Chest pain is one of the most common symptoms responsible for emergency department and primary care office visits in the United States. Chest pain can be noncardiac and may be attributed to multiple causes. Esophageal disorders including reflux, motility and functional conditions, affect a large proportion of patients with NCCP and lead to significant morbidity. The use of HRM has changed the diagnostic approach to esophageal motility disorders. It is the most specific and sensitive test for diagnosing motor disorders and a promising procedure in detecting dysmotility disorders in patients with NCCP. Despite the increased sensitivity of HRM, the main indications for esophageal manometry exclude NCCP. This study assessed the percentage of undiagnosed esophageal motility disorders in patients with NCCP referred for high resolution manometry. Differences in HRM findings in patients with NCCP versus patients meeting AGA recommendations for the clinical use of esophageal manometry were also compared. A retrospective descriptive design was utilized. Two hundred-nineteen patient charts were reviewed. One hundred sixty-eight (77%) patients underwent HRM and met AGA recommendations for esophageal manometry; 51 (23%) patients underwent the procedure after receiving a NCCP diagnosis. Findings showed that 116 (69%) patients in the AGA group had abnormal findings while 52 (31%) did not. In the NCCP group 34 (67%) had abnormal findings compared to 17 (33%) who did not. To compare normal and abnormal HRM findings in patients with NCCP versus those meeting AGA criteria, Chi-Square analysis was performed between the groups. The results were not statistically significant (p = 0.10). iv There were no significant differences in the results of HRM in both groups indicating the findings on HRM are the same despite the indication for the procedure. The findings support the use of HRM as a diagnostic tool in patients with chest pain after cardiac workup and endoscopic evaluation. This indicates a possible need to update the AGA indications for esophageal manometry and increase the awareness among healthcare providers regarding the use of HRM in patients with chest pain. Implication for future research is also discussed.
