glycemic control in CABG

BACKGROUND Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are widely used owing to their effective glycemic control and protective effects against heart and kidney failure. Euglycemic diabetic ketoacidosis (eu-DKA) is a complication of treatment with SGLT2is. Eu-DKA often leads to delayed diagnosis and results in life-threatening complications. We report 2 critical cases of SGLT2i-associated eu-DKA. CASE REPORT Case 1 was 52-year-old woman with unstable angina scheduled for elective coronary artery bypass grafting surgery...

Perioperative hyperglycemia, hypoglycemia, and high glycemic variability are independent risk factors for mortality in critically ill patients. After cardiac surgery, intensive glycemic control without hypoglycemia may help to reduce the number of adverse events; however, postoperative glycemic control is difficult in many cases. In this study, we investigated whether the bedside artificial pancreas STG-55 is useful for postoperative glycemic control in cardiac surgery. METHODS: In the present single-center retrospective study, we analyzed arterial blood glucose levels for 15 h after surgery in 69 patients treated using the bedside artificial pancreas and in 160 patients treated with continuous intravenous insulin infusion using a scale that adjusts for current blood glucose level, glycemic fluctuation, and insulin dose...

BACKGROUND: The purpose of this study was to investigate risk factors of in-hospital mortality and vascular complications after coronary artery bypass grafting (CABG), particularly the effect of different glycemic control levels on outcomes in patients with and without previous evidence of diabetes. METHODS: A total of 8682 patients with and without previous diabetes undergoing CABG were categorized into strict, moderate, and liberal glucose control groups according to their mean blood glucose control level <7...

Background: Many of the patients who are undergoing Coronary Artery Bypass Graft have diabetes mellitus or metabolic syndrome and are at risk for hyperglycemia events. Objective: The present study aimed to compare conventional glucose control with adjusted tight control in patients undergoing on-pump CABG. Methods: This double -blind randomized clinical trial study was conducted in Shiraz, Iran, from September 2017-March 2018. Two consecutive groups of 75 patients undergoing elective on- pump coronary artery bypass graft surgery...

Recent clinical trials have revealed that aggressive insulin treatment has a neutral effect on cardiovascular risk in patients with diabetes despite improved glycemic control, which may suggest confounding direct effects of insulin on the human vasculature. We studied 580 patients with coronary atherosclerosis undergoing coronary artery bypass surgery (CABG), finding that high endogenous insulin was associated with reduced nitric oxide (NO) bioavailability ex vivo in vessels obtained during surgery. Ex vivo experiments with human internal mammary arteries and saphenous veins obtained from 94 patients undergoing CABG revealed that both long-acting insulin analogs and human insulin triggered abnormal responses of post-insulin receptor substrate 1 downstream signaling ex vivo, independently of systemic insulin resistance status...

OBJECTIVE: The Diabetes Control and Complications Trial (DCCT) and its observational follow-up Epidemiology of Diabetes Interventions and Complications (EDIC) demonstrated the dominant role of glycemia, second only to age, as a risk factor for a first cardiovascular event in type 1 diabetes (T1D). We now investigate the association between established risk factors and the total cardiovascular disease (CVD) burden, including subsequent (i.e., recurrent) events. RESEARCH DESIGN AND METHODS: CVD events in the 1,441 DCCT/EDIC participants were analyzed separately by type (CVD death, acute myocardial infarction [MI], stroke, silent MI, angina, percutaneous transluminal coronary angioplasty/coronary artery bypass graft [PTCA/CABG], and congestive heart failure [CHF]) or as composite outcomes (CVD or major adverse cardiovascular events [MACE])...

INTRODUCTION: Diabetes is associated with a higher risk of major adverse coronary events (MACE) following coronary artery bypass grafting (CABG). Guidelines recommend disparate targets for glycemic control of patients with diabetes who have undergone CABG, ranging from a target hemoglobin A1c (HbA1c) of <7.0% to 7.1-8.5%, based on data from non-CABG patients. To date, no study has evaluated the long-term impact of HbA1c concentrations on MACE post-CABG. OBJECTIVE: To evaluate the association between HbA1c and MACE in CABG patients with diabetes...

BACKGROUND: Diabetes mellitus (DM) has been demonstrated to be a strong risk factor for development and perpetuation of atrial fibrillation (AF). However, how DM and glycemic control affect the pathogenesis of AF has not been sufficiently investigated, especially for the atrial structural remodeling. METHODS: A total of 86 patients undergoing coronary artery bypass graft surgery were enrolled in this study, with atrium sample collected in the operation. The patients were divided into the DM group (n = 40) and the control group (n = 46) accordingly...

Background: Diabetes is not uncommon in patients requiring cardiac surgery. These patients have a higher incidence of morbidity and mortality. Subsequently, diabetes represents a major medico-economic problem in both developed and developing countries. This study was designed to observe the association between glycemic control and outcome of patients after open heart surgery in adult population. Materials and Methods: Data was collected retrospectively in all patients who underwent open cardiac surgery (coronary artery bypass grafting, valve, or bypass grafting with valve surgery) and survived 72 hours postoperatively and had diabetes...

