In 1909, Babcock first proposed the concept of chole-heartsyndrome, and in 1933, Mclemore et al. proved through practice and clinical evidence that dilatation of the gallbladder could cause angina pectoris, which was thought to be the result of vagal reflexes and was called “reflex angina pectoris”. “In 1977, BNHOTPa IIOB pointed out that the cause of cardiac dysfunction in patients with biliary disease was not only reflexive, but also influenced by various metabolic factors, and suggested the name of “biliary heart syndrome”. Since the 1980s, due to the high incidence of bile duct and gallbladder diseases, biliary heart syndrome is not uncommon in clinical practice. With the change of people’s dietary structure, the incidence of biliary diseases increases year by year, and biliary heart syndrome also increases, and has a tendency to be younger. Biliary heart syndrome refers to the simultaneous appearance of transient symptoms and signs of coronary heart disease in patients with biliary disease, often accompanying the acute attack of biliary disease, which can disappear automatically after the biliary disease is relieved. Patients with biliary heart syndrome do not have organic lesions of the coronary arteries and can be expected to return to normal after biliary disease is cured. It occurs more often in women than in men. What are the tests for biliary heart syndrome? Routine blood count, electrocardiogram, ultrasound, blood biochemistry. CT of the liver, gallbladder and spleen can be used to assist in the examination.
