Blood Clot News and Research

RSS

A Blood Clot is a mass of blood that forms when blood platelets, proteins, and cells stick together. When a blood clot is attached to the wall of a blood vessel, it is called a thrombus. When it moves through the bloodstream and blocks the flow of blood in another part of the body, it is called an embolus.

Unique arrays of proteins tethered onto self-assembled DNA nanostructures

In the fifty-year history since the structure of DNA was first revealed, what was once a Nobel prize- winning research discovery has become an omnipresent cultural icon co-opted for promoting everything from fragrances to musical acts.

Invasive treatment including stenting may be more effective for heart attack patients who arrive late at hospital

Invasive treatment including stenting may have better outcomes than conventional treatments for heart attack patients who arrive at the hospital more than 12 hours after symptoms began, according to a study in the June 15 issue of JAMA.

Experimental drug therapy could open new window for treatment of deadly stroke

A new type of drug therapy that is currently being tested in Canada could significantly reduce the death rate caused by the deadliest form of stroke. According to the Canadian Heart and Stroke Foundation, new developments in stroke research make it more important than ever that Canadians recognize and react to the warning signs of stroke.

High-tech imaging software locates more accurately the abnormal electrical impulses that produce heart arrhythmias

Loyola University Health System is one of the first hospitals in the United States to employ new high-tech imaging software - in conjunction with a three-dimensional cardiac mapping and navigation system - to locate more accurately the abnormal electrical impulses that produce heart rhythm disturbances (arrhythmias). This technology represents a major breakthrough in treating complex arrhythmias.

Genetic variation alters response to anti-clotting drug warfarin

Millions of people take the anticoagulant drug warfarin to prevent harmful clotting after a heart attack, stroke, or major surgery. But the proper dose of warfarin can vary greatly and can be hard to predict.

Hypertension, diabetes and obesity are important independent predictors of increased complications for patients undergoing major joint replacement surgery

Using a database of nearly 1 million Americans who underwent major joint replacement surgery, a team led by researchers at Duke University Medical Center have determined those surgical patients with diabetes, hypertension or obesity were significantly more likely to suffer post-operative complications.

Long-haul flights, length of time under anesthesia increase risk of developing blood clots

The prolonged immobility of flight passengers during long-haul air travel increases the risk of developing blood clots, which could prove fatal especially to people whose travel occurs just prior to major surgery, medical researchers report in the current issue of Mayo Clinic Proceedings.

Fluorescence device to diagnose atherosclerosis and tumors

In a presentation at the Conference on Lasers and Electro-Optics (CLEO), researchers from Cedars-Sinai Medical Center's Biophotonics Research and Technology Development Laboratory described recent progress on a device that stimulates, collects and measures light emissions from body tissues to diagnose critical atherosclerotic plaques (vulnerable plaques) and aggressive brain tumors.

Competition from specialty hospitals promotes high-quality patient care

Specialty hospitals provide quality care to patients by offering new choices, and this hospital competition should not be stifled, the American Medical Association (AMA) testified to a subcommittee of the Senate Committee on Homeland Security and Governmental Affairs this week.

Direct link between inefficient metabolism and atherosclerosis

An experiment that turned out very differently than expected led scientists at Washington University School of Medicine in St. Louis to the first direct link between inefficient metabolism and atherosclerosis.

Study shows how COX-2 inhibitors lead to heart disease

University of Pennsylvania School of Medicine researchers have found additional evidence that may help explain how selective inhibitors of COX-2 might predispose individuals to heart disease and stroke.

Obstructive sleep apnea significantly increases the risk of suffering a stroke

Moderate to severe cases of the nighttime breathing problem known as obstructive sleep apnea significantly increases the risk of suffering a stroke, according to a study to be presented at the American Thoracic Society International Conference on May 23.

Patients at high risk of stroke may need to continue Warfarin therapy after heart rhythm is controlled

Treatment with warfarin, a medication that prevents blood clotting, may reduce the risk of stroke by more than two-thirds in patients with atrial fibrillation (AF), a condition which places them at high risk of stroke, according to a study in the May 23 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Zevalin safe and effective for non-Hogdkin's lymphoma patients

According to a University of Pittsburgh Medical Center (UPMC) study, patients with advanced non-Hodgkin's lymphoma (NHL) previously treated with chemotherapy and adult stem cell transplantation can safely tolerate Zevalin (ibritumomab tiuxetan), a radiolabeled monoclonal antibody that targets radiation directly to a tumor.

Patients who have a blood clot are at high risk of having another one, and men have more than twice the risk as women

While estimates of the overall risk of a thrombotic (blood clot) event recurrence vary, reports on contributing factors are contradictory, according to background information in the article. Knowledge of the risk of a thrombotic event recurrence and its determinants is relevant for clinical policy regarding screening for thrombophilia (increased risk for blood clot), duration of anticoagulant treatment, and treatment strategies in circumstances of increased risk.

Tumor vasculature has become an attractive target in the treatment of cancer.

Treatment with a protein fused to an antibody in tumor-bearing mice led to coagulation of the blood within the tumor blood vessels, tumor tissue death, and tumor growth delay, according to a new study in the May 18 issue of the Journal of the National Cancer Institute.
