The number of stroke hospitalizations peaked in 1997 and has been slowly declining ever since, according to Dr. Fang, who is affiliated with the Division for Heart Disease and Stroke Prevention at the Centers for Disease Control and Prevention.

Dr. Schumacher presented data that were derived from the Nationwide Inpatient Sample (NIS) from 1995 through 2004. The NIS is the largest publicly available database of hospital discharges available in the United States; it utilizes discharge data for approximately 20% of all discharges from nonfederal, acute care hospitals in the nation. …
