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.

Protecting the thymus may improve lung cancer treatment outcomes

Building on recent discoveries about the adult thymus, Mass General Brigham investigators used artificial intelligence to show that incidental radiation exposure to the thymus may influence outcomes in patients with lung cancer.

A year after women lost weight, researchers saw which health gains lasted and which faded

Diet-induced weight loss significantly reduced predicted 10-year risks of major adverse cardiovascular events and type 2 diabetes in healthy premenopausal women with overweight, regardless of whether aerobic or resistance exercise was added. Some of these gains diminished as weight was partially regained over the following year, although greater exercise adherence was associated with less rebound in predicted diabetes risk.

Researchers traced lifelong obesity resistance in mice back to an early microbial encounter

Natural wild-derived microbiota protected mice against diet-induced obesity across sexes, genetic backgrounds, and age by increasing energy expenditure and promoting a thermogenic program in brown adipose tissue. The effect depended on the immune system’s initial encounter with the microbiota and required CCR2-associated myeloid activity, revealing a long-lasting microbiota-immune-brown fat pathway.

Diabetes study reveals differing health risks for men and women

In the years following type 2 diabetes diagnosis, women are more likely to develop mental health conditions, while men are more likely to develop cardiovascular and renal complications, according to a study published August 25th in the open access journal PLOS Medicine by Fabiola Eto from Queen Mary University of London, UK, and colleagues.

Physical activity declines significantly with age despite good initial health

A recent study from the University of Jyväskylä, Finland, shows that physical activity declines substantially with age, even among older adults who are in good physical condition.

What decades of wine research can, and cannot, tell us about health

A narrative review found that moderate wine intake has repeatedly been associated with lower all-cause and cardiovascular mortality, with proposed mechanisms involving ethanol and grape-derived polyphenols, but the evidence remains largely observational and cannot establish causation. The authors argue that drinking pattern, beverage type, age, cancer risk, and risk-modeling choices all influence how the J-shaped association should be interpreted and how alcohol guidelines are developed.

From caffeine to trigonelline, coffee has surprising links to muscle biology

A scoping review of 54 studies found that coffee and several coffee-derived bioactive compounds influence pathways linked to skeletal muscle metabolism, including insulin signaling, mitochondrial function, oxidative stress, inflammation, glucose uptake, and protein turnover. Human studies reported associations with greater muscle mass and lower frailty or functional impairment, but most evidence remains observational or preclinical and cannot establish causality.

Could a daily vinegar drink help with constipation? A small trial offers a clue

A randomized, double-blind trial found that adults with mild constipation who drank a vinegar beverage daily for four weeks had more frequent bowel movements than those receiving placebo. Exploratory findings also suggested earlier improvements in bowel habits, although the small feasibility-based trial requires confirmation in larger and more diverse populations.

New study makes progress in understanding the mechanisms behind severity of HFpEF

Approximately 3 million people in the United States are living with a condition called heart failure with preserved ejection fraction, or HFpEF.

Type 2 diabetes mechanisms differ significantly based on patient BMI

Research published today in Diabetologia by Amsterdam UMC and the University of Ghana reveals that type 2 diabetes manifests in two fundamentally different ways depending on a patient's body mass index (BMI).

Semaglutide’s heart benefits may partly involve reduced inflammation

A prespecified analysis of 17,604 SELECT participants found that higher baseline hsCRP was associated with greater risks of major cardiovascular events and death in people with overweight or obesity and established cardiovascular disease. Semaglutide produced rapid and sustained reductions in hsCRP, with changes emerging before substantial weight loss, although the study could not establish whether reduced inflammation directly mediated its cardiovascular benefits.

These simple fitness tests revealed which older adults had the lowest death risk

Objective fitness tests in 13,423 Taiwanese adults aged 65 years or older linked better balance, agility, lower-body strength, and cardiorespiratory fitness with lower all-cause mortality over a median seven years. A multidomain fitness index showed the strongest association, suggesting that simple performance tests may add useful information to conventional geriatric risk assessment.

A two-year diet trial challenges the idea that weight loss is the only result that matters

In the two-year DELISH randomized trial, adults with obesity achieved modest, sustained weight loss with either an adapted Mediterranean-style program or a commercial weight loss program. The Mediterranean-style intervention produced greater improvements in self-reported diet quality, while 24-month weight loss did not materially differ between groups.

A striking immune cell pattern emerges around a person’s 100th birthday

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

Study highlights strengths and barriers of remote heart failure care

Interviews with patients hospitalized for heart failure, caregivers, providers, and organizational leaders highlighted several strengths of Mighty Heart (a major clinical trial examining the effectiveness of in home and telehealth-enabled visits from paramedics) that may support its adoption and implementation across health systems, a Columbia Nursing-led study finds.

Machine learning model can identify likely non-responders to exercise-based cardiac rehabilitation

Exercise training is a cornerstone of cardiac rehabilitation (CR) for patients with coronary artery disease (CAD), and current guidelines rate it as a top-tier recommendation for reducing the risk of future cardiovascular events.

Digital program reduces anxiety and depression in adults with chronic medical conditions

A digital program combining guided movement, breathing and meditation exercises, and coping-skills training reduced anxiety and depression symptoms in adults with chronic medical conditions, according to a new study published August 20th in the open access journal PLOS Medicine by Puneeta Tandon of the University of Alberta, Canada, and colleagues.

What happens to your diet when you get better at cooking?

Cooking-skills interventions were associated with healthier dietary behaviors in healthy adults, including greater fruit and vegetable intake, improved diet quality, and greater cooking confidence. However, the certainty of evidence was low to very low, and too little evidence was available to determine whether cooking skills affect nutritional status.

Study: Nearly 8 out of 10 young adults have cardiovascular-kidney-metabolic syndrome

A new scientific study found that nearly 8 out of 10 young adult participants, average age 23 years, had cardiovascular-kidney-metabolic syndrome (CKM syndrome), according to new independent research published today in Circulation: Population Health and Outcomes, a peer-reviewed scientific journal of the American Heart Association.
