Chronic cannabis use linked to significant cardiovascular risks

A new study led by UC San Francisco researchers finds that chronic cannabis use - whether it's smoked or consumed in edible form - is associated with significant cardiovascular risks.

New injection therapy can lead to long lasting blood pressure reduction

Results from a clinical trial led by researchers from Queen Mary University of London, published today in JAMA, show that giving people with high blood pressure an injection every six months can lead to a meaningful, sustained reduction in their blood pressure.

Intestinal bacteria and their metabolites contribute directly to vascular aging

The aging of the innermost cell layer of blood vessels leads to cardiovascular diseases. Researchers at UZH have now shown for the first time that intestinal bacteria and their metabolites contribute directly to vascular aging.

New biomarker identified for predicting microvascular health of the kidneys

In a world first, Canadian scientists at the CRCHUM, the hospital research centre affiliated with Université de Montréal, have identified microRNA able to protect small blood vessels and support kidney function after severe injury.

Study sheds light on how tumor clusters enter the bloodstream

Tumors are made up of millions of cells, and removing all of these cells surgically or eliminating them with medication becomes much more difficult after the cancer has spread to other parts of the body.

Reduced monitoring after stroke found safe for low risk patients

Halving the number of times vital signs and neurological function are checked in low-risk patients after treatment for acute ischaemic stroke does not compromise care or recovery, according to new findings presented at the 11th European Stroke Organisation Conference in Helsinki, Finland.

Air pollution fuels artery damage and accelerates heart disease, review finds

Researchers reviewed how air pollution, especially fine particulate matter (PM2.5), drives the development and worsening of atherosclerosis, a leading cause of heart attacks and strokes. Their findings highlight robust links between air pollution exposure, early artery changes, and underlying biological mechanisms fueling cardiovascular risk.

Breakthrough microimager offers new possibilities for internal imaging

Researchers have developed an extremely thin, flexible imager that could be useful for noninvasively acquiring images from inside the body. The new technology could one day enable early and precise disease detection, providing critical insights to guide timely and effective treatment.

Red blood cells drive blood vessel damage in diabetes by exporting toxic vesicles

Red blood cell-derived extracellular vesicles in type 2 diabetes are actively taken up by the endothelium, transferring the enzyme arginase-1 and triggering oxidative stress. This mechanism helps explain vascular complications in diabetes and offers new targets for therapeutic intervention.

Evolution of malaria protein family offers new drug targets

Researchers from the Francis Crick Institute and the Gulbenkian Institute for Molecular Medicine (GIMM) have shown that the evolution of a family of exported proteins in the malaria-causing parasite Plasmodium falciparum enabled it to infect humans.

Flavan-3-ols in tea and chocolate can lower blood pressure

We might have another reason to enjoy our daily cup of tea or small piece of dark chocolate, as a new study from the University of Surrey has found that naturally occurring compounds called flavan-3-ols - found in cocoa, tea, apples and grapes - may improve blood pressure and the health of our blood vessels.
