Hospitals battle heart attacks with new chest pain centers

Chest pain emergency centers are among the most popular new ambulatory care services being added in U.S. hospitals. In the past year, at least 80 hospitals have added such facilities, bringing the total to about 103 in 33 states, according to the Maryland cardiologist who pioneered the concept. Still, it remains to be seen whether these facilities will become a reliable long-term source of increased admissions.
