Background. To assess the association of metformin monotherapy with the risk of all-cause deaths and cardiovascular deaths and events in type 2 diabetes patients in real clinical practice. Methods. This retrospective, observational study comprised patients with type 2 diabetes initially treated with metformin or nonmetformin monotherapy over 2011-2016. Data were extracted from the National Healthcare Big Data database in Fuzhou, China. Propensity score matching (PSM) was performed, matching each patient on metformin to one on nonmetformin in terms of a set of covariates. The primary endpoint was all-cause death, and secondary endpoints were cardiovascular death, heart failure, and heart failure hospitalization. Covariate-adjusted associations of metformin use with all the endpoints were assessed by Cox proportional hazards models. Results. Among 24,099 patients, 5491 were initially treated with metformin and 18,608 with nonmetformin. PSM yielded 5482 patients in each cohort. During a median follow-up of 2.02 years, we observed 110 and 211 deaths in the metformin and nonmetformin groups, respectively. Metformin was significantly associated with reduced risk of all-cause death (adjusted hazard ratio (aHR) 0.52, 95% confidence interval (CI) 0.39-0.69), cardiovascular death (aHR 0.63, 95% CI 0.43-0.91), and heart failure (aHR 0.61, 95% CI 0.52-0.73), whereas the reduced risk in heart failure hospitalization was not statistically significant (aHR 0.70, 95% CI 0.47-1.02). Conclusions. In this analysis of electronic health record data from a large database in China, metformin as first-line monotherapy greatly reduced the risk of all-cause death, cardiovascular death, and heart failure in diabetes patients as compared with nonmetformin medications.

AimTo evaluate the impact of sodium glucose cotransporter 2 inhibitors (SGLT-2i) on risk of heart failure hospitalization in patients with type 2 diabetes.MethodsWe searched the PubMed, Embase, The Cochrane Library, CNKI, Wanfang, CBM, and other web knowledge databases for data from randomized controlled trials. We performed statistical analyses by using review Manager (RevMan) 5.3 and STATA 12.0 for meta-analysis.ResultsEight randomized controlled trials that compared SGLT-2i versus placebo met our inclusion criteria and were included in the study. The final meta-analysis included a total of 55,763 type 2 diabetes patients. Compared with placebo, SGLT-2i reduced the risk of heart failure hospitalization (RR, 0.63; 95% CI, 0.53 to 0.74; P < 0.00001), MACE (defined as cardiovascular death, myocardial infarction, or ischemic stroke) (RR, 0.92; 95% CI, 0.86 to 0.98; P < 0.007), cardiovascular death (RR, 0.78; 95%CI, 0.62 to 0.99; P = 0.04) in type 2 diabetes patients. SGLT-2i could reduce the risk of death from any cause (RR, 0.77; 95% CI, 0.59 to 1.01; P = 0.06) without statistical significance in type 2 diabetes patients.ConclusionCompared with placebo, SGLT-2i may reduce the risk of heart failure hospitalization, MACE, and cardiovascular death. Therefore, SGLT-2i may be an ideal choice for type 2 diabetes mellitus patient with heart failure. These results will help inform practitioners, patients, and authorities making appropriate choices in hypoglycemic therapy clinical practice.

Abstract Background To compare the cardiovascular event risk in type 2 diabetes patients newly receiving dapagliflozin vs. empagliflozin. Methods We conducted a retrospective cohort study by analyzing a multi-institutional electronic medical records database (Chang Gung Research Database) in Taiwan and included adult type 2 diabetes patients who were newly receiving sodium–glucose co-transporter 2 (SGLT2) inhibitors from 2016 to 2017. The primary outcome was a composite of cardiovascular death, myocardial infarction, ischemic stroke and heart failure. We followed up patients from initiation of SGLT2 inhibitors until the occurrence of cardiovascular events before December 31, 2018. We performed multivariable Cox proportional hazard modeling, adjusting for patients’ age, sex, laboratory data, co-morbidities, and concomitant medications. Results We identified 12,681 new SGLT2 inhibitor users with a mean age of 58.9 (SD 11.8) years, of whom 43.9% were female and 45.8% were new dapagliflozin users. A total of 10,442 person-years of dapagliflozin use and 12,096 person-years of empagliflozin use were included. Compared to empagliflozin users, new users of dapagliflozin were found to have similar risks for primary composite outcome (adjusted HR: 0.91; 95% CI 0.73–1.14), cardiovascular death (adjusted HR: 0.54; 95% CI 0.14–2.12), myocardial infarction (adjusted HR: 0.77, 95% CI 0.49–1.19) and ischemic stroke (adjusted HR: 1.15; 95% CI 0.80–1.65), but a lower risk of heart failure (adjusted HR: 0.68; 95% CI 0.49–0.95). Conclusion The risk of cardiovascular events was similar between dapagliflozin and empagliflozin new users, but dapagliflozin may have a better outcome in the reduction of heart failure in type 2 diabetes patients. Future prospective studies are required to confirm the findings.

