Patients who have chest tightness but whose symptoms are relieved after exercise are highly considered to be suffering from precordial discomfort due to cardiac neurosis or disorders of vegetative nerve function regulation. Because exercise can distract the patient’s attention, for patients who have their own neurasthenia or anxiety or depression, the deeper the night and the quieter it is, the more likely it is to have uncomfortable symptoms such as chest tightness, shortness of breath, panic and palpitations. Moving around, doing chores or participating in outdoor activities or sports to distract the individual will instead ease the symptoms of precordial discomfort. Patients are advised to undergo initial screening with electrocardiogram, chest X-ray and cardiac ultrasound if necessary. For chest tightness caused by cardiac neurosis, it is recommended to combine with oral medications such as Shuhelian Xieyun capsule and Guanxin Danshen Dripping Pill to improve it.
