Effect of Liraglutide on Cardiometabolic Risk Profile in People with Coronary Artery Disease with or without Type 2 Diabetes: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: Background: Whether liraglutide use improves cardiometabolic risk factors in different subsets of subjects with coronary artery disease (CAD) remains unclear. In a systematic review and meta-analysis, we quantified the effects of liraglutide on cardiometabolic risk profile in subjects with CAD with or without type 2 diabetes mellitus (T2D). Methods: Online database searches were conducted in PubMed, Scopus, EMBASE, Web of Science, Cochrane library, and Google Scholar from incept up to 15th January 2021. We identified randomized controlled trials (RCTs) assessing the effects of liraglutide compared to placebo on cardiometabolic risk profile. We used the random- or fixed-effect models to pool the weighted mean differences (WMDs) and 95% confidence intervals (CIs). Results: Out of a total of 7,320 citations, six articles (seven RCTs) with 294 subjects with CAD (mean age, 61.21 years; 19% women) were included. Our findings presented as WMD and 95% CI showed a statistical significant decrease in hemoglobin A1c (HbA1c) [-0.36%; -0.47; -0.26, p < 0.001; I ² = 0.0% (with 6 RCTs)], body mass index (BMI) [-0.61 kg/m²; -1.21; -0.01, p = 0.047; I ² = 72.2% (with five RCTs)], and waist circumference [-2.41 cm; -3.47; -1.36, p < 0.001; I ² = 0.0% (with three RCTs)]. Through a set of subgroup analyses, we found a significant reduction in BMI in CAD patients with T2D [WMD = -1.06; 95% CI, -1.42, -0.70, p < 0.001; I ² = 0.0% (with three RCTs)] compared to CAD only patients [WMD = -0.08; 95% CI, -0.45, 0.29, p = 0.66; I ² = 0.0% (with two RCTs)] in the liraglutide group compared with the placebo group. No significant changes in heart rate, blood pressure, and lipid profiles were observed. Conclusions: Among people with established CAD, liraglutide significantly improved HbA1c, BMI, and waist circumference values. The effect of liraglutide on BMI was more robust in individuals with T2D compared to those without.

Project description:Background Coronary artery bypass graft (CABG) surgery represents the preferred revascularization strategy for most patients with diabetes and multivessel disease. We aimed to evaluate the role of optimized, perioperative cardiometabolic targets on long-term survival in patients who underwent CABG. Methods and Results Single-institution retrospective study was conducted in patients with diabetes who underwent CABG between January 2010 and June 2018. Demographic, surgical, and cardiometabolic determinants were identified during the perioperative period. Clinical characteristics and longitudinal survival outcomes data were obtained. A total of 1534 patients with CABG were considered for analysis and 1273 met inclusion criteria. The mean age of patients was 63.3 years (95% CI, 62.7-63.8 years), and most were men (65%) and Hispanic or Latino (47%). Comorbidities included hypertension (95%) and dyslipidemia (88%). In total, 490 patients (52%) had a low-density lipoprotein cholesterol level >70 mg/dL. Furthermore, 390 patients (31%) had uncontrolled systolic blood pressure >130 mm Hg. Last, only 386 patients (29%) had a hemoglobin A1c level between 6% and 7%. At 5 years, 121 patients (10%) died. Failure to achieve goal systolic blood pressure was associated with all-cause (hazard ratio [HR], 1.573; 95% CI, 1.048-2.362 [P=0.029]) and cardiovascular (HR, 2.023; 95% CI, 1.196-3.422 [P=0.009]) mortality at 5 years post-CABG. In contrast, prescription of a statin during the perioperative interval demonstrated a protective effect for all-cause (HR, 0.484; 95% CI, 0.286-0.819 [P=0.007]) and cardiovascular (HR, 0.459; 95% CI, 0.229-0.920 [P=0.028]) mortality. There was no association between achievement of low-density lipoprotein cholesterol, triglycerides, non-high-density lipoprotein cholesterol, or hemoglobin A1c level goals and mortality risk at 5 years. Conclusions Among patients with diabetes, blood pressure control and statin therapy were the most important perioperative cardiometabolic survival determinants 5 years after CABG.

Project description:IntroductionFor people with type 2 diabetes (T2DM) inadequately controlled with oral antidiabetic drugs (OADs), evidence from both randomized controlled trials (RCTs) and real-world studies has demonstrated that treatment intensification with liraglutide offers effective glycemic control, weight reduction, and a lower risk of hypoglycemia compared to treatment intensification with insulin or additional OADs. Sodium glucose cotransporter 2 (SGLT-2) inhibitors are a new class of OADs that have also been shown to be effective in T2DM patients inadequately controlled with OADs. Currently there are no head-to-head RCTs comparing these to liraglutide.MethodsWe aimed to evaluate the relative efficacy, using network meta-analysis (NMA), of treatment intensification with liraglutide and SGLT-2 inhibitors people with T2DM who have been treated with metformin (alone or in combination with SU, DPP-4, and TZD). We performed a systematic literature review to identify relevant RCTs comparing liraglutide (1.2 and 1.8 mg), canagliflozin (100 and 300 mg), empagliflozin (10 and 25 mg), or dapagliflozin (5 and 10 mg) to placebo. To strengthen the indirect evidence base, we also included non-placebo RCTs where sitagliptin (100 mg) was the active comparator. Bayesian NMA was performed on the following outcomes to assess the relative efficacy and safety of interventions: reduction (change) in HbA1c, weight, and fasting plasma glucose (FPG) as well as proportion reaching target HbA1c (<7%), and risk of hypoglycemia. Doses for each intervention were considered separately.ResultsA total of 16 RCTs were identified. All trials were similar with respect to important baseline characteristics and study design. Both doses of liraglutide were generally statistically significantly superior to the SGLT-2s with respect to change from baseline in HbA1c and FPG as well as odds of reaching target HbA1c <7%. For weight, canagliflozin 300 mg was superior to liraglutide 1.2 mg, and SGLT-2s were generally associated with larger change from baseline in weight. For risk of major or minor hypoglycemia, no differences were found between treatments.ConclusionsCompared to SGLT-2 inhibitors, liraglutide offers improvement in HbA1c and FPG. Reductions in weight are likely comparable between liraglutide and SGLT-2s. Liraglutide did not differ from SGLT-2s in terms of risk of hypoglycemia. Given the lack of head-to-head evidence, this analysis provides valuable insight into the comparative outcomes of liraglutide versus SGLT-2 inhibitors.

