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.

Machine learning can identify older heart failure patients at risk of losing independence

For older adults with heart failure (HF), leaving the hospital alive does not always mean returning to an independent life. Loss of independence can reduce quality of life, increase caregiver burden, and raise care needs.

Caregivers with heart disease face high psychological distress risks

Family caregivers often put their own health second. For those already living with cardiovascular conditions, caregiving can add to their physical and emotional strain.

New AI model detects hidden diseases in routine CT scans

When analyzed by a new artificial intelligence model developed at Penn Medicine, CT scans reveal much about a patient's health beyond the specific condition they were originally ordered for, according to a new study published in NPJ Digital Medicine.

Premature menopause linked to higher heart disease risk and insulin levels

Premature menopause is associated with an increased risk of several long-term health problems due to estrogen deficiency.

Blood pressure drug losartan boosts metabolism by stimulating brown fat

Losartan, a drug commonly prescribed for high blood pressure, boosts brown adipose tissue or "brown fat" activity and enhances its metabolism, according to a preclinical study by Weill Cornell Medicine, Rockefeller University and Memorial Sloan Kettering Cancer Center researchers.

UCL study reveals broad mortality risks faced by ADHD individuals

For the study, published in JAMA Network Open, the researchers conducted a systematic review and meta-analysis of 19 studies that included data from close to 16 million study participants on three continents.

Miro1 protein linked to insulin resistance in type 2 diabetes

A protein called Miro1 found at elevated levels in the skeletal muscle of people with Type 2 diabetes may contribute to insulin resistance, potentially making it a target for future treatments that help the body regulate blood sugar, according to a study published today in Nature Communications.

GLP-1 medications linked to reduced postoperative infections and heart complications

GLP-1 medications, widely prescribed for diabetes and weight loss, may also help protect people from serious complications after surgery.

Cannabis users face increased heart attack risk around surgery

As marijuana use becomes more common and legal in most U.S. states, patients who use cannabis may face a significantly higher risk of heart attack around the time of surgery, while also showing an unexpected lower risk of dangerous blood clots in the veins, suggests a study presented at the ANESTHESIOLOGY® 2026 annual meeting.

Menopause isn't the end of the story for the ovaries

Research reveals that postmenopausal ovaries remain active, showing molecular remodeling linked to inflammation and potential implications for women's health.

What you did last week may be the strongest clue to how much you'll exercise this week

Researchers analyzing exercise records from 5.17 million Strava users across 65 countries found that recent exercise history was the strongest predictor of whether individuals would meet a weekly physical activity threshold during the COVID-19 pandemic. Physical activity patterns varied considerably across regions, with greater disruption in many middle-income countries and better adherence associated with greater access to outdoor exercise facilities.

You don't need 10,000 steps a day to benefit your heart, cardiologists say

A new American College of Cardiology scientific statement recommends integrating individualized exercise prescriptions into routine cardiovascular care, drawing on evidence supporting aerobic activity, resistance training, and cardiac rehabilitation. The authors emphasize that previously inactive individuals have the most to gain from increasing physical activity, while exercise recommendations should consider individual health conditions, functional capacity, and safety.

Your age may not tell the whole story about your health, but your blood could

Researchers analyzed plasma metabolites from 18,476 individuals aged 1 to 96 years and developed two metabolomic aging measures to assess biological aging, chronic disease, and mortality risk. Accelerated metabolomic aging was associated with greater risks of chronic disease and death, while a separate mortality-linked measure provided additional information about health status and disease burden beyond conventional clinical assessments.

Parents know fruit and vegetables are healthy, but many underestimate how much children need

A qualitative study involving 15 Swedish parents found that although most recognized the health benefits of fruit and vegetables, many underestimated recommended daily intake and considered serving vegetables at dinner sufficient. Researchers identified four overlapping parental roles influencing children's eating habits and suggested that clearer guidance on quantities, serving frequency, and practical feeding approaches could help families improve consumption.

AI study of 101,000 patients links brown fat to heart and mental health

In a retrospective analysis of PET-CT records from 101,243 patients, researchers found that detectable brown fat was associated with lower prevalence of cardiometabolic and psychiatric conditions, while greater activity, particularly in the axillary region, was linked to more favourable metabolic outcomes. Medication screening identified losartan, which increased brown fat thermogenic activity in laboratory experiments and energy expenditure in mice, although its effects on human brown fat remain unproven.

New scientific statement urges doctors to prescribe exercise for heart health

Exercise should be prescribed as a foundational component of cardiovascular disease (CVD) prevention and treatment, according to a new American College of Cardiology Scientific Statement published today in JACC, its flagship journal.
