Journal: The New England journal of medicine PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41124218 Summary: Belzutifan is a hypoxia-inducible factor 2 alpha (HIF-2 alpha) inhibitor. This medication targets dysregulation of the HIF-2 alpha pathway, which drives most cases of metastatic pheochromocytoma and paraganglioma. It offers antitumor activity for patients with advanced pheochromocytoma or paraganglioma. This phase two international single-group trial included 72 participants with locally advanced disease. Article 2: Lipoprotein(a) and risk of dementia: findings from three cohort studies. Journal: European heart journal PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40824531 Summary: High lipoprotein(a) is a recognized causal risk factor for atherosclerotic cardiovascular disease. This study investigated the association between lipoprotein(a) levels and the risk of Alzheimer’s disease or vascular-related dementia. It analyzed lipoprotein(a) measurements from 539478 individuals across three large cohort studies, including the Copenhagen General Population Study and the Copenhagen City Heart Study. The findings clarify the role of lipoprotein(a) in dementia, especially significant given that lipoprotein(a) lowering drugs are currently in clinical trials. Article 3: Artificial intelligence-enhanced electrocardiography to predict regurgitant valvular heart diseases: an international study. Journal: European heart journal PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40669514 Summary: Artificial intelligence-enhanced electrocardiography (AI-E. C. G.) models were developed to diagnose and predict future moderate or severe regurgitant valvular heart diseases. These regurgitant valvular heart diseases include mitral regurgitation, tricuspid regurgitation, and aortic regurgitation. The A. I. E. C. G. models were developed using a large dataset of 988618 electrocardiogram and transthoracic echocardiogram pairs. This development provides a tool to potentially improve outcomes through earlier intervention for significant valvular heart disease. Article 4: Carbon emission analysis of aortic valve replacement: the environmental footprint of transcatheter vs. surgical procedures. Journal: European heart journal PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40599126 Summary: surgical procedures. A life cycle assessment calculated the carbon emissions associated with open surgical aortic valve replacement (S. A. V. R.) and transcatheter aortic valve replacement (TAVR). The analysis compared procedures performed in the operating room and the cardiac catheterization lab. The total carbon footprint was determined for 10 S. A. V. R. cases, 10 operating room TAVR cases, and 10 cardiac catheterization lab TAVR cases. This study provides a foundational understanding of the environmental footprint of these cr
