The purpose of this study was to investigate the prevalence of physical and mental disorder in the population of patients with myocardial bridge and to describe the relationship between clinical features and the occurrence of somatic disorder.

Myocardial bridge (MB), a congenital cardiac anomaly, is an unignored contribution to chest pain. Patients with MB often complain about chest discomfort more serious than the degree of vessel compression. The symptoms are also often inconsistence with the degree of coronary stenosis. Reports suggested that patients with MB may companioned with depression and anxiety. Moreover, patients with MB often have other systemic complaints including stomach pain, pain on the back, ear blockage, et al. Investigators assume that somatic symptom disorder (SSD) may play a part in aggregating the severity of symptoms. In order to screen SSD, investigators previously developed the Somatic Symptom Scale-China (SSS-CN) questionnaire. It is a somatic and psychological symptom scale which was developed based on the DSM-5 to assess a combination of psychological, behavioral and somatic symptoms. It is designed to assess the presence and severity of the symptoms. Investigators have validated its reliability and validity in a previous study. The purpose of this study was to investigate the prevalence of physical and mental disorder in the population of patients with MB and to describe the relationship between clinical features and the occurrence of somatic disorder.
