Treating allergic rhinitis. Treatment for allergic rhinitis depends on how severe your symptoms are and how much they're affecting your everyday activities. In most cases treatment aims to relieve symptoms such as sneezing and a blocked or runny nose.
What is ischemic heart disease? Ischemic heart disease is a condition of recurring chest pain or discomfort that occurs when a part of the heart does not receive enough blood. This condition occurs most often during exertion or excitement, when the heart requires greater blood flow. Ischemic heart disease, also called coronary heart disease, is common in the United States and is a leading cause of death worldwide. Ischemic heart disease develops when cholesterol particles in the blood begin to accumulate on the walls of the arteries that supply blood to the heart. Eventually, deposits called plaques may form. These deposits narrow the arteries and eventually block the flow of blood.
Ischemia is the condition or state in which a tissue such as brain is subjected to hypoxia or low oxygen because of an obstruction of the arterial blood supply or inadequate blood flow. Brain ischemia can be broadly divided into two main classifications, global ischemia and focal ischemia. Global ischemia is the condition or state in which blood flow to the entire brain is transiently blocked, which results in delayed, selective neuronal death.
