Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

Pirtobrutinib shows superior outcomes compared to common first-line combination treatment for CLL/SLL

In a new trial, the Bruton tyrosine kinase (BTK) inhibitor pirtobrutinib increased the rate of survival without disease progression and was well tolerated with a more favorable safety profile when compared with bendamustine plus rituximab (BR) in patients with previously untreated chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL).

Sterilized fermented beverage targets obesity and type 2 diabetes pathways in computational study

Researchers profiled a terminally sterilized probiotic-fermented MFH beverage and identified aporphine alkaloids and flavonoids with favorable predicted ADMET properties. Integrated network pharmacology, molecular docking, and 100-ns MD simulations suggest multi-target engagement of metabolic-inflammatory pathways relevant to obesity and type 2 diabetes.

Nanoflower-treated stem cells deliver healthier mitochondria to stressed cells

This study shows that vacancy-engineered MoS₂ nanoflowers drive mitochondrial biogenesis in human mesenchymal stem cells by activating SIRT1–PGC-1α signaling and reducing oxidative stress. These treated cells transfer more functional mitochondria to injured recipient cells, restoring energy metabolism and redox balance in multiple in vitro models.

Doctors warn about cardiovascular dangers from excessive energy drink use

Downing several strong energy drinks every day may pose a serious stroke risk, doctors have warned in the journal BMJ Case Reports, after treating an otherwise fit and healthy man in his 50s with a daily 8-can habit and exceedingly high blood pressure.

Gut microbe metabolite TMA improves blood sugar by shutting down a key inflammatory switch

Researchers identified trimethylamine (TMA) as a gut microbe–derived metabolite that directly inhibits IRAK4 to reduce metabolic inflammation and improve glycaemic control in high-fat-diet-fed mice. Choline-driven increases in TMA production replicated these benefits, revealing a host–microbe signaling axis with therapeutic potential for obesity-associated insulin resistance.

Brain function discovery helps explain why childhood adversity raises metabolic disease risk in women

McGill University researchers have identified a brain function that helps explain why childhood stress raises metabolic health risks for some women later in life.

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.

High BMI and poor physical fitness in adolescence linked to severe bacterial infections in adulthood

High BMI and poor physical fitness during later adolescence increase the risk of both contracting and dying from sepsis and other severe bacterial infections in adulthood, according to a study from the University of Gothenburg.

Online reference library provides a more accurate picture of drug exposure

Doctors and researchers try to understand what medications a person has taken by asking patients directly or by looking at medical records. But this information is often incomplete.

Hotter days and nights are already stealing sleep across the U.S.

Rising nighttime and daytime temperatures are associated with reduced sleep duration, poorer sleep continuity, delayed sleep onset, and altered sleep stages in a large U.S. cohort tracked with wearable devices. Vulnerability is greatest among adults aged 40–50 years, females, people with lower socioeconomic status, chronic conditions, and those living in marine climate zones, with climate change projected to further magnify sleep loss.

JAX wins $30 million contract to create computational "digital twins" of the human heart

Developing new drugs is one of the riskiest and most expensive endeavors in science. Today, The Jackson Laboratory (JAX) announced a bold initiative to improve that trajectory, powered by an up to $30 million contract from the Advanced Research Projects Agency for Health (ARPA-H) Computational ADME-Tox and Physiology Analysis for Safer Therapeutics (CATALYST) program.

Study reveals the hidden toll of sudden cardiac death in type 1 and type 2 diabetes

A Danish nationwide study found that people with type 1 and type 2 diabetes have markedly higher rates of sudden cardiac death than the general population, especially at younger ages. At age 30, people with diabetes lose many years of life, with several of those years specifically attributable to sudden cardiac death.

Evidence grows for pirtobrutinib as a safer and effective alternative for CLL and SLL

Pirtobrutinib, a non-covalent Bruton tyrosine kinase (BTK) inhibitor, met the primary endpoint for non-inferiority in terms of overall response rate in the first head-to-head comparison with ibrutinib, a covalent BTK inhibitor.
