Reassessing Revascularization Strategies in Coronary Artery Disease and Type 2 Diabetes Mellitus

ABSTRACT: Percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is still controversial in patients with coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM). Here, we aimed to evaluate the long-term follow-up events of PCI and CABG in these populations. Relevant randomized controlled trials were retrieved from PubMed, Embase, and the Cochrane databases. The pooled results were represented as risk ratios (RRs) with 95% confidence intervals (CIs) with STATA software. A total of six trials with 1,766 patients who received CABG and 2,262 patients who received PCI were included in our study. Patients in the CABG group were significantly associated with a lower all-cause mortality compared with those in the PCI group (RR = 0.74, 95% CI = 0.56–0.98, P = 0.037). Cardiac mortality, recurrent myocardial infarction, and repeat revascularization were also significantly lower in the CABG group (RR = 0.79, 95% CI = 0.40–1.53, P = 0.479; RR = 0.70, 95% CI = 0.32–1.56, P = 0.387; and RR = 0.36, 95% CI = 0.28–0.46, P < 0.0001; respectively). However, compared with the PCI group, the cerebral vascular accident was higher in the CABG group (RR = 2.18, 95% CI = 1.43–3.33, P < 0.0001). There was no publication bias in our study. CABG revascularization was associated with significantly lower long-term adverse clinical outcomes, except cerebral vascular accident, compared with PCI in patients with CAD and T2DM.

Project description:The economic outcomes of clinical management strategies are important in assessing their value to patients.Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) randomized patients with type 2 diabetes mellitus and angiographically documented, stable coronary disease to strategies of (1) prompt revascularization versus medical therapy with delayed revascularization as needed to relieve symptoms and (2) insulin sensitization versus insulin provision. Before randomization, the physician declared whether coronary artery bypass grafting or percutaneous coronary intervention would be used if the patient were assigned to revascularization. We followed 2005 patients for medical utilization and costs and assessed the cost-effectiveness of these management strategies. Medical costs were higher for revascularization than medical therapy, with a significant interaction with the intended method of revascularization (P<0.0001). In the coronary artery bypass grafting stratum, 4-year costs were $80 900 for revascularization versus $60 600 for medical therapy (P<0.0001). In the percutaneous coronary intervention stratum, costs were $73 400 for revascularization versus $67 800 for medical therapy (P<0.02). Costs also were higher for insulin sensitization ($71 300) versus insulin provision ($70 200). Other factors that significantly (P<0.05) and independently increased cost included insulin use and dose at baseline, female sex, white race, body mass index > or =30, and albuminuria. Cost-effectiveness based on 4-year data favored the strategy of medical therapy over prompt revascularization and the strategy of insulin provision over insulin sensitization. Lifetime projections of cost-effectiveness showed that medical therapy was cost-effective compared with revascularization in the percutaneous coronary intervention stratum ($600 per life-year added) with high confidence. Lifetime projections suggest that revascularization may be cost-effective in the coronary artery bypass grafting stratum ($47 000 per life-year added) but with lower confidence.Prompt coronary revascularization significantly increases costs among patients with type 2 diabetes mellitus and stable coronary disease. The strategy of medical therapy (with delayed revascularization as needed) appears to be cost-effective compared with the strategy of prompt coronary revascularization among patients identified a priori as suitable for percutaneous coronary intervention.

Project description:BackgroundCoronary artery disease (CAD) is the leading cause of morbidity and mortality in patients with type 2 diabetes mellitus (T2DM). The purpose of the present study was to discriminate the Indian CAD patients with or without T2DM by using multiple pathophysiological biomarkers.MethodsUsing sensitive multiplex protein assays, we assessed 46 protein markers including cytokines/chemokines, metabolic hormones, adipokines and apolipoproteins for evaluating different pathophysiological conditions of control, T2DM, CAD and T2DM with CAD patients (T2DM_CAD). Network analysis was performed to create protein-protein interaction networks by using significantly (p?<?0.05) altered protein markers in each disease using STRING 10.5 database. We used two supervised analysis methods i.e., between class analysis (BCA) and principal component analysis (PCA) to reveals distinct biomarkers profiles. Further, random forest classification (RF) was used to classify the diseases by the panel of markers.ResultsOur two supervised analysis methods BCA and PCA revealed a distinct biomarker profiles and high degree of variability in the marker profiles for T2DM_CAD and CAD. Thereafter, the present study identified multiple potential biomarkers to differentiate T2DM, CAD, and T2DM_CAD patients based on their relative abundance in serum. RF classified T2DM based on the abundance patterns of nine markers i.e., IL-1?, GM-CSF, glucagon, PAI-I, rantes, IP-10, resistin, GIP and Apo-B; CAD by 14 markers i.e., resistin, PDGF-BB, PAI-1, lipocalin-2, leptin, IL-13, eotaxin, GM-CSF, Apo-E, ghrelin, adipsin, GIP, Apo-CII and IP-10; and T2DM _CAD by 12 markers i.e., insulin, resistin, PAI-1, adiponectin, lipocalin-2, GM-CSF, adipsin, leptin, Apo-AII, rantes, IL-6 and ghrelin with respect to the control subjects. Using network analysis, we have identified several cellular network proteins like PTPN1, AKT1, INSR, LEPR, IRS1, IRS2, IL1R2, IL6R, PCSK9 and MYD88, which are responsible for regulating inflammation, insulin resistance, and atherosclerosis.ConclusionWe have identified three distinct sets of serum markers for diabetes, CAD and diabetes associated with CAD in Indian patients using nonparametric-based machine learning approach. These multiple marker classifiers may be useful for monitoring progression from a healthy person to T2DM and T2DM to T2DM_CAD. However, these findings need to be further confirmed in the future studies with large number of samples.

