Ischemic Heart Disease - Oren Zarif - Ischemic
Ischemic heart disease is an ailment in which the heart muscle is deprived of blood supply. In some cases, it may be caused by a thrombus on the atherosclerotic plaque, or it may be caused by a coronary spasm. If either causes the condition, it will resolve as soon as the thrombus spontaneously lyses or the spasm relaxes. Changes in supply and demand cause ischemia.

There are several risk factors for ischemic disease, but not everyone with those risk factors will experience it. Ischemic stroke requires immediate medical attention, so early detection and treatment is vital. Treatments involve surgery or other means of restoring blood flow. In severe cases, surgeries may be necessary to remove dead tissue or repair injured areas. In general, treatment focuses on prevention of future ischemia. This type of stroke is characterized by limited movement, speech and neurological function.

Early ischemic changes are best demonstrated with ultrastructural studies. Electron microscopy is particularly sensitive, but requires very fresh tissue and is prone to sampling errors. Fortunately, electron microscopic evaluation can be combined with morphometric analysis to quantify ischemic injury. Nonetheless, this type of assessment is not ideal for predicting ischemic heart disease. Whether it is infarct-associated, or a result of a broader inflammatory response is crucial in determining the treatment.

Whenever an organ is suffering from ischemic disease, blood flow is reduced to that area. This is caused by the buildup of plaque or atherosclerotic plaque in the artery that supplies it. This means that the organs are not getting the necessary amount of blood and oxygen to maintain normal functioning. Eventually, the tissues of the body will die as a result of this lack of blood supply. This is known as an "infarction" and can be life-threatening.

In the case of a coronary artery occlusion, ischemia will cause a fall in coronary venous oxygen saturation, decreased ATP production, and dyskinesis. Within a minute or so, the coronary artery narrowing will result in a gradual increase in end-diastolic and systolic pressures. In severe cases, ischemia can develop rapidly, causing chest pain and other symptoms.

Treatment for an ischemic episode will vary, and may include angioplasty, coronary bypass surgery, or thrombolytic medication therapy. Patients with IHD are more likely to suffer another episode if they do not take medications to prevent them. Some medications may be prescribed by a cardiologist, such as aspirin or beta-blockers. In severe cases, a coronary artery bypass is recommended to redirect the blood flow.

Ischemic heart disease is a life-threatening condition and should not be ignored. Untreated, it can lead to life-threatening complications. Follow a treatment plan developed by a healthcare professional and maintain regular contact with your doctor. As with any condition, regular medical checkups will reduce the chances of an ischemic episode. There are two types of ischemia. In the first, the heart muscle suffers reduced blood supply and may die. In the latter, a heart attack is caused by a sudden blockage of the heart artery.

Ischemic heart disease is caused by atherosclerosis. This condition affects blood flow by hardening the walls of the arteries. The buildup of plaque, a form of fat, makes them narrow. Narrowed arteries prevent adequate blood flow, similar to the plumbing in an old house. Ischemic heart disease is a life-threatening condition that can be treated. And, because ischemia is not contagious, it is often treatable with medical intervention.

A person can have both types of strokes. A transient ischemic attack is a warning sign of a future ischemic stroke. If it is not treated, it may lead to a stroke. It may also be a symptom of another condition. If you're not sure which type of stroke you have, it's best to contact a medical professional right away. A doctor will diagnose and treat the symptoms.
