Patient: Every day from 3:00 am to 7:00 am, episodes of dull pain in the anterior chest area lasted for several minutes. He had an electrocardiogram at the county hospital and everything was normal. He was given an infusion of Danshen injection and lanosterin, etc. He did not have an attack for 5 days, but had an attack on the sixth day and took a quick-acting heart pill to stop the pain immediately. During the attacks, the chest pain and shortness of breath are particularly severe. I am taking Dior heart blood Kang Ginkgo biloba and other drugs every day. I don’t know if it is myocardial infarction, why I insist on using the medicine without relief, I don’t know what further examination is needed. Laboratory and examination results: ECG shows slow heart rate. Last seen at: Jingchuan County People’s Hospital Patient: Supplementary: ECG could not be uploaded because of inconvenient photo taking. The test results were: sinus bradycardia 58bpm, electrocardiographic axis not deviated, roughly normal ECG. Lipid and cardiac enzyme tests: total cholesterol 2.85 triglycerides 1.27 glutathione 12.10 a-hydroxybutyrate dehydrogenase 378.00 phosphocreatine kinase 84.50 creatine kinase isoenzyme 84.50 lactate dehydrogenase 264.40 From the symptoms, you are typical of coronary angina. There is no evidence that you have had a myocardial infarction, but there is a possibility of having one. Therefore, first you have to take aspirin 100mg once a night, simvastatin 10mg once a night (because your cholesterol is not high), betalactam 25mg twice a day and isosorbide mononitrate 40mg once a day. Get checked out at the hospital as soon as possible, even with low molecular heparin. Because you are young, it is better to perform coronary angiography and if necessary, stenting according to the results.