Background and objectivesSitagliptin, a dipeptidyl peptidase-4 inhibitor, is commonly prescribed to patients with type 2 diabetes. As this drug is primarily eliminated by the kidney, a reduced dose is recommended for patients with CKD. Some evidence suggests that sitagliptin is associated with a higher risk of congestive heart failure, particularly at higher doses. We compare the 1-year risk of death or hospitalization with congestive heart failure in patients with CKD newly prescribed sitagliptin at >50 versus ≤50 mg/d.Design, setting, participants, & measurementsThis population-based cohort study included older adults (>66 years) with type 2 diabetes and an eGFR<45 ml/min per 1.73 m2 (but not receiving dialysis) who were newly prescribed sitagliptin between 2010 and 2017 in Ontario, Canada. We used inverse probability of treatment weighting on the basis of propensity scores to balance baseline characteristics. The primary composite outcome was death or hospitalization with congestive heart failure. Secondary outcomes included hospitalization with pancreatitis or hypoglycemia, all-cause hospitalization, and glycemic control. Weighted hazard ratios were obtained using Cox proportional hazards regression, and 95% confidence intervals were obtained using bootstrap variance estimators.ResultsOf 9215 patients, 6518 started sitagliptin at >50 mg/d, and 2697 started sitagliptin at ≤50 mg/d. The 1-year risk of death or hospitalization with congestive heart failure did not differ significantly between groups (79 versus 126 events per 1000 person-years; weighted hazard ratio, 0.88; 95% confidence interval, 0.67 to 1.14); hospitalization with pancreatitis (weighted hazard ratio, 0.98; 95% confidence interval, 0.32 to 3.03) and hypoglycemia (weighted hazard ratio, 1.10; 95% confidence interval, 0.64 to 1.90) also did not differ significantly between groups. Patients starting sitagliptin at >50 mg/d had lower mean glycated hemoglobin concentrations (weighted between-group difference, −0.12%; 95% confidence interval, −0.19 to −0.06) and a lower risk of all-cause hospitalization (weighted hazard ratio, 0.81; 95% confidence interval, 0.66 to 0.98).ConclusionsThe risk of death or congestive heart failure was not higher in older adults with CKD starting sitagliptin at >50 versus ≤50 mg/d.PodcastThis article contains a podcast at https://www.asn-online.org/media/podcast/CJASN/2020_11_25_CJN08310520_final.mp3

BACKGROUND: Few studies have examined the relationship between vitamin D levels and incident cardiovascular events in large well-characterized type 2 diabetes cohorts. METHODS: We performed prospective analyses to determine associations between vitamin D status and vascular endpoints among 936 Veterans Affairs Diabetes Trial (VADT) participants (mean age 59.7 years; 96.7% male; 40.4% minority). 25 (OH)-vitamin D was measured a median of two years after entry into the VADT study and participants were subsequently followed an average of 3.7 years for outcomes. Cox proportional hazard models were used to calculate hazard ratios (HRs) for macrovascular endpoints in relation to vitamin D quartile. The primary composite endpoint included documented myocardial infarction; stroke; death from cardiovascular causes; new or worsening congestive heart failure; surgical intervention for cardiac, cerebrovascular, or peripheral vascular disease; inoperable coronary artery disease; and amputation for ischemic gangrene. RESULTS: On average VADT participants had high cardiovascular risk at entry into the study: 65.3% of the patients recruited were obese, 38.5% had previously had a vascular event, 78.7% had hypertension and 59.5% were using statins. During follow-up, 17.2%, 5.0%, 5.9%, 2.4% and 6.6% of participants had a primary composite endpoint, myocardial infarction, chronic heart failure, cardiovascular death or all-cause death, respectively. After adjusting for age, minority status, treatment arm and history of prior event, individuals in the lowest quartile of vitamin D (i.e., 1 to 15.9 ng/ml) were at similar risk of the primary composite endpoint [HR=1.26 (95% CI: 0.81, 1.96)], myocardial infarction [HR=1.13 (95% CI: 0.53, 2.42)], congestive heart failure [HR=1.44 (95% CI: 0.67, 3.06)], cardiovascular death [HR=0.86 (95% CI: 0.28, 2.63)], and death from any cause [HR=1.04 (95% CI: 0.53, 2.04)] as individuals in the highest quartile of vitamin D (i.e., 29.9 to 77.2 ng/ml). CONCLUSIONS: These data indicate that vitamin D status had no significant impact on the incidence of macrovascular events in a cohort of high-risk veterans with type 2 diabetes mellitus in which traditional risk factors were managed according to current treatment guidelines.

