Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.

FDA-approved devices used to treat cardiovascular diseases

Heart disease, also called cardiovascular disease, can have serious consequences. It's the leading cause of death for adults in the U.S. Medical devices approved by the U.S. Food and Drug Administration, such as pacemakers and defibrillators, have extended and improved the lives of millions of people living with heart disease.

Nerinetide shows promise in stroke treatment meta-analysis

The Calgary Stroke Program, a joint University of Calgary and Alberta Health Services initiative at Foothills Medical Centre, has been involved with three papers published this week in The Lancet and Lancet Neurology-the ESCAPE-NEXT trial, the FRONTIER trial, and an individual patient-level meta-analysis across three trials.

Intracranial hemorrhages linked to higher dementia risk

Weill Cornell Medicine researchers have found that intracranial hemorrhages, or "brain bleeds" caused by a ruptured blood vessel in the brain, double a person's risk of developing dementia later in life.

Vascular changes in brain trauma could trigger Alzheimer’s development

An increased risk of dementia among individuals exposed to brain trauma, traumatic brain injury, has been known for almost a century.

Lung signals trigger blood clot formation in cancer patients

Blood clots form in response to signals from the lungs of cancer patients—not from other organ sites, as previously thought—according to a preclinical study by Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center and University of California San Diego Health. Clots are the second-leading cause of death among cancer patients with advanced disease or aggressive tumors.

Tenecteplase injection after clot removal improves stroke recovery

Removing a blood clot from a large brain artery, then injecting the clot-dissolving drug tenecteplase into the artery resulted in stroke survivors being more likely to have better function 90 days after their stroke than those receiving standard clot removal, according to preliminary late-breaking science presented today at the American Stroke Association's International Stroke Conference 2025.

ESCAPE-MeVO trial advances understanding of stroke treatment for medium-sized vessel blockages

University of Calgary's Hotchkiss Brain Institute researchers with the Calgary Stroke Program at Foothills Medical Centre revolutionized treatment for stroke with the ESCAPE Trial, proving that a clot retrieval procedure known as endovascular thrombectomy (EVT) can dramatically improve patient outcomes after an acute ischemic stroke caused by a blockage in a large-sized blood vessel.

Adrenomedullin hormone contributes to insulin resistance in obesity-associated type 2 diabetes

The hormone adrenomedullin disrupts insulin signaling in blood vessel cells, contributing to systemic insulin resistance in obesity-associated type 2 diabetes, according to a new study.

Late menopause linked to better vascular health in women

Women who go through menopause later in life have healthier blood vessels for years to come than those who go through it earlier, according to new University of Colorado Boulder research.

Rapid blood test could identify brain bleeds from clot-caused strokes

A blood test may rapidly distinguish brain bleeds from clot-caused strokes, even before people with stroke symptoms reach the emergency room, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2025.

AI-based blood test could revolutionize diagnosis of Long Covid in children

One day Long Covid in children could be objectively diagnosed with a blood test, thanks to the help of Artificial Intelligence (AI). In fact, a study by the Università Cattolica del Sacro Cuore, Rome campus - Fondazione Policlinico Universitario Agostino Gemelli IRCCS and the Ospedale Pediatrico Bambino Gesù IRCCS, has highlighted the molecular signature of Long Covid in plasma in pediatric age and used an AI tool capable of making the diagnosis based on the results of the blood sample, with 93% accuracy.

Over-dilation of microvasculature may contribute to chronic limb-threatening ischemia

Persistent over-dilation of muscle microvasculature may be one reason causing chronic limb-threatening ischemia, recent studies by Kuopio University Hospital and the University of Eastern Finland show.

Researchers identify a natural defense against blood vessel inflammation and atherosclerosis

Research reveals IGFBP6's role in suppressing vascular inflammation and atherosclerosis, suggesting it as a novel target for cardiovascular disease therapy.

Study links epigenetic mechanism to placental blood vessel development

If the development of blood vessels in the placenta is impaired, fetal growth retardation may result. Scientists from the German Cancer Research Center (DKFZ) and the Mannheim Medical Faculty of Heidelberg University discovered that the correct development of functioning blood vessels in the mouse placenta is controlled epigenetically: One of the enzymes that modify gene activity using methyl groups is responsible.

Researchers uncover role of perivascular cells in blood vessel dysfunction

Researchers at Oregon Health & Science University have uncovered how specialized cells surrounding small blood vessels, known as perivascular cells, contribute to blood vessel dysfunction in chronic diseases such as cancer, diabetes and fibrosis.

Blood vessel dysfunction in brain's temporal lobes linked to mild cognitive impairment

Mild cognitive impairment is linked to blood vessel dysfunction in the brain's temporal lobes - the seat of memory - according to a new USC-led study.

Study reveals route of entry for Semliki Forest virus into the brain

In a recent study, researchers from Uppsala University show that the Semliki Forest virus enters the central nervous system by first entering the cerebrospinal fluid and then binding to a specific cell type before penetrating deeper into the brain.

Aircraft noise pollution harms arteries, but heart drugs show promise in animal model research

Alpha- and beta-blockers reduce oxidative stress and inflammation caused by aircraft noise but fail to prevent hypertension, highlighting their potential to protect vascular health in noise-exposed individuals.

High blood pressure may not harm brains of 90-year-olds, study finds

A study led by the University of California, Irvine has found cardiovascular conditions such as high blood pressure and diabetes, which are known to contribute to brain blood vessel damage in younger populations, not to be associated with an increased risk of such harm in individuals 90 and older.
