Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
The endothelial cells that line blood vessels are packed tightly to keep blood inside and flowing, but scientists at Rice University and their colleagues have discovered it may be possible to selectively open gaps in those barriers just enough to let large molecules through -- and then close them again.
Results of an international, randomized controlled research study show that mechanical thrombectomy, which is an endovascular treatment to remove a stroke-causing blood clot in the brain, is effective in some patients even when performed within 6 to 24 hours after a stroke.
Running multiple marathons does not increase the risk of atherosclerosis, according to research published today in the European Journal of Preventive Cardiology.
The University of Illinois at Chicago College of Medicine will launch a new center that will focus on understanding tissue regeneration and pioneering future developments in stem cell biology as a means to repair diseased organs and tissues.
Cardiac surgeons are successfully performing more extensive surgical repairs of type A aortic dissection — one of the highest risk operations in cardiothoracic surgery.
The U.S. Food and Drug Administration today approved an expanded indication for the Sapien 3 Transcatheter Heart Valve (THV) for patients with symptomatic heart disease due to failure of a previously placed bioprosthetic aortic or mitral valve whose risk of death or severe complications from repeat surgery is high or greater.
One additional injection of insulin three hours after eating has been shown to protect people with type 1 diabetes from cardiovascular disease - the leading cause of death among people with the condition.
A stroke is a "brain attack" and occurs when blood supply to the brain is cut off. According to Kenneth A. Levin, M.D., Medical Director, The Valley Hospital Stroke Center, "Most strokes are caused by a blood clot that has built up on the wall of a brain artery or one that has traveled there from another part of the body (an embolic stroke or ischemic stroke).
It may be possible to disrupt harmful blood clots in people at risk for heart attack or stroke without increasing their risk of bleeding, according to a new study published in Nature Communications.
Brain changes after stroke may lead to increase in alcohol-seeking behavior, at least in animal models, according to research published Wednesday in the journal Scientific Reports.
Cluster headaches are probably the most painful types of pain a human can suffer and it is for no small reason that this condition is also sometimes referred to as suicide headache.
Hospitals vary widely in how often they transition people with strokes from active treatment to comfort or hospice care within 48 hours after they get to the hospital, according to a new study published in the May 24, 2017, online issue of Neurology Clinical Practice, an official journal of the American Academy of Neurology.
A new study led by researchers at Beth Israel Deaconess Medical Center, in collaboration with researchers at the Harvard T.H. Chan School of Public Health and the Aalborg University and Institute of Cancer Epidemiology in Denmark, found that consuming moderate amounts of chocolate was associated with significantly lower risk of being diagnosed with atrial fibrillation, a common and potentially life threatening type of irregular heartbeat.
In a new study, CT-measured vascular pruning – the diminution of distal pulmonary blood vessels (vessels on the outer edges of the lungs) – was associated with increased risk of death in smokers without chronic obstructive pulmonary disease.
In diseases like cancer, diabetes, rheumatism and stroke, a disorder develops in the blood vessels that exacerbates the condition and obstructs treatment.
Coronary artery disease (CAD) is a leading cause of death worldwide. Despite dozens of regions in the genome associated with CAD, most of the genetic components of heart diseases are not fully understood, suggesting that more genes are out there to be found.
Tests of cells collected from the umbilical cord blood vessel walls at birth can predict death or poor pulmonary outcomes in extremely preterm infants, say researchers at the University of Alabama at Birmingham.
Adding the injectable drug mepolizumab to standard treatment for eosinophilic granulomatosis with polyangiitis (EGPA), a rare immunologic disease, significantly improved clinical outcomes among participants in an advanced clinical trial, scientists report.
Results from the DAWN stroke trial presented at the European Stroke Organization Conference provide compelling evidence that selected patients suffering a major ischemic stroke recovered significantly better with mechanical retrieval of the blood clot with medical therapy compared with medical therapy alone when initiated past the current guidelines of within 6 hours and up to 24 hours of the stroke.
Royal Philips will showcase its market-leading image guided therapy solutions at EuroPCR 2017 (Paris, May 16 – 19, 2017) to advance interventional cardiology and make care more personalized, while optimizing patient care and hospital budgets. This year, the healthcare industry is celebrating the 40th anniversary of angioplasty, the minimally invasive treatment of obstructed blood vessels, and as a leader in interventional cardiology, Philips is reinforcing its longstanding commitment to transforming cardiac care with meaningful innovations.
