The pain in the right side of the rib cage is first of all clearly not a manifestation of coronary heart disease typical angina. However, if the symptoms occur in adults, especially men with a history of smoking, frequent late nights, irregular life, abdominal obesity, fondness for greasy food, fondness for late night snacks, and little exercise, it is recommended that atypical angina of coronary artery disease, such as right-sided chest pain, shoulder pain, arm pain, toothache, etc., should be excluded first. If necessary, coronary CTA should be done to understand whether there is stenosis in blood vessels. In addition, detailed medical history should be taken, such as whether there is any recent trauma or impact, whether there is any soft tissue injury around the ribs, costochondritis, etc. It is very important to improve the examination in time, or to consult in respiratory department, thoracic surgery and other specialties for clear diagnosis and timely treatment.
