Abstract Background Insulin resistance (IR), evaluation of which is difficult and complex, is closely associated with cardiovascular disease. Recently, various IR surrogates have been proposed and proved to be highly correlated with IR assessed by the gold standard. It remains indistinct whether different IR surrogates perform equivalently on prognostic prediction and stratification following percutaneous coronary intervention (PCI) in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients with and without type 2 diabetes mellitus (T2DM). Methods The present study recruited patients who were diagnosed with NSTE-ACS and successfully underwent PCI. IR surrogates evaluated in the current study included triglyceride-glucose (TyG) index, visceral adiposity index, Chinese visceral adiposity index, lipid accumulation product, and triglyceride-to-high density lipoprotein cholesterol ratio, calculations of which were conformed to previous studies. The observational endpoint was defined as the major adverse cardiovascular and cerebrovascular events (MACCE), including cardiac death, non-fatal myocardial infarction, and non-fatal ischemic stroke. Results 2107 patients (60.02 ± 9.03 years, 28.0% female) were ultimately enrolled in the present study. A total of 187 (8.9%) MACCEs were documented during the 24-month follow-up. Despite regarding the lower median as reference [hazard ratio (HR) 3.805, 95% confidence interval (CI) 2.581–5.608, P < 0.001] or evaluating 1 normalized unit increase (HR 1.847, 95% CI 1.564–2.181, P < 0.001), the TyG index remained the strongest risk predictor for MACCE, independent of confounding factors. The TyG index showed the most powerful diagnostic value for MACCE with the highest area under the receiver operating characteristic curve of 0.715. The addition of the TyG index, compared with other IR surrogates, exhibited the maximum enhancement on risk stratification for MACCE on the basis of a baseline model (Harrell’s C-index: 0.708 for baseline model vs. 0.758 for baseline model + TyG index, P < 0.001; continuous net reclassification improvement: 0.255, P < 0.001; integrated discrimination improvement: 0.033, P < 0.001). The results were consistent in subgroup analysis where similar analyses were performed in patients with and without T2DM, respectively. Conclusion The TyG index, which is most strongly associated with the risk of MACCE, can be served as the most valuable IR surrogate for risk prediction and stratification in NSTE-ACS patients receiving PCI, with and without T2DM.

Abstract Background Carotid atherosclerosis (CAS) lacks a simple and relatively accurate predictor. Triglyceride glucose (TyG) index is a simple indicator of insulin resistance, but the association between TyG index and CAS in patients with type 2 diabetes mellitus (T2DM) is less certain. This study aimed to investigate whether TyG index can predict CAS onset effectively. Methods In total, 1476 T2DM patients were included in cross-sectional analysis. TyG index (calculated by ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL)/2]) was split into tertiles (Tertile1-Tertile3). The main outcome was CAS prevalence as defined with carotid intima-media thickness (CIMT) ≥ 1.0 mm or carotid plaque. Logistic regression analysis was used to analyze the association between TyG index and CAS in patients with T2DM. Results In cross-sectional analysis, a total of 62.3% of T2DM patients had CAS, patients with a higher TyG index had a higher risk of CAS (χ2 = 13.856, P < 0.01). After confounder adjustment, patients with T2DM in the high tertile of TyG index had a greater risk to developing CAS than those in the low tertile (OR = 1.451, 95% CI =1.107-1.902, P = 0.007). Higher TyG index values were also associated with increased odds of CAS in patients with T2DM who were female, who were younger than 65 years old, who suffered from hypertension or obesity. Conclusion TyG index was significantly associated with CAS, suggesting that TyG index is a potential predictor for CAS in patients with T2DM.

