In female patients with vague left atrial pain, this condition is highly considered to be due to the presence of coronary artery disease and angina pectoris. If the patient is currently a young woman with no previous medical history, it cannot be ruled out that the discomfort is due to cardiac neurosis, or a disorder in the regulation of vegetative nerves, and it is impossible for the patient to be clearly aware of her left atrial pain. If the patient is so described, it is likely that the patient is suffering from anxiety or has a certain anxiety state. It is recommended to relax more and take appropriate oral medications such as Xingyue capsule and Shuhelian Xiejue capsule to relieve the symptoms. If the patient has a history of cold, cough, diarrhea, fever within the last three weeks, he should also check cardiac enzymes, electrocardiogram, cardiac ultrasound and blood tests to further clarify the presence of myocarditis.
