Functional Chest Pain
Conditions
Brief summary
Non-cardiac chest pain (NCCP) in the absence of musculoskeletal abnormalities, major esophageal motor disorders, gastroesophageal reflux or eosinophilic esophagitis is called functional chest pain (FCP). Most likely multiple factors play a role, such as esophageal hypersensitivity and enhanced perception. Citalopram and other antidepressants are proven to be effective in the treatment of functional gastrointestinal disorders such as irritable bowel syndrome. With this trial the investigators want to assess the effect of citalopram on symptoms of chest pain in patients with functional chest pain.
Detailed description
Chest pain can be divided in cardiac or non-cardiac chest pain (NCCP). To establish the diagnosis NCCP, acute coronary disease has to be ruled out first. NCCP can be caused by functional chest pain (FCP). NCCP in the absence of musculoskeletal abnormalities, major esophageal motor disorders, gastroesophageal reflux or eosinophilic esophagitis is called FCP. The pathophysiology is not fully understood. Most likely multiple factors play a role, such as esophageal hypersensitivity and enhanced perception. Citalopram and other antidepressants are proven to be effective in the treatment of functional gastrointestinal disorders such as irritable bowel syndrome. However, available data regarding low dose antidepressants in functional chest pain is inconclusive. Moreover, all current evidence concerning the effect of low dose antidepressants in patients with functional chest pain is extracted from trials that pooled patients with different functional esophageal disorders. With this trial the investigators want to assess the effect of citalopram on symptoms of chest pain in patients with functional chest pain.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Global assessment of patient reported change in chest pain after 6 weeks of treatment. | 6 weeks after start of the study | Patients will be asked; Compared to the start of the treatment, how would you rate the chest pain now? * Completely resolved * Moderately better * Slightly better * No change * Slightly worse * Moderately worse * Much worse Patients who answered completely resolved or moderately better will be defined as treatment success. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Symptom frequency | Daily diary during the entire duration of the study (12 weeks) | Patients are asked to report the frequency of symptom episodes on a daily base |
| Symptom severity | Daily diary during the entire duration of the study (12 weeks) | Patients are asked to report the severity of every symptom episode on a daily base. The severity will be rated on a 4-point scale: mild (1, the symptom was well tolerated and did not last long) moderate (2, the symptom caused some discomfort, but did not interfere with usual activities), severe (3, the symptom caused a great deal of discomfort, and interfered with usual activities), disabling (4, the symptom was unbearable and interfered considerably with usual activities). |
| Chest pain will be scored on a 0-10 visual analog scale (VAS-score) | Baseline, 6 weeks and 12 weeks | Patients are asked to report the severity of the chest pain every 6 weeks |
| Global assessment of patient reported change in chest pain after 12 weeks of treatment. | 12 weeks after start of the study | Patients will be asked; Compared to the start of the treatment, how would you rate the chest pain now? * Completely resolved * Moderately better * Slightly better * No change * Slightly worse * Moderately worse * Much worse Patients who answered completely resolved or moderately better will be defined as treatment success. |
| Psychological comorbidity using the Hospital Anxiety and Depression Scale (HADS) | Baseline, 6 weeks and 12 weeks | Psychological comorbidity is assessed every 6 weeks |
| Adverse events/side effects | Adverse event reporting period is defined as the period following time of written informed consent up to 3 months after end of the observation period. | Patients are asked to report adverse events and side effects. |
| Health related quality of life measured using 36-Item Short Form Health Survey (SF36) | Baseline, 6 weeks and 12 weeks | The health related quality of life is measured every 6 weeks |
