Noncardiac chest pain: the role of the cardiologist--a national survey.

Background: The current assumption is that noncardiac chest pain (NCCP) patients diagnosed by a cardiologist are commonly referred to a gastroenterologist for further evaluation. Thus far, there are no studies that assess the clinical approach and referral patterns of cardiologists when evaluating subjects with NCCP.

Aim: To determine the extent of involvement of cardiologists in the management of NCCP patients.

Methods: Cardiologists were randomly selected from the American College of Cardiology national membership list and sent a 20-item questionnaire that included demographic information, characteristics of practice, preferences of diagnostic tests, referral patterns, and treatment plans.

Results: A total of 246 (33%) cardiologists returned the questionnaire. A mean of 12.6% of patients were diagnosed with NCCP and 45.5% were treated by a cardiologist in the past 6 months. Of the NCCP patients that were referred, most ended up in the primary care physician clinic (45.9%) followed by gastroenterologist clinic (29.3%). Most cardiologists are either comfortable (35%) or very comfortable (43.1%) in diagnosing NCCP. Proton pump inhibitors (44.9%), lifestyle modifications (28.7%), and H2 blockers (11.8%) are the three most commonly used therapeutic modalities for NCCP.

Conclusion: Cardiologists manage about half of the diagnosed NCCP patients by themselves. Of those NCCP patients that are referred, cardiologists prefer to send them to a primary care physician rather than a gastroenterologist.
