Having diabetes doubles a person’s risk of dying after a heart attack, but the reason for the increased risk is not clear. A new University of Iowa study suggests the link may lie in the over-activation of an important heart enzyme, which leads to death of pacemaker cells in the heart, abnormal heart rhythm, and increased risk of sudden death in diabetic mice following a heart attack.

More children are surviving in-hospital cardiac arrest than they did one decade ago, according to a University of Iowa-led study of data from hospitals using resuscitation guidelines from the American Heart Association.

Children who had in-hospital cardiac arrest in 2009, were three times more likely to survive than children who had cardiac arrests in 2000. In addition, among surviving children, the risk of severe brain damage appears to have remained unchanged during this period. Story
A University of Iowa study shows that CaM kinase II enzyme triggers heart cell death by making the cells’ energy-producing mitochondria leaky. Inhibiting the enzyme in mitochondria protected mice from heart cell death during heart attack and other forms of heart stress. The findings could lead to better therapies for common forms of heart disease. Story
