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 reveals why many patients fail to recover after stroke

A clot forms. Blood flow to the brain is blocked. Starved of oxygen, neurons begin to die.

Catheter-directed thrombolysis improves short-term outcomes in pulmonary embolism patients

In patients with intermediate−high risk pulmonary embolism, catheter-directed thrombolysis improved short-term clinical outcomes compared with standard anticoagulation therapy alone, according to results presented in a Hot Line session today at ESC Congress 2026.

New findings do not support the use of edoxaban in AF patients after intracranial hemorrhage

Edoxaban did not reduce stroke or systemic embolism but increased major bleeding in high-risk patients with atrial fibrillation who had had an intracranial hemorrhage, according to results presented in a Hot Line session today at ESC Congress 2026.

New stroke guideline mandates personalized and early rehabilitation

A stroke can change life in an instant, affecting everything from walking and speaking to memory, mood and the ability to perform everyday tasks.

Multiple long-term conditions raise pregnancy risks, study finds

Women who begin pregnancy with two or more pre-existing, long-term physical or mental health conditions have 20% higher risk of miscarriage, 69% higher risk of severe nausea and vomiting, and around four times the risk of anxiety and depression, compared with those with no long-term conditions.

Stretchable catheter could help identify high-risk arterial plaque

We all know about plaque from dreaded trips to the dentist. But plaque can also build up inside the arteries, taking the form of fatty deposits that can potentially restrict blood flow.

Researchers develop artery-on-a-chip platform to predict stroke risk

Predicting an individual's risk of ischemic stroke is difficult because thrombosis embolization-the process of a blood clot detaching from the area where it formed and traveling to and then sticking in another blood vessel-is based on factors that are unique to each person.

Engineered blood clots form faster to stop severe bleeding

Blood clotting is one of the body's oldest survival mechanisms-a biological defense that has protected humans from dangerous bleeding for millions of years.

GLP-1 therapies linked to fewer complications in adults with both obesity and autoimmune disease

Among adults with both obesity and an autoimmune disease, those taking a glucagon-like peptide-receptor 1 agonist (GLP-1RA) medication had lower rates of emergency department visits and were less likely to experience serious cardiac events, such as stroke, pulmonary embolism or death when compared to similar adults who were not taking these medications, according to new research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

New PET radiotracer shows high accuracy for detecting clots in the legs and lungs

A novel PET radiotracer can accurately detect deep vein thrombosis in the legs and reveal whether clots have migrated to the lungs.

Study reveals how immune cells alter vascular plaque formation

A new LMU study shows how differently immune cells influence the formation of dangerous vascular deposits - and identifies miR-147 as a potential starting point for future therapies.

Fatty liver disease linked to higher risk of heart attacks

Researchers at Mass General Brigham Heart and Vascular Institute found that people with hepatic steatosis, commonly called "fatty liver disease," have a higher amount of noncalcified, rupture-prone coronary plaque and face nearly twice the rate of cardiovascular events compared to those without steatosis.

Tranexamic acid modestly reduces bleeding after cesarean delivery in women

Giving tranexamic acid to women with placenta praevia (when the placenta covers the cervical opening) undergoing cesarean birth leads to a significant yet modest reduction in severe bleeding after delivery with no evidence of an increase in serious adverse events, finds a trial from China published by The BMJ today.

Climate change increases stroke risk through extreme weather and pollution

The World Stroke Organization is warning that climate change poses an escalating threat to brain health, with extreme heat in particular increasing the risk of having a stroke and of patients dying from stroke.

Apixaban reduces complications, helps older adults spend more time at home after blood clots

Older adults recovering from serious blood clots often face long periods of hospitalization or rehabilitation due to a higher rate of recurrence.

Minimally-invasive stenting effectively treats painful post-thrombotic syndrome

A major multi-site clinical trial co-led by researchers at Washington University School of Medicine in St. Louis has shown that post-thrombotic syndrome - a common and often painful complication suffered by many people who have experienced blockages of major veins due to blood clots - can be effectively treated with a minimally invasive procedure.

New guidelines and follow-up standards improve pulmonary embolism outcomes

Pulmonary embolism, or PE, is a serious and sometimes life-threatening condition that occurs when a blood clot travels to the lungs and blocks blood flow.

Angioplasty improves symptoms in chronic total coronary occlusion patients

In what is believed to be the first randomized placebo-controlled trial of its kind, patients with a chronic total blockage of a coronary artery who received a nonsurgical procedure to reopen the artery showed statistically significant reductions in chest pain and improvements in quality of life compared with patients who received a placebo procedure.

Catheter-based approach improves prognosis in pulmonary embolism patients

Patients who had low doses of clot-buster drugs delivered directly to the site of a pulmonary embolism (PE) via a catheter using ultrasound to enhance their effect had significantly better outcomes than those who received standard systemic anticoagulants, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Apixaban safer than rivaroxaban for treating venous thrombosis

The first clinical trial to compare two commonly used drugs head-to-head for venous thrombosis treatment has found a clear winner: while both drugs work well to prevent recurrent blood clots, apixaban is safer than rivaroxaban, with fewer bleeding complications.
