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.

Study: Short-term exposure to major air pollutants may increase risk of MI

Short-term exposure (for up to 7 days) to all major air pollutants, with the exception of ozone, is significantly associated with an increased risk of heart attack, according to a review and meta-analysis of previous studies appearing in the February 15 issue of JAMA.

Kowa announces data of LIVALO vs. Crestor on pharmacodynamics of warfarin

Kowa Pharmaceuticals America, Inc. today announced data assessing the effect of LIVALO (pitavastatin) compared with Crestor (rosuvastatin) on steady-state pharmacodynamics (PD) of warfarin by measuring international normalized ratio (INR) in healthy adult subjects.

Elevated risk of PE occurs within first 7 days after total joint replacement surgery

The elevated risk of pulmonary embolism (PE) - a blood clot that travels from the leg to the lungs - following total joint replacement (TJR) surgery has been well established, yet little is known about the natural course and timing of this potentially fatal condition.

Anticoagulation drugs can prevent PE, DVT after total joint replacement

Following a total joint replacement, anticoagulation (blood thinning) drugs can prevent Deep Vein Thrombosis (DVT), a blood clot deep within the extremities, or a pulmonary embolism (PE), a complication that causes a blood clot to move to the lungs.

New guidelines for travellers to avoid DVT on long flights

New guidelines for travellers have been issued. Experts warn that those with a higher risk of serious blood clots who opt for the window seat on flights longer than four hours are potentially putting themselves in danger. People who should be most concerned are those who have recently had surgery, cancer patients, those with limited mobility, the severely obese, and travellers over 70. However, healthy women on the pill and those who are pregnant should also be careful, according to the guidelines by the American College of Chest Physicians.

New blood-thinning drugs likely to replace Coumadin for patients with non-valvular AF

Within a few years, a new generation of easy-to-use blood-thinning drugs will likely replace Coumadin for patients with irregular heartbeats who are at risk for stroke, according to a journal article by Loyola University Medical Center physicians.

New ACCP guidelines address DVT/PE risk factors for long-distance travel

New evidence-based guidelines from the American College of Chest Physicians (ACCP) address the many risk factors for developing a deep vein thrombosis (DVT), or blood clot, as the result of long-distance travel.

New stent retriever procedure safe, effective for patients with stroke

A new way of opening blocked arteries in the brain using a removable stent system in people suffering strokes brought remarkably positive results in how those patients recovered from the strokes, according to a study presented this morning at the American Stroke Association's annual conference in New Orleans.

CT-guided catheters carry t-PA to shrink clots in patients with ICH

Johns Hopkins neurologists report success with a new means of getting rid of potentially lethal blood clots in the brain safely without cutting through easily damaged brain tissue or removing large pieces of skull. The minimally invasive treatment, they report, increased the number of patients with intracerebral hemorrhage (ICH) who could function independently by 10 to 15 percent six months following the procedure.

Aspirin plus clopidogrel unlikely to prevent recurrent strokes and may increase risk of death, bleeding

The anti-blood clot regimen that adds the drug clopidogrel (Plavix) to aspirin treatment is unlikely to prevent recurrent strokes and may increase the risk of bleeding and death in patients with subcortical stroke according to late-breaking research presented at the American Stroke Association's International Stroke Conference 2012.

Aspirin and warfarin similar in preventing deaths and strokes in heart failure patients

In the largest and longest head-to-head comparison of two anti-clotting medications, warfarin and aspirin were similar in preventing deaths and strokes in heart failure patients with normal heart rhythm, according to late-breaking research presented at the American Stroke Association's International Stroke Conference 2012.

New experimental device effectively removes blood clots in stroke patients

An experimental device for removing blood clots in stroke patients dramatically outperformed the standard mechanical treatment, according to research presented by UCLA Stroke Center director Dr. Jeffrey L. Saver at the American Stroke Association's 2012 international conference in New Orleans on Feb. 3.

Aggrenox not affected by co-administration of omeprazole: Study

Boehringer Ingelheim presented results of a drug interaction study that found Aggrenox (aspirin/extended-release dipyridamole), an antiplatelet medication, is not affected by the co-administration of omeprazole, a proton pump inhibitor (PPI), frequently used to treat several gastrointestinal conditions. These data were presented at the International Stroke Conference (ISC) in New Orleans.

New drug might effectively prevent clot-related strokes in patients with AF

For patients with a type of irregular heart beat called atrial fibrillation (AF), a new anti-clotting drug might be better at preventing clot-related strokes while minimizing the risk of causing a bleeding stroke.

Stryker announces results from clinical study of Trevo System on acute ischemic stroke

On February 2, at the Late-Breaking Science Session at the International Stroke Conference, Stryker announced the results of the TREVO Study (Thrombectomy REvascularization of large Vessel Occlusions in acute ischemic stroke). This was one of the first prospective, multi-center clinical studies of clot-removing stent retriever technology.

Postmenopausal women at higher risk of stroke than they think

A new study by researchers at NYU Langone Medical Center and colleagues found that traditional risk factors for stroke - such as high cholesterol - are not as accurate at predicting risk in postmenopausal women as previously thought. Instead, researchers say doctors should refocus their attention on triglyceride levels to determine which women are at highest risk of suffering a devastating and potentially fatal cardiovascular event.

Occasional erratic heart rhythms cause about one-fifth of unexplained strokes

Occasional erratic heart rhythms appear to cause about one-fifth of strokes for which a cause is not readily established, according to research presented at the American Stroke Association's International Stroke Conference 2012.

Strong link between triglyceride levels and ischemic stroke in older women

In a surprising finding with significant implications for older women, researchers at Albert Einstein College of Medicine of Yeshiva University and NYU School of Medicine have found that high levels of triglycerides (blood fats) are the strongest risk factor for the most common type of stroke in older women – more of a risk factor than elevated levels of total cholesterol or of low-density lipoprotein (LDL) cholesterol.

Clazosentan reduces risk of blood vessel spasm in patients with brain aneurysm

An experimental drug, clazosentan, reduced the risk of blood vessel spasm in patients with a brain aneurysm, according to research presented at the American Stroke Association's International Stroke Conference 2012.