Project description:Rosiglitazone improves glycemic control for patients with type 2 diabetes mellitus, but there remains controversy regarding an observed association with cardiovascular hazard. The cardiovascular effects of rosiglitazone for patients with coronary artery disease remain unknown.To examine any association between rosiglitazone use and cardiovascular events among patients with diabetes mellitus and coronary artery disease, we analyzed events among 2368 patients with type 2 diabetes mellitus and coronary artery disease in the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial. Total mortality, composite death, myocardial infarction, and stroke, and the individual incidence of death, myocardial infarction, stroke, congestive heart failure, and fractures, were compared during 4.5 years of follow-up among patients treated with rosiglitazone versus patients not receiving a thiazolidinedione by use of Cox proportional hazards and Kaplan-Meier analyses that included propensity matching. After multivariable adjustment, among patients treated with rosiglitazone, mortality was similar (hazard ratio [HR], 0.83; 95% confidence interval [CI], 0.58-1.18), whereas there was a lower incidence of composite death, myocardial infarction, and stroke (HR, 0.72; 95% CI, 0.55-0.93) and stroke (HR, 0.36; 95% CI, 0.16-0.86) and a higher incidence of fractures (HR, 1.62; 95% CI, 1.05-2.51); the incidence of myocardial infarction (HR, 0.77; 95% CI, 0.54-1.10) and congestive heart failure (HR, 1.22; 95% CI, 0.84-1.82) did not differ significantly. Among propensity-matched patients, rates of major ischemic cardiovascular events and congestive heart failure were not significantly different.Among patients with type 2 diabetes mellitus and coronary artery disease in the BARI 2D trial, neither on-treatment nor propensity-matched analysis supported an association of rosiglitazone treatment with an increase in major ischemic cardiovascular events.URL: http://www.clinicaltrials.gov.

Project description:BackgroundNeutrophil extracellular traps NETs have been linked to glucose and the pathogenesis of type 1 diabetes mellitus (T1DM). NETs also play a role in vascular inflammation and the development of coronary artery disease (CAD). The role of NETs in CAD progression in patients with long-term T1DM is unclear. We aimed to 1) investigate whether levels of circulating NETs markers were elevated in long-term T1DM subjects compared to controls, and 2) explore whether levels of NETs were related to the presence of CAD.Material and methods102 patients with > 45 years of T1DM and 75 age-matched controls were enrolled in a cross-sectional study. Median age was 62 years. Computed tomography coronary angiography (CTCA) was performed in 148 subjects without established coronary heart disease. For the current study, CAD was defined as a coronary artery stenosis >50%. Double-stranded deoxyribonucleic acid (dsDNA) was measured by a nucleic acid stain, myeloperoxidase-DNA (MPO-DNA), citrullinated histone 3 (H3Cit) and peptidylarginine deiminase 4 (PAD4) by ELISAs, while gene expression of PAD4 was measured in leukocytes from PAXgene tubes.ResultsCirculating MPO-DNA levels were significantly lower in patients with T1DM than in controls (0.17 vs 0.29 OD, p<0.001), while dsDNA, H3Cit, PAD4 and gene expression of PAD4 did not differ with respect to the presence of T1DM. There were no significant associations between NETs markers and HbA1c in the T1DM group. None of the NETs markers differed according to the presence of CAD in patients with T1DM. While all circulating NETs markers correlated significantly with circulating neutrophils in the control group (r=0.292-393, p<0.014), only H3Cit and PAD4 correlated with neutrophils in the T1DM group (r= 0.330-0.449, p ≤ 0.001).ConclusionsIn this cross-sectional study of patients with long-term T1DM and age-matched controls, circulating NETs levels were not consistently associated with the presence of T1DM or glycemic status, and did not differ according to the presence of CAD in patients with T1DM. Our results entail the possibility of altered neutrophil function and reduced NETosis in T1DM. This warrants further investigation.
