RESUMO
BACKGROUND: The association between the triglyceride glucose (TyG) index and the risk of early-onset atherosclerotic cardiovascular disease (ASCVD) events or all-cause mortality in young and middle-aged people is not fully elucidated. METHODS: The present study included 64,489 young and middle-aged people who participated in the 2006 Kailuan Study physical examination. Multivariate Cox proportional hazards models and restricted cubic spline curves were used to assess the association of TyG index with early-onset ASCVD events and all-cause mortality. RESULTS: During a median of 11-year follow-up, 1984 (3.08%) participants experienced at least one ASCVD event and 1,392 (2.16%) participants experienced all-cause death. A higher TyG index was significantly associated with a higher risk of early-onset ASCVD events (HR: 1.61, 95% CI 1.38-1.89) and all-cause mortality (HR: 1.39, 95% CI 1.17-1.65), respectively. For each unit increase in TyG index, the risk of early-onset ASCVD events increased by 20%. In addition, there was a non-linear association between the TyG index and early-onset ASCVD events (P for non-linear < 0.01), and a linear association between TyG index and all-cause mortality (P for non-linear = 0.476). CONCLUSIONS: A higher TyG index is significantly associated with an increased incidence of early-onset ASCVD events and all-cause mortality in a young and middle-aged population from North China.

Background: Rheumatoid arthritis (RA) is a systemic and chronic autoimmune disease that is characterized by persistent joint inflammation. RA patients experience a considerably increased risk of cardiovascular-related morbidity and mortality. The current study investigated the association between triglyceride glucose (TyG) index and major adverse cardiovascular events (MACEs) in a predominantly male cohort of RA patients. Methods: A total of 1613 RA patients (81.53% male) were selected from the Kailuan study. The TyG index was calculated as the logarithmic product of fasting blood triglyceride and fasting blood glucose divided by two. MACEs were defined as the composite of non-fatal myocardial infarctions and non-fatal strokes. Cox proportional hazards analysis was performed to study the association between the TyG index and MACEs. Results: A total of 59 MACEs occurred during the median follow-up time of 5.32 years. Following adjustment for age and gender, analysis by multivariable Cox proportional hazards (model 1) showed that an elevated TyG index was associated with an increased risk of MACEs (quartile 2, hazard ratio (HR): 2.741, 95% confidence interval (CI): 1.220-6.157, p = 0.015; quartile 4, HR: 2.521, 95% CI: 1.074-5.917, p = 0.034). After adjustment for other variables, Cox proportional hazards analysis (model 2) showed that an elevated TyG index was independently associated with an increased risk of MACEs (quartile 2, HR: 2.348, 95% CI: 1.009-5.465, p = 0.048). In addition, subgroup analysis showed a higher TyG index was significantly linked to an increased risk of MACEs in patients aged more than 65 years (quartile 2, HR: 6.048, 95% CI: 1.311-27.908, p = 0.021; quartile 4, HR: 12.074, 95% CI: 1.438-101.358, p = 0.022). Conclusions: The TyG index was associated with an increased risk of MACEs in a predominantly male cohort of RA patients. This index may be helpful for the prediction of MACEs in male patients with RA. Clinical Trial Registration: Registration number in the Chinese clinical trial registry: ChiCTR-TNRC-11001489.
RESUMO
This study aimed to explore the relationship between the trajectory of the triglyceride-glucose (TyG) index and the occurrence of major adverse cardiovascular and cerebrovascular events (MACCE) in patients with atrial fibrillation (AF).This prospective study included 1979 patients with AF, who were initially selected from the Kailuan study. Patients of AF were split into four groups according to the value of TyG index. The clinical endpoint was MACCE, including myocardial infarction and ischemic stroke. Cox proportional hazard models were employed to examine the hazard ratio (HR) and 95% confidence interval (CI) for MACCE in various trajectory groups.The mean age of all patients with AF was 67.65 ± 11.15 years, and 1752 (88.53%) were male. Over a median follow-up duration of 5.31 years, in total 227 MACCE were recorded. MACCE cumulative incidence in Quartile 4 (26.96%) was significantly higher than those in other quartiles (P = 0.023). Multivariate Cox proportional hazards regression analysis showed that a higher TyG index (Quartile 4) was significantly and positively linked to MACCE in patients with AF (P = 0.023, HR: 2.103; 95% CI: 1.107-3.994).The evaluated TyG index is significantly associated with an increased risk of MACCE in patients with AF.

Background: Aspirin (ASA), the mainstay antiplatelet treatment in patients with cardiovascular disease (CVD), has been received by a considerable number of AF patients. This study sought to examine the association between ASA monotherapy and the risk of major adverse cardiac and cerebrovascular events (MACCE) in patients with atrial fibrillation (AF). Methods: A total of 850 patients with AF were identified from a community-based Kailuan study. All patients were assigned to two groups according to their medicine history: an aspirin therapy group (ASA group) (n = 174), and a non-aspirin therapy group (non-ASA group) (n = 676). The clinical endpoints are MACCE, including myocardial infarction (MI), ischemic stroke (IS), and hemorrhagic stroke (HS). Incidence curves for MACCE were plotted using the Kaplan-Meier method, and the Log rank test was used to assess the differences in incidence rates. The hazard ratios (HR) and 95% confidence intervals (CI) for MACCE were analyzed using Cox proportional-hazards analysis regression models. Results: During the 7.2-year follow-up, 30 MACCE occurred in the ASA group, and 101 in the non-ASA group, with a cumulative incidence of 19.88% vs 17.27%, P = 0.511; 3 cases of MI occurred in the ASA group, and 18 cases in the non-ASA group, with a cumulative incidence of 1.78% vs 2.90%, P = 0.305. Twenty-seven cases of IS occurred in the ASA group, and 84 cases in the non-ASA group, with a cumulative incidence of 1.78% vs 2.90%, P = 0.305. Eight cases of HS occurred in the ASA group, and 13 cases in the non-ASA group, with a cumulative incidence of 5.01% vs 2.34%, P = 0.045. Multivariate regression analysis showed that ASA therapy was not associated with MACCE (HR: 1.130, 95% CI: 0.747-1.710, P = 0.562). In addition, ASA therapy was not associated with IS (HR: 1.309, 95% CI: 0.843-2.034, P = 0.231). However, ASA therapy was significantly associated with HS (HR: 2.563, 95% CI: 1.024-6.418, P = 0.044). Conclusion: ASA monotherapy is not associated with a lower risk of ischemic events, while significantly associated with a higher risk of bleeding events. Patients with AF are unlikely to benefit from aspirin monotherapy.
RESUMO
BACKGROUND AND PURPOSE: Triglyceride-glucose (TyG) index has been regarded as a reliable surrogate marker of insulin resistance for predicting cardiovascular outcomes. The current study aimed to explore the associations between TyG index with major adverse cardiovascular events (MACE) in patients with chronic kidney disease (CKD). METHODS/PATIENTS: 13,517 patients with chronic kidney disease (CKD) from the Kailuan study were included. Patients were divided into quartiles according to the TyG index. The outcomes were MACE, including acute myocardial infarction (AMI) and ischemic stroke (IS). The association between TyG index and the risk of MACE was analyzed by Cox regression models. RESULTS: During 13.87-year follow-up, a total 1356 MACEs occurred. Multivariable Cox proportional-hazards analyses showed that a higher TyG index quartile was associated with an elevated risk of MACE. CONCLUSIONS: TyG index is significantly related to MACE in patients with CKD. TyG index can be regarded as a novel predictor of MACE for patients with CKD.
