Effects of Liraglutide on Myocardial Function After Cardiac Surgery: A Secondary Analysis of the Randomised Controlled GLOBE Trial.

ABSTRACT: Previous studies demonstrated the cardioprotective properties of glucagon-like peptide-1 receptor agonists in patients with diabetes or cardiac disease. We investigated whether preoperative subcutaneous liraglutide improves myocardial function after cardiac surgery. We performed a pre-planned secondary analysis of adult patients undergoing cardiac surgery included in the GLOBE trial. Patients were randomised to receive 0.6 mg subcutaneous liraglutide on the evening before surgery and 1.2 mg after induction of anaesthesia, or matching placebo. Perioperative echocardiographic assessments, haemodynamic parameters, doses of vasoactive inotropic support and postoperative measurements of troponin, Creatine Kinase-MB , creatinine and lactate were compared between groups. The study population consisted of the entire intention-to-treat cohort of the GLOBE trial. In this study, 129 patients received liraglutide and 132 patients placebo. Baseline characteristics were comparable between groups. Postoperatively, 170 (65%) patients underwent echocardiography. In the liraglutide group, more patients had a normal left ventricular systolic function (68%, 59 patients) compared to placebo (53%, 44 patients), difference = 15%, 95%CI = 0-30, p = 0.049. Assessment of the right ventricle revealed no difference in function. Patients receiving short-term preoperative liraglutide treatment better maintained normal myocardial function after cardiac surgery. This study warrants further evaluation of the potential beneficial effects of GLP-1 receptor agonists in cardiac surgery patients.

Project description:BackgroundCardiopulmonary bypass (CPB) triggers marked cytokine release often followed by a systemic inflammatory response syndrome, associated with adverse postoperative outcomes. This trial investigates the intraoperative use of haemoadsorption (HA) during cardiac surgery with CPB to assess its impact on postoperative systemic inflammatory response.MethodsIn this prospective randomised controlled trial (ethics approval no. 5094-14DRKS00007928), patients (> 65 years) undergoing elective on-pump cardiac surgery were randomised to intraoperative HA (CytoSorb) during CPB or standard care without HA. Primary outcome was the difference in mean interleukin (IL)-6 serum concentrations between groups on intensive care unit (ICU) admission. The secondary outcomes included various clinical and biochemical endpoints. Statistical methods included paired and unpaired t-tests, Wilcoxon, Mann-Whitney U-tests, and chi-square tests.ResultsThirty-eight patients were allocated to receive either intraoperative HA (n = 19) or standard care (n = 19). The primary outcome, IL-6 levels on ICU admission, did not differ between the study group and controls (214.4 ± 328.8 vs. 155.8 ± 159.6 pg/ml, p = 0.511). During surgery pre- versus post-adsorber IL-2, IL-6, IL-8, IL-10, heparan sulfate and myoglobin post- levels were reduced. Furthermore, IL-6 levels did not differ between the study groups on day 1 and 2 in the ICU. While sequential organ failure assessment scores, lactate levels, and C-reactive protein and procalcitonin (PCT) showed no statistically significant differences. Regarding haemodynamic stability in the treatment group the cardiac index (3.2 ± 0.7 vs. 2.47 ± 0.47 l/min/m2, p = 0.012) on ICU day 2 increased, and lower fluid requirements as well as decreased fibrinogen requirement were observed. Need for renal replacement therapy did not differ though a shorter duration was observed in the treatment group. Time on ventilator, respiratory parameters, infectious complications, delirium scores, ICU and hospital lengths of stay, and mortality did not differ between groups.ConclusionHA did not reduce the IL-6 level on ICU admission or afterwards. Even though HA reduced cytokine load during cardiac surgery in the treatment group. There were no significant differences between groups in the postoperative course of other cytokine concentrations, organ dysfunction, ICU and hospital lengths of stay and mortality rates.

