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.

Banning ultra-processed foods brings major hurdles for public schools

Starting in July 2029, public schools are required to start phasing out ultra-processed foods under a new California law that prohibits schools from serving foods high in sugar, fat, salt and certain artificial food additives.

New artificial intelligence model detects tissue damage in the heart

Researchers from the COR group at the Institute of Information and Communications Technologies (ITACA) of the Universitat Politècnica de València (UPV) have developed an artificial intelligence model capable of localizing and quantifying tissue abnormalities associated with atrial cardiomyopathy using electrical recordings from the body's surface.

Study reveals why consumers mistake short shelf life for naturalness of food

For years nutrition experts have warned about the many risks of eating ultra-processed foods: among them obesity, cardiovascular disease and diabetes. Instead, they advise that consumers opt for more natural offerings.

New framework maps the complex link between psychological status and cardiovascular health

CVD remains the leading cause of death worldwide, while the global burden of mental disorders continues to rise.

Research makes strong case for broader use of GLP1 drugs to protect hearts

New research being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) makes a case for extending the indication for GLP1- receptor agonists (GLP1-RAs) to millions more people, to protect their heart health.

Continuous glucose monitors show strong survival benefits for type 2 diabetes patients

People with type 2 diabetes (T2D) on basal insulin, starting continuous glucose monitoring (CGM) had a 44% lower risk of dying from any cause after one year compared with those who did not use CGM, with the risk being 35% lower after two years, according to an analysis of patient data being presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2).

A survey of 371,000 adults links heart disease to eating whole fruit less often

In a survey analysis of 371,038 US adults, those reporting high blood pressure, high cholesterol, a heart attack, or coronary heart disease ate whole fruit slightly less often than those without the respective conditions. After adjustment, 100% fruit-juice consumption was less frequent among adults with high cholesterol and more frequent among those reporting a heart attack, but the cross-sectional study cannot establish cause and effect.

Exam stress significantly raises blood sugar levels in medical students

Exam stress is associated with significant increases in blood sugar levels in medical students both during exams and the days leading up to them, according to new research being presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2).

Semaglutide cuts major heart events, but researchers still cannot fully explain why

In adults with overweight or obesity and established cardiovascular disease but no diabetes, semaglutide reduced major adverse cardiovascular events by 20%, while changes in measured cardiovascular risk factors could not fully explain the benefit with certainty. The findings suggest that additional, as-yet unidentified biological pathways may contribute to semaglutide’s cardiovascular protection.

New study tracks rising heart and kidney risks in people with type 2 diabetes

The risk of developing chronic kidney disease (CKD) or heart failure (HF), or dying, following a type 2 diabetes (T2D) diagnosis increases substantially over time, according to new research being presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2).

Cutting ultra-processed foods and exercising slashes diabetes risk

Eating a diet low in ultra-processed foods (UPFs) and exercising can cut the risk of type 2 diabetes, even in those with a strong genetic disposition to the condition, new research being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) suggests.

Why one gut microbe is attracting attention in heart failure research

Researchers found that chronic systolic heart failure caused by nonischemic cardiomyopathy was associated with reduced gut microbial diversity, depletion of Bifidobacterium, and lower microbial short-chain fatty acid production potential. Higher Bifidobacterium abundance and higher circulating indole-3-propionic acid levels were associated with milder disease and clinical improvement, although the findings do not establish causality.

Heated tobacco users had more hypertension, but the story is not that simple

A large Japanese real-world cohort study found that current heated tobacco product users had a higher risk of developing hypertension than never-smokers in the primary adjusted analysis. However, the association weakened in several sensitivity analyses, and the observational study could not separate the effects of current heated tobacco use from previous cigarette exposure.

Drone-delivered AEDs could reduce defibrillation delays after cardiac arrest

Drones could be used to deliver automated external defibrillators (AEDs) to where a person is suffering an out-of-hospital cardiac arrest, according to a study presented at the European Emergency Medicine Congress today (Saturday).

New pre-hospital blood test reduces unnecessary emergency department visits for chest pain

Researchers in The Netherlands have found that about 30% of presentations to emergency departments of patients with chest pain could be avoided if a highly sensitive troponin test is used in combination with other parameters by ambulance crews during pre-hospital triaging.

The heart effects of antidepressants may depend as much on the patient as the drug

Antidepressants differed in their effects on QTc, with amitriptyline and escitalopram producing small average increases, and the magnitude of changes varying according to individual patient characteristics. The trials did not detect an increase in early major cardiovascular events or non-suicidal sudden death, but they were not large or long enough to rule out rare or later cardiovascular events.

Study identifies shared pathway driving cardiac fibrosis

Three adenosine receptor subtypes that normally send different signals were found to converge on a common pathway that activates cardiac fibroblasts, the scar-forming cells in the heart.

Kidney rhythm mismatch linked to dangerous nighttime high blood pressure

Most people's blood pressure falls by 10 to 20 per cent while they sleep, giving the heart and blood vessels a chance to recover. But for some people, that nighttime dip never happens.

As GLP-1 drugs become more complex, their effects on the heart are getting harder to predict

A brief report reviews emerging GLP-1 receptor co-agonists that also target GIPR, GCGR, and other receptors, examining their metabolic benefits alongside known and predicted cardiac effects. The authors highlight substantial species differences, warning that mouse heart studies may fail to predict responses in human cardiac tissue and that many proposed cardiac effects still require direct testing.
