Isolated Systolic Hypertension Indicates Heart Disease Risk for Younger Adults

February 12, 2015 9:32 am | News | Comments

High systolic blood pressure – the top number in a blood pressure reading – has long been considered an indicator of cardiovascular disease risk for adults over 50. But now a new Northwestern Medicine study suggests that it’s also important for younger adults.

Revolution in Imaging Tech Brings Heart Failure Molecule Into View

Beethoven’s Arrhythmias Likely Inspired Some of His Masterpieces

February 3, 2015 1:54 pm | by Cynthia Fox, Science Writer | Articles | Comments

"Washington University cardiologist Zachary Goldberger once made music out of heartbeats. Now, with a Beethoven scholar and a medical historian, he has discovered that three musical compositions that Beethoven created while stressed are arrhythmic in a way mirroring the composer's own probable heart arrhythmias."

Two Genetic Mutations May Interact to Lower Heart Attack Risk

February 3, 2015 1:24 pm | by Ohio State Univ. | News | Comments

Researchers have determined that two mutations on a single gene can interact in a way that lowers the carrier's risk for a heart attack.  The variants are found in a gene called DBH, which regulates an enzyme involved in the conversion of dopamine to norepinephrine - both of which are important chemical messengers and hormones.

Blueberries, Avocados and Cocoa Beans May Keep Cardiologists at Bay

January 20, 2015 5:21 pm | by Bioscience Technology Staff | Articles | Comments

Times have changed. It used to be that an apple a day kept the doctor away. But three recent studies indicate this mantra could be changed to “a blueberry- avocado-cocoa-bean-smoothie a day” keeps the doctor away—if the doctor is a cardiologist.

New Way to Model Sickle Cell Behavior

January 20, 2015 10:07 am | News | Comments

Patients with sickle cell disease often suffer from painful attacks known as vaso-occlusive crises, during which their sickle-shaped blood cells get stuck in tiny capillaries, depriving tissues of needed oxygen. Blood transfusions can sometimes prevent such attacks, but there are currently no good ways to predict when a vaso-occlusive crisis, which can last for several days, is imminent.

Stem Cells Faulty in Duchenne Muscular Dystrophy

December 17, 2014 4:03 pm | by Stanford University | News | Comments

Like human patients, mice with a form of Duchenne muscular dystrophy undergo progressive muscle degeneration and accumulate connective tissue as they age. Now, researchers at the Stanford University School of Medicine have found that the fault may lie at least partly in the stem cells that surround the muscle fibers.
