AIMS:This meta-analysis aimed to evaluate the efficacy of sodium-glucose cotransporter-2 (SGLT-2) inhibitors in different types of heart failure (HF).METHODS:Randomized controlled trials (RCTs) comparing SGLT-2 inhibitors with placebo in patients with HF were searched in PubMed, the Cochrane Library database, and clinicaltrials.gov. A random-effects model was used for evidence synthesis. The primary endpoint was cardiac death.RESULTS:We included 13 studies (12 RCTs). In patients with HF with preserved ejection fraction (HFpEF), SGLT-2 inhibitors reduced the composite endpoint of cardiac death or rehospitalization because of HF (HHF) (HR: 0.78, 95% CI: 0.70-0.87, I2 = 0%, P < 0.001) and that of HHF (HR: 0.74; 95% CI: 0.64-0.85, I2 = 0%, P < 0.001) but not that of cardiac death (HR: 1.01, 95% CI: 0.80-1.28, I2 = 23.9%, P = 0.943). In patients with HF with reduced EF (HFrEF), SGLT-2 inhibitors reduced the composite endpoint of cardiac death or HHF (HR: 0.75, 95% CI: 0.69-0.82, I2 = 0%, P < 0.001) and the individual endpoints of cardiac death (HR: 0.84, 95% CI: 0.75-0.95, I2 = 0%, P = 0.007) and HHF (HR: 0.69, 95% CI: 0.62-0.77, I2 = 0%, P < 0.001).CONCLUSIONS:SGLT-2 inhibitors reduced the risk of cardiac death in patients with HFrEF but not in those with HFpEF.

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is an extracorporeal circulation technique that provides circulatory and oxygenation support, and it is currently used in the treatment of cardiogenic shock (CS), pulmonary embolism, cardiac arrest (CA), and other diseases. However, this technology is still associated with high complications and mortality. The use of predictive scores for risk stratification before VA-ECMO will be helpful to screen the optimal benefiting population, make optimal clinical decisions, and allocate medical resources reasonably. At present, there are few reports about predictive scores for VA-ECMO. This article systematically reviewed the predictive performance of various scoring tools [the survival after venoarterial ECMO (SAVE) score, prediction of cardiogenic shock outcome for acute myocardial infarction (AMI) patients salvaged by VA-ECMO (ENCOURAGE) score, model for end-stage liver disease (MELD-XI) score, post-cardiotomy extracorporeal membrane oxygenation (PC-ECMO) score, the predicting mortality in patients undergoing VA-ECMO after coronary artery bypass grafting (REMEMBER) score, predictors of mortality with VA-ECMO for acute massive pulmonary embolism, extracorporeal cardiopulmonary resuscitation (ECPR) score, the hypothermia outcome prediction after extracorporeal life support (HOPE) score] for patients receiving VA-ECMO to provide reference for clinical treatment.

Background: The most favorable gastrointestinal (GI) bleeding safety profile among different types of direct oral anticoagulants (DOACs) remains controversial. This meta-analysis includes the latest studies and aims to compare GI bleeding risk associated with the use of various DOACs. Methods: PubMed, Cochrane library, and clinicaltrial.gov were searched. Randomized control trials (RCTs) evaluating the safety of DOACs were identified. The primary endpoint assessed was major GI bleeding. Results: A total of 37 RCTs were included in the analyses. Based on the traditional meta-analysis, the major GI bleeding risk was different among various DOACs (interactive p-value <.10). Network meta-analysis findings showed that no DOACs increased the risk of major GI bleeding compared with conventional therapy. Furthermore, a 10 mg daily administration of apixaban reduced the major GI bleeding risk more than daily doses of 60 mg edoxaban, ≥15 mg rivaroxaban, and 300 mg dabigatran etexilate. No difference was observed between daily doses of 300 mg dabigatran etexilate, 60 mg edoxaban, and ≥15 mg rivaroxaban. The major GI bleeding risk associated with 30 mg daily dose of edoxaban was lower than with 10 mg daily rivaroxaban, and no differences between daily 5 mg apixaban, 30 mg edoxaban, and 220 mg dabigatran etexilate were observed. Conclusion: Differences in the major GI bleeding risk were observed when various DOACs were compared. Among standard-dose DOACs, apixaban was associated with the lowest degree of major GI risk. Among low-dose DOACs, edoxaban was associated with a lower major GI bleeding risk than rivaroxaban.

To assess whether the current body of accumulated data can give convincing evidence in favor of sodium-glucose transport protein-2 inhibitor (SGLT-2i) in all types of heart failure (HF). We searched for randomized controlled trials contrasting the effectiveness of SGLT-2i to placebo or other hypoglycemic medications on clinicaltrials.gov, PubMed, and the Cochrane Library database. To gauge effect size, hazard ratios (HR) were employed as measurements. The composite outcome of cardiovascular death or hospitalization owing to HF was the primary endpoint. Eleven studies were included. In comparison to the control group, the data demonstrated that SGLT-2i is related with a decreased incidence of composite outcome (HR: 0.77, 95% CIs: 0.73-0.81, I 2 = 0%, P < 0.01), CV death (HR: 0.87, 95% CIs: 0.81-0.94, I 2 = 3%, P < 0.01), all-cause mortality (HR: 0.90, 95% CIs: 0.84-0.96, I 2 = 10%, P < 0.01), and hospitalization due to HF (HHF) (HR: 0.70, 95% CIs: 0.66-0.75, I 2 = 0%, P < 0.01). The trial sequential analysis found strong evidence of a decrease in the incidence of all clinical outcomes with SGLT-2i when compared to the control group. Subgroup analysis demonstrated that the association between SGLT-2i and clinical outcome was independent of population characteristics. We confirm that the present evidence supports the use of SGLT-2i in a wide range of HF patients.Systematic review registration:[https://www.crd.york.ac.uk/prospero/#recordDetails], identifier [CRD42022333279].

