Unexplained chest/epigastric pain in patients with normal endoscopy as a predictor for ischemic heart disease and mortality: a Danish 10-year cohort study

Long-term complications to reflux disease in community practice. A 17-year cohort study of 4706 patients

OBJECTIVE

To examine the risk of developing strictures in patients with erosive and non-erosive gastroesophageal reflux disease in a community-based setting, since controlled trials indicate that the use of proton pump inhibitors renders the risk of strictures insignificant.

MATERIAL AND METHODS

A 17-year cohort study of 4706 patients referred to endoscopy due to upper GI symptoms, with a population comparison cohort of 47,060 individuals. All patients were followed and treated according to prevailing guidelines by their usual care provider. Main outcomes were relative risks (RR) and 95% confidence intervals (CI) for incident strictures and dilatations.

RESULTS

776 (16.5%) patients were diagnosed with erosive esophagitis, particularly men (61.2%). Over a period of 1-17 years (mean 10.5), 20 patients (2.6%) in the esophagitis group developed a peptic stricture, necessitating one or more dilatations in 16 patients (2.1%). Among the non-esophagitis patients, the incidences for both outcomes were 1.2%. Male gender doubled the risk of developing strictures, and alcohol abuse raised the risk four folds. Erosive patients had a risk of developing strictures eight times (95% CI: 5.0-13.0) higher than controls, whereas non-erosive patients' risk was 4.0 (95% CI: 2.8-5.7). The majority of strictures developed within the first 10 years after a diagnosis of esophagitis.

CONCLUSION

Patients with esophagitis had eight times higher risk of strictures than population controls and two times higher than dyspeptic patients without esophagitis. This indicates that long-term outcomes in general practice are poorer than in controlled trials, most likely due to a lack of compliance with medication.

A new method to assess perceived well-being among elderly people--a feasibility study

BACKGROUND

A simple but countable electronic device has been developed to gain reliable information on elderly patients' perceived well-being. The device has been tested and proven to be technically functional and countable. It was now tested in two care homes for the elderly and two private homes to evaluate if it provided solid information about the well-being of elderly persons. This report illustrates the practical usage of the device and shows its efficiency in gathering solid well-being information from the focus group.

METHODS

The test arrangement was carried out by assigning a group of volunteers (n = 10) in care homes for the elderly for two weeks. The time period was long enough to collect a sufficient amount of information to evaluate the perceived well-being of the test subjects. Perceived well-being was assessed by using a Con-Dis device and by filling out an attached questionnaire - RAI - at the same time. RAI consisted of questions concerning mood, pain and quality of life. A standardised RAVA questionnaire with 12 questions concerning test subject's health was also answered once during the two-week time period by each test subject. After the test period the data obtained by Con-Dis was compared with the findings collected using questionnaires.

RESULTS

A statistically significant correlation was found between perceived well-being (measured by Con-Dis) and questionnaire-based mood (r = 0,66, Pearson Correlation Coefficient) and quality of life (r = 0,68). No statistically significant correlation was found between perceived well-being and pain (r = 0,28). Technical functionality and feasibility of Con-Dis were good during the test period. Some problems arose because the test subjects were elderly and some in poor physical condition.

CONCLUSION

On the basis of the collected results, the Con-Dis device presented information on the test subjects' perceived well-being that appeared to correlate with certain aspects of their health status. The test subjects' mood and quality of life but not pain had a statistically significant association with the perceived well-being level measured by Con-Dis.

Non-cardiac chest pain: the long-term natural history and comparison with gastroesophageal reflux disease

OBJECTIVES

The source of most cases of non-cardiac chest pain (NCCP) is thought to be the esophagus. We reasoned that if the origin of NCCP is truly esophageal and not cardiac, the characteristics and survival of individuals with NCCP should be similar to those of individuals with benign esophageal disease, such as gastroesophageal reflux disease (GERD). The aim of this study was to compare the characteristics, natural history, and long-term survival of two well-defined groups, NCCP patients and GERD patients.

METHODS

From 1984 to 1996, patients with NCCP were referred for endoscopy by the cardiology service after a coronary angiography done for chest pain was reported by the cardiologist as negative. Patients with GERD were referred for endoscopy for one of the usual symptoms of acid reflux. The baseline endoscopy and referrals occurred in the pre-proton pump inhibitor (PPI) era, before and during the availability of only the histamine receptor antagonists (HRAs). Thus, the endoscopic findings reflected the untreated natural state of the gastrointestinal mucosa. Endoscopic exams, esophageal biopsy, endoscopic anatomy mapping, and data verification were carried out in the endoscopy lab by one of three endoscopists using predefined criteria. All results were recorded both by hand and by entry into a database storage program. Patients were followed by their primary care providers in their usual outpatient general medicine clinics. The Veterans Affairs Decentralized Hospital Computer Program (VA DHCP) storage system provided access to mortality data as well as details of all prescriptions filled since 1985.

RESULTS

During the 12-year enrollment period, 1,218 patients in the GERD group and 161 in the NCCP group were referred for endoscopy. The follow-up period ranged from 1-22 years (mean 9.8 years). The groups were similar in age, gender, smoking and alcohol habits, and use of aspirin and NSAIDs (non-steroidal anti-inflammatory drugs) (P=NS), but there was a greater proportion of blacks in the NCCP group (P<0.003). In every parameter, NCCP patients had a significantly lower prevalence of GERD-related findings such as endoscopic esophagitis (P<0.0001), Barrett's metaplasia (P=0.02), the development of esophageal adenocarcinoma, and hiatal hernia presence (P=0.0001). In patients with hiatal hernia, the size of the hernia was similar in both groups (P=0.94). In the NCCP group compared with the GERD group, there was a significantly higher prevalence of cardiac factors, such as coronary artery disease (P=0.03), and there was a trend toward greater cardiac clinic enrollment (P=0.08) and cardiac medication usage (P=0.06). The amount and duration of anti-GERD therapy, such as HRAs and PPIs, were significantly less in the NCCP group (P=0.0001 for PPIs and P=0.0002 for HRAs). The diagnosis of NCCP disappeared from the electronic hospital record in 96% of patients within 2 years of follow-up. There was no significant difference in survival between the GERD and NCCP groups (hazard ratio=1.1; CI=0.8-1.5); however, longer duration of follow-up in those with a greater number of events may make a difference in survival.

CONCLUSIONS

NCCP in most patients seems to be a short-lived event requiring extensive medical evaluation and having clinical characteristics significantly different from those associated with GERD. Patients with NCCP, confirmed by the absence of angiogram-documented coronary artery disease, who are referred for diagnostic endoscopy, have an excellent long-term benign prognosis, similar to patients with GERD.
