- Objective: Neurocognitive impairment is common after cardiac surgery but few studies have examined the relationship between postoperative neuropsychological test performance and everyday behavior. The influence of postoperative cognitive impairment on car driving has previously not been investigated. The purpose of this study was to evaluate neurocognitive function and driving performance after coronary artery bypass grafting (CABG).Methods: Twenty-seven patients who underwent coronary artery bypass grafting with standard cardiopulmonary bypass technique and 20 patients scheduled for percutaneous coronary intervention (PCI) under local anesthesia (control group) were enrolled in this prospective study conducted from April 1999 to September 2000. Complete data were obtained in 23 and 19 patients, respectively. The patients underwent neuropsychological examination with a test battery including 12 tests, a standardized on-road driving test and a test in an advanced driving simulator before and 4–6 weeks after intervention.Results: More patients in the coronary artery bypass grafting group (n=11, 48%) than in the percutaneous coronary intervention group (n=2, 10%) showed a cognitive decline after intervention (P=0.01). In the on-road driving test, patients who underwent coronary artery bypass grafting deteriorated after surgery in the cognitive demanding parts like traffic behavior (P=0.01) and attention (P=0.04). Patients who underwent percutaneous intervention deteriorated in maneuvering of the vehicle (P=0.04). No deterioration was detected in the simulator in any of the groups after intervention. Patients with a cognitive decline after intervention also tended to drop in the on-road driving scores to a larger extent than did patients without a cognitive decline.Conclusion: This study indicates that cognitive functions important for safe driving may be influenced after cardiac surgery.

- OBJECTIVE: This article presents a study of postoperative atrial fibrillation (AF) and its long-term effects on mortality and heart rhythm.METHODS: The study cohort consisted of 571 patients with no history of AF who underwent primary aortocoronary bypass surgery from 1999 to 2000. Postoperative AF occurred in 165/571 patients (28.9%). After a median follow-up of 6 years, questionnaires were obtained from 91.6% of surviving patients and an electrocardiogram (ECG) from 88.6% of all patients. Data from hospitalisations due to arrhythmia or stroke during follow-up were analysed. The causes of death were obtained for deceased patients.RESULTS: In postoperative AF patients, 25.4% had atrial fibrillation at follow-up compared with 3.6% of patients with no AF at surgery (p<0.001). An episode of postoperative AF was the strongest independent risk factor for development of late AF, with an adjusted risk ratio of 8.31 (95% confidence interval (CI) 4.20-16.43). Mortality was 29.7% (49 deaths/165 patients) in the AF group and 14.8% (60 deaths/406 patients) in the non-AF group (p<0.001). Death due to cerebral ischaemia was more common in the postoperative AF group (4.2% vs 0.2%, p<0.001), as was death due to myocardial infarction (6.7% vs 3.0%, p=0.041). Postoperative AF was an age-independent risk factor for late mortality, with an adjusted hazard ratio of 1.57 (95% CI 1.05-2.34).CONCLUSIONS: Postoperative AF patients have an eightfold increased risk of developing AF in the future, and a doubled long-term cardiovascular mortality.

- The association between obesity and graft failure after coronary artery bypass grafting has not been previously investigated.We pooled individual patient data from randomized clinical trials with systematic post-operative coronary imaging to evaluate the association between obesity and graft failure at the individual graft and patient levels. Penalized cubic regression splines and mixed-effects multivariable logistic regression models were performed.Six trials comprising 3,928 patients and 12,048 grafts were included. The median time to imaging was 1.03 (IQR, 1.00-1.09) years. By body mass index (BMI) category, 800 (20.4%) patients were normal weight (BMI 18.5-24.9), 1,668 (42.5%) were overweight (BMI 25-29.9), 983 (25.0%) were obesity class 1 (BMI 30-34.9), 344 (8.8%) were obesity class 2 (BMI 35-39.9), and 116 (2.9%) were obesity class 3 (BMI 40+). As a continuous variable, BMI was associated with reduced graft failure (adjusted odds ratio [aOR] 0.98 [95% CI, 0.97-0.99]) at the individual graft level. Compared to normal weight patients, graft failure at the individual graft level was reduced in overweight (aOR 0.79 [95% CI, 0.64-0.96]), obesity class 1 (aOR 0.81 [95% CI, 0.64-1.01]), and obesity class 2 (aOR 0.61 [95% CI, 0.45-0.83]) patients, but not different compared to obesity class 3 (aOR 0.94 [95% CI, 0.62-1.42]) patients. Findings were similar, but did not reach significance, at the patient level.In a pooled individual patient data analysis of randomized clinical trials, BMI and obesity appear to be associated with reduced graft failure at one year after coronary artery bypass grafting.

