Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

Scientists discover how fat tissue drives the spread of triple-negative breast cancer

Triple-negative breast cancer (TNBC) is aggressive and hard to treat. But the role of fat tissue in how the cancer spreads may help point toward new understanding and treatments, according to a new paper from scientists at the Hackensack Meridian Center for Discovery and Innovation (CDI) and colleagues at Georgetown University's Lombardi Comprehensive Cancer Center.

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.

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.

Elite athletes with higher vitamin D show healthier lipid profiles

Higher serum 25-hydroxyvitamin D levels were independently associated with lower LDL-C, triglycerides, and lipoprotein(a) in 773 male professional athletes. The cross-sectional study cannot establish causality, but it suggests that vitamin D status may be linked to cardiovascular risk-related lipid markers, even in elite athletic populations.

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.

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.

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.

PMOS rethink reframes a common hormone disorder as a whole-body disease

A new review reframes PCOS, now proposed as PMOS, as a systemic endocrine and metabolic disorder shaped by genetic, epigenetic, ovarian, metabolic, and neuroendocrine pathways. It highlights why inconsistent diagnosis and symptom-focused care have limited progress, while targeted therapies, biomarkers, machine learning, and organ-on-chip models may support more personalized treatment.

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.
