Blood pressure outside of clinic may better predict outcomes in black patients

(HealthDay)—Among African-Americans, higher daytime and nighttime systolic blood pressure (SBP) is associated with an increased risk for cardiovascular disease (CVD) events and all-cause mortality independent of blood pressure (BP) levels measured in the clinic, according to a study published online Aug. 14 in JAMA Cardiology. Yuichiro Yano, M.D., Ph.D., from Duke University in Durham, North

Non-invasive electrical stimulation alters blood flow in brain tumors

In a first-of-its kind study, neurologists at Beth Israel Deaconess Medical Center (BIDMC) tested the use of non-invasive electrical stimulation as a novel therapeutic approach to brain tumors. In an experiment published in Science Advances, the scientists—led by Emiliano Santarnecchi, Ph.D., principal investigator at the Berenson-Allen Center For Non-Invasive Brain Stimulation at BIDMC—demonstrated that applying

Even slightly elevated blood pressure early in pregnancy a bad sign

Even a small increase in blood pressure during your first trimester could spell bigger trouble later in your pregnancy, new research suggests. Those troubles can include gestational high blood pressure, which develops after the 20th week of pregnancy, and preeclampsia (high blood pressure and protein in the urine), the researchers explained. Both conditions increase the

Pressure difference and vortex flow of blood in heart chambers may signal heart dysfunction

Japanese scientists at Tokyo University of Agriculture and Technology (TUAT), Teikyo University of Science, and Juntendo University have found—in animal studies—a close relationship between vortex flow and pressure differences in the ventricles, or lower chambers, of the heart. The new information could inform the development of new markers for cardiovascular dysfunction that can lead to

Targeting inflammation to better understand dangerous blood clots

It’s the third deadliest cardiovascular diagnosis, but doctors are still often stumped to explain why 40% of patients experience unprovoked venous thromboembolism (VTE). And after a patient has dealt with these dangerous blood clots once, a second and subsequent events become much more likely. New research from a team of University of Michigan scientists may

Human protein produced in CHO-cells can save donor blood

Alpha-1-antitrypsin is a protein produced by the liver. The protein gets secreted to the blood stream, where it circulates the body to protect the lungs. However, some people are born with genetic disorders that hinders production of this protein. These patients can suffer from decreased lung function, liver diseases and shortness of breath. In the

Varicose veins unlikely to develop into blood clots

Similar to leaky pipes, veins, as they return blood to the heart, sometimes fail to close completely. They stretch out and subsequently leak near the surface of the skin, creating spider or varicose veins that may cause discomfort. Dr. Tanya Flohr, a vascular surgeon at Penn State Heart and Vascular Institute, said the majority of
