People who later experienced persistent shortness of breath or fatigue after a SARS-CoV-2 infection were already taking significantly fewer steps per day and had a higher resting heart rate before contracting the virus, according to a study by the Complexity Science Hub (CSH) published in npj Digital Medicine. This may indicate lower fitness levels or pre-existing conditions as potential risk factors.
Scientists have successfully tested a rapid, reliable method for assessment of heart disease risk.
The method can measure 25 important markers in the blood simultaneously, such as cholesterol, in less than 15 minutes using radio waves. This new application (currently research use only) could support more patients or people from the general population, in more locations – including regional and remote areas - to access prompt diagnosis and earlier treatment. Science is moving closer to integrating advanced molecular diagnostics into routine healthcare and preventive medicine.
The Journal of the Society for Cardiovascular Angiography & Interventions (JSCAI) proudly announces the publication of a groundbreaking special issue: The Role of Artificial Intelligence in Cardiovascular Interventions.
This issue explores how artificial intelligence (AI) is revolutionizing interventional cardiology, from diagnostic precision to procedural planning and patient outcomes. It features a collection of original research, reviews, and viewpoints that delve into AI’s applications across various subspecialties, including coronary interventions, structural heart disease, congenital heart disease, and cardiovascular imaging.
The incidence of babies born with serious heart defects, known as cyanotic congenital heart disease (CCHD), rose in states that enacted restrictive abortion laws following the U.S. Supreme Court’s 2022 ruling that put abortion laws in the hands of the states, according to a study being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25).
Marijuana is now legal in many places, but is it safe? Two new studies add to mounting evidence that people who use cannabis are more likely to suffer a heart attack than people who do not use the drug, even among younger and otherwise healthy adults. The findings are from a retrospective study of over 4.6 million people published in JACC Advances and a meta-analysis of 12 previously published studies being presented at the American College of Cardiology’s Annual Scientific Session (ACC.25).
