Patient: In the middle of March this year, I had a dull pain in my chest for two consecutive days and a numbness in my hands. I was hospitalized locally and got better. How can I treat acute coronary syndrome? Thank you! Song Chengyun: Acute coronary syndrome includes unstable angina, acute ST elevation or non-elevation myocardial infarction. Some patients need to stay in hospital for observation or even resuscitation treatment, while others can go home for treatment after stabilization. The doctor has to make a full assessment before deciding how to treat. Patient: Thank you Dr. Song for your reply!
