Role of coronary revascularization in TAVI patients with severe aortic stenosis and CAD

The EuroPCR Course Directors have selected 3 major late-breaking trials that will be presented for the first time during EuroPCR 2026 and are set to impact practice worldwide.

ChatCPR instructor delivers near-perfect CPR guidance in proof-of-concept study

A proof-of-concept JAMA Internal Medicine study found that widely available AI models could deliver many guideline-concordant CPR instructions in simulated out-of-hospital cardiac arrest scenarios. A purpose-built AI agent, ChatCPR, achieved higher checklist-based adherence than baseline AI models and dispatcher-assisted CPR instructions, but prospective real-world validation is still needed.

Pregnancy magnifies heart risk, but age alone does not explain why

A large U.S. cohort-crossover study found that pregnancy and the postpartum period were linked to about a seven-fold higher relative risk of major adverse cardiovascular events compared with patients’ nonpregnant baseline risk. This relative risk increase did not vary by maternal age, suggesting pregnancy broadly amplifies existing cardiovascular risk rather than making older age itself the driver of pregnancy-specific cardiovascular complications.

Wastewater tracking catches hospital fungus before patients show symptoms

A new UNLV-led wastewater surveillance study brings scientists one step closer in the global race to detect and deter skyrocketing cases of a potentially deadly drug-resistant fungus that puts hospital patients at risk of serious blood, heart, or brain infections.

Fatty liver disease linked to higher risk of heart attacks

Researchers at Mass General Brigham Heart and Vascular Institute found that people with hepatic steatosis, commonly called "fatty liver disease," have a higher amount of noncalcified, rupture-prone coronary plaque and face nearly twice the rate of cardiovascular events compared to those without steatosis.

New AI framework maps systemic obesity damage at cellular resolution

Researchers at Helmholtz Munich, the Ludwig Maximilians University Munich (LMU) and collaborating institutions have developed an artificial intelligence (AI) framework that maps disease-related changes throughout the entire mouse body at cellular resolution.

Patient intuition leads to urgent open-heart surgery at NYU Langone Hospital—Brooklyn

Shana Hale, a Brooklyn mother of two and a technology executive, noticed a mild burning sensation in her chest during her daily walks last summer.

Rerouting dead tumor debris enhances cancer immunotherapy outcomes

As tumors outgrow their blood and nutrient supplies, or respond to treatments like chemotherapy and radiotherapy, individual cancer cells die, exposing their internal scaffolds.

Aerobic exercise mitigates nanoplastic damage in female zebrafish

Using female zebrafish as a model, researchers have found that aerobic exercise may influence various connections in the body to lessen the damaging health impacts of environmental nanoplastics.

Vitamin C may reduce cancer-linked digestive chemical reactions

A new study from the University of Waterloo uses mathematical modeling to examine how Vitamin C affects chemical reactions in the digestive system that are linked to cancer development.

Women may face greater cognitive impact from dementia risk factors

Researchers from the University of California San Diego School of Medicine found that women not only experience a higher burden of certain modifiable dementia risk factors, but also appear more vulnerable to their effects on cognitive function.

Biomimetic nanocomposite hydrogel promotes tendon healing and tissue regeneration

The new system, termed KGN@PB@CM, combines several advanced elements. Prussian blue (PB) nanozymes act as potent reactive oxygen species (ROS) scavengers, while kartogenin (KGN)-a small molecule that promotes stem cell migration and tenogenic differentiation-is loaded onto the PB core.

Study links pediatric sedation strategies with later neurocognitive outcomes

A new Penn Nursing study suggests that the specific sedatives used during critical illness in early childhood may have long-term implications for a child's neurocognitive development.

560-610 minutes of exercise a week linked to substantial cardiovascular health benefits

Adults should aim to do between 560 and 610 minutes a week of moderate to vigorous physical activity to achieve a substantial reduction in the risk of heart attacks and stroke, suggest the findings of an observational study published online in the British Journal of Sports Medicine.

Why AI tools need clearer guardrails in high-stakes health research

AI-enabled research tools can accelerate health research, but their data-science roots may clash with epidemiological workflows built around prespecified designs, causal reasoning, bias control, and reproducibility. The article argues that researchers should integrate AI cautiously, using clear workflow boundaries, peer review of AI outputs, and sustained human accountability.
