Introduction Non-cardiac chest pain (NCCP) is mainly related to oesophageal disease, and in spite of being a common condition in Mexico, information regarding it is scarce. Aim To assess the clinical characteristics and health-related quality of life of patients with NCCP of presumed oesophageal origin. Material and methods Patients with NCCP of presumed oesophageal origin with no previous treatment were included in the study. Associated symptoms were assessed and upper gastrointestinal endoscopy and 24-hour oesophageal pH monitoring were performed to diagnose gastroesophageal reflux disease, while oesophageal manometry was used to determine oesophageal motility disorders. The SF-36 Health-Related Quality of Life (HR-QoL) questionnaire was completed and its results compared to a control group without oesophageal symptoms. Results The study included 33 patients, of which 61% were women, and the mean age was 46.1 (± 11.6) years. Causes of NCCP were gastroesophageal reflux disease in 48%, achalasia in 34%, and functional chest pain in 18%. The average progression time for chest pain was 24 (2-240) months, with ≤3 events/week in 52% of the patients. The most frequent accompanying symptoms were: regurgitation (81%), dysphagia (72%) and heartburn (66%). Patients with NCCP show deterioration in HR-QoL compared to the control group ( P = .01), regardless of chest pain aetiology. The most affected areas were general perception of health, emotional issues, and mental health sub-scale ( P > 0 .05). Conclusions In our population, patients with NCCP show deterioration in HR-QoL regardless of the aetiology, frequency, and accompanying symptoms.

ResumenIntroducciónEl dolor torácico no cardiaco (DTNC) se relaciona principalmente con enfermedades del esófago, y aunque se considera una condición común, en México la información aún es escasa.ObjetivoEvaluar las características clínicas y la calidad de vida relacionada con salud en pacientes con DTNC de presunto origen esofágico.Material y métodosSe incluyeron en el estudio pacientes con DTNC de presunto origen esofágico, sin tratamiento previo. Se evaluaron los síntomas asociados, se realizó endoscopia alta y monitorización de pH esofágico de 24h para establecer el diagnóstico de enfermedad por reflujo gastroesofágico, y para descartar trastornos en la motilidad esofágica se llevó a cabo manometría esofágica. Se aplicó el cuestionario de calidad de vida SF-36, y los resultados se compararon con un grupo control de sanos.ResultadosSe incluyeron 33 pacientes, el 61% mujeres, y la edad promedio fue 46.1 (±11.6) años. Las causas de DTNC fueron: enfermedad por reflujo gastroesofágico 48%, acalasia 34% y dolor torácico funcional 18%. El tiempo promedio de progresión del dolor torácico fue 24 (2-240) meses, con≤3 eventos/semana en el 52%. Los síntomas acompañantes más frecuentes fueron: regurgitaciones (81%), disfagia (72%) y pirosis (66%). Los pacientes con DTNC muestran deterioro en su calidad de vida comparado con el grupo control, independientemente de la etiología del dolor torácico. Los dominios más afectados son la percepción general de salud, problemas emocionales y la subescala de salud mental, sin diferencia estadística significativa (P > 0.05).ConclusionesEn nuestra población, los pacientes con DTNC muestran deterioro en su calidad de vida independientemente de la etiología, frecuencia y síntomas que acompañan al dolor torácico.AbstractIntroductionNon-cardiac chest pain (NCCP) is mainly related to oesophageal disease, and in spite of being a common condition in Mexico, information regarding it is scarce.AimTo assess the clinical characteristics and health-related quality of life of patients with NCCP of presumed oesophageal origin.Material and methodsPatients with NCCP of presumed oesophageal origin with no previous treatment were included in the study.