Abstract Background: Triglyceride glucose (TyG) index is considered a reliable alternative marker of insulin resistance and an independent predictor of cardiovascular outcomes. However, the prognostic value of TyG index in patients with type 2 diabetes mellitus (T2DM) and acute myocardial infarction (AMI) remains unclear. Methods: A total of 1932 consecutive patients with T2DM and AMI were enrolled in this study. Patients were divided into tertiles according to their TyG index levels. The incidences of major adverse cardiac and cerebral events (MACCEs), including all-cause death, non-fatal MI, non-fatal stroke, cardiac rehospitalization and revascularization, were recorded. The TyG index was calculated as the ln [fasting triglycerides (mg/dL) ×fasting plasma glucose (mg/dL)/2].Results: Kaplan-Meier curves showed that the incidences of cardiac rehospitalization (p=0.001), revascularization (p<0.001) and composite MACCEs (p=0.027) increased with TyG index tertiles. Multivariable Cox regression models revealed that the TyG index was positively associated with all-cause death, cardiovascular death, cardiac rehospitalization, revascularization and composite MACCEs. The addition of TyG index to a baseline risk model had an incremental effect on the predictive value for composite MACCEs [AUC: 0.663 vs. 0.708, p<0.001].Conclusions: The TyG index was significantly associated with MACCEs, suggesting that the TyG index may be a valid marker for risk stratification and prognosis in patients with T2DM and AMI.Trial registration: retrospectively registered

Introduction: Insulin resistance (IR) and glycemic control are two very important aspects to be considered during management of patients with Type 2 Diabetes Mellitus (T2DM). The triglyceride-glucose (TyG) index has been proposed as a simple and inexpensive parameter that correlates well with IR and glycemic control. Objectives: To explore the association of TyG index (and other TyG derived indices) with glycated hemoglobin (HbA1c) and evaluate their predictive ability for glycemic control in patients with T2DM. Methodology: This cross-sectional study comprised of 160 adult patients diagnosed with T2DM visiting the medical outpatient department of Chitwan Medical College, Bharatpur, Chitwan between July–December 2019. Socio-demographic data and anthropometric measurements were collected. Glycemic control was assessed by HbA1c. TyG index was calculated by the formula: ln [fasting TG (mg/dl) x fasting glucose (mg/dl)/2]. Receiver operating characteristic (ROC) curve analysis was performed to analyze the predictive ability of TyG-index for poor glycemic control. Results: One hundred and sixty patients (mean age: 53.6 ± 10.7 years, 55.0% males) were included in the study. Eighty (50.0%) had good glycemic control (HbA1c <7.0%). TyG index, along with TyG-BMI and TyG-WC (other TyG derived indices) were significantly increased in the poor glycemic control group. TyG index had a good predictive ability for poor glycemic control (AUC: 0.803, 95% CI: 0.731 – 0.874). A TyG cutoff ≥ 9.12 was optimal for predicting poor glycemic control, with 86.1% sensitivity and 61.5% specificity. Conclusion: TyG index could be a simple and cost-effective screening tool for assessment of glycemic control in patients with T2DM.

Abstract Background: Previous studies reported the prognostic value of the triglyceride-glucose (TyG) index in the course of cardiovascular (CV) diseases. Still, it remains unclear whether baseline and trajectories of TyG index are prospectively associated with incident CV events among patients with type 2 diabetes mellitus (T2DM).Methods: We performed a secondary analysis in patients with long-lasting T2DM from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study. The primary outcome was the first occurrence of adverse CV events including nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes, and the TyG index was measured at 11 visits. Cox proportional hazards regression analysis was used to observe the association between baseline and trajectories of TyG index and adverse CV outcomes.Results: During a median follow-up period of 8.8 years, 1,815 (17.8%) developed at least one primary endpoint event. After adjusting for traditional cardiovascular risk factors, each 1-SD increase in the TyG index was associated with a 19.00% higher risk of adverse CV events, similar in individuals categorized by TyG index quartiles. Four distinct trajectories of TyG indexes were identified- low (16.17%), moderate (40.01%), high (34.60%), and very high (9.30%). Among these, moderate, high, and very high TyG index trajectories had a greater risk of future incident adverse CV events than low TyG index trajectories after multivariate adjustments for traditional risk factors. Particularly, a similar association was noticed in the TyG index and the occurrence of coronary heart disease.Conclusions: The findings of this study suggest that both baseline and trajectories of TyG index have a significant association with the occurrence of adverse CV events in patients with T2DM.

