Emergency medical services (EMS) agencies that adopt four or more critical best practices have higher rates of survival among cardiac arrest patients than their peers, a nationwide study co-led by a UT Southwestern Medical Center researcher found. The study, published in JAMA Cardiology, identified seven key practices related to simulation training, cardiopulmonary resuscitation, and transport that were associated with favorable neurological survival for out-of-hospital cardiac arrest (OHCA).

Scientists at Sanford Burnham Prebys and Salk Institute for Biological Studies have uncovered a new role for a protein known for its role in the brain helping control feelings of hunger or satiety, as well as in the liver to aid the body in maintaining a balance of energy during fasting. The new study shows that this protein also supports the maintenance of heart structure and function, but when it is overactive it causes thickening of the heart muscle, which is associated with heart disease.

High blood pressure affects about 45% of U.S. adults. In the 1970s, only about 50% of patients were aware of their hypertension. Today, 54% are aware of their high blood pressure, 40% are actively treated and 21% are actively controlled. As such, researchers alert health care providers that the old “silent killer” is alive and well.
