The door‐to‐balloon (D2B) time (the time it takes for a hospital to treat a heart attack patient after he or she arrives at the hospital) has fallen significantly since the launch of the D2B Alliance campaign in 2006. The biggest improvements were observed in groups that initially had the worst times, including patients over 75 years of age, women, and blacks. Researchers analyzed nationwide hospital data, collected by the Centers for Medicare & Medicaid Services, from more than 300,000 patients, from January 1, 2005, to September 30, 2010. The recent progress stems from a nationwide effort between federal agencies, healthcare organizations and doctors to improve heart attack care and outcome by accelerating treatment.
