Thrombosis

Thrombosis is the formation or presence of a thrombus (blood clot) inside a blood vessel.

What is Thrombosis?

Thrombosis is the process of a blood clot, also known as a thrombus, forming in a blood vessel. This clot can block or obstruct blood flow in the affected area, as well as cause serious complications if the clot moves to a crucial part of the circulatory system, such as the brain or the lungs.

Investigational anti-clotting drug reduces risk of second ischemic stroke without bleeding concerns

An investigational anti-clotting medication, asundexian, demonstrated a reduction in the risk of a second ischemic (clot-caused) stroke without raising bleeding concerns, according to a preliminary late-breaking science presentation at the American Stroke Association's International Stroke Conference 2026.

Hormonal contraceptives show differing heart risks among stressed women

Antonia Seligowski, PhD, of the Neurocardiac Effects of Stress & Trauma Laboratory within the Department of Psychiatry at Mass General Brigham, is the senior author of a paper published in JAMA Network Open, "Hormonal contraceptive use, stress disorders, and cardiovascular and thrombotic risk in women."

Scientists discover a non-classical platelet mechanism linked to severe infections

Platelets are small, anucleate blood cells that play an essential role in hemostasis. Their primary task is to recognize vascular injury, become activated, and aggregate via their surface receptor integrin αIIbβ3. This leads to the formation of a stable platelet plug that seals the wound and stops bleeding. When this process becomes dysregulated, however, it can result in vessel-occluding clots - so-called thromboses - which may cause myocardial infarction or stroke.

COVID-19 severity is linked to changes in mitochondrial DNA methylation

This study examined mitochondrial and nuclear-encoded mitochondrial DNA methylation in Indian patients with severe COVID-19 and found region-specific differential methylation linked to disease severity. Pathway analyses and protein assays implicated disrupted mitochondrial metabolism and dynamics, suggesting a role for mitochondrial epigenetic regulation in COVID-19 pathophysiology.

Advances in hemophilia gene therapy bring hope for pediatric patients

In the past three years, gene therapy has reshaped what's possible in hemophilia treatment for patients 18 and older. But a key question remains: How soon will these advances reach children?

What happens to your body when you eat takeaway food too often?

This study of 8,556 US adults shows that frequent takeaway food consumption is associated with a higher energy-adjusted Dietary Inflammatory Index and adverse cardiometabolic markers. The findings suggest that reducing takeaway intake and lowering dietary inflammatory potential may improve long-term cardiometabolic health.

TXA reduces the need for blood transfusion in patients undergoing high-risk non-cardiac surgery

When hospitals were randomly assigned to treat patients undergoing higher-risk non-cardiac surgery with tranexamic acid (TXA) or a placebo, patients who received TXA needed significantly fewer blood transfusions and saw no increase in potentially life-threatening blood clots (thrombosis) after 90 days of follow-up, according to research presented at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition.

Urine cfDNA patterns emerge as a promising tool for diagnosing bladder cancer

Researchers have discovered that analyzing specific patterns of cell-free DNA (cfDNA) fragmentation in a simple urine sample can effectively diagnose and stage bladder cancer, offering a much-needed alternative to invasive procedures like cystoscopies.

Magnetic microrobots guide drugs directly to blood clots

Every year, 12 million people worldwide suffer a stroke; many die or are permanently impaired. Currently, drugs are administered to dissolve the thrombus that blocks the blood vessel.

Shared genetic roots connect neurological and psychiatric disorders

In a groundbreaking study, researchers from the Centre for Precision Psychiatry at the University of Oslo and Oslo University Hospital have discovered extensive genetic links between neurological disorders like migraine, stroke and epilepsy, and psychiatric illnesses such as schizophrenia and depression.

Coronary artery calcium score could help predict overall health and all-cause mortality

In a new study of more than 40,000 patients, researchers at Intermountain Health in Salt Lake City have found that patients who have no evidence of calcium in their coronary arteries are not only significantly less likely to die from heart conditions – including heart attacks and heart failure– but also are at reduced risk of death from non-cardiac medical conditions.

Children face greater heart and inflammatory risks after COVID-19 infection than vaccination

The study is the largest of its kind in this population, and is published in The Lancet Child and Adolescent Health.

Sirolimus-eluting balloon strategy matches drug-eluting stents in large international PCI trial

New study results from a large international all-comer population of percutaneous coronary intervention (PCI) candidates found that utilizing a strategy of sirolimus-eluting balloons with bailout stenting only if necessary was noninferior to routine drug-eluting stent (DES) implantation as part of the treatment for de novo coronary artery disease.

Inflammation at the heart’s core: What clinicians and families can do now

Chronic low-grade inflammation is a key driver of cardiovascular disease, even when cholesterol is controlled. The ACC’s 2025 Scientific Statement highlights hsCRP as a routine risk marker and outlines lifestyle and pharmacologic anti-inflammatory strategies for prevention and treatment.

No advantage found in modulating antiplatelet therapy intensity after complex stenting

There was no benefit to modulating the intensity of antiplatelet therapy compared with standard antiplatelet therapy in high-risk patients who had undergone complex stenting procedures, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025.

Intravenous cangrelor provides rapid platelet inhibition in cardiogenic shock

Compared with crushed ticagrelor, intravenous cangrelor provided immediate, effective platelet inhibition, with no increase in major bleeding and lower mortality rates in patients with acute myocardial infarction and cardiogenic shock, according to late-breaking research presented in a Hot Line session today at ESC Congress 2025.

Early aspirin discontinuation safe after complete revascularization in acute MI

Among low-risk patients with acute MI who underwent early complete revascularization and received one month of dual antiplatelet therapy (DAPT), P2Y12 inhibitor monotherapy was noninferior to continued DAPT for adverse cardiovascular and cerebrovascular events, while reducing bleeding risk.