BACKGROUND: Elevated preoperative hemoglobin A1c (HbA1c) is a predictor of poor outcomes following coronary artery bypass grafting (CABG), but the role of increased postoperative glucose variability (GV) is unknown. We hypothesized that short-term postoperative GV is associated with an increased risk of postoperative atrial fibrillation following isolated CABG. METHODS: Multicenter retrospective study of 2073 patients who underwent isolated CABG from January 2012 to March 2018...

Background : We report post-coronary artery bypass outcomes and factors affecting the outcomes from the Genesee County, MI, where the population is distinctly characterized by a higher prevalence of renal failure (RF), diabetes, obesity and smoking than the national average. Methods : We performed a retrospective cohort study on 1133 patients undergoing isolated CABG at our hospital from June 2012 to July 2017. Primary outcome was the association between preoperative hemoglobin A1c (HbA1c) and all-cause postoperative mortality after CABG, secondary outcomes included the association between HbA1c and a composite of postoperative infections including sternal-wound infections, leg harvest-site infections, pneumonia or sepsis...

This study was carried out to evaluate the effects of selenium supplementation on glycemic control, lipid profiles, and biomarkers of inflammation and oxidative stress in patients undergoing for coronary artery bypass grafting (CABG) surgery. This randomized, double-blind, placebo-controlled trial was performed among 33 patients undergoing for CABG surgery, aged 40-85 years old. Subjects were randomly allocated into two groups to intake either 200 μg/day selenium supplements as selenium yeast (n = 17) or placebo (n = 16) for 4 weeks...

Background: Triglyceride glucose (TyG) index is a novel marker for metabolic disorders and recently it has been reported to be associated with cardiovascular disease (CVD) risk in apparently healthy individuals. However, the prognostic value of TyG index in patients with stable coronary artery disease (CAD) is not determined. Methods: We conducted a nested case-control study among 3,745 patients with stable CAD. Patients were followed up for 11,235 person-years...

BACKGROUND: A patient's hemoglobin (Hb) A1c level, regardless of diabetic status, is a measure of glycemic control. Studies have found it is an independent predictor of short-term death in patients undergoing coronary artery bypass grafting (CABG). In this study, we used preoperative HbA1c to assess whether levels are associated with short-term and long-term survival after CABG. METHODS: From a regional registry of consecutive cases, we identified 6,415 patients undergoing on-pump isolated CABG from 2008 to 2015 with documented preoperative HbA1c level...

Objective: It is unknown whether adequacy of diabetic control, measured by hemoglobin A1c, is a predictor of adverse outcomes after coronary artery bypass grafting. Methods: From December 2013 to November 2015, 80 consecutive patients underwent primary isolated CABG surgery at national heart institute, their data were prospectively collected and they were classified according to their HbA1c level into two groups, Group (A): Forty patients with fair glycemic control (HbA1c below or equal to 7%), Group (B): Forty patients with poor glycemic control (HbA1c above 7%)...

INTRODUCTION: Postoperative atrial fibrillation (POAF) is a common complication following cardiac surgery associated with increased morbidity and mortality. Although sustained hyperglycemia is a known risk factor of AF and poor ICU outcomes, emerging in-vitro studies reveal acute glycemic fluctuations to be an additional independent predictor of AF. The effect of acute glycemic fluctuations on the incidence of POAF in the clinical setting remains unclear. We aim to investigate the effect of the magnitude of acute perioperative glycemic fluctuations on the incidence of POAF in a multi-ethnic Southeast-Asian population...

Background: The prevalence of diabetes mellitus in patients requiring coronary artery bypass grafting (CABG) is noticeably high (20%-30%). These patients have inferior perioperative outcome, reduced long-term survival, and high risk of recurrent episodes of angina. To improve perioperative outcome surgical unit defined satisfactory glycemic control is desired during this period. Hence, the aim of our study is to compare the efficacy of glargine insulin combination with continuous human insulin infusion for perioperative glycemic control in patients with diabetes undergoing CABG...

Background: Diabetic patients may be more susceptible to myocardial injury after coronary interventions. Thus, the aim of this study was to assess the release of cardiac biomarkers, CK-MB and troponin, and the findings of new late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) in patients with type 2 diabetes mellitus after elective revascularization procedures for multivessel coronary artery disease (CAD). Methods: Patients with multivessel CAD and preserved systolic ventricular function underwent either elective percutaneous coronary intervention (PCI), off-pump or on-pump bypass surgery (CABG)...

PURPOSE: Critically ill patients with hyperglycemia have worse prognosis. The degree to which glycemic control is achieved following CABG surgery and the association with clinical outcomes is not well understood. MATERIALS AND METHODS: We studied patients undergoing higher risk CABG surgery at 55 US hospitals. Good glycemic control was defined as 70-180mg/dL in the first 24h postoperatively. Generalized estimating equations logistic regression models were used to assess the relationship between glycemic control and clinical outcomes after adjusting for baseline characteristics...

AIM: to determine risk factors of early cardiovascular complications after beating-heart coronary artery bypass grafting (CABG) in patients with ischemic coronary disease (IHD) and type two diabetes (D2). MATERIALS AND METHODS: We included into this study 188 patients (mean age 59 years, 85.1% men) with IHD and D2 who underwent off-pump CABG. The following cardiovascular complications (CVC) registered within 7 days after surgery were analyzed: myocardial infarction (MI), stroke/transient ischemic attack (S/TIA), atrial fibrillation (AF)...
