Introduction: Myocardial fibrosis accompanies most cardiac conditions and can be reparative or maladaptive. Transforming Growth Factor (TGF)-β is a potent fibrogenic mediator, involved in repair, remodeling, and fibrosis of the injured heart.
Areas Covered: This review manuscript discusses the role of TGF-β in heart failure focusing on cellular mechanisms and therapeutic implications. TGF-β is activated in infarcted, remodeling and failing hearts. In addition to its fibrogenic actions, TGF-β has a broad range of effects on cardiomyocytes, immune, and vascular cells that may have both protective and detrimental consequences. TGF-β-mediated effects on macrophages promote anti-inflammatory transition, whereas actions on fibroblasts mediate reparative scar formation and effects on pericytes are involved in maturation of infarct neovessels. On the other hand, TGF-β actions on cardiomyocytes promote adverse remodeling, and prolonged activation of TGF-β signaling in fibroblasts stimulates progression of fibrosis and heart failure.
Expert Opinion: Understanding of the cell-specific actions of TGF-β is necessary to design therapeutic strategies in patients with myocardial disease. Moreover, to implement therapeutic interventions in the heterogeneous population of heart failure patients, mechanism-driven classification of both HFrEF and HFpEF patients is needed. Heart failure patients with prolonged or overactive fibrogenic TGF-β responses may benefit from cautious TGF-β inhibition.

Heart failure (HF) remains one of the leading causes of 30-day hospital readmissions, presenting a major challenge to healthcare systems worldwide. This comprehensive review synthesizes recent evidence on effective strategies to reduce readmission rates through patient education, self-care interventions, and systemic reforms. Structured education-particularly when reinforced postdischarge through methods like teach-back, tele-coaching, and home visits-has consistently demonstrated improved self-management, symptom recognition, and quality of life.

Rationale: There are insufficient data to inform the management of central sleep apnea (CSA) in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Nocturnal oxygen therapy (NOT) has been postulated to benefit CSA patients with HFrEF, but has not been rigorously studied.

Clonal hematopoiesis, originally identified as a precursor to hematologic malignancies, has emerged as a significant factor in various nonmalignant diseases. Recent research highlights how somatic mutations in hematopoietic stem cells lead to the expansion of circulating mutated immune cells that exert profound effects on organ function and disease progression. These mutated clones display altered inflammatory profiles and tissue-specific functional consequences, contributing to various diseases including atherosclerotic cardiovascular disease, osteoporosis, heart failure, and neurodegenerative conditions.

Aims: Several diuretic strategies, including furosemide iv boluses (FB) or continuous infusion (FC), are used in acute heart failure (AHF).
Methods And Results: We systematically searched phase 3 randomized clinical trials (RCTs) evaluating diuretic regimens in admitted AHF patients within 48 hours and irrespective of clinical stabilization. We calculated the odds ratio (OR) of FC or FB plus another diuretic (sequential nephron blockade, SNB) compared to FB alone on 24-hour weight loss (WL) and worsening renal function (WRF), with a random-effects model with inverse variance weighting.
