Commotio cordis occurs mostly in boys and young men (average age 15), usually during sports, most frequently baseball, often despite a chest protector. It is usually caused by a projectile, but can also be caused by the blow of an elbow or other body part.
The number of uninsured Americans declined by 8.8 million in 2014, the first year the major insurance reforms of the Affordable Care Act (ACA) took effect, according to new federal survey of 98,000 adults released by the U.S. Census Bureau today.
We can safely say (that with an uninsured rate of about 40 million, and remember that is dropping under the ACA) that somewhere between 20,000 and 40,000 deaths occur each year due to lack of health insurance.
