Text Box: GASTROESOPHAGEAL REFLUX AS A CAUSE OF “CARDIAC PAINS” IN CHILDREN Ulewicz-Filipowicz J1, Aleszewicz-Baranowska J2, Owczuk R1, Erecinski J2, Balcerska A1 1 Departement of Pediatrics, Hematology, Oncology and Endocrinology, Medical University of Gdansk, Poland 2 Department of Pediatric Cardiology, Medical University of Gdansk, Poland Chest pain determined as the “cardiac pain” are frequent reason for patient sending to pediatric cardiologists. The etiology of thoracalgia are diverse: musculo-sceletal, cardiac, psychogenic, originated from respiratory system or gastrointestinal tract We present the results of 24-hours pH-metry performed in 24 patients aged from 4,5 to 15,5 years, after exclusion by cardiologist cardiac, respiratory and musculo-sceletal springs of complaints. Basing on performed tests gastroesophageal reflux was diagnosed in 17 (70,8%) of 24 patients. In two cases the reflux was determined as severe, moderate and mild form of the disease was detected in 4 and 12 patients respectively. In 8 children we didn’t find any somatic cause of chest pain. The differentiation among psychogenic source of chest pain and the pain originated from gastrointestinal disorders, require the widening diagnostic procedure by pH-metry and gastroduodenoscopy. Our observation and literature review points at the increased number of patients with neurosal causes of thoracalgia (in our patients – 30%). Psychogenic origin of the chest pain can be identified only after exclusion all somatic causes of the symptom. 1847