Project description:ObjectiveThe aim was to test the hypothesis that preoperative infusion of levosimendan would decrease patients' cardiac biomarker profiles during the immediate postoperative stage (troponin I and B-type natriuretic peptide levels) more efficiently than placebo after cardiopulmonary bypass.MethodsIn a randomised, placebo-controlled, double-blinded study, 30 paediatric patients were scheduled for congenital heart disease surgery. 15 patients (50%) received prophylactic levosimendan and 15 patients (50%) received placebo from 12 h before cardiopulmonary bypass to 24 h after surgery.ResultsTroponin I levels were higher in the placebo group at 0, 12, and 24 h after cardiopulmonary bypass, although the mean differences between the study groups and the 95% confidence intervals (CIs) for troponin I levels did not present statistically significant differences at any of the three time points considered (mean differences [95% CIs] - 3.32 pg/ml [- 19.34 to 12.70], - 2.42 pg/ml [- 19.78 to 13.95], and - 79.94 pg/ml [- 266.99 to 16.39] at 0, 12, and 24 h, respectively). A similar lack of statistically significant difference was observed for B-type natriuretic peptide (mean differences [95% CIs] 36.86 pg/dl [- 134.16 to 225.64], - 350.79 pg/dl [- 1459.67 to 557.45], and - 310.35 pg/dl [- 1505.76 to 509.82]). Lactic acid levels were significantly lower with levosimendan; the mean differences between the study groups and the 95% CIs for lactate levels present statistically significant differences at 0 h (- 1.52 mmol/l [- 3.19 to - 0.25]) and 12 h (- 1.20 mmol/l [- 2.53 to - 0.10]) after cardiopulmonary bypass. Oxygen delivery (DO2) was significantly higher at 12 h and 24 h after surgery (mean difference [95% CI] 627.70 ml/min/m2 [122.34-1162.67] and 832.35 ml/min/m2 [58.15 to 1651.38], respectively).ConclusionsLevosimendan does not significantly improve patients' postoperative troponin I and B-type natriuretic peptide profiles during the immediate postoperative stage in comparison with placebo, although both were numerically higher with placebo. Levosimendan, however, significantly reduced lactic acid levels and improved patients' DO2 profiles. These results highlight the importance of this new drug and its possible benefit with regard to myocardial injury; however, evaluation in larger, adequately powered trials is needed to determine the efficacy of levosimendan.

Project description:IntroductionOlder patients undergoing cardiac surgery carry the highest risk for developing major postoperative neurocognitive disorder (postoperative NCD or P-NCD) with up to 25% incidence 3 months after surgery. P-NCD is associated with significant morbidity, mortality, loss of independence, premature retirement and increased healthcare costs. This multicentre randomised trial is investigating the efficacy of postoperative dexmedetomidine sedation in reducing the incidence of major P-NCD after cardiac surgery compared with standard protocols. CODEX will be the largest interventional trial with major P-NCD as the primary outcome.Methods and analysisCODEX is recruiting patients ≥60 years old, undergoing elective cardiac surgery and without pre-existing major cognitive dysfunction or dementia. Eligible participants are randomised to receive postoperative dexmedetomidine or standard institutional sedation protocols in the intensive care unit. Baseline preoperative cognitive function is assessed with the computer-based Cogstate Brief Battery. The primary outcome, major P-NCD, 3 months after surgery is defined as a decrease in cognitive function ≥1.96 SD below age-matched, non-operative controls. Secondary outcomes include delirium, major P-NCD at 6/12 months, depressive symptoms, mild P-NCD and quality of surgical recovery at 3/6/12 months. The specific diagnostic criteria used in this protocol are consistent with the recommendations for clinical assessment and management of NCD from the Nomenclature Consensus Working Group on perioperative cognitive changes. Intention-to-treat analysis will compare major P-NCD at 3 months between study groups.Ethics and disseminationCODEX was approved by Sunnybrook Health Sciences Centre Research Ethics Board (REB) (Project ID 1743). This will be the first multicentre, randomised controlled trial to assess the efficacy of a pharmacological intervention to reduce the incidence of major P-NCD after cardiac surgery in patients ≥60 years old. Dissemination of the study results will include briefings of key findings and interpretation, conference presentations and peer-reviewed publications.Trial registration numberNCT04289142.