BACKGROUND:This pairwise meta-analysis determines the difference in bleeding risks associated with the use of novel oral anticoagulants (NOACs) and aspirin.METHODS:PubMed, the Cochrane Library database, clinicaltrial.gov , and related studies were searched for randomized control trials (RCTs) comparing NOAC and aspirin published between January 1, 2000 and May 10, 2021. The primary endpoint was intracranial hemorrhage (ICH).RESULTS:Eleven studies involving 57,645 patients were included. Compared to aspirin, rivaroxaban (5 mg/day) had a similar risk of ICH, major bleeding, and fatal bleeding; rivaroxaban (10 mg/day) had higher risks of gastrointestinal hemorrhage (OR: 1.41; 95% CI: 1.03-1.94; P = 0.032; I2 = 0%) and a similar risk of ICH, major bleeding, and fatal bleeding; and rivaroxaban (15-20 mg/day) had higher risks of ICH (OR: 3.21; 95% CI: 1.36-7.60; P = 0.008; I2 = 0%), major bleeding (OR: 2.64; 95% CI: 1.68-4.16; P < 0.001; I2 = 0%), and fatal bleeding (OR: 2.26; 95% CI: 1.25-4.08; P = 0.007; I2 = 0%) and a similar risk of gastrointestinal hemorrhage. Bleeding outcomes between other NOACs (apixaban and dabigatran etexilate) and aspirin were not different.CONCLUSIONS:The bleeding risks associated with NOACs depend on drug type and dosage. For ≥15 mg/day of rivaroxaban, the risk of ICH was significantly higher than that with aspirin. However, further studies comparing dabigatran etexilate and apixaban versus aspirin are warranted to draw a definite conclusion.

Background: Acute myocardial infarction (AMI) is associated with a poor prognosis. Therefore, accurate diagnosis and early intervention of the culprit lesion are of extreme importance. Therefore, we developed a neural network algorithm in this study to automatically diagnose AMI from 12-lead electrocardiograms (ECGs). Methods: We used the open-source PTB-XL database as the training and validation sets, with a 7:3 sample size ratio. Twenty-One thousand, eight hundred thirty-seven clinical 12-lead ECGs from the PTB-XL dataset were available for training and validation (15,285 were used in the training set and 6,552 in the validation set). Additionally, we randomly selected 205 ECGs from a dataset built by Chapman University, CA, USA and Shaoxing People's Hospital, China, as the testing set. We used a residual network for training and validation. The model performance was experimentally verified in terms of area under the curve (AUC), precision, sensitivity, specificity, and F1 score. Results: The AUC of the training, validation, and testing sets were 0.964 [95% confidence interval (CI): 0.961-0.966], 0.944 (95% CI: 0.939-0.949), and 0.977 (95% CI: 0.961-0.991), respectively. The precision, sensitivity, specificity, and F1 score of the deep learning model for AMI diagnosis from ECGs were 0.827, 0.824, 0.950, and 0.825, respectively, in the training set, 0.789, 0.818, 0.913, and 0.803, respectively, in the validation set, and 0.830, 0.951, 0.951, and 0.886, respectively, in the testing set. The AUC for automatic AMI location diagnosis of LMI, IMI, ASMI, AMI, ALMI were 0.969 (95% CI: 0.959-0.979), 0.973 (95% CI: 0.962-0.978), 0.987 (95% CI: 0.963-0.989), 0.961 (95% CI: 0.956-0.989), and 0.996 (95% CI: 0.957-0.997), respectively. Conclusions: The residual network-based algorithm can effectively automatically diagnose AMI and MI location from 12-lead ECGs.

Whether fractional flow reserve (FFR) should be available for revascularization in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD) is controversial. We aimed to compare the efficacy of various complete revascularization (CR) regimens for STEMI patients with MVD. The PubMed and Cochrane Library databases and clinicaltrial.gov were searched for the randomized controlled trials (RCTs) comparing the FFR-guided CR, angiography-guided CR, and culprit-only revascularization (COR) strategies in STEMI patients with MVD. A Bayesian random-effect model was employed to synthesize the evidence in network meta-analysis. We used relative risk (RR) and 95% credible interval (CrI) as measures of effect size. The primary endpoint was the composite outcome of all-cause mortality or myocardial infarction (MI). Twelve RCTs were included. Angiography-guided CR showed a lower event rate of the composite outcome (RR, 0.68; 95%CrI, 0.50-0.87), all-cause mortality (RR, 0.75; 95%CrI, 0.55-0.96), MI (RR, 0.63; 95%CrI, 0.43-0.86), and repeat revascularization (RR, 0.36; 95% CrI, 0.24-0.55) compared with COR. Additionally, angiography-guided CR had a lower risk of primary outcome (RR, 0.64; 95%CrI, 0.38-0.94) and MI (RR, 0.58; 95%CrI, 0.31-0.92) than FFR-guided CR. The difference between the FFR-guided CR and COR in terms of composite outcome, all-cause mortality, and MI was similar. Angiography-guided CR was associated with the highest probability of optimal treatment for the primary outcome (98.5%), followed by FFR-guided CR (1.2%) and COR (0.3%). STEMI patients with MVD benefitted more from angiography-guided CR than from FFR-guided CR. However, only one study compared the effectiveness of FFR-guided and angiography-guided PCI; thus, the comparison between FFR-guided and angiography-guided PCI relied on indirect evidence. Therefore, further studies directly comparing the effectiveness of these two CR strategies are warranted.
