If the patient is tired of cardiac discomfort, he or she must be put on bed rest immediately, under constant observation, for 30-45 minutes, to see if the patient’s clinical symptoms are relieved. If the clinical symptoms are not significantly relieved, the patient must immediately go to the hospital for treatment and examination, and the following examinations need to be completed: 1. It is recommended to complete an 18-lead electrocardiogram to clarify the function of the heart; 2. Cardiac enzymology should also be perfected; 3. It is recommended that the patient undergoes a cardiac color ultrasound to clarify the function of the heart, as well as whether or not the patient has any ventricular, atrial, or valvular insufficiencies. According to the above situation, certain medicines can be applied to alleviate the symptoms, such as taking coenzyme Q10 or certain traditional Chinese medicines, such as Compound Danshen Dropping Pills, Astragalus Ginseng Yiqi Dropping Pills, Tongxinluo Capsules and so on, all of which can alleviate the above symptoms. However, if there is obvious organic disease of the heart when perfecting the relevant examination, it is recommended to have further examination, such as coronary angiography of the heart and enhanced CT of the heart, for the next step of treatment.
