| Popis: | Symptom index (SI), which represents the percentage of perceived gastroesophageal reflux-related symptoms that correlate with esophageal acid reflux events (pH4), has been suggested as a measure to improve diagnosis of gastroesophageal reflux (GER)-related noncardiac chest pain (NCCP). Because no study has evaluated the value of the symptom index in NCCP patients, data to support this claim have yet to be elucidated.To evaluate the value of SI in identifying gastroesophageal reflux disease (GERD)-related NCCP patients.Patients enrolled in this study were referred by a cardiologist after a comprehensive work-up excluded a cardiac cause for their chest pain. All patients underwent upper endoscopy to determine esophageal inflammation and 24-hour esophageal pH monitoring to assess esophageal acid exposure. Patients were instructed to record all chest pain episodes during the pH test. Patients with a positive SI (or =50%) underwent the proton pump inhibitors (PPI) test, which is a therapeutic trial using a short course of high dose PPI.A total of 94 patients with NCCP were included in this study. Forty-seven (50%) had either a positive upper endoscopy or an abnormal pH test and were considered GERD-Positive. Forty-seven patients (50%) had both tests negative and were considered GERD-Negative. Total number of reflux episodes and percent total, supine and upright time pH less than 4, were significantly higher in the GERD-Positive group as compared with the GERD-Negative group (P0.0001, P0.0001, P = 0.0045, and P0.0001 respectively). Only 9 (19.1%) patients in the GERD-Positive group and 5 (10.6%) patients in the GERD-Negative group had a positive SI (p = ns). Eight (89%) out of the 9 patients who had a positive SI in the GERD-Positive group and 2 (40%) out of 5 patients in the GERD-Negative group responded to the PPI test.Positive SI is relatively uncommon in NCCP patients, regardless if GERD is present or absent. Hence, symptom index provides very little improvement in diagnosing GERD-related NCCP. |
