Association of sodium-glucose cotransporter 2 inhibitors with risk of major adverse cardiovascular events in type 2 diabetes patients with acute coronary syndrome: a propensity score‑matched analysis.

This study aimed to investigate the association of sodium-glucose cotransporter 2 inhibitors (SGLT2i) use with cardiovascular (CV) clinical outcomes in type 2 diabetes (T2D) patients with acute coronary syndrome (ACS). Data of T2D patients hospitalized for ACS at Civil Aviation General Hospital from January 2019 to December 2022 were collected. Based on SGLT2i use or not, patients were stratified as SGLT2i group and SGLT2i-free group. A 1:1 nearest-neighbor propensity score-matched (PSM) was performed to adjust for the confounding factors and facilitate the robust comparisons between groups. The first occurrence of major adverse cardiovascular events (MACE) with 1 year follow-up, which consisted of CV death, all cause death, non-fatal myocardial infarction or stroke, coronary revascularization or heart failure readmission, was assessed. Kaplan-Meier analysis and Cox regressions were conducted to evaluate the prognostic significance of SGLT2i use. Subgroup analyses were performed to assess the interaction between subgroups and SGLT2i use. A total of 925 patients were included, and the SGLT2i use increased from 9.9% in 2019 to 43.8% in 2022. 226 pairs were finally matched using the PSM model. During 1 year follow-up period, a total of 110 patients experienced MACE in the matched cohort, with a rate of 24.3%. Survival analyses showed cumulative incidence of MACE, CV death, and heart failure readmission in the SGLT2i group were significantly lower than the SGLT2i-free group. Additionally, the adjusted Cox analyses demonstrated that SGLT2i was associated with a 34.1% lower risk of MACE (HR 0.659, 95% CI 0.487-0.892, P = 0.007), which was primarily driven by a decrease in the risk of CV death by 12.0% (HR 0.880, 95% CI 0.7830.990, P = 0.033), and heart failure readmission by 45.5% (HR 0.545, 95% CI 0.332-0.893, P = 0.016). This MACE preventive benefit was consistent across different subgroups (P interaction > 0.05 for all comparisons). In T2D patients with ACS, there was a clear increasing trend in SGLT2i use. SGLT2i was associated with a significantly lower risk of MACE, driven by the decrease in the risk of CV death, and heart failure readmission. Our study confirmed real-world use and efficacy of SGLT2i in a general T2D population with ACS.

Can SGLT-2 inhibitors improve cardiovascular outcomes and ensure safety for patients with type 2 diabetes and heart failure in Thailand? A real-world multicentre retrospective cohort study.

To assess the real-world effectiveness and safety of sodium-glucose co-transporter-2 inhibitors (SGLT2i) on cardiovascular outcomes in patients with type 2 diabetes mellitus (T2D) and heart failure (HF) and to evaluate the associated risks of adverse events. A retrospective cohort study using propensity score analysis to control confounding variables. Data were collected from the electronic health records of two large tertiary care hospitals in Thailand over a 12-year period (2010-2022). Adults aged 18 years and older with a diagnosis of T2D and HF were included in the study. Patients who received SGLT2i for a minimum of 3 months were compared with those in a non-SGLT2i group. Participants with a diagnosis of HF that preceded their diagnosis of T2D were excluded from the analysis. The primary outcome was heart failure hospitalisation (HFH). Secondary outcomes included non-fatal stroke, non-fatal myocardial infarction (MI), all-cause mortality and adverse events (urinary tract infections, hypoglycaemia and acute kidney injury). A total of 11 758 patients were included in the study, with a median follow-up of 2.44 (IQR: 0.72-5.02) years. After applying inverse probability of treatment weighting, covariates were balanced, ensuring the validity of the treatment effect model's assumptions. SGLT2i use was associated with a 59% reduction in HFH (HR 0.41, 95% CI 0.28 to 0.61), a 54% reduction in stroke (HR 0.46, 95% CI 0.33 to 0.63), a 51% reduction in MI (HR 0.49, 95% CI 0.36 to 0.67) and a 76% reduction in in-hospital all-cause mortality (HR 0.24, 95% CI 0.14 to 0.42). Additionally, SGLT2i use was associated with fewer adverse events, including lower rates of urinary tract infections and hypoglycaemia, compared with the non-SGLT2i group. SGLT2i significantly improved cardiovascular outcomes in patients with T2D and HF in a real-world clinical setting. These findings support the incorporation of SGLT2i in the management of high-risk patients with T2D and HF. Further research is warranted to explore long-term outcomes and barriers to SGLT2i prescription in routine practice.

