Abstract The impact of sodium-glucose co-transporter 2 inhibitors (SGLT2-i) on reducing the risk of all-cause mortality and rehospitalization for heart failure (HF) in patients with acute myocardial infarction (AMI) remains unclear. This study aims to evaluate the effect of SGLT2-i on all-cause mortality and rehospitalization for HF in patients diagnosed with AMI. A comprehensive search was conducted in PubMed, Web of Science, the Cochrane Library, and Embase for relevant studies published up to May 2024, following the PICOS principle. Eligible studies included randomized clinical trials and cohort studies comparing SGLT2-i with placebo regarding all-cause mortality, rehospitalization for HF, cardiovascular mortality, and the incidence of nonfatal MI in AMI patients. Patient-level data from each trial were synthesized into a pooled dataset and analyzed using a mixed-effects or random-effects model based on the I2 statistic. Ten clinical trials enrolling 15,748 participants (6913 in the SGLT2-i group and 8835 in the placebo group) were included. The follow-up duration ranged from 12 weeks to 2.1 years. SGLT2-i significantly reduced rehospitalization for HF (RR: 0.69, 95% CI 0.60–0.81, P

BackgroundAccurately assessing the postoperative mortality and rehospitalization for heart failure risks in patients undergoing mitral valve repair surgery is of significant importance for individualized medical strategies.ObjectiveWe sought to develop and validate a risk assessment system for the prediction of mortality and rehospitalization for heart failure.MethodsPersonalized risk prediction system of mortality and rehospitalization for heart failure was developed. For developing a prediction system with death as the outcome, there were 965 patients (70%) and 413 patients (30%) were included in the the derivation cohort and the validation cohort. For developing a prediction system with rehospitalization for heart failure as the outcome, there were 927 patients (70%) and 398 patients (30%) were included in the derivation cohort and the validation cohort. There were 42 routine clinical variables used to develop the models. The performance evaluation of the model is based on the area under the curve (AUC). Evaluate the improvement with Euro Score II according to NRI and IDI net reclassification improvement (NRI) and integrated discrimination improvement (IDI).ResultsThe median follow-up time was 685 days, the incidence of death was 3.85% (n = 53), and the incidence of rehospitalization for heart failure was 10.01% (n = 138). The AUC values of the mortality prediction model in the derivation and validation cohorts were 0.825 (0.764–0.886) and 0.808 (0.699–0.917), respectively. The AUC values of the rehospitalization for heart failure prediction model in the derivation and validation cohorts were 0.794 (0.756–0.832) and 0.812 (0.758–0.866), respectively. NRI and IDI showed that the mortality prediction model exhibited superior performance than the Euro Score II. The mortality and rehospitalization for heart failure risk prediction models effectively stratified patients into different risk subgroups.ConclusionThe developed and validated models exhibit satisfactory performance in prediction of all-cause mortality and rehospitalization for heart failure after mitral valve repair surgery.Clinical Trial Registrationhttp://www.clinicaltrials.gov, Unique identifier: (NCT05141292).

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.