Abstract BackgroundTriglyceride-glucose index (TyG index) is associated with type 2 diabetes mellitus (T2DM), but research on this relationship is limited in Obesity population. The purpose of this study was to evaluate the correlation between TyG index and the risk of incident T2DM in Chinese Obesity adult population.Methods80,919 participants with BMI≥ 24 were selected from a prospective cohort study data which was collected between 2010 and 2016 across 32 sites and 11 cities in China.The risk of incident T2DM according to TyG index was estimated using multivariable Cox proportional hazards models and a two-piece wise linear regression model was developed to find out the threshold effect.The formula for TyG index was expressed as ln[fasting triglyceride leve (mg/dL)× fasting plasma glucose level(mg/dL)/2].ResultsAfter follow-up, 3008 ( 3.7%) patients developed T2DM. After adjusting for potential confounders, as a continuous variable, TyG index was associated with an increased risk of incident T2DM (adjusted hazard ratio (aHR), 3.81; 95% confidence interval (95% CI), 3.56-4.09.Further analysis revealed a positive curvilinear association between TyG index and incident T2DM, with a saturation effect predicted at 9.328. When the TyG index was less than 9.328, the risk of incident T2DM increased significantly[HR 4.778 (4.149,5.462), P< 0.001], while the risk became gentle when beyond 9.328[HR 2.61 (2.123,3.209), P< 0.001]. Subgroup analyses showed that the association between TyG index and incident T2DM stably existed in different subgroups.ConclusionsTyG index was a significant predictor of subsequent risk of incident T2DM in Chinese Obesity adult population. An increase in TyG index of one unit increased the risk of developing T2DM by 3.81-fold.

Background: Insulin resistance (IR) is closely associated with the pathogenesis of type 2 diabetes mellitus (T2DM). However, remission of insulin sensitivity after bariatric surgery in patients with T2DM and a body mass index (BMI) of 27.5–32.5 kg/m2 has not been fully elucidated.Methods: Thirty-six T2DM patients with a BMI of 27.5–32.5 kg/m2 were prospectively consecutively recruited for laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG). Hyperinsulinemic euglycemic clamp, oral glucose tolerance test (OGTT), and other indicators were tested at baseline and 6 months postoperative. Glucose disposal rate (GDR), time to reach euglycemia, homeostatic model assessment of IR, quantitative insulin sensitivity check index (QUICKI), triglyceride glucose (TyG) index, 30-min insulinogenic index (IGI30), and disposition index (DI) were calculated at baseline and 6 months after surgery. The criterion for remission in T2DM patients was the achievement of the triple composite endpoint.Results: Anthropometric and glucolipid metabolism parameters significantly improved following surgery. The GDR increased significantly from baseline to 6 months after LRYGB (from 4.28 ± 1.70 mg/kg/min to 8.47 ± 1.89 mg/kg/min, p &lt; 0.0001) and LSG (from 3.18 ± 1.36 mg/kg/min to 7.09 ± 1.69 mg/kg/min, p &lt; 0.001). The TyG index decreased after surgery (RYGB group, from 9.93 ± 1.03 to 8.60 ± 0.43, p &lt; 0.0001; LSG group, from 10.04 ± 0.79 to 8.72 ± 0.65, p = 0.0002). There was a significant reduction in the IGI30 (RYGB group, from 2.04 ± 2.12 to 0.83 ± 0.47, p = 0.005; LSG group, from 2.12 ± 1.73 to 0.92 ± 0.66, p = 0.001). The mean DI significantly increased from 1.14 ± 1.35 to 7.11 ± 4.93 in the RYGB group (p = 0.0001) and from 1.25 ± 1.78 to 5.60 ± 4.58 in the LSG group (p = 0.003). Compared with baseline, HOMR-IR, QUICKI, area under the curve-C-peptide release test (AUC-CRT), and AUC-OGTT were significantly changed at 6 months postoperative. Overall, 52.63% of patients in the LRYGB group versus 29.41% of patients in the LSG group achieved the triple composite endpoint.Conclusion: Both LRYGB and LSG effectively induced remission of IR in patients with T2DM and a BMI of 27.5–32.5 kg/m2.

