Cardiovascular medicine focuses on the heart and blood vessels, exploring how to prevent, diagnose, and treat conditions that affect our circulation. This vital field ranges from understanding high blood pressure and heart failure to investigating the latest breakthroughs in surgical techniques and lifestyle interventions. Because these discoveries directly impact public health, staying informed about emerging research is more important than ever for both specialists and curious readers.

At Gist.Science, we process every new preprint in this category as it appears on medRxiv, ensuring you have immediate access to the latest findings before they undergo formal peer review. For each study, we provide both a plain-language explanation to clarify the core concepts and a detailed technical summary for those seeking deeper scientific context. Below are the latest papers in cardiovascular medicine, organized to help you navigate the most recent developments shaping the future of heart health.

Efficacy and Safety of Macitentan Across Pulmonary Hypertension Phenotypes: A Systematic Review and Meta-analysis

This systematic review and meta-analysis of 14 studies indicates that macitentan therapy across pulmonary hypertension phenotypes improves specific hemodynamic parameters and reduces mortality, but does not significantly enhance exercise capacity or mean pulmonary arterial pressure, while being associated with higher risks of anemia, peripheral edema, and treatment discontinuation.

Circulating Proteins as Predictors of Improvement in Physical Function in Hospitalized Older Adults with Geriatric Syndromes: Findings from the REHAB-HF Trial

This study demonstrates that baseline levels of specific circulating proteins (GP6, ST2, and ALCAM) can stratify older adults with heart failure into subgroups that derive significantly greater functional benefits from a multidomain physical rehabilitation program compared to an attention control group, although these proteins do not appear to mediate the treatment effect.

Cardiovascular Outcomes in Patients with Type 2 Diabetes and Heart Failure with Reduced Ejection using Glucagon-like Peptide-1 Receptor Agonists

This retrospective cohort study utilizing TriNetX data demonstrates that glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapy is significantly associated with reduced risks of all-cause mortality and major adverse cardiovascular events in patients with type 2 diabetes and heart failure with reduced ejection fraction (HFrEF).

Factors Associated with Adherence to Anti-Hypertensive Medication Among Patients Attending a Primary Health Centre in Ndola, Zambia: A Cross-Sectional Study

This cross-sectional study of 237 hypertensive patients in Ndola, Zambia, reveals a suboptimal medication adherence rate of 41.4% driven by a complex interplay of socio-demographic factors, clinical challenges like side effects and comorbidities, and significant health system barriers including drug stock-outs and transport difficulties.

Automated Identification of Complex Percutaneous Coronary Intervention from Cardiac Catheterization Reports Using Large Language Models

This study demonstrates that high-capacity open-source large language models, particularly Llama 3.3 70B, can accurately and automatically identify complex percutaneous coronary intervention procedures and extract key variables from free-text cardiac catheterization reports, offering a scalable alternative to labor-intensive manual abstraction for cardiovascular research.

Genetically predicted expression of cuproptosis and copper-transport genes and coronary artery disease risk: a cis-Mendelian randomization and colocalization study

This study utilizes cis-Mendelian randomization and colocalization analyses to demonstrate that while cuproptosis and copper-transport genes are upregulated in atherosclerotic plaques, their genetically predicted baseline expression does not causally influence coronary artery disease risk, suggesting their plaque presence is a consequence rather than a driver of the disease.

Ejection fraction on a budget: mapping the accuracy-compute trade space for video-based ejection fraction estimation

This paper systematically maps the accuracy-compute trade-off for video-based ejection fraction estimation by evaluating 22 model configurations, revealing that sparse temporal sampling with specific backbones like R3D-18 or R(2+1)D-18 can significantly reduce computational costs while maintaining expert-level accuracy, thereby providing clear deployment guidance for resource-constrained clinical tools.