ECLIPSES: Early initiation of sodium glucose cotransporter-2 inhibitors for cardiovascular protection in patients with type 2 diabetes following acute coronary syndrome and subsequent coronary artery bypass graft surgery.

There is a paucity of data evaluating early initiation of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with diabetes following acute coronary syndrome (ACS) and coronary artery bypass graft surgery (CABG). To describe the efficacy and safety of SGLT2i initiated early after CABG in patients with type 2 diabetes who experienced ACS. This is a retrospective cohort study of patients with type 2 diabetes (T2DM) who experienced ACS and subsequent CABG with follow up at 3 and 12 months. Patients who filled a SGLT2i prescription within 14 days of discharge were allocated to the SGLT2i group and those who did not were included in the no SGLT2i group. The primary efficacy end point was first occurrence of a 4-point Major Adverse Cardiovascular Event (MACE), and the primary safety end point was a composite of hypoglycemia, hypotension, diabetic ketoacidosis, acute kidney injury, and urinary tract infection. Secondary end points included a comparative analysis of the primary outcome, 30-day readmission rates, and subgroup analyses of key populations. A total of 1629 patients were included: 226 received a SGLT2i within 14 days of discharge and 1403 did not. At 12 months, 8.9% and 15.3% of patients experienced MACE in the SGLT2i and no SGLT2i groups, respectively (adjusted Hazard Ratio [aHR] 0.65, 95% confidence interval [CI] 0.41-1.04). The primary safety outcome occurred in 12.0% of the SGLT2i group and 19.1% of the no SGLT2i group at 12 months (aHR 0.68, 95% CI 0.45-1.01). Early initiation of SGLT2i use was not associated with a reduction in MACE in patients with T2DM who experienced ACS and underwent subsequent CABG surgery. However, no apparent safety concerns were identified. Adequately powered trials are required to confirm this finding.

The association between sodium-glucose cotransporter 2 inhibitors and contrast-associated acute kidney injury in patients with type 2 diabetes undergoing angiography: a propensity-matched study.

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been proven to prevent decline in kidney function and failure. Whether SGLT2i affect the risk of contrast-associated acute kidney injury (CA-AKI) remains uncertain. Use of SGLT2i was assessed in consecutive diabetics undergoing coronary angiography (CA) or percutaneous coronary intervention (PCI) from January 2020 to May 2023 at a tertiary hospital in Chongqing, China. Propensity-matched analysis was used to adjust for baseline variables. CA-AKI was defined by the Acute Kidney Injury Network (AKIN) as creatinine increase ≥ 0.3 mg/dl (26.4 μmol/l), or a percentage increase in the serum creatinine level of ≥ 50%. A total of 604 new users of SGLT2i, and 298 chronic users of SGLT2i were matched with non-users. New use of SGLT2i was not associated with an increased incidence of AKIN-defined CA-AKI (OR 1.60; 95% CI 0.97-2.63; p = 0.065), in-hospital new-onset dialysis (OR 0.50; 95% CI 0.09-2.73; p = 0.422), or death (OR 0.55; 95% CI 0.18-1.66; p = 0.289). However, it was associated with a minor (> 25%) creatinine elevation (OR 1.55; 95% CI 1.04-2.30; p = 0.030), a 0.3 mg/dl increase in creatinine (OR 1.66; 95% CI 1.01-2.75; p = 0.048), and CMSC-defined CA-AKI (OR 1.51; 95% CI 1.02-2.24; p = 0.039). By 90 days, there was no evidence creatinine elevation differed between the two groups (p = 0.590). Chronic use of SGLT2i was not associated with AKIN-defined CA-AKI (OR, 0.92; 95% CI 0.41-2.05; p = 0.838). New use of SGLT2i during CA or PCI was not associated with an AKIN-defined CA-AKI, and it did not translate into new-onset dialysis or death during hospital stay. Chronic usage of SGLT2i did not affect creatinine. Further randomized clinical trials are warranted to confirm this finding.

