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

Cardiologists recommend reassessing need for additional stents later

A blocked coronary artery causing an acute heart attack must be opened immediately with a stent procedure. However, if other coronary arteries also appear to be narrowed, it is safe to wait and treat those later. This approach cuts the number of stent procedures in half, according to cardiologists from Radboud university medical center, writing in The New England Journal of Medicine.

AI repurposes routine CT scans to detect hidden bone loss

Computed tomography (CT) scans of the chest, abdomen, and spine, taken originally to detect problems such as kidney stones or growths on the lungs, can be repurposed through artificial intelligence (AI) to catch signs of bone loss, a new study shows.

New initiative boosts cholesterol control in veterans with heart and blood vessel disease

A quality improvement program helped reduce "bad cholesterol" (LDL or low-density lipoprotein) levels among military veterans who have heart and blood vessel disease, according to a preliminary late-breaking science presentation today at the American Heart Association's Scientific Sessions 2025.

Breakthrough study maps impact of thousands of variants in heart disease gene

An international research consortium co-led by scientists from Vanderbilt University Medical Center, the University of Toronto and University of Pittsburgh has mapped the functional impact of more than 17,000 variants in a major gene associated with the development of premature atherosclerotic heart disease.

Oligodendrocyte progenitor cells promote blood vessel growth after stroke

Stroke is a leading cause of death and disability, affecting 1 in 4 people during their lifetime. Stroke happens when blood vessels in the brain get clogged or damaged, impairing blood flow and oxygen supply to the brain, which leads to death of neurons and other brain cells.

Study links short-term blood pressure variability to Alzheimer's-related brain loss

Even when blood pressure is well controlled, older adults whose blood pressure fluctuates widely from one heartbeat to the next may be at greater risk for brain shrinkage and nerve cell injury, according to a new study led by the USC Leonard Davis School of Gerontology.
