 AI learned from cardiologists’ notes, and needed far less labeled ECG dataAI learned from cardiologists’ notes, and needed far less labeled ECG data
 
By teaching an AI system to connect raw heart signals with the clinical insights contained in cardiologists’ reports, researchers tested whether routine ECGs could reveal more with far fewer labeled examples.

A review of clinical trials, observational studies, genetic analyses, and mechanistic research suggests that atrial fibrillation risk may follow a U-shaped relationship with testosterone, increasing at both low and high levels. Evidence on testosterone replacement therapy remains mixed, with researchers calling for prospective studies to determine whether mid-physiological testosterone targets and treatment formulation influence AF risk.

In a nationwide Japanese cohort of more than 86,000 women, higher fish intake before pregnancy was associated with lower odds of early-onset hypertensive disorders of pregnancy, while fish intake during pregnancy showed different associations with late-onset disease, particularly among women who had not previously given birth.

A global analysis of GBD 2023 data found that alcohol-attributable liver cancer mortality increased modestly from 1990 to 2023, while mortality from alcohol-attributable cirrhosis, alcoholic cardiomyopathy, and alcohol use disorders declined.
 
 Single-cell atlas reveals key macrophage subtypes in myocardial infarction
 
Single-cell atlas reveals key macrophage subtypes in myocardial infarctionAnnouncing a new article publication for BIO Integration. Myocardial infarction (MI) is characterized by extensive immune activation and dynamic remodeling of the cardiac microenvironment, in which myeloid cells play critical roles in regulating inflammation and tissue repair.
 
 
 Coronary angiography can be safely delayed after out-of-hospital cardiac arrest without ST elevation
 
Coronary angiography can be safely delayed after out-of-hospital cardiac arrest without ST elevationImmediate coronary angiography did not improve 30-day survival compared with a deferred strategy in patients without an ECG ST-elevation after out-of-hospital cardiac arrest.
 
 
 ACC Quality Summit 2026 to focus on cardiovascular patient care improvements
 
ACC Quality Summit 2026 to focus on cardiovascular patient care improvementsThe American College of Cardiology (ACC) Quality Summit 2026 will take place on September 16-18 in Orlando, connecting the cardiovascular quality improvement community to share ideas, learn from real-world successes and drive measurable improvements in the quality, safety and value of patient care.
 
 
 Strength training shows no added arrhythmia risk in people with arrhythmogenic cardiomyopathy
 
Strength training shows no added arrhythmia risk in people with arrhythmogenic cardiomyopathyPeople living with arrhythmogenic cardiomyopathy (ACM), a heritable heart condition that can significantly increase risks for sudden cardiac death, are advised to avoid high-intensity aerobic exercise.

ACC Latin America 2026 brings together experts to examine the latest cardiovascular scienceThe American College of Cardiology (ACC) and the Colombian Society of Cardiology and Cardiovascular Surgery will host the ACC Latin America 2026 conference on September 17-19 in Medellín, Colombia.
 
 
 ECG-CLIP improves heart disease detection using less labeled data
 
Clinicians often use a medical test called a 12-lead electrocardiogram (ECG) to diagnose heart problems, which uses electrodes placed on the chest and limbs to record the heart's electrical activity.
 
 
 Eye scans detect signs of atrial fibrillation years before diagnosis
 
People with atrial fibrillation have signs of the condition in the retinas of their eyes that can be detected as early as four years before diagnosis, finds a new study led by University College London (UCL) and Moorfields researchers.