- Individual patient data (IPD) meta-analyses build upon traditional (aggregate data) meta-analyses by collecting IPD from the individual studies rather than using aggregated summary data. Although both traditional and IPD meta-analyses produce a summary effect estimate, IPD meta-analyses allow for the analysis of data to be performed as a single dataset. This allows for standardization of exposure, outcomes, and analytic methods across individual studies. IPD meta-analyses also allow the utilization of statistical methods typically used in cohort studies, such as multivariable regression, survival analysis, propensity score matching, uniform subgroup and sensitivity analyses, better management of missing data, and incorporation of unpublished data. However, they are more time-intensive, costly, and subject to participation bias. A separate issue relates to the meta-analytic challenges when the proportional hazards assumption is violated. In these instances, alternative methods of reporting time-to-event estimates, such as restricted mean survival time should be used. This statistical primer summarizes key concepts in both scenarios and provides pertinent examples.

- 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: Severe pulmonary hypertension (PH) is a known risk factor in valvular surgery. In the present study, we hypothesized that the assessment of pressure reflection (PR) in the pulmonary circulation, indicating increased pulmonary vascular resistance, might improve the identification of patients with increased morbidity and mortality following surgery for severe mitral regurgitation. METHODS: A total of 103 patients without atrial fibrillation were divided into three groups: Group 1 (n = 48), patients without PR; Group 2 (n = 36), patients with PR and pulmonary artery systolic pressure (PASP) ≤60 mmHg and Group 3 (n = 19), patients with PR and PASP >60 mmHg. Three variables related to PR were selected: the acceleration time in the right ventricular outflow tract (RVOT), the interval between peak velocity in the RVOT and peak tricuspid regurgitant jet velocity and the right ventricular pressure increase after peak RVOT velocity. RESULTS: There were no differences between groups in age, ejection fraction, need for coronary bypass grafting or creatinine. Patients with PR (Groups 2 and 3) had more use of vasoactive drugs (overall P < 0.0001, Group 1 vs Group 2 P = 0.018). The proportion of patients with >24 h in the intensive care unit was 27% in Group 1, 54% in Group 2 and 84% in Group 3 (overall P < 0.0001, Group 1 vs Group 2 P = 0.006). The in-hospital mortality in patients without PR (n = 49) was 0% compared with 10.9% in patients with PR (P = 0.029). CONCLUSIONS: Echocardiography assessment of PR in the pulmonary circulation and severe PH may identify patients with adverse outcome following mitral surgery.

Acetylsalicylic acid treatment until surgery reduces oxidative stress and inflammation in patients undergoing coronary artery bypass grafting
- 2013
-
Ingår i: European Journal of Cardio-Thoracic Surgery. - : Oxford University Press (OUP). - 1010-7940 .- 1873-734X. ; 43:6, s. 1154-1163

- OBJECTIVES: Acetylsalicylic acid (ASA) is a cornerstone in the treatment of coronary artery disease (CAD) due to its antiplatelet effect. Cessation of aspirin before coronary artery bypass grafting (CABG) is often recommended to avoid bleeding, but the practice is controversial because it is suggested to worsen the underlying CAD. The aims of the present prospective, randomized study were to assess if ASA administration until the day before CABG decreases the oxidative load through a reduction of inflammation and myocardial damage, compared with patients with preoperative discontinuation of ASA. METHODS: Twenty patients scheduled for CABG were randomly assigned to either routine ASA-treatment (160 mg daily) until the time of surgery (ASA), or to ASA-withdrawal 7 days before surgery (No-ASA). Blood-samples were taken from a radial artery and coronary sinus, during and after surgery and analysed for 8-iso-prostaglandin (PG) F(2α); a major F(2)-isoprostane, high-sensitivity C-reactive protein (hs-CRP), cytokines and troponin T. Left ventricle Tru-Cut biopsies were taken from viable myocardium close to the left anterior descending artery just after connection to cardiopulmonary bypass, and before cardioplegia were established for gene analysis (Illumina HT-12) and immunohistochemistry (CD45). RESULTS: 8-Iso-PGF(2α) at baseline (t(1)) were 111 (277) pmol/l and 221 (490) pmol/l for ASA and No-ASA, respectively (P = 0.065). Area under the curve showed a significantly lower level in plasma concentration of 8-iso-PGF(2α) and hsCRP in the ASA group compared with the No-ASA group with (158 pM vs 297 pM, P = 0.035) and hsCRP (8.4 mg/l vs 10.1 mg/l, P = 0.013). All cytokines increased during surgery, but no significant differences between the two groups were observed. Nine genes (10 transcripts) were found with a false discovery rate (FDR) <0.1 between the ASA and No-ASA groups. CONCLUSIONS: Continued ASA treatment until the time of CABG reduced oxidative and inflammatory responses. Also, a likely beneficial effect upon myocardial injury was noticed. Although none of the genes known to be involved in oxidative stress or inflammation took a different expression in myocardial tissue, the genetic analysis showed interesting differences in the mRNA level. Further research in this field is necessary to understand the role of the genes.

