Cardiac arrest
In the United States, approximately 535,000 cases occur a year. About 13 per 10,000 people (326,000 or 61%) experience cardiac arrest outside of a hospital setting, while 209,000 (39%) occur within a hospital. Cardiac arrest becomes more common with age. It affects males more often than females. Via its tendency to cause atrial fibrillation, alcohol use tends to cause generalized heart problems as well. The percentage of people who survive out of hospital cardiac arrest with treatment by emergency medical services is about 8%. Many who survive have significant disability.
