Identifying the cause of recurrent chest pain may be difficult. Significant coronary artery disease must be excluded before patients can be assured that their symptoms are truly "noncardiac." A normal coronary angiogram is the most definitive test but this may not preclude the presence of a new "fly in the ointment," i.e., microvascular angina. Musculoskeletal pain syndromes, psychological problems, and esophageal disorders, including both esophageal motility disorders and
gastroesophageal reflux disease
, are the most common causes of noncardiac chest pain. Nearly 30% of these patients will have an esophageal motility disorder, although its clinical relevance in the asymptomatic patient is controversial. Simple, inexpensive, provocation tests (most commonly edrophonium, bethanechol, and/or balloon distention) have been developed to recreate motility-related chest pain in the laboratory. These tests can identify the esophagus as the source of pain, but in most cases they do not direct therapy. Other disadvantages of provocation tests include the lack of a gold standard reference point, side effects, and the need for placebo because of a subjective end point. Recently, ambulatory esophageal pH and pressure monitoring have been used to define precisely the cause of esophageal chest pain. These systems can record multiple episodes of pain for up to 24 hours in an outpatient setting and have shown that
gastroesophageal reflux
(rather than motility disorders) is the most common esophageal cause of pain. However, these studies also suggest that many episodes of chest pain do not have an identifiable esophageal cause. Furthermore, this equipment is expensive, uncomfortable, may alter normal activity, and is not useful in patients having infrequent pain episodes. Psychological disturbances should be carefully sought in any patient with noncardiac chest pain: Many patients have anxiety, depression, or
panic attacks
that may complicate or contribute to their reported symptoms. It is questionable if these patients need additional testing. Rather, the challenge of the future is to prove that the multitude of tests aid in the overall treatment and outcome of patients with noncardiac chest pain.

Recurring substernal chest pain is an important clinical problem, causing anxiety for patients and their physicians because of the fear of possible cardiac disease. The differential diagnosis includes coronary artery disease, oesophageal disorders such as acid reflux disease and motility disturbances, musculoskeletal problems, psychological disorders including
panic attacks
, and a new 'fly in the ointment'--microvascular angina. History alone usually cannot distinguish cardiac from non-cardiac chest pain. After exclusion of significant coronary artery disease, attention must be turned to oesophageal disorders, which may be seen in as many as 50% of these patients. Oesophageal motility disorders, particularly the nutcracker oesophagus, are common, but the relationship between pain and abnormal contraction pressures is not well established. Provocative tests such as edrophonium (Tensilon) and balloon distension help to identify the oesophagus as the source of chest pain but do not direct therapy. Recent studies with ambulatory oesophageal monitoring suggest that gastro-
oesophageal reflux
may be a more common cause of chest pain than motility disorders. This is an important finding as acid reflux is a treatable problem, while therapies for motility disorders may only worsen reflux disease. The recent observation that oesophageal disorders are frequently associated and interact with psychological disorders such as anxiety, depression, somatization and
panic attacks
complicates the evaluation and understanding of chest pain. How these various abnormalities may be linked is an unresolved issue. Increased central nervous system stimulation and altered visceral and/or central pain sensitivity could be the common factors. It is hoped that further research into these areas will lead to new understandings of and possible solutions to the complex problem of non-cardiac chest pain.

Noncardiac chest pain is a common but important clinical challenge with respect to diagnostic strategy as well as therapeutic intervention. The most common esophageal disorder associated with chest pain syndrome is
gastroesophageal reflux
; 24-hour ambulatory monitoring of esophageal pH and the determination of the symptom index are useful in patient evaluation. A high frequency of abnormal esophageal motility has been reported in noncardiac chest pain, but its clinical significance remains controversial. Patients with chest pain and normal coronary angiogram may have microvascular angina. Musculoskeletal conditions account for at least 10% of the cases of noncardiac chest pain. The potential effects of stress and altered psychological states in this phenomenon must be considered. The role of
panic attacks
in the production of pain needs to be clarified. Investigations to elucidate the exact cause of chest pain as well as its treatment should be individualized to the patient.

The epidemiology of NCCP is poorly described, and the available data are conflicting. Population-based studies on the prevalence of NCCP are rare; most studies have been hospital based. According to the limited studies available, the annual prevalence of NCCP is approximately 25%. Despite this significant burden, the impact and natural history of NCCP in the community has not been adequately explored. NCCP is presumed to bea heterogeneous condition. Hospital-based studies have suggested that
GERD
, esophageal spasm, psychiatric disease (including
panic attacks
), and musculoskeletal pain explain many cases of NCCP. However, unrecognized coronary artery disease and microvascular angina (cardiac syndrome X)also explain an unknown proportion of cases in the general population.Current studies suggest that NCCP is common in the general population and significantly affects QOL, yet only a minority seeks medical attention.The epidemiology of NCCP requires further study in the general population and in those attending the Emergency Department.

Night sweats has been defined as drenching sweats that require the patient to change bed clothes. In current studies night sweats appear in 30% of non-obstetric patients and affects approximately 60% of pregnant women. Differential diagnoses include infections, malignancy, medications, hot flashes and
panic attacks
, making of each patient a challenge. We present two patients with night sweating. After excluding systemic diseases the diagnosis of
gastroesophageal reflux
was made, with excellent response to anti-reflux treatment. The presentation of our two patients coupled with a deep literature review, underscores the importance of
gastroesophageal reflux
as a cause of night sweating.
