The triglyceride glucose (TyG) index is a marker of insulin resistance. However, the prognostic value thereof in patients with chronic heart failure (CHF) and type 2 diabetes remains unclear.Methods: This study included patients diagnosed with CHF and type 2 diabetes in Fuwai Hospital of Chinese Academy of Medical Sciences, Shenzhen, from January 2017 to July 2019. The primary endpoint was cardiovascular death or rehospitalization for heart failure. Results:The study included 546 patients with CHF and type 2 diabetes. We divided the patients into three groups (T1 [TyG index < 8.55], T2 [TyG index ! 8.55 and < 9.06], and T3 [TyG index ! 9.06]) according to the TyG index level. The incidence of the primary outcome in the T3 group was significantly higher than that in the T1 group. There was no significant difference between the T1 and T2 groups. The trend test revealed a positive correlation between the TyG index and the incidence of the primary outcome (P = 0.001). Conclusions:There is a positive correlation between the TyG index and the prognosis of patients with CHF and type 2 diabetes.

Background: Previous studies have shown that the lactate/albumin (L/A) ratio plays a role in predicting the outcomes of septic shock or severe sepsis. However, the role of the L/A ratio in predicting the outcomes of critically ill patients with heart failure remains unclear. We therefore performed a retrospective study to clarify this issue. Methods:The study was based on the Multiparameter Intelligent Monitoring in Intensive Care III (MIMIC-III) database and included critically ill adult patients with heart failure. The primary endpoints were 28-day and 1-year all-cause mortality after admission at the intensive care unit.Results: We analyzed 4,562 patients in this study. We divided the participants into five groups according to the L/A ratio: quintile (Q)1 (L/A ratio ≤0.40, n=913), Q2 (0.40< L/A ratio ≤0.51, n=912), Q3 (0.51< L/A ratio ≤0.66, n=912), Q4 (0.66< L/A ratio ≤0.92, n=912), and Q5 (L/A ratio >0.92, n=913). After stratifying by L/A ratio, the risk of 28-day and 1-year mortality were significantly different between the groups (log-rank P<0.001). Compared with the first quintile, the second, third, fourth, and fifth quintiles of the L/A ratio were associated with higher 28-day [hazard ratio (HR) 1.57, 95% confidence interval (CI):

BackgroundThere is no consensus at present regarding the differences in the risk of GI bleeding across various NOAC regimens. Therefore, we performed a network meta-analysis to compare the risk of gastrointestinal bleeding after different NOAC regimens.MethodsPubMed, Cochrane, Web of Science, Clinicaltrial.gov and Clinicaltrialresults.org were searched for randomized controlled trials (RCTs) assessing gastrointestinal bleeding of all NOAC regimens from inception to January 2018. The primary endpoint was major gastrointestinal (MGI) bleeding. The meta-regression was performed to access the association between the MGI bleeding events and mortality. The network meta-analysis was carried out with the Bayesian random-effect model.ResultsA total of 25 RCTs, including 139,392 patients, were identified. Meta-regression analysis showed that MGI bleeding was correlated with fatal bleeding events (odds ratios [OR], 1.76; 95% confidence interval [CI], 1.13–2.77], P=0.015). The network meta-analysis results showed that compared to the conventional regimens, rivaroxaban was associated with increased risk of MGI bleeding (OR, 1.37; 95% credible interval [CrI], 1.00–1.85), but not the apixaban (OR, 0.77; 95% CrI, 0.53–1.07]), edoxaban (OR, 0.86; 95%CrI, 0.52–1.18) and dabigatran etexilate (OR, 1.22; 95% CrI, 0.82–1.69). Compared to rivaroxaban, apixaban (OR, 0.56; 95% CrI, 0.35–0.88) and edoxaban (OR, 0.62; 95% CrI, 0.35–0.96) showed a significantly lower risk of MGI bleeding. Apixaban had the highest probability of being the safest option with regard to the risk of MGI bleeding (89.1%), followed by edoxaban (77.4%), conventional therapy (51.4%), dabigatran etexilate (23.8%) and rivaroxaban (8.3%).ConclusionThe risk of GI bleeding significantly varies among different NOAC regimens, and evidence shows that apixaban and edoxaban had the most favorable MGI bleeding safety profile, while rivaroxaban and dabigatran etexilate were the least safe.

Background:With the continuous development of cardiac interventional medicine, the incidence of contrast-induced nephropathy (CIN) is increasing every year, which is a serious threat to people's physical and mental health. Trimetazidine (TMZ) is a type of anti-ischemic drug developed in recent years, which can significantly reduce the incidence of CIN. At present, a systematic review and meta-analysis was conducted to evaluate the clinical effect of TMZ on prevention of CIN in patients with renal insufficiency. However, the study did not include patients from other countries and speaking different languages. So we conducted this study to update the previous meta-analysis that investigated the effects of TMZ on prevention of CIN in patients with renal insufficiency, and provided some theoretical reference for clinical.Methods:By searching PubMed, Embase, the Cochrane Library, Web of Science, CBM, CNKI, VIP database, and Wang Fang database for randomized controlled trial, which is comparing TMZ versus conventional hydration for prevention of CIN. Two researchers independently screened literature, and then evaluated the quality of literature and extracted the relevant data. Stata 11.0 software was used for statistical analysis.Results:Finally, this updated review showed that 3 studies that were not included in the previous meta-analysis were included in our study (3 articles were published in the Chinese Journal, 1 study for CIN, 1 study for CIN, serum creatinine (Scr), and superoxide dismutase, 1 study for CIN and Scr), and 1 outcome (Scr) reflecting the change of renal function was additionally included in our study. Of the 932 studies, 6 randomized controlled trials met the criteria, including 377 patients in TMZ group and 387 patients in control group. This meta-analysis for all studies showed that TMZ can significantly reduce the incidence of CIN (relative risk 0.27, 95% confidence interval [CI] 0.16, 0.46, P = 0.000), and can decrease the level of Scr after operation, including Scr of postoperative 24 hours (standardized mean difference [SMD] −0.30, 95% CI −0.51, −0.09, P = 0.005), Scr of postoperative 48 hours (SMD −0.66, 95% CI −1.23, −0.10, P = 0.022), and Scr of postoperative 7 days (SMD −0.74, 95% CI −1.36, −0.11, P = 0.021). However, the Scr of postoperative 72 hours between TMZ group and control group has no statistical significance (P = 0.362).Conclusion:Our study showed that when comparing with conventional hydration, TMZ can significantly reduce the incidence of CIN and the level of postoperative Scr. Therefore, we could suggest that TMZ was superior to conventional hydration for the treatment of CIN in patients with renal insufficiency. However, due to the restriction of quality and number of included articles, it still needs to carry out multicenter, randomized, double-blind clinical trials to confirm this conclusion in the future.
