The early addition of a sodium–glucose cotransporter 2 (SGLT2) inhibitor to standard treatment may delay or prevent progressive adverse remodelling in these patients.Methods and resultsWe performed a randomized, double‐blind, placebo‐controlled, multicentre trial using cardiovascular magnetic resonance imaging (MRI), in patients with left ventricular systolic dysfunction following MI. Eligible patients were those ≥12 h and ≤14 days following acute MI, with an LVEF <45% by MRI. Patients were randomized to empagliflozin 10 mg once a day or matching placebo. The primary outcome was the change in left ventricular end‐systolic volume indexed to body surface area (LVESVI) from baseline to 24 weeks. Secondary outcomes included measures of left ventricular and atrial volumes, left ventricular mass, LVEF, and high‐sensitivity troponin I (hs‐TnI) and N‐terminal prohormone of B‐type natriuretic peptide (NT‐proBNP) concentrations. From October 2022 to January 2024, 105 eligible patients were randomized. The mean age was 63 ± 11 years and 90 (87%) were male. The mean LVEF was 34.8 ± 6.0%. In the placebo group, LVESVI decreased by 7.8 ± 16.3 ml/m<jats:sup>2</jats:sup>, left ventricular end‐diastolic volume index (LVEDVI) did not change (−0.3 ± 18.7 ml/m<jats:sup>2</jats:sup>) and LVEF increased by 8.5 ± 7.4% at 24 weeks from baseline. Empagliflozin did not affect the change in LVESVI from baseline to 24 weeks (between‐group difference = 0.3 ml/m<jats:sup>2</jats:sup>, 95% confidence interval −5.2 to 5.8; <jats:italic>p</jats:italic> = 0.92). Compared with placebo, empagliflozin also had no effect on LVEDVI, LVEF, left atrial volume index, left ventricular mass index, NT‐proBNP, or hs‐TnI, but did increase haematocrit and reduced uric acid and weight.ConclusionsIn patients with left ventricular systolic dysfunction after an acute MI receiving contemporary standard of care, treatment with empagliflozin had no effect on cardiac volumes or LVEF compared with placebo. Progressive adverse cardiac remodelling did not occur in the majority of patients.","PeriodicalId":164,"journal":{"name":"European Journal of Heart Failure","volume":"75 1","pages":""},"PeriodicalIF":18.2,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In acute heart failure caused by VHD, symptoms result from rapid haemodynamic changes and subsequent decline in cardiac function, and if left untreated, leads to acute decompensation and cardiogenic shock. Current evidence remains scarce and recommendations regarding the management of acute heart failure caused by VHD are lacking in most recent international guidelines. Herein, we review the management of acute heart failure caused by VHD with a focus on transcatheter therapies and describe currently available evidence based on a systematic literature search on the following valve pathologies: (i) aortic stenosis, (ii) aortic regurgitation, (iii) mitral regurgitation, and (iv) mitral stenosis. Articles reporting outcomes following urgent or emergent valve intervention in the setting of cardiogenic shock or acute heart failure were considered. After screening a total of 2234 articles, 76 published between 1994 and 2023 were included in subsequent analysis. Based on available evidence, proposed treatment algorithms to guide optimal management of acute heart failure caused by VHD were created. As the number of patients presenting with acute heart failure caused by VHD continues to rise and outcomes following transcatheter valve interventions continue to improve, it is inevitable that minimally invasive options will play an increasingly important role in the acute setting, especially given these patients are at an increased operative risk. This review aims to present an organized approach to the complex management and interventional treatment of patients with acute heart failure caused by VHD.","PeriodicalId":164,"journal":{"name":"European Journal of Heart Failure","volume":"1 1","pages":""},"PeriodicalIF":18.2,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
