What causes ischemia?
ischemia is a condition in which blood is not supplied with enough oxygen to the main organ and most often affects the heart or brain. It occurs when blood flow is blocked or when blood flowing to the organ has an extremely low oxygen content. All body tissues need oxygen to function, so ischemia can lead to significant damage or even off the organ. The causes of ischemia include anemia of sickle cells, ventricular tachycardia, blood vessel compression and blood clots. This condition can also cause extremely low blood pressure, congenital heart defects and plaque accumulation in arteries.
Anemia of sickle cells can cause this condition because irregularly shaped or sickle blood cells can easily clot and block blood flow rich in oxygen into the heart, lung or brain. In rare cases, the precipitate may block the passage of oxygen to other organs such as the liver, causing significant damage. Most people who have anemia of sickle cells, use curse drugs,to avoid ischemia.
ventricular tachycardia
Ventricular tachycardia is a number of sudden irregular heart rhythms that can cause the heart to work incorrectly or in the most serious cases completely stop. The resulting complications may include ischemia, as irregular heart function can also inhibit oxygen flow. In cardiac death due to ventricular tachycardia, the heart stops completely and relieves the whole body of oxygen. Although a person can be revived using a defibrillator, lengthy oxygen deprivation can cause damage to the main organs.
compressed blood vessels
growth in the body can cause blood vessels to compress. Tumors can push the main arteries and prevent free blood flow rich in oxygen and lead to ischemia. Where other factors do not exist, ischemic episodes may indicate the presence of cancer or large, benigntumors.
Blood clots
Blood clots can be caused by a high number of plates or surgical procedures, or may occur in people who use excess blood clotting agents. In addition, blood clots can form in the feet of people who for any reason are inactive. In very rare cases, blood clots may form in the feet during long flights of the aircraft, causing almost immediate ischemia. Blood clots are often too small to block veins and arteries, but sometimes a large clot can block blood flow to the main organ, causing great damage.
low blood pressure
Theperson suffering from a heart attack usually shows extremely low blood pressure, indicating that the body tissues do not receive enough oxyne. Untreated and undiagnosed heart attacks can slow down the blood flow enough to form clots, creating ischemic conditions. People who repeatThese may be at greater risk for this condition.
congenital heart defects
Someone who has a congenital heart defect is also exposed to an increased risk of ischemia due to precipitation, both before and after reparative surgery. Some people who have congenital heart defects are immediately threatened by ischemia at birth. This could be caused by arteries that are not created or connected correctly, or because one or more arteries are missing.
Plaque accumulation in arteries
Atherosclerosis is a narrowing of arteries caused by plaque accumulation. This is often seen in older people and can usually be corrected. However, this narrowing is not always detected, and ischemia could first be present when the artery is so completely blocking that blood cannot get into the brain or lungs. Narrow passages also facilitate the blood of the clot and completely block the arteries.
possible treatment
Some procedures and treatment are used to prevent or repair ischemia. People who are prone to iNfarkts or blood clots usually receive appropriate medicines to reduce the risk of ischemia. Plaque accumulation can often be controlled by medicines and diet that reduces cholesterol. Episodes of ventricular tachycardia can be treated either by drug control or implanted pacemaker or defibrillator. Surgical correction of congenital defects can create normal blood flow patterns and any tumors that inhibit blood flow are removed whenever possible.