- Pacemakers, implantable cardiac defibrillators, and cardiac resynchronization therapy devices are potentially life-saving treatments for a number of cardiac conditions, but are not without risk. Most concerning is the risk of a cardiac implantable electronic device (CIED) infection, which is associated with significant morbidity, increased hospitalizations, reduced survival, and increased healthcare costs. Recommended preventive strategies such as administration of intravenous antibiotics before implantation are well recognized. Uncertainties have remained about the role of various preventive, diagnostic, and treatment measures such as skin antiseptics, pocket antibiotic solutions, anti-bacterial envelopes, prolonged antibiotics post-implantation, and others. Guidance on whether to use novel device alternatives expected to be less prone to infections and novel oral anticoagulants is also limited, as are definitions on minimum quality requirements for centres and operators and volumes. Moreover, an international consensus document on management of CIED infections is lacking. The recognition of these issues, the dissemination of results from important randomized trials focusing on prevention of CIED infections, and observed divergences in managing device-related infections as found in an European Heart Rhythm Association worldwide survey, provided a strong incentive for a 2019 International State-of-the-art Consensus document on risk assessment, prevention, diagnosis, and treatment of CIED infections.

- Background: Improved quantitative understanding of in vivo leaflet geometry in ischemic mitral regurgitation (IMR) is needed to improve reparative techniques, yet few data are available due to current imaging limitations. Using marker technology we tested the hypotheses that IMR (1) occurs chiefly during early systole; (2) affects primarily the valve region contiguous with the myocardial ischemic insult; and (3) results in systolic leaflet edge restriction. Methods: Eleven sheep had radiopaque markers sutured as five opposing pairs along the anterior (A1–E1) and posterior (A2–E2) mitral leaflet free edges from the anterior commissure (A1–A2) to the posterior commissure (E1–E2). Immediately postoperatively, biplane videofluoroscopy was used to obtain 4D marker coordinates before and during acute proximal left circumflex artery occlusion. Regional mitral orifice area (MOA) was calculated in the anterior (Ant-MOA), middle (Mid-MOA), and posterior (Post-MOA) mitral orifice segments during early systole (EarlyS), mid systole (MidS), and end systole (EndS). MOA was normalized to zero (minimum orifice opening) at baseline EndS. Tenting height was the distance of the midpoint of paired markers to the mitral annular plane at EndS. Results: Acute ischemia increased echocardiographic MR grade (0.5 ± 0.3 vs 2.3 ± 0.7, p < 0.01) and MOA in all regions at EarlyS, MidS, and EndS: Ant-MOA (7 ± 10 vs 22 ± 19 mm2, 1 ± 2 vs18 ± 16 mm2, 0 vs 17 ± 15 mm2); Mid-MOA (9 ± 13 vs 25 ± 17 mm2, 3 ± 6 vs 21 ± 19 mm2, 0 vs 25 ± 17 mm2); and Post-MOA (8 ± 10 vs 25 ± 16, 2 ± 4 vs 22 ± 13 mm2, 0 vs 23 ± 13 mm2), all p < 0.05. There was no change in MOA throughout systole (EarlyS vs MidS vs EndS) during baseline conditions or ischemia. Tenting height increased with ischemia near the central and the anterior commissure leaflet edges (B1–B2: 7.1 ± 1.8 mm vs 7.9 ± 1.7 mm, C1–C2: 6.9 ± 1.3 mm vs 8.0 ± 1.5 mm, both p < 0.05). Conclusions: MOA during ischemia was larger throughout systole, indicating that acute IMR in this setting is a holosystolic phenomenon. Despite discrete postero-lateral myocardial ischemia, Post-MOA was not disproportionately larger. Acute ovine IMR was associated with leaflet restriction near the central and the anterior commissure leaflet edges. This entire constellation of annular, valvular, and subvalvular ischemic alterations should be considered in the approach to mitral repair for IMR.

