary consensus about the approach to patients with LT-MCS. However, the evidence published so far is insufficient to allow for generation of meaningful guidelines complying with EACTS requirements. Instead, the EACTS presents an expert opinion in the LT-MCS field. This expert opinion addresses patient evaluation and preoperative optimization as well as management of cardiac and non-cardiac comorbidities. Further, extensive operative implantation techniques are summarized and evaluated by leading experts, depending on both patient characteristics and device selection. The faculty recognized that postoperative management is multidisciplinary and includes aspects of intensive care unit stay, rehabilitation, ambulatory care, myocardial recovery and end-of-life care and mirrored this fact in this paper. Additionally, the opinions of experts on diagnosis and management of adverse events including bleeding, cerebrovascular accidents and device malfunction are presented. In this expert consensus, the evidence for the complete management from patient selection to end-of-life care is carefully reviewed with the aim of guiding clinicians in optimizing management of patients considered for or supported by an LT-MCS device.

- OBJECTIVES: Right ventricular (RV) failure is a major cause of morbidity and mortality after left ventricular assist device (LVAD) placement and remains hard to predict. We hypothesized that partial surgical exclusion of the RV with a modified Glenn shunt during LVAD treatment would reduce RV stroke work.METHODS: An LVAD was implanted in eight pigs and a modified Glenn shunt was constructed. A conductance pressure-volume catheter was placed in the right ventricle through the apex. Haemodynamic data and pressure-volume loops were obtained at the following time periods: (i) baseline, (ii) open shunt, (iii) LVAD with closed shunt and (iii) LVAD and open shunt.RESULTS: During LVAD therapy, the right atrial (RA) pressure increased from 9 mmHg (9-9) to 15 mmHg (12-15), P = 0.01. RV stroke volume increased from 30 ml (29-40) to 51 ml (42-53), P < 0.01. Also, RV stroke work increased to 708 mmHg ml (654-1193) from 535 mmHg ml (424-717), P = 0.04, compared with baseline. During LVAD therapy in combination with a Glenn shunt, the RA pressure decreased from 15 mmHg (12-15) to 10 mmHg (7-11) when compared with LVAD therapy only, P = 0.01. A decrease in RV stroke work from 708 mmHg ml (654-1193) to 465 mmHg ml (366-711), P = 0.04, was seen when the LVAD was combined with a shunt, not significantly different from the baseline value (535 mmHg ml). The developed pressure in the right ventricle decreased from 29 mmHg (26-32) to 21 mmHg (20-24), P < 0.01. The pressure-volume loops of the RV show a significant reduction of RV stroke work during the use of the shunt with LVAD treatment.CONCLUSIONS: A modified Glenn shunt reduced RV volumes, RV stroke work and RA pressure during LVAD therapy in an experimental model of heart failure in pigs.

- The implementation of new surgical techniques offers chances but carries risks. Usually, several years pass before a critical appraisal and a balanced opinion of a new treatment method are available and rely on the evidence from the literature and expert's opinion. The frozen elephant trunk (FET) technique has been increasingly used to treat complex pathologies of the aortic arch and the descending aorta, but there still is an ongoing discussion within the surgical community about the optimal indications. This paper represents a common effort of the Vascular Domain of EACTS together with several surgeons with particular expertise in aortic surgery, and summarizes the current knowledge and the state of the art about the FET technique. The majority of the information about the FET technique has been extracted from 97 focused publications already available in the PubMed database (cohort studies, case reports, reviews, small series, meta-analyses and best evidence topics) published in English.

- OBJECTIVES: We sought to analyse perioperative outcome, long-term mortality, frequency and causes of reintervention, and survival benefit in a contemporary cohort of patients undergoing proximal thoracic aortic surgery.METHODS: Participants comprised all patients undergoing open surgery for proximal thoracic aortic aneurysm (TAA) (n=319) and thoracic aortic dissection type A (TAD) (n=229) during 2005-2014 at the Department of Thoracic Surgery, Uppsala University Hospital. Long-term survival was compared to age- and sex-matched controls. Perioperative mortality and morbidity, event-free survival and causes of reoperation were also analysed.RESULTS: Long-term mortality was normalized in patients with TAA, and a survival benefit was seen as early as 20 months when corrected for time lost due to perioperative mortality. Long-term survivors undergoing surgery for TAD, on the other hand, had a 10-year mortality of 130% [95% confidence interval (95% CI) 120-140%] compared to age- and sex-matched controls. Moreover, their event-free survival was half that of patients with TAA (hazard ratio 2.3; 95% CI 1.7-3.2). Reintervention (i.e. reoperation or thoracic endovascular aortic repair) was also twice as common in the TAD patients (odds ratio 2.0; 95% CI 1.1-3.5). The dominant causes for reoperation among TAD patients were aortic insufficiency, aortic arch aneurysm and infection.CONCLUSIONS: Surgery for TAA is relatively safe, normalizes long-term mortality and confers an early survival benefit. However, TAD surgery carries a high risk of perioperative mortality and morbidity, as well as increased long-term mortality and risk of reintervention.

- Our goal was to compare short- and midterm outcomes after coronary artery bypass grafting (CABG) using 2 different revascularization strategies.A total of 6895 patients were included who had CABG in Sweden from 2009 to 2015 using the left internal mammary artery to the left anterior descending artery and either a single sequential saphenous vein graft connecting the left and right coronary territories to the aorta (snake graft, n=2122) or separate vein grafts to both territories (n=4773). Data were obtained from the Swedish Web System for Enhancement of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) and the Swedish Patient Registry. The groups were compared using adjusted logistic regression for short-term (30-day) and Cox regression and flexible parametric survival models for midterm outcomes. Primary outcome was a composite of all-cause mortality, myocardial infarction (MI), reangiography and new revascularization. The median follow-up time was 35months.At 30days, the incidences of the composite end point [odds ratio (OR) 1.31, 95% confidence interval (CI) 1.03-1.68; P=0.03] and reangiography (OR 1.51, 95% CI 1.07-2.14; P=0.02) were higher in the snake group. There was also a trend towards higher mortality (OR 1.47, 95% CI 0.97-2.22; P=0.07). The event rates during the complete follow-up period were 6.5 (5.9-7.2) and 5.7 (5.3-6.1) per 100 person-years for the snake group and the separate vein group, respectively. At the midterm follow-up, no significant difference between the groups could be shown for the composite end point [hazard ratio (HR) 1.08, 95% CI 0.95-1.22; P=0.24], mortality (HR 0.95, 95% CI 0.79-1.14; P=0.56), MI (HR 1.11, 95% CI 0.88-1.41; P=0.39) or new revascularization (HR 1.19, 95% CI 0.94-1.50; P=0.15), whereas reangiography remained more common in the snake group (HR 1.25, 95% CI 1.05-1.48; P=0.01).Snake grafts were associated with a higher rate of early postoperative complications, possibly reflecting a more demanding surgical technique, whereas midterm outcomes were comparable. Based on these data, one strategy cannot be recommended over the other.

- 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..
