Chest pain 'often due to oesophagus problems'
29 November 2004:- Although recurrent chest pain is often thought to be a sign of heart problems, it is also a common symptom of gastro-esophageal reflux disease (GERD), study findings from Chile suggest.
"Recurrent chest pain (RCP) is a frequent consultation cause because it is generally associated with cardiac illness," Dr Carlos Manterola, from Universidad de La Frontera in Temuco, and co-authors observe.
To assess in how many patients complaining of RCP the underlying problems were associated with the oesophagus, the team carried out a number of tests on 127 people suffering from chest pain at least once a month.
Depending upon individual's reactions to a battery of tests, the likelihood that their chest pain was due to oesophageal problems was classified as "probable", "possible" or "unlikely".
Writing in the journal Diseases of the Esophagus, the researchers report that 38.2% of patients had a probable oesophageal cause of RCP, while oesophageal dysfunction was considered a possible cause in 42.3% and unlikely in 19.5%.
Of the patients suffering from RCP because of oesophageal problems, 44.7% had GERD, 26.8% had GERD with a secondary dysfunction of the oesophagus and 8.9% had an oesophageal dysfunction alone.
In addition, patients suffering from pain because of oesophageal problems had a significantly longer duration of pain than those with RCP due to other causes (37.4 vs 31.3 months).
"Almost 80% of the patients being studied had RCP that was at least possibly of esophageal origin," Dr Manterola and his team conclude.

Chest pain should not stop esophageal disease patients from exercising
22 December 2005:- Irish researchers have found that exercise is unlikely to worsen chest pain in patients with oesophageal disorders, although it may induce acid reflux and thereby chest pain in those with gastro-oesophageal disease (GORD).[ or GERD]
This was not the case for patients with "nutcracker oesophagus," who experience powerful swallowing contractions or for those with diffuse oesophageal spasm, which is characterised by chest pain and difficulty in swallowing.
For the investigation, Dr John Reynolds, from St James' Hospital in Dublin, and colleagues measured the pressure inside the oesophagus and the level of acid, as an indication of acid reflux that can cause chest pain, in 16 patients with nutcracker oesophagus, five with diffuse oesophageal spasm, 75 with GORD, and 39 healthy individuals.
The assessments were carried out before, during and after moderate exercise �?a brisk 5-minute walk at 4 km/h.
Moderate exercise did not appear to exacerbate symptoms in the patients, suggesting that the non-cardiac chest pain felt by patients with oesophageal disorders during moderate exercise is unlikely to be related to their primary symptoms, ie, the discordant oesophageal muscle contractions.
There were also no changes in levels of acid reflux during exercise for patients with nutcracker oesophagus or diffuse oesophageal spasm, but exercise did provoke acid reflux in 13 of the patients with GORD. None of these individuals had evidence of reflux at the start of exercising.
The findings support a role for acid reflux as a cause of chest pain for those who already have abnormal acid levels, such as individuals with GORD, but "the cause of chest pain in individuals with esophageal disorders without reflux remains unclear, the investigators conclude in the journal Diseases of the Esophagus.
