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.

Cardiac resynchronization therapy (CRT) improves outcomes in heart failure, but prior interventions like percutaneous mitral annuloplasty may hinder lead placement. We present a 70-year-old male with ischemic cardiomyopathy and severe functional mitral regurgitation who previously received a Carillon device. Due to coronary sinus inaccessibility, left bundle branch area pacing optimized cardiac resynchronization therapy (LOT-CRT) was performed.

Cardiovascular disease (CVD) research is hindered by limited comprehensive analyses of plasma proteome across disease subtypes. Here, we systematically investigated the associations between plasma proteins and cardiovascular outcomes in 53,026 UK Biobank participants over a 14-year follow-up. Association analyses identified 3,089 significant associations involving 892 unique protein analytes across 13 CVD outcomes.

Background: Solid organ transplant (SOT) recipients are not only at increased risk of morbidity and mortality due to acute COVID-19 but may also experience poor long-term outcomes due to post-acute COVID-19 syndromes, including long COVID.
Methods: This retrospective, registry-based chart review evaluated graft failure and mortality among SOT recipients diagnosed with COVID-19 at a large, urban transplant center in Houston, Texas, USA. Patient populations were analyzed separately according to their long COVID status at the time of transplant to preserve the temporal relationship between the exposure (long COVID) and the outcome (graft failure or mortality).

Endovascular mechanical thrombectomy (MT) is a recommended treatment for acute ischemic stroke due to large vessel occlusion (LVO). The objective of the present study was to evaluate the impact of vascular risk factors on the outcome of MT outcomes in patients with stroke with LVO and to determine the prevalence of structural epilepsy in these patients. This was a retrospective cohort study involving patients with stroke between 20 and 80 years of age with LVO who underwent MT.

Background: While psychological stress cannot be dissociated from chronic diseases, the extent to which it impacts the management of chronic diseases is poorly understood. This cross-sectional study investigated the prevalence and impact of psychological stress among Rwandan patients with chronic diseases, particularly hypertension, heart failure, malignancies, diabetes, and kidney failure.
Methods: This cross-sectional study was conducted among internal medicine patients receiving treatment for chronic diseases at the University Teaching Hospital of Kigali (n = 81) and the University Teaching Hospital of Butare (CHUB) (n = 78) between May 1 and June 30, 2024.