Influence of sodium-glucose cotransporter 2 inhibitors on the triglyceride-glucose index in acute myocardial infarction patients with type 2 diabetes mellitus.

As a novel oral anti-hyperglycemic agent, sodium-glucose cotransporter 2 inhibitors (SGLT2-i) have been demonstrated to improve cardiovascular outcomes in acute myocardial infarction (AMI) patients with type 2 diabetes mellitus (T2DM). However, the mechanism responsible for the beneficial effects remains unclear. Recently, extensive studies have demonstrated a close relationship between elevated fasting triglyceride-glucose (TyG) index and the risk of AMI. Additionally, research has identified that SGLT2-i can reduce the TyG index in T2DM patients. However, it remains ambiguous whether the benefit of SGLT2-i in patients with AMI and T2DM is due to an improvement in the TyG index. Consequently, we aimed to assess the impact of SGLT2-i on the TyG index in AMI patients with T2DM. A retrospective and cross-sectional study was conducted on 180 AMI patients with T2DM admitted to the chest pain center of the Second Affiliated Hospital of Anhui Medical University from January 2020 to January 2023. Based on the hypoglycemic regimens administered after admission, the patients were categorized into a control group (79 cases treated with sulfonylureas, α-glycosidase inhibitors, metformin, etc.) and a SGLT2-i group (101 cases administered with dapagliflozin or empagliflozin). Propensity score matching (PSM) was adopted to balance the baseline characteristics of patients and minimize selection bias to confirm the robustness of the results. After PSM, control group remained 32 patients, and SGLT2-i group remained 37 patients. All patients underwent regular follow-up after discharge, and comparisons were made between the two groups in terms of clinical indicators and major adverse cardiovascular events (MACEs) in 1 year. Univariate and Multivariate Cox regression analysis was performed to identify the predictors of MACE. Significant differences were observed between the two groups in terms of various parameters before PSM, included age, proportion of insulin use, Gensini score, serum creatinine (Cr), total cholesterol (TC), and cardiac troponin I (cTnI). After PSM, there were no statistically significant differences in baseline clinical indicators and laboratory tests. The median follow-up period was 11 months in both cohorts. The comparison of follow-up results between the two groups after matching confirmed statistically significant differences in triglyceride (TG) reduction index reduction, left ventricular end-diastolic diameter (LVDD) reduction, and white blood cell (WBC) reduction in the SGLT2-i group (all P<0.05). Additionally, a higher incidence of MACEs was observed in the control group (P=0.01). Univariate analysis showed that usage of SGLT2-i, Cr, low-density lipoprotein cholesterol (LDL-C), TyG index at baseline, and changes of TyG index (TyG at follow-up minus TyG at baseline) were associated with the risk of MACE. However, multivariate analysis showed only usage of SGLT2-i was associated with the risk of MACE [hazard ratio (HR) =0.077; 95% confidence interval (CI): 0.009-0.682; P=0.02]. In AMI patients with T2DM, the use of SGLT2-i was associated with a lower risk of MACE and an improvement of TyG index during 11 months follow-up. Our findings offer new insights into the cardio-protective mechanisms of SGLT2-i in the context of AMI.
