Purpose Of Review: The purpose of this review is to discuss myocardial recovery in heart failure with reduced ejection fraction (HFrEF) and to summarize the contemporary insights regarding heart failure with improved ejection fraction (HFimpEF).
Recent Findings: Improvement in left ventricular ejection fraction (LVEF ≥ 40%) with improved prognosis can be achieved in one out of three (10-40%) patients with HFrEF treated with guideline-directed medical therapy. Clinical predictors include non-ischemic etiology of HFrEF, less abnormal blood or imaging biomarkers, and lack of specific pathogenic genetic variants. However, a subset of patients may ultimately relapse, suggesting that many patients are merely in remission rather than having fully recovered.
Summary: Patients with HFimpEF have improved prognosis but nonetheless remain at risk of relapse and long-term adverse events. Future studies will hopefully chart the natural history of HFimpEF and identify clinical predictors such as blood or novel imaging biomarkers that distinguish subgroups of patients based on differential trajectory and prognosis.

Prognostic Impact of Preoperative Left Ventricular Systolic Dysfunction in Older Adult Patients With Gastric Cancer.
In Vivo

Division of Advanced Surgical Oncology, Research and Development Center for New Medical Frontiers, Kitasato University School of Medicine, Sagamihara, Japan.
Background/aim: The effect of left ventricular systolic dysfunction (LVSD), a risk factor for postoperative mortality, in older adult patients with gastric cancer has not been fully elucidated. This study aimed to evaluate the impact of low preoperative left ventricular ejection fraction (EF) on short- and long-term outcomes in older adult patients with gastric cancer.
Patients And Methods: This retrospective study enrolled 237 older adult patients with gastric cancer (≥75 years old) who underwent preoperative echocardiography and curative gastrectomy.

Background/aim: Atrial fibrillation (AF) and heart failure (HF) commonly co-occur, significantly increasing morbidity and mortality. Poorly controlled AF can contribute to complications like HF and is associated with conditions, such as stroke and pulmonary embolism (PE). This report involves a man with AF who had persistent respiratory symptoms and left-sided chest pain, initially suspected to be PE, but eventually diagnosed as HF.

Background: Coronary artery disease (CAD), primarily caused by atherosclerosis, is a leading cause of death, presenting as angina or myocardial infarction. Advances in cardiac imaging, angiography, and procedures like percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery have improved early detection and management of this condition. This report presents the case of a man who experienced worsening exertional chest pain and discomfort while at rest.

Background: In arrhythmogenic cardiomyopathy (ACM), left ventricle-dominant presentation has poorer outcomes than right-dominant presentation, suggesting that interventricular functional disparity might play a role in patients' prognosis. However, the prognostic impact of ventricular functional discordance in ACM patients remains unknown.
Purpose: To assess whether ventricular functional disparity measured as ventricular discordance index, defined as the ratio of right-ventricular ejection fraction (RVEF) to left-ventricular ejection fraction (LVEF), might reveal prognostic disparities between phenotypes and offer added risk stratification value.

Aims: Patients with cardiomyopathies are a heterogeneous group of patients who experience high morbidity and mortality. Early cardiac assessment and intervention with access to genetic counselling in a multidisciplinary Cardiomyopathy Clinic may improve outcomes and prevent progression to advanced heart failure.
Methods And Results: Our prospective cohort study was conducted at a multidisciplinary Cardiomyopathy Clinic with 421 patients enrolled (42.
