Ms. Zheng, 55 years old. She was admitted to our department on September 20, 2009 at 9:00 pm due to recurrent pain in the throat and posterior sternum for 2 weeks, which worsened for 1 day. Because of the history of “pharyngitis and gastritis”, she had not paid attention to it. After admission, acute myocardial infarction was considered after examination and analysis, and coronary angiography was performed on the 21st to confirm thrombotic occlusion of LAD vessels. Now Ms. Zheng is recovering well, and she said, “I am very grateful to the doctor for the analysis of her condition and the timely treatment. People should pay attention to the atypical “ischemic chest pain” and not mistake it for the previous “stomach disease or laryngitis”. Come to the hospital in time.
