(Press-News.org) WASHINGTON—A new expert opinion from the Society for Cardiovascular Angiography & Interventions (SCAI) examines the evolving role of angiography-derived physiology (ADP), a wire-free method for coronary physiologic assessment that applies computational modeling or artificial intelligence (AI) to standard coronary angiographic images for the assessment and management of coronary artery disease.
Published in JSCAI, “Angiography-Derived Physiology for Coronary Artery Disease Assessment: Expert Opinion from a SCAI Roundtable” provides practical guidance on when and how ADP may be used in clinical practice, what questions it can help answer in the cardiac catheterization laboratory, and where important limitations remain.
“Physiological assessment using pressure wires remains the gold standard for evaluating intermediate coronary lesions, yet utilization is only 10–20 percent. ADP has the potential to address many of these barriers,” said Evan Shlofmitz, DO, Director of Intravascular Imaging at St. Francis Hospital in Roslyn, NY, and chair of the roundtable. “The use of ADP has advanced quickly, and many interventionalists are encountering these tools without a clear framework for interpretation or application. Our goal was to rigorously evaluate the evidence, define where ADP offers meaningful clinical value today, and clearly articulate the limitations and unanswered questions that must be addressed before broader adoption.”
The expert roundtable brought together an international panel to review available ADP platforms, highlight key methodological differences, and define clinical scenarios where the technology may be most useful. These include assessment of multivessel disease, planning and optimization of percutaneous coronary intervention (PCI), post-PCI physiologic evaluation, and evaluation of non-culprit lesions in patients presenting with acute coronary syndromes. The document emphasizes the importance of high-quality angiographic acquisition and appropriate operator expertise, particularly in complex clinical settings.
“Physiology-guided decision-making remains foundational to high-quality coronary intervention, and ADP represents an important technological advance. At the same time, ADP must be applied with a clear understanding of its assumptions, technical requirements, and the strength of the supporting evidence. This expert opinion helps clinicians understand where ADP can responsibly complement wire-based physiology today and where caution and further data remain necessary,” said William F. Fearon, MD, MSCAI, Chief of Interventional Cardiology at Stanford University School of Medicine and the VA Palo Alto Health Care System.
As the technology continues to evolve, the panel underscored the importance of continued technological refinement, careful clinical application, appropriate training, and ongoing outcomes research to ensure successful integration into routine clinical practice.
The expert roundtable was conducted with support from CathWorks and Medtronic.

‘Masculinity crisis’: Influencers on social media promote low testosterone to young men, study finds
2026-02-03
Young men are being encouraged to undergo testosterone testing and start hormone therapy through Instagram and TikTok content that promotes unproven health claims while downplaying medical risks, a new international study has found.
The study was done at the University of Sydney’s Faculty of Medicine and Health, and led by Emma Grundtvig Gram, a visiting PhD student from the University of Copenhagen. It found that influencer marketing on social media is normalising unnecessary testosterone testing ...

Accurately predicting Arctic sea ice in real time
2026-02-03
WASHINGTON, Feb. 3, 2026 — Arctic sea ice has large effects on the global climate. By cooling the planet, Arctic ice impacts ocean circulation, atmospheric patterns, and extreme weather conditions, even outside the Arctic region. However, climate change has led to its rapid decline, and being able to make real-time predictions of sea ice extent (SIE) — the area of water with a minimum concentration of sea ice — has become crucial for monitoring sea ice health.

A hearing test for the world’s rarest sea turtle
2026-02-03
WASHINGTON, Feb. 3, 2026 — Kemp’s ridley sea turtles are among the most endangered species of sea turtles in the world. They reside along the east and Gulf coasts of North America, alongside some of the world’s most active shipping lanes. While the threats from fishing, pollution, and vessel collisions are well understood, it is less clear how disruptive human-caused noise is to their survival.

Estimated effectiveness of 2024-2025 COVID-19 vaccination against severe COVID-19
2026-02-03
About The Study: This multicenter, case-control study found that the vaccine effectiveness of 2024-2025 COVID-19 vaccines was associated with protection against COVID-19 hospitalization and severe in-hospital outcomes and against multiple JN.1 descendants. Monitoring COVID-19 vaccine effectiveness, including stratifying by SARS-CoV-2 lineage and spike protein mutations, remains important to guide COVID-19 vaccine composition and recommendations.

Risk of cardiorespiratory events following RSV–related hospitalization
2026-02-03
About The Study: This study demonstrated that respiratory syncytial virus (RSV), similar to influenza and SARSCoV-2, was associated with an increased risk of cardiorespiratory events 2 weeks following RSV-related hospitalization, and some conditions had significant risk elevations up to 180 days after admission. The findings reinforce the need to increase RSV immunization in adults.

Socioeconomic status and postpartum depression risk by state trigger laws after dobbs
2026-02-03
About The Study: In this cohort study, state-level abortion bans following Dobbs were associated with a disproportionate increase in the risk of postpartum depression among women and adolescents in low- socioeconomic status communities. These findings underscore the need for targeted mental health support and policy interventions to mitigate the unequal burden of such legislation on vulnerable populations.

Shared purpose outperforms specialization, new study shows
2026-02-03
A new study published in the Strategic Management Journal challenges long-standing assumptions about managerial specialization by examining when organizations perform better by having leaders collectively pursue multiple objectives rather than dividing responsibilities among them. Addressing the growing complexity of modern organizations—where financial, social, environmental, and technological goals increasingly coexist—the research introduces what the authors call the “common purpose advantage.”
Drawing on a computational model of multi-manager firms, the study compares performance under two approaches: “objective ...

Risk for Lyme disease in Ohio is equal to Connecticut, study shows
2026-02-03
COLUMBUS, Ohio – The risk for being bitten by a tick infected with bacteria that cause Lyme disease is as high in Ohio as it is for those living in Northeast states that have dealt with Lyme disease for over 50 years, according to a new study.
Researchers followed up on a 2014 study finding that Ohio’s first established population of blacklegged ticks, carriers of the bacteria that cause Lyme disease, had been detected in 2010 in Coshocton County.
At that time, the infectious bacteria were detected in 2.4% of collected blacklegged ticks and antibodies indicating prior exposure to the pathogen were detected in 20% of white-footed mice, ...
