The human heart is a remarkable muscle, beating more than 2 billion times over the average life span. But the heart's efficiency can decrease over time. One major contributor to this decreased function is cardiac hypertrophy -- a thickening of the heart muscle, resulting in a decrease in the size of the left and right ventricles. This makes the heart work harder and pump … [Read more...]

Administering heart resuscitation drugs to patients whose cardiac arrest is witnessed at the time of the attack can improve survival, but needs to be done through an IV line rather than directly into bone marrow as is more commonly done by paramedics, a new study involving UT Southwestern Medical Center emergency physicians and Dallas-Fort Worth Emergency Medical Services (EMS) … [Read more...]