- The purpose of this study was to describe mortality during the 2-year-period after coronary artery bypass surgery (CABG) in relation to perioperative risk factors and urgency of operation. All the patients in western Sweden were included in whom CABG was performed between June 1988 and June 1991, without concomitant procedures or re-operations. The study was prospective in design. In all, 2000 patients were operated upon and 186 (9.3%) of the operations were acute. There was a significant relationship between the urgency of the operation and mortality. Early mortality was 2.4% in elective operations and 5.4-62.5% in urgent to emergency operations. The 30-day to 2-year mortality was 4.2%. The perioperative risk indicators independently associated with early mortality were neurologic complications, serum-aspartate aminotransferase (S-ASAT) more than 2.0 microkat/l, urgency of operation, the use of circulatory assist devices, re-operation and ventilator time more than 24 h. The risk indicators for mortality after 30 days were pneumothorax, longer intensive care unit (ICU) time, the use of inotropic drugs and neurologic complications. In conclusion, the multivariate analysis reveals the urgency of the operation as a predictor of early mortality after CABG, but no significant association with mortality was found after 30 days. When excluding death within 30 days, three additional independent predictors of mortality were identified.

- Objective: To describe the impact of coronary artery bypass grafting on chest pain during 2 years of follow-up after the operation and to identify predictors of chest pain and its relationship to myocardial ischaemia 2 years after the operation. Methods: Patients were approached with a questionnaire at the time of coronary angiography (1291) and 3 months (1664), 1 year (1638) and 2 years (1613) after coronary artery bypass grafting. Two years after the operation, a computerised 12-lead electrocardiogram was obtained during a standardised bicycle exercise test (618). Results: Prior to surgery, 37% of the patients were unable to perform physical activity compared with 6% after the operation (PB0.0001 for change in degree of limitation). Only 3% had no chest pain at all prior to the operation, while 58% of the patients were free from chest pain 2 years after surgery (PB0.0001). We found no correlation between patients reporting chest pain and signs of ischaemia at exercise test, but there was a highly significant correlation with chest pain during the exercise test (PB0.0001). Independent predictors of chest pain were severity of preoperative angina (PB0.0001), younger age (P 0.0009), previous coronary artery bypass grafting (P 0.003), duration of symptoms (P 0.005), the need for prolonged cardiopulmonary bypass (P 0.04) and the absence of left main stenosis (P 0.04). Conclusion: Independent predictors of chest pain were identified 2 years after coronary artery bypass grafting. There was a dramatic improvement after coronary artery bypass grafting. However, almost half the patients complained of some kind of chest pain even after the operation. This chest pain correlated well with chest pain during the exercise test but not with signs of myocardial ischaemia.

- 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: Stroke is a serious complication in patients with acute type A aortic dissection (ATAAD). Previous studies investigating stroke in ATAAD patients have been limited by small cohorts and have shown diverging results. We sought to identify risk factors for stroke and to evaluate the effect of stroke on outcomes in surgical ATAAD patients. METHODS: The Nordic Consortium for Acute Type A Aortic Dissection database included patients operated for ATAAD at 8 Scandinavian Hospitals between 2005 and 2014. RESULTS: Stroke occurred in 177 (15.7%) out of 1128 patients. Patients with stroke presented more frequently with cerebral malperfusion (20.6% vs 6.3%, P < 0.001), syncope (30.6% vs 17.6%, P < 0.001), cardiogenic shock (33.1% vs 20.7%, P < 0.001) and pericardial tamponade (25.9% vs 14.7%, P < 0.001) and more often underwent total aortic arch replacement (10.7% vs 4.7%, P = 0.016), compared to patients without stroke. In the 86 patients presenting with cerebral malperfusion, 38.4% developed stroke. Thirty-day and 5-year mortality in patients with and without stroke were 27.1% vs 13.6% and 42.9% vs 25.6%, respectively. Stroke was an independent predictor of early- [odds ratio 2.02, 95% confidence interval (CI) 1.34-3.05; P < 0.001] and midterm mortality (hazard ratio 1.68, 95% CI 1.27-2.23; P < 0.001). CONCLUSIONS: Stroke in ATAAD patients is associated with increased early- and midterm mortality. Preoperative cerebral malperfusion and impaired haemodynamics, as well as total aortic arch replacement, were more frequent among patients who developed stroke. Importantly, a large proportion of patients presenting with cerebral malperfusion did not develop a permanent stroke, indicating that signs of cerebral malperfusion should not be considered a contraindication for surgery.
