Ischemia is a situation in which there’s an insufficient provide of blood to a specific a part of the physique. This may be brought on by quite a lot of elements, together with a blockage of an artery, a narrowing of an artery, or a lower within the pumping means of the guts. When ischemia happens, the affected tissue is disadvantaged of oxygen and vitamins, which might result in cell demise and tissue harm.
Ischemia can happen in any a part of the physique, however it’s mostly seen within the coronary heart, mind, and limbs. Ischemic coronary heart illness, or coronary artery illness, is the main reason behind demise in the US. Ischemic stroke, or mind assault, is the third main reason behind demise in the US.
The signs of ischemia range relying on the situation of the affected tissue. Within the coronary heart, ischemia may cause chest ache, shortness of breath, and fatigue.
