title: Patients dismissed from the hospital with a diagnosis of noncardiac chest pain: cardiac outcomes and health care utilization.
abstract: OBJECTIVE
  To determine the proportion of patients with noncardiac chest pain (NCCP) who see a gastroenterologist, the type and frequency of gastrointestinal (GI) and cardiac tests performed, and the frequency of cardiac death.
  
  
  METHODS
  A cohort of Olmsted County, Minnesota, residents presenting to the emergency department (ED) with chest pain between January 1, 1985, and December 31, 1992, was identified through the Rochester Epidemiology Project. We assessed the frequency of ED, cardiology, and gastroenterology visits and corresponding tests after a diagnosis of NCCP (n=320). We also assessed the frequency of cardiac events.
  
  
  RESULTS
  During follow-up, 49% of patients sought care in the ED, 42% had repeated cardiology evaluations, and 15% were seen by a gastroenterologist. Thirty-eight percent underwent esophagogastroduodenoscopy, but very few underwent manometry or a pH probe. Patients with NCCP of unknown origin had 3 times the rate of GI consultations as their counterparts with a GI disorder. Survival free of cardiac death in the subset with NCCP with a GI disorder was 90.2% at 10 years and 84.8% at 20 years, compared with 93.7% at 10 years and 88.1% at 20 years for the subset with NCCP of unknown origin.
  
  
  CONCLUSIONS
  The frequency of health care utilization in NCCP patients is high, but relatively few GI consultations and even fewer GI tests are performed. Patients dismissed from the hospital with NCCP continue to experience cardiac events, which may highlight a need for more aggressive cardiovascular risk factor management in this population.
