Mitochondrial SIRT2-mediated CPT2 deacetylation prevents diabetic cardiomyopathy by impeding cardiac fatty acid oxidation.

Dysregulated energy metabolism, particularly lipid metabolism disorders, has been identified as a key factor in the development of diabetic cardiomyopathy (DCM). Sirtuin 2 (SIRT2) is a deacetylase involved in the regulation of metabolism and cellular energy homeostasis, yet its role in the progression of DCM remains unclear. We observed significantly reduced SIRT2 expression in DCM model mice.

Abnormal skeletal muscle and myocardial vasoreactivity manifests prior to heart failure in a diabetic cardiomyopathy rat model.

Background: Microvascular dysfunction (MVD) is a recognized sign of disease in heart failure progression. Intact blood vessels exhibit abnormal vasoreactivity in early stage, subsequently deteriorating to rarefaction and reduced perfusion. In managing heart failure with preserved ejection fraction (HFpEF), earlier diagnosis is key to improving management.

Mortality predictors in acute myocardial infarction: results from a single-center study in Saudi Arabia.

Acute myocardial infarction (AMI) is a leading cause of morbidity and mortality worldwide. Risk factors of mortality in patients with AMI have been widely investigated, identifying older age and heart failure as common contributors. This study aimed to determine risk factors and explore predictors associated with higher mortality among patients with AMI.

Platelet-to-White Blood Cell Ratio (PWR): A Novel Prognostic Biomarker for Spontaneous Reperfusion after Primary Percutaneous Coronary Intervention.

Background: Spontaneous reperfusion (SR) occurring before primary percutaneous coronary intervention (PPCI) can offer additional clinical benefits to patients with ST-segment elevation myocardial infarction (STEMI). The Platelet-to-White Blood Cell Ratio (PWR) has been recognized as a prognostic indicator in various diseases. We aimed to explore the relationship between PWR and SR in patients with STEMI undergoing PPCI.

The analysis was guided by the updated Consolidated Framework for Implementation Research (CFIR), which informed the resulting themes.

Redo Minimally Invasive Right Atrial Mass Removal After Surgical Atrial Septal Defect Closure.

Atrial septal defects are among the most prevalent congenital anomalies necessitating surgical intervention. Thrombus formation is a recognized complication that is typically characterized by an embolic event following patch-based repair. However, thromboembolic complications following primary repair of atrial septal defects are exceedingly uncommon.

The dataset presented herein encompasses data from five distinct sources, collected in Ljubljana, Slovenia: (a) Questionnaire filled out by all participants for general information, i.

Iron deficiency in acute coronary syndromes: prevalence and prognostic impact.

Introduction And Objectives: Iron deficiency (ID) is a well-known prognostic marker in heart failure (HF), independent of anemia. However, its impact in acute coronary syndromes (ACSs) is not well established.

Methods: This is a retrospective analysis of patients admitted with ACS from January to December 2019.

A Systematic Review Uncovering Modifiable Influences on Statin Adherence.

Statins are effective in reducing cardiovascular disease (CVD) risk, but adherence rates remain low globally. Understanding and addressing modifiable influences on adherence is key to improving outcomes. Existing reviews have methodological limitations, often failing to integrate qualitative and quantitative data or consider specific barriers to statin adherence.

Five-year comparison of clinical and echocardiographic outcomes of pure aortic stenosis with pure aortic regurgitation or mixed aortic valve disease in the COMMENCE trial.

Objective: To compare outcomes of aortic valve replacement (AVR) in patients with pure aortic stenosis (Pure AS) and those with pure aortic regurgitation (Pure AR) or mixed AS and AR (MAVD) in the COMMENCE trial.

Methods: Of 689 patients who underwent AVR in the COMMENCE trial, patients with moderate or severe AR with or without AS (Pure AR + MAVD; n = 135) or Pure AS (n = 323) were included. Inverse probability of treatment weighting Kaplan-Meier survival curves were used for time-to-event endpoints, and longitudinal changes in hemodynamics were evaluated using mixed-effects models.

Association between the proportionality of functional mitral regurgitation and survival after mitral valve operation.

Objective: The concept of proportionate and disproportionate functional mitral regurgitation suggests that transcatheter edge-to-edge mitral repair may benefit patients with a smaller left ventricle relative to a higher regurgitant burden. The clinical relevance of proportionality remains unknown in mitral operations for ischemic mitral regurgitation. We aimed to characterize the association between mitral regurgitation proportionality and outcomes after mitral valve operations.

Fifteen-year experience of direct bridge with venoarterial extracorporeal membrane oxygenation to heart transplantation.

Objective: The study objective was to evaluate outcomes of patients directly bridged with venoarterial extracorporeal membrane oxygenation to heart transplantation.

Methods: A single-center retrospective study was performed on 1152 adult patients undergoing isolated cardiac transplantation between January 2007 and December 2021. Among these, patients bridged with an extracorporeal membrane oxygenation to transplantation (extracorporeal membrane oxygenation group, n = 317) were compared with standard cohorts of patients (no extracorporeal membrane oxygenation group, n = 835).
