Walking faster offers a simple solution to age-related frailty

Older adults who are prefrail or frail can increase their walking cadence through structured interventions, leading to significant gains in physical function. A rise in steps per minute was closely linked to meaningful improvements in walking endurance.

AI-powered ECG model outperforms doctors in detecting hidden heart disease

Researchers developed an AI-powered ECG model, EchoNext, that detects structural heart disease with high accuracy across diverse hospitals and patient populations. The model outperformed cardiologists and could identify thousands of undiagnosed cases, potentially transforming cardiac screening.

Muscle-derived vesicles heal damaged cells and reverse disease in new study

Researchers discovered that mitochondria-rich extracellular vesicles (Ti-mitoEVs) from skeletal muscle can deliver healthy mitochondria to damaged cells, restoring energy and promoting tissue repair in mice. The approach reversed acute muscle injury and chronic kidney disease, offering a promising new regenerative therapy.

APOE ε4 variant reveals hidden risk factors beyond Alzheimer’s

Researchers discovered that people carrying the APOE ε4 gene variant share a unique immune-related protein signature across their blood, brain, and cerebrospinal fluid—regardless of neurodegenerative disease diagnosis. This signature reveals a fundamental, disease-independent vulnerability linked to APOE ε4, reframing our understanding of genetic risk in conditions like Alzheimer's, Parkinson’s, ALS, and FTD.

Heart failure and atrial fibrillation at the time of mitral valve repair linked to worse outcomes

Patients with heart failure and atrial fibrillation (AF) at the time of mitral transcatheter edge-to-edge repair (M-TEER) for severe mitral regurgitation are more than twice as likely to die or be rehospitalized for heart failure, compared to patients without AF.

Heart scarring linked to abnormal rhythms in older male endurance athletes

Scar tissue in the heart was associated with abnormal heart rhythms among healthy, long-time male endurance athletes age 50 or older, potentially increasing their risk of sudden cardiac death, according to a small study published today in Circulation: Cardiovascular Imaging, an American Heart Association journal.

Chronic venous insufficiency linked to increased cardiovascular disease and mortality risk

In light of reports from the White House that President Donald J. Trump has been diagnosed with Chronic Venous Insufficiency (CVI), the American Heart Association is sharing important information on the condition and its association with cardiovascular risk factors, disease and increased risk of death.
