More Americans hospitalized for cardiac arrest are surviving now compared with a decade ago, a new study finds… Many people die before ever reaching the hospital. And in fact, of the more than 300,000 Americans who go into cardiac arrest outside of a hospital each year, less than 8 percent survive. "So this does not say anything about the rates of mortality of all (cardiac arrest) resuscitation attempts," senior researcher Dr. Alejandro A. Rabinstein, of the Mayo Clinic in Rochester, Minnesota, said in an email.
