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.

Lifetime estrogen exposure linked to improved brain health in women

Researchers from the University of Kansas have shown a link between reproductive hormone exposure throughout life and brain health in 459 women aged 65 to 80.

Aligned heart rates indicate real-world social connection and engagement

When people are close-both physically and emotionally-their heart rates begin to align, rising and falling together. Could such cardiac alignment be used as a way to measure social engagement and connection in everyday settings? Hanlu He and colleagues used data collected by 72 students visiting New York City as part of an audio engineering competition.

The menstrual cycle changes heart-rate variability but not strength

Menstrual cycle phases influence heart autonomic regulation, showing HRV variations, yet muscle performance and mood states remain largely unchanged.

Trial identifies 4 grams a day as the tested safe level for L-tyrosine in healthy men

A randomized, crossover trial in healthy adult men found that 4 weeks of L-tyrosine supplementation at doses up to 4 g/day did not cause clinically meaningful changes in safety markers, diet, blood pressure, or body measures. The highest tested dose, 4 g/day, was identified as the no-observed-adverse-effect level under the study’s four-week conditions, although broader and longer-term studies are still needed.

Hyperemesis gravidarum increases risks for pregnancy and birth complications

Pregnant women with a severe form of nausea face increased risks for several pregnancy and birth complications, according to a new Stanford Medicine study of 2.5 million California births.

Statins may trigger muscle side effects by activating inflammatory danger signals

An experimental study in Science Advances shows that statins, primarily fluvastatin in these experiments, may promote low-level muscle myopathy by reducing isoprenoid-dependent protein prenylation rather than by cholesterol lowering. In primed muscle cells and mouse models, impaired YAP signaling, reduced glycolysis, NLRP3/caspase-1 activation, and nuclear FOXO accumulation increased atrogin-1, reduced protein synthesis, and weakened muscle function.

Scientists trace cardiac aging to a fading regulator in heart muscle cells

Researchers mapped 442,239 single nuclei from nonfailing human hearts to chart how cardiac cells change from fetal development to older adulthood. The study identified PRDM16 as an age-declining cardiomyocyte regulator, with experimental evidence showing that restoring Prdm16 in aged mouse hearts improved systolic function and partly reversed aging-associated transcriptional patterns.

Optimized proximity labeling platform tracks cellular protein communication networks

The body's organs are in constant communication. Fat tissue tells the liver when to store or release energy, the immune system signals localized inflammation, and thousands of proteins carry these messages to organs throughout the body.

New global effort aims to improve emergency cardiovascular care

Heart disease, stroke and other life-threatening emergencies remain leading causes of death worldwide, highlighting the need for stronger, more coordinated global systems of care.

Mount Sinai study connects social determinants of health to disease risks

A new study from the Icahn School of Medicine at Mount Sinai shows that social determinants of health-including environmental conditions, health behaviors, access to resources, and social well-being-can play an equally important or even greater role than genetics in predicting a person's risk of developing common diseases.

Sugary drinks from childhood linked to adult hypertension risk

Drinking fruit juice and sugar-sweetened beverages from childhood through adulthood may be linked to an increased risk of developing high blood pressure as an adult, according to new research published today in the American Heart Association's flagship journal Circulation.

International survey highlights major gaps in cardio-oncology education

An international survey has highlighted major gaps in cardio-oncology training, despite its increasing clinical importance. These results were presented at ESC Cardio-Oncology 2026, the second annual conference of the European Society of Cardiology's Council of Cardio-Oncology.

Estradiol changes may shape how much women move during the menstrual cycle

A 28-day wearable-sensor study of 26 healthy naturally menstruating women found that active energy expenditure varied across the menstrual cycle and was higher in the early follicular phase than the late follicular phase.

Heart failure treatments protect heart function during cancer therapy

The cardioprotective effects of heart failure treatments in patients with cancer were demonstrated today in a presentation at ESC Cardio-Oncology 2026, the annual conference of the European Society of Cardiology's Council of Cardio-Oncology.

Sugary chewing gum may temporarily enhance beetroot's blood pressure benefits

For the first time, researchers at King's College London have discovered a link between chewing sugary gum after consuming vegetables high in nitrate, such as beetroot, spinach and kale, on lowering blood pressure.

New mRNA vaccine shrinks neuroblastoma tumors in preclinical study

A new study from RCSI University of Medicine and Health Sciences demonstrates a novel approach in anticancer vaccine development. Results present the first preclinical evidence to show the efficacy of an mRNA vaccine in targeting neuroblastoma, the deadliest childhood cancer.

Caregivers experience food insecurity during hospitalization of sick children

Researchers at Wake Forest University School of Medicine found caregivers of children hospitalized for cancer and blood disorders may experience food insecurity during their child's stay, even if they don't face that issue at home, and it could be linked to longer stays.

Epigenetic drugs improve blood vessel health in obesity and diabetes

People with obesity and type 2 diabetes are at high risk of blood vessel damage. This risk depends not only on the genes a person carries, but also on how they are "read".

New biological age tools could reveal health risks before symptoms appear

A JCI review traces biological age measurement from functional tests and blood biomarkers to epigenetic, proteomic, imaging, wearable, and AI-based clocks. It finds that these tools can improve risk prediction beyond chronological age, but standardization, interpretability, and prospective validation are needed before routine clinical use.
