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.

TOAST classification remains effective, easy-to-use system to classify strokes

In 1993, neurologists Harold P. Adams Jr., MD, and Jose Biller, MD, and colleagues proposed a new way to classify strokes. It became known as the TOAST classification. Twenty-two years later, the TOAST classification remains an effective and easy-to-use system that is routinely employed in stroke studies around the world, Drs. Adams and Biller report in the journal Stroke, published online ahead of print.

Pouchlike structure inside the heart's left atrial chamber could cause strokes

A pouchlike structure inside the heart's left atrial chamber in some people may explain strokes that otherwise lack an identifiable cause, according to UC Irvine School of Medicine researchers.

New stent retriever device reduces stroke damage

Elizabeth Celli was experiencing a moderate-to-severe stroke when she arrived at Loyola University Medical Center's Emergency Department. Mrs. Celli was weak on her left side, had difficulty speaking and was unable to walk. But after being treated with a new device called a stent retriever, her symptoms dramatically reversed.

Laparoscopic hysterectomy with morcellation safer than abdominal procedure for treating presumed fibroid uterus

In a new study published in the American Journal of Obstetrics & Gynecology, researchers from The University of North Carolina at Chapel Hill compared the relative risks of laparoscopic hysterectomy (with morcellation) with abdominal surgery for hysterectomy in premenopausal women undergoing surgery for presumed uterine fibroids.

UM experts warn of serious risks associated with common IV devices

Every day, patients around the country get IV devices placed in their arms, to make it easier to receive medicines or have blood drawn over the course of days or weeks. But these PICC lines, as they're called, also raise the risk of potentially dangerous blood clots.

Anticoagulant drug bivalirudin shows mixed results in MATRIX trial

Patients with acute coronary syndrome undergoing angioplasty who received the anticoagulant drug bivalirudin did not show significant improvements in either of two co-primary endpoints--a composite of rate of death, heart attack or stroke at 30 days, or a composite of those events plus major bleeding--as compared to patients receiving standard anticoagulation therapy, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session.

New anti-clotting therapy no better than established anticoagulants

A novel therapy that would allow doctors to turn the body's blood-clotting ability off and on in a more controlled way was about as effective as established anticoagulants in patients undergoing angioplasty but was associated with higher rates of moderate to severe bleeding, according to an analysis of data from a terminated Phase III trial presented at the American College of Cardiology's 64th Annual Scientific Session.

3D printed heart models to aid doctors plan for complex ops'

A team of doctors at Cincinnati Children’s Hospital Medical Center are exploring new avenues to improve surgical preparations and patient care. The hospital recently partnered with the University of Cincinnati’s College of Engineering and Applied Science (CEAS) to produce a 3D printed heart model of a patient with a rare, life-threatening heart condition. 3D printed anatomical models derived from patient scans enable doctors to “practice” surgery in advance and assess possible complications for delicate procedures, improving the outcome of operations.

Simultaneous use of hormones and statins can protect women from heart disease after menopause

Hormones may not protect women from heart disease or stroke after menopause, but when combined with cholesterol-lowering statin drugs, they may help protect women from these killers, shows a population study from Sweden to be published in the April issue of Menopause, the journal of The North American Menopause Society.

New drug fails to prevent irreversible injury to the heart after angioplasty

Patients who received the new drug Bendavia before undergoing angioplasty or receiving a stent to clear blocked arteries after a heart attack showed no significant reduction in scarring as compared to patients given a placebo, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session.

18 Mar 2015

Routine use of thrombectomy in heart attack patients may increase risk of stroke

The largest study ever of its kind, led by researchers from McMaster University and the University of Toronto, has found that a routine strategy of blood clot removal during treatment for heart attacks was not beneficial and was associated with an increased risk of stroke.

Patients with multiple narrowed arteries have better outcomes with CABG than with PCI

Despite the advent of a new generation of stents, patients with multiple narrowed arteries in the heart who received coronary artery bypass grafting fared better than those whose arteries were opened with balloon angioplasty and stents in a study presented at the American College of Cardiology's 64th Annual Scientific Session.

Study compares latest drug-coated stents with traditional bypass surgery

Newer drug-coated stents that keep arteries open have similar long-term rates of death compared with traditional bypass surgery for patients with more than one diseased coronary artery.

New injectable polymer could strengthen blood clots

Most military battlefield casualties die before ever reaching a surgical hospital. Of those soldiers who might potentially survive, most die from uncontrolled bleeding.

Scientists develop mathematical model to digitally map communication between heart cells

A team of scientists led by Johns Hopkins cardiologist and biomedical engineer Hiroshi Ashikaga, M.D., Ph.D., has developed a mathematical model to measure and digitally map the beat-sustaining electrical flow between heart cells.

Hormone therapy does not safeguard post-menopausal women against cardiovascular disease

New evidence published today in the Cochrane Library shows that hormone replacement therapy does not protect post-menopausal women against cardiovascular disease, and may even cause an increased risk of stroke.

New ASH report outlines several models for 'systems-based clinical hematologist'

A report released today from the American Society of Hematology in its journal, Blood, presents an innovative, sustainable new role for hematologists, particularly those specializing in non-malignant blood diseases, for today’s rapidly changing U.S. health-care system.