<b>Objective: </b>Obesity and type 2 diabetes are risk factors for cardiovascular diseases and mortality, and that commonly result in weight variabilities. We aimed to investigate the association between body weight variability and risk of major cardiovascular outcomes and mortality in individuals with type 2 diabetes using large-scale, nationwide cohort data on the Korean population. <div><p><b>Research Design and Methods: </b>We enrolled 624,237 individuals with type 2 diabetes who underwent health examinations provided by the Korean National Health Insurance System between 2009 and 2010, with ≥3 body weight measurements within 5 years since enrollment and followed up until the end of 2017. We assessed body weight variability using four indices, including variability independent of the mean (VIM). Multivariable-adjusted Cox proportional hazards regression analysis was performed.</p> <p><b>Results: </b>During the follow-up, 15,832, 25,038, and 44,716 cases of myocardial infarction (MI), stroke, and all-cause mortality, respectively, were recorded. Body weight variability was associated with increased risks of major cardiovascular outcomes after adjusting for confounding variables. Compared with the hazard ratios (HRs) of the lowest quartile group, the HRs (95% CIs) of the highest quartile group of VIM for body weight were 1.15 (1.10–1.20), 1.22 (1.18–1.26), and 1.58 (1.53–1.62) for MI, stroke, and all-cause mortality, respectively.</p> <p><b>Conclusions: </b>Body weight variability was associated with increased risks of MI, stroke, and all-cause mortality in type 2 diabetes patients and may be a predictor of cardiovascular outcomes in such patients. Appropriate interventions to maintain stable weight could positively influence health outcomes in type 2 diabetes patients.</p> </div> <br>

Abstract Aims  Few prospective studies have evaluated sex-specific pattern, natural progression of left ventricular (LV) remodelling, and diastolic dysfunction in patients with type 2 diabetes (T2DM). The aim of this study was to study the sex-specific prevalence, longitudinal changes of LV remodelling, and diastolic dysfunction in patients with T2DM. Further, the prognostic value of diastolic function in women and men was also evaluated. Methods and results  A total of 350 patients with T2DM (mean age 61 ± 11 years; women, 48.3%) was recruited. Detailed echocardiography was performed at baseline and after 25 months. A major adverse cardiovascular event (MACE) was defined as cardiovascular death, heart failure hospitalization, or myocardial infarction. Despite a similar age, prevalence of hypertension and body mass index, women had a higher prevalence of LV hypertrophy and diastolic dysfunction at baseline and follow-up compared with men. A total of 21 patients developed MACE (5 cardiovascular death, 9 hospitalization for heart failure, and 7 myocardial infarction) during a median follow-up of 56 months. Women with diastolic dysfunction had a higher incidence of MACE than those with normal diastolic function but this association was neutral in men. Multivariable Cox-regression analysis indicated that diastolic dysfunction was associated with MACE in women [hazard ratio = 6.30; 95% confidence interval (CI) = 1.06–37.54; P &lt; 0.05] but not men (hazard ratio = 2.29, 95% CI = 0.67–7.89; P = 0.19). Conclusion  LV hypertrophy and diastolic dysfunction, both at baseline and follow-up, were more common in women than men. Pre-clinical diastolic dysfunction was independently associated with MACE only in women with T2DM but was neutral in men.