Project description:BackgroundLiraglutide is an antidiabetic agent with cardioprotective effect. The purpose of this study is to test efficacy of liraglutide to improve diabetic cardiomyopathy in patients with diabetes mellitus type 2 (DM2) without cardiovascular disease.MethodsPatients with DM2 were randomly assigned to receive liraglutide 1.8 mg/day or placebo in this double-blind trial of 26 weeks. Primary outcome measures were LV diastolic function (early (E) and late (A) transmitral peak flow rate, E/A ratio, early deceleration peak (Edec), early peak mitral annular septal tissue velocity (Ea) and estimated LV filling pressure (E/Ea), and systolic function (stroke volume, ejection fraction, cardiac output, cardiac index and peak ejection rate) assessed with CMR. Intention-to-treat analysis of between-group differences was performed using ANCOVA. Mean estimated treatment differences (95% confidence intervals) are reported.Results23 patients were randomized to liraglutide and 26 to placebo. As compared with placebo, liraglutide significantly reduced E (- 56 mL/s (- 91 to - 21)), E/A ratio (- 0.17 (- 0.27 to - 0.06)), Edec (- 0.9 mL/s2 * 10-3 (- 1.3 to - 0.2)) and E/Ea (- 1.8 (- 3.0 to - 0.6)), without affecting A (3 mL/s (- 35 to 41)) and Ea (0.4 cm/s (- 0.9 to 1.4)). Liraglutide reduced stroke volume (- 9 mL (- 16 to - 2)) and ejection fraction (- 3% (- 6 to - 0.1)), but did not change cardiac output (- 0.4 L/min (- 0.9 to 0.2)), cardiac index (- 0.1 L/min/m2 (- 0.4 to 0.1)) and peak ejection rate (- 46 mL/s (- 95 to 3)).ConclusionsLiraglutide reduced early LV diastolic filling and LV filling pressure, thereby unloading the left ventricle. LV systolic function reduced and remained within normal range. Future studies are needed to investigate if liraglutide-induced left ventricular unloading slows progression of diabetic cardiomyopathy into symptomatic stages.

Project description:IntroductionSteroids In caRdiac Surgery trial (SIRS) is a large international randomised controlled trial of methylprednisolone or placebo in patients undergoing cardiac surgery with the use of a cardiopulmonary bypass pump. At the time of surgery, compared with placebo, methylprednisolone divided into two intravenous doses of 250 mg each may reduce the risk of postoperative acute kidney injury (AKI).Methods and analysisWith respect to the study schedule, over 7000 substudy eligible patients from 81 centres in 18 countries were randomised in December 2013. The authors will use a logistic regression to estimate the adjusted OR of methylprednisolone versus placebo on the primary outcome of AKI in the 14 days following surgery (a postoperative increase in serum creatinine of ≥50%, or ≥26.5 μmol/L, from the preoperative value). The stage of AKI will also be considered, as will the outcome of AKI in those with and without preoperative chronic kidney disease. After receipt of grant funding, the authors began to record additional perioperative serum creatinine measurements in consecutive patients enrolled at substudy participating centres, and patients were invited to enroll in a 6-month serum creatinine collection. In these trial subpopulations, the authors will consider the outcome of AKI defined in alternate ways, and the outcome of a 6-month change in kidney function from the preoperative value.Ethics and disseminationThe authors were competitively awarded a grant from the Canadian Institutes of Health Research for this SIRS AKI substudy. Ethics approval was obtained for additional serum creatinine recordings in consecutive patients enrolled at participating centres. The additional kidney data collection first began for patients enrolled after 1 March 2012. In patients who provided consent, the last 6-month kidney outcome data will be collected in 2014. The results will be reported no later than 2015.Clinical trial registrationNumber NCT00427388.

Project description:BackgroundThe prevalence of type 2 diabetes (T2DM) in younger adults is growing. Compared to the late onset T2DM, it is well recognized that the disease tends to behave more aggressively in the younger age group with evidence of premature micro and macrovasular diseases and shorter life span. This increased mortality is largely attributed to cardiovascular complications. In a recent pilot study, young adults with T2DM were found to have significantly lower peak diastolic strain rate (PEDSR) on cardiac MRI (CMR), a forerunner of diabetic cardiomyopathy. Liraglutide, a glucagon like peptide-1 (GLP-1) analogue, is one of the new classes of glucose lowering therapies licensed to be used in management of T2DM. In randomised controlled trials, liraglutide improves glycaemic control by 1-1.5 % with an added benefit of weight loss of 2-3 kg. In addition, there is emerging evidence elucidating the cardioprotective effects of GLP-1 analogues independent of glycaemic control. In a small study, liraglutide has also been shown to improve cardiac function in patients with coronary ischaemia or congestive heart failure.Methods and aimsThis is a prospective, randomised, open-label, blind end-point (PROBE) active-comparator trial. A total of 90 obese eligible participants with T2DM (18-50 years) will be randomised to either liraglutide 1.8 mg once daily or sitagliptin 100 mg once daily for 26 weeks. The primary aim is to assess whether liraglutide improves diastolic function compared to sitagliptin as measured by PEDSR using CMR.DiscussionAlthough newer classes of GLP-1 analogues are made available in recent years, there are very few published studies demonstrating the beneficial effect of GLP-1 analogues on cardiovascular endpoints. In a recently published LEADER study, liraglutide has shown superiority to placebo in a population of type 2 diabetes with high risk of cardiovascular disease. To the best of our knowledge, there are no published studies establishing the effect of liraglutide on cardiac function in younger patients with T2DM on a larger scale. The LYDIA study will comprehensively describe changes in various parameters of cardiac structure and function in patients treated with liraglutide aiming to provide new evidence on effect of liraglutide on diastolic function in young obese people with T2DM.

