Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
Virtually no other disease has seen such massive strides in treatment in recent years as stroke. Recent studies have confirmed that it is still possible to mechanically remove large vessel occlusions in the brain many hours after a stroke occurs.
When performed in tandem, two molecular biology laboratory tests distinguish, with near certainty, pancreatic lesions that mimic early signs of cancer but are completely benign.
In people with high cholesterol levels, the fat that is built up in the artery walls narrows the arteries causing a condition called atherosclerosis. A study published on 19th June in the European Heart Journal has found the likelihood of a vaccine that can immunize humans having atherosclerosis, subsequent to successful outcomes in a mouse model study. At present, phase I clinical trial has begun in patients to see the possibility of translating the study findings to humans.
While it's widely held that tumors can produce blood vessels to support their growth, scientists now have evidence that cells key to blood vessel formation can also produce tumors and enable their spread.
Patients with severe and end-stage heart failure have few treatment options available to them apart from transplants and "miraculous" stem cell therapy.
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.
