###Human: I have a discomfort under my sternum when I walk up a slope. What do you suggest? ###Assistant: Hello. I have reviewed your health query and have understood you may be having what is called ischemic heart disease. In this disease, the vessels supplying blood to the heart muscles itself, get clogged due to any reason. When there is the partial blockage (incomplete blockage) the patient does not feel pain all the times. But when there is more demand (as you walk on the inclined area, do strenuous physical work, climb stairs, etc.), the heart has to pump more and more blood to the body. But there is no much blood supply to the heart's own muscles. This causes a debt of blood and so oxygen to the heart itself and causes ischemic pain in the heart. You feel a discomfort due to all of this (this is the pathophysiology of this issue in simple words). You may feel free to add your latest reports to assist in this case. I would definitely be happy to review and get back to you as soon as possible. We may proceed from there later on. Regards. For further queries consult a cardiologist online -->
