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.

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.

25 Sep 2026

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.

24 Sep 2026

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.

Human crying catches dogs’ attention across homes, shelters, and streets

A study of 112 pet, shelter, and free-ranging dogs found that all three groups looked more toward people simulating crying than humming.

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.

Study finds oral hormone replacement therapy increases venous thromboembolism risk

Current use of oral menopausal hormone therapy (commonly known as hormone replacement therapy or HRT) is associated with an increased risk of blood clots in legs / lungs regardless of dose or treatment duration, finds a large Danish study published by The BMJ today.

Semaglutide’s heart benefits may extend beyond weight loss

Semaglutide is known to reduce the risk of serious heart disease. However, a new study published in the European Heart Journal today (Thursday) suggests that this effect cannot not be entirely explained by patients losing weight on the drug.

Nearly 60% of hypertension cases remain undetected in England

Researchers from Oxford Population Health analyzed clinic blood pressure measurements collected by Our Future Health, the UK's largest health research programme, from participants who enrolled between 2022 and 2025.

Frailty linked to greater cognitive impairment risk in men with chronic kidney disease

New research from the University of Colorado Anschutz Department of Medicine is shedding light on how women and men with chronic kidney disease (CKD) may fare differently as they age and their disease progresses.

Stroke rates nearly doubled among younger adults over three decades

Stroke is becoming more common among younger adults, according to a study published September 23, 2026, in Neurology, the medical journal of the American Academy of Neurology.

WSU study reveals acute effects of cannabis on physiological stress-related outcomes

Cannabis is often used as a stress reliever, but a new study suggests that some of the body's stress response systems don't get the message.

Parental plastic exposure harms offspring through multiple biological routes

Microplastics and nanoplastics are increasingly found throughout aquatic environments, raising concern about whether these tiny particles can move from exposed parents into their offspring.

What links smoking, body fat, mental health, genes, and heart risk? Inflammation may be part of the answer

In a large UK Biobank study, higher levels of the chronic inflammation marker GlycA were associated with smaller heart chambers, thicker heart walls, impaired diastolic function, reduced stroke volume, and a 43% higher risk of major adverse cardiovascular events in the highest versus lowest GlycA group. Genetic susceptibility also modified the associations between environmental exposures, inflammation, and cardiovascular risk, while inflammatory proteins in the IL-1, TNF, and IL-6 pathways statistically mediated several of these associations.

Higher ultra-processed food intake linked to multiple health risks

A higher ultra processed food (UPF) intake is linked to a heightened risk of several major chronic health issues, such as digestive diseases, high blood pressure, and metabolic syndrome/diabetes, as well as death, finds a pooled data analysis of the available evidence, published in the open access journal Family Medicine and Community Health.

Loneliness and social isolation cost people years of healthy life

The numbers paint a grim picture. Roughly half of all U.S. adults are lonely, according to a 2023 report, and nearly as many feel socially isolated.

Childhood trauma linked to risky health behaviors in late adolescence

Experiencing childhood trauma appears to increase a young person's likelihood of smoking, substance use and developing unhealthy eating habits by contributing to behavioral problems during adolescence, such as impulsivity and poor self-control.