Project description: To critically evaluate the efficacy of renin angiotensin system inhibitors (RASi) in patients with coronary artery disease without heart failure, compared with active controls or placebo. Meta-analysis of randomized trials. PubMed, EMBASE, and CENTRAL databases until 1 May 2016. Randomized trials of RASi versus placebo or active controls in patients with stable coronary artery disease without heart failure (defined as left ventricular ejection fraction ?40% or without clinical heart failure). Each trial had to enroll at least 100 patients with coronary artery disease without heart failure, with at least one year's follow-up. Studies were excluded if they were redacted or compared use of angiotensin converting enzyme inhibitors with angiotensin receptor blockers. Outcomes were death, cardiovascular death, myocardial infarction, angina, stroke, heart failure, revascularization, incident diabetes, and drug withdrawal due to adverse effects. 24 trials with 198?275 patient years of follow-up were included. RASi reduced the risk of all cause mortality (rate ratio 0.84, 95% confidence interval 0.72 to 0.98), cardiovascular mortality (0.74, 0.59 to 0.94), myocardial infarction (0.82, 0.76 to 0.88), stroke (0.79, 0.70 to 0.89), angina, heart failure, and revascularization when compared with placebo but not when compared with active controls (all cause mortality, 1.05, 0.94 to 1.17; Pinteraction=0.006; cardiovascular mortality, 1.08, 0.93 to 1.25, Pinteraction<0.001; myocardial infarction, 0.99, 0.87 to 1.12, Pinteraction=0.01; stroke, 1.10, 0.93 to 1.31; Pinteraction=0.002). Bayesian meta-regression analysis showed that the effect of RASi when compared with placebo on all cause mortality and cardiovascular mortality was dependent on the control event rate, such that RASi was only beneficial in trials with high control event rates (>14.10 deaths and >7.65 cardiovascular deaths per 1000 patient years) but not in those with low control event rates. In patients with stable coronary artery disease without heart failure, RASi reduced cardiovascular events and death only when compared with placebo but not when compared with active controls. Even among placebo controlled trials in this study, the benefit of RASi was mainly seen in trials with higher control event rates but not in those with lower control event rates. Evidence does not support a preferred status of RASi over other active controls.

Project description:BackgroundOlder patients with type 2 diabetes mellitus represent a heterogeneous group in terms of metabolic profile. It makes glucose-lowering-therapy (GLT) complex to manage, as it needs to be individualised according to the patient profile. This study aimed to identify and characterize subgroups existing among older patients with diabetes.MethodsRetrospective observational cohort study of outpatients followed in a Belgian diabetes clinic. Included participants were all aged ≥75 years, diagnosed with type 2 diabetes, Caucasian, and had a Homeostasis Model Assessment (HOMA2). A latent profile analysis was conducted to classify patients using the age at diabetes diagnosis and HOMA2 variables, i.e. insulin sensitivity (HOMA2%-S), beta-cell-function (HOMA2%-β), and the product between both (HOMA2%-βxS; as a measure of residual beta-cell function). GLT was expressed in defined daily dose (DDD).ResultsIn total, 147 patients were included (median age: 80 years; 37.4% women; median age at diabetes diagnostic: 62 years). The resulting model classified patients into 6 distinct cardiometabolic profiles. Patients in profiles 1 and 2 had an older age at diabetes diagnosis (median: 68 years) and a lesser decrease in HOMA2%-S, as compared to other profiles. They also presented with the highest HOMA2%-βxS values. Patients in profiles 3, 4 and 5 had a moderate decrease in HOMA2%-βxS. Patients in profile 6 had the largest decrease in HOMA2%-β and HOMA2%-βxS. This classification was associated with significant differences in terms of HbA1c values and GLT total DDD between profiles. Thus, patients in profiles 1 and 2 presented with the lowest HbA1c values (median: 6.5%) though they received the lightest GLT (median GLT DDD: 0.75). Patients in profiles 3 to 5 presented with intermediate values of HbA1c (median: 7.3% and GLT DDD (median: 1.31). Finally, patients in profile 6 had the highest HbA1c values (median: 8.4%) despite receiving the highest GLT DDD (median: 2.28). Other metabolic differences were found between profiles.ConclusionsThis study identified 6 groups among patients ≥75 years with type 2 diabetes by latent profile analysis, based on age at diabetes diagnosis, insulin sensitivity, absolute and residual β-cell function. Intensity and choice of GLT should be adapted on this basis in addition to other existing recommendations for treatment individualisation.
