The next logical step in management of patients with undiagnosed chest pain is to consider a diagnosis of GERD. Now, 16 years later, these costs are likely much higher.ĭiagnosis of gastroesophageal reflux disease 23 This added to a total in excess of $315 million (US) for all noncardiac cases diagnosed per year in the United States. In 1989, an American study calculated that initial treatment of a patient with undiagnosed chest pain cost approximately $3500 (US) per year. The psychological and physical suffering of patients with undiagnosed chest pain costs the health care system a great deal. 18, 19 Chest pain can be perpetuated by secondary anxiety and this, together with avoidance behaviour, 20 results in a substantially diminished quality of life for undiagnosed patients. ![]() 9 These patients need a diagnosis and access to appropriate treatment. 9 Undiagnosed chest pain results in ongoing anxiety because patients continue to experience pain and often continue to believe there is a cardiac origin for their symptoms. Once a cardiac cause for the pain is judged unlikely, patients are often dismissed without further diagnostic efforts. Managing patients with undiagnosed chest pain is a real challenge. The importance of CAD as a cause of chest pain means clinicians often need to order electrocardiograms, serum troponin assays, and exercise stress tests when carefully searching for symptomatic CAD. A few carefully chosen diagnostic tests are often needed to support or refute a developing diagnosis. 16, 17 Patients consulting primary care physicians for nonurgent assessment of chest pain are even less likely to have CAD. 2, 7, 8 Only 30% of patients admitted to hospital for chest pain are found to have cardiac origins of their symptoms. 11Ĭardiac risk stratification is of little use, given that even in the highest risk groups, most patients’ chest pain is not caused by cardiac conditions (level II evidence). 15 Diaphoresis, a third heart sound, or hypotension might support the presence of ischemic heart disease, but have insufficient sensitivity and specificity to be helpful in most cases. 11, 13, 14 It has been reported that 51% of patients with proven acute myocardial infarction have chest wall tenderness. 11 The most common finding during examination of patients with chest pain is chest wall tenderness, 8 but this is another clinical feature of low value in excluding cardiac causes of symptoms. Similarly, physical examination rarely reveals clinical signs sufficiently specific to support an accurate diagnosis (level II evidence). 10 Hence, although patients’ history is a valuable starting point, it often fails to provide a definite diagnosis because symptoms generally have poor specificity in diagnosis of chest pain (level I evidence). Unfortunately, physicians are often unable to make an accurate diagnosis based solely on history because, for example, descriptions of chest pain of cardiac, upper gastrointestinal, or gallbladder origin can be identical. Historical features generally of greatest value include the quality, duration, and timing of pain, as well as its association with trauma, meals, respiration, or exertion.