Hyperuricemia (HU) occurs in one third of patients with type 2 diabetes mellitus (DM 2). The formation of HU in DM 2 is due to metabolic factors and impaired renal function. At the stage of prediabetes, GU reveals a connection with insulin resistance (IR), it is not clear to what extent this phenomenon is associated with an increase in uricemia in DM 2. Direct assessment of IR in patients with DM 2 is difficult. There are methods for indirect estimation of IR based on the calculation of indices using the results of simple laboratory tests. These indices are based on the determination of fasting plasma levels of triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C) — TG/HDL-C, TG and glucose — TyG index, as well as TG, HDL-C and glucose — MI (metabolic index). The aim of the study was to study the relationship in patients DM 2 between the main indicators of uric acid metabolism and the TG/HDL-C index, TyG index, and MI. 368 patients with DM 2 an average age of 55.8 years, and an average disease duration of 7.2 years were examined. There were 147 men, 221 women. The connection of uricemia with TG/HDL-C was established (Rs=0.2, p=0.03). In the non-insulin-dependent course of DM 2, uricemia was positively correlated with TG/HDL-C (Rs=0.21, p=0.03), negative relations of renal clearance of urates with TG/HDL-C (Rs=0.34, p=0.007) and fractional clearance of urates with TyG (Rs =−0.27, p=0.007) were recorded. In the insulin-dependent course of DM 2, a positive association of TyG with uricuria (Rs=0.44, p=0.03) and a negative correlation with GGFRT, the main enzyme for purine reuse (Rs=−0.44, p=0.03), were revealed. The results obtained do not contradict the previously established patterns of uric acid metabolism in DM 2. The conclusion is made on the feasibility of using the TG/HDL-C index as an indicator of metabolic disorders of uric acid and IR in DM 2. In the insulin-dependent course of DM2, TyG index becomes important, an increase in which is associated with increased catabolism of purines and their insufficient reutilization.

The aim of this study was to investigate the associations between the triglyceride-glucose (TyG) index, a marker of insulin resistance, and microangiopathies and macroangiopathies in patients with type 2 diabetes mellitus (DM). Our study enrolled 1990 type 2 diabetic patients from local hospitals in Taiwan during the period of 2002–2004. Multivariate logistic regression analysis was used to identify the factors related to microangiopathies, macroangiopathiess and TyG index. The patients were stratified by TyG index quartile (Q1–Q4). Adjusted odds ratios (aORs) of albuminuria for Q3 versus Q1 and Q4 versus Q1 were 1.424 (95% confidence interval [CI], 1.062–1.910, p = 0.018) and 1.948 (95% CI, 1.437–2.642, p < 0.001), respectively. The aOR of cerebrovascular disease (CVA) was 2.264 for Q4 versus Q1 (95% CI, 1.243–4.122, p = 0.008), but there were no significant associations with diabetic retinopathy (DR), coronary artery disease (CAD) or peripheral artery occlusive disease (PAOD). Significant stepwise increases were found in CVA (p = 0.0013) and albuminuria ≥30 mg/g (p < 0.001) corresponding to TyG index quartiles, but not DR (p = 0.573), CAD (p = 0.880) or PAOD (p = 0.223). There was a significant association between a high TyG index and a high risk of microalbuminuria and CVA in the study cohort. Further studies to investigate the use of medications in patients with DM to prevent micro- and macro-angiopathies are thus warranted.
