The most common causes of anterior chest and back pain, chest tightness, and shortness of breath are myocardial ischemia and cardiac insufficiency. The most common cause of myocardial ischemia is coronary artery disease, while for anterior chest with pain in the corresponding part of the back, angina attack or even myocardial infarction is often considered. For angina attack, the symptoms last from 1-5 minutes and up to 15 minutes, while myocardial infarction attack has severe pain and lasts long, often more than half an hour, and can be accompanied by nausea, vomiting, cold sweat, dyspnea, decreased blood pressure, heart failure and other symptoms. For anterior chest and posterior back pain, accompanied by chest tightness and shortness of breath, angina pectoris, or even myocardial infarction and cardiac insufficiency are often considered. It is recommended to give electrocardiogram, cardiac enzymes, troponin, B-type brain natriuretic peptide precursors, and coronary imaging to clarify the condition and give systematic treatment.
