Physics-informed AI framework improves aortic aneurysm stress prediction

Ascending thoracic aortic aneurysms often progress silently, but once dissection or rupture occurs, they can cause severe mortality before hospital arrival or during admission.

Deep-learning tissue clocks reveal how organs age and leave disease-linked signals in blood

Deep learning applied to more than 25,000 histopathology slides revealed tissue-specific structural signatures of biological aging that tracked telomere attrition, pathology, comorbidity, and molecular changes more closely than chronological age alone.

Accumulation of somatic mutations drives vascular damage in people with progeria

Hutchinson-Gilford progeria syndrome (HGPS) is a genetic disorder that causes remarkable premature aging.

Two heart nerve cell types sustain cardiac stability in mice

Researchers identified two major intrinsic cardiac neuron populations in mice: Npy-positive neurons regulate parasympathetic heart rate control and support coronary perfusion, while Ddah1-positive neurons help maintain electrical stability during extreme stress. Removing Npy-positive neurons caused fatal cardiac failure, whereas loss of Ddah1-positive neurons increased susceptibility to malignant arrhythmias and sudden cardiac arrest under stress.

Study: Aortic dissection survivors can participate in moderate‑intensity exercise at home

A multicenter clinical trial led by UTHealth Houston has found that survivors of aortic dissection can participate in moderate‑intensity exercise at home without increasing the risk of recurrent aortic events.

Landmark study confirms long-term durability of Ross procedure for aortic valve replacement

The Ross procedure, a highly specialized option for aortic valve replacement, is associated with significant long-term durability and excellent outcomes in a wide range of adult patients with aortic valve disease.

New PET imaging tracks tumor progression and cardiac inflammation during cancer therapy

A novel PET imaging approach enables simultaneous visualization of tumor progression and cardiac inflammatory responses during cancer treatment.

Active brown fat may protect heart health in obese individuals

People with obesity face a significantly increased risk of atherosclerosis, and consequently heart attack and stroke.

Genetic research identifies rare DNA changes causing common heart valve defect

New clues from genetic research may help explain what causes the most common heart defect present at birth.

Common osteoporosis drugs could slow or halt aneurysm progression

Aortic aneurysms are characterized by abnormal enlargement of the aorta, the primary artery responsible for carrying blood from the heart. Rupture often leads to sudden death, and currently, no effective drug therapies are available to halt disease progression.

Targeted therapy treats mixed histiocytosis following multiple skull relapses

Mixed histiocytosis (Langerhans cell histiocytosis [LCH] / Erdheim-Chester disease [ECD]) developing after treatment for initial skull LCH is not well recognized.

Trial shows mavacamten benefits adolescents with obstructive heart condition

Adolescent patients with obstructive hypertrophic cardiomyopathy (HCM) who received the drug mavacamten saw a significant improvement in left ventricular outflow tract (LVOT) gradient, a measure of blood flow obstruction in the heart, compared with those who received a placebo, according to a small study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Temporary heart pump before PCI shows no significant benefit

The first randomized trial to test whether adding a small, temporary pump to allow the heart to rest and intentionally delaying percutaneous coronary intervention (PCI), also known as coronary angioplasty, for 30 minutes to reduce heart damage compared with standard immediate PCI in patients with heart attacks at risk for a large amount of heart damage found no significant difference between the two groups, the study's primary endpoint. The research was presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

UK air ambulance critical care expands but unequal access still limits lifesaving treatment

A national UK survey found physician-based helicopter emergency medical services have expanded substantially since 2009, with more teams and improved overnight coverage. However, geographic and time-of-day disparities persist, and variation in funding, staffing, and interventions continues to affect equitable access to advanced prehospital care.

UK air ambulance availability improves yet critical gaps continue

Despite significant improvements in the availability of 24/7 emergency air ambulance services (HEMS) across the UK since 2009, persistent regional gaps remain, finds research published online in Emergency Medicine Journal.

Simpler hemiarch surgery effective for older aortic dissection patients

Ascending aortic hemiarch reconstruction offers the same long-term benefits to patients over age 65 with acute type A aortic dissection (ATAAD) as more complex extended arch reconstruction procedures, according to a study presented today at the 2026 Society of Thoracic Surgeons Annual Meeting.
