Patient: Shortness of breath with chest tightness and slight pain when walking fast, and shortness of breath when mopping the floor. On one occasion, severe pain in the chest from 2:00 to 5:00 in the middle of the night. Usually the pain is occasional, but not severe. The disease has lasted about a month or so. It hasn’t been treated yet. I would like to ask Dr. Yang, in a case like mine, can I have conservative treatment, or do I need interventional treatment? Are there any sequelae to interventional treatment? Do I need to take medication for life after interventional treatment? Yang Ming: Can I do conservative treatment for coronary artery disease or do I need interventional treatment: This problem mainly depends on the degree of coronary stenosis. It is recommended to do coronary angiography in a regular hospital as soon as possible. Will there be sequelae of interventional treatment? For someone like you who is suspected of having coronary angina, the danger brought to you by interventional therapy is far less than the danger brought to you by untreated cardiac morbidity. Conversely, a safer intervention should not be given to someone who does not have the slightest symptom of angina because the risk of cardiac morbidity is too small. Do I need to take medication for life after interventional treatment? With or without intervention, once the diagnosis of coronary artery disease is established, lifelong medication is required. Coronary heart disease is a disease of the elderly, and anyone who gets old will get it at a certain point. Human beings cannot return to old age now, but will only get older, so we must rely on medication to fight aging.