Project description:BackgroundIn the United Kingdom, it is estimated that 5,000 patients sustain eye injuries or ocular trauma requiring hospital admission annually, of which 250 patients will be permanently blinded. This study explores the cost-effectiveness of Adjunctive Steroid Combination in Ocular Trauma (ASCOT) given during surgery versus standard treatment in vitreoretinal surgery in patients with open globe trauma.MethodsThis economic evaluation was embedded alongside the ASCOT RCT (ClinicalTrials.gov Identifier: NCT02873026). We conducted a primary cost-effectiveness analysis from a National Health Service perspective using the proportion of patients who achieved a visual acuity of 10 or more letter improvement on the Early Treatment Diabetic Retinopathy Study (ETDRS) scale as the measure of effect, in developing incremental cost-effectiveness ratios (ICERs). Secondary cost-utility analysis using the EuroQol 5 Dimension 5 Level (EQ-5D-5L) to generate a cost per quality-adjusted life-year (QALY), and a cost-effectiveness analysis using vision-specific quality of life (QoL) was conducted. Sensitivity analyses were also applied to investigate parameter uncertainties.ResultsThe sample size of the ASCOT intervention arm and standard care arm of this study was 130 and 129, respectively. The intervention cost per patient was estimated at £132. The proportion of participants with an ETDRS of 10 or more letter improvement was 0.47 for the ASCOT group with a mean cost of £5,526 per patient, while the standard care group had an effect of 0.43 with a mean cost of £5,099 per patient. The ICER value of the primary outcome was £12,178 per 10 or more letter improvement on the ETDRS score. The secondary result in terms of cost per QALYs gained had a probability of 44% being cost-effective at a willingness-to-pay threshold of £30,000/QALY gained.ConclusionsThough there is no formally accepted cost-effectiveness willingness-to-pay threshold for 10-letter or more improvement, the ASCOT intervention for open globe trauma is a low-cost intervention. The ASCOT intervention is not cost-effective when compared to the standard care in this group and setting. The proportion of patients in the ASCOT intervention arm with 10 or more letter improvement produced some positive results but this is outweighed by the costs.

Project description:AimsMost cardiac surgery patients, with or without diabetes, develop perioperative hyperglycaemia, for which intravenous insulin is the only therapeutic option. This is labour-intensive and carries a risk of hypoglycaemia. We hypothesized that preoperative administration of the glucagon-like peptide-1 receptor agonist liraglutide reduces the number of patients requiring insulin for glycaemic control during cardiac surgery.Materials and methodsIn this randomized, blinded, placebo-controlled, parallel-group, balanced (1:1), multicentre randomized, superiority trial, adult patients undergoing cardiac surgery in four Dutch tertiary hospitals were randomized to receive 0.6 mg subcutaneous liraglutide on the evening before surgery and 1.2 mg after induction of anaesthesia or matching placebo. Blood glucose was measured hourly and controlled using an insulin-bolus algorithm. The primary outcome was insulin administration for blood glucose >8.0 mmol/L in the operating theatre. Research pharmacists used centralized, stratified, variable-block, randomization software. Patients, care providers and study personnel were blinded to treatment allocation.ResultsBetween June 2017 and August 2018, 278 patients were randomized to liraglutide (139) or placebo (139). All patients receiving at least one study drug injection were included in the intention-to-treat analyses (129 in the liraglutide group, 132 in the placebo group). In the liraglutide group, 55 (43%) patients required additional insulin compared with 80 (61%) in the placebo group and absolute difference 18% (95% confidence interval 5.9-30.0, P = 0.003). Dose and number of insulin injections and mean blood glucose were all significantly lower in the liraglutide group. We observed no difference in the incidence of hypoglycaemia, nausea and vomiting, mortality or postoperative complications.ConclusionsPreoperative liraglutide, compared with placebo, reduces insulin requirements while improving perioperative glycaemic control during cardiac surgery.
