Chest pain is a common clinical symptom with a lifetime incidence of 24.6% in the population. The causes of chest pain are complex, and different diseases can show the same or similar pain characteristics, which can easily lead to clinical misdiagnosis and mismanagement. Moreover, the onset of some chest pains is critical and requires timely diagnosis and treatment, otherwise it will bring serious consequences. In order to correctly diagnose and treat chest pain, reduce misdiagnosis and misdiagnosis, and develop a reasonable diagnosis and treatment process, we cooperate with other units to jointly launch a chest pain epidemiological survey. We hope that patients with various kinds of chest pain will consult us and we will record your medical history in detail and answer your questions patiently!
