Not as uncommon as you might think. Every year in the U.S., approximately 395,000 cases of cardiac arrest occur outside of a hospital setting, in which less than 6 percent survive. Approximately 200,000 cardiac arrests occur each year in hospitals, and 24 percent of those patients survive. 3,000 to 5,000 of these cases occur among children, adolescents, and young adults. Overall, broken down that means about a one in eight (12.5%) chance in men and a one in 24 (4.17%) chance for women. This is much greater than the frequency of lung cancer. What's more is that most of the causes of cardiac arrest are trauma and drug related, with actual ongoing disease processes accounting for relatively few of these cases.
