What is silent ischaemia?

Silent ischemia occurs when the heart temporarily doesn’t receive enough blood (and thus oxygen), but the person with the oxygen-deprivation doesn’t notice any effects. Silent ischemia is related to angina, which is a reduction of oxygen-rich blood in the heart that causes chest pain and other related symptoms.

Is mild ischemia serious?

Myocardial ischemia can lead to serious complications, including: Heart attack. If a coronary artery becomes completely blocked, the lack of blood and oxygen can lead to a heart attack that destroys part of the heart muscle. The damage can be serious and sometimes fatal.

What is meant by silent ischemia?

Is ischemia permanent?

An ischemic stroke, also known as a cerebral infarction or brain attack, results when a blood vessel is occluded and the loss of brain function is permanent because the brain tissue dies (sometimes called necrosis). Ischemic strokes are the most common form of stroke.

What is silent ischemia and how does it occur?

Can you have ischemia without pain?

These people have ischemia without pain — silent ischemia. They may have a heart attack with no prior warning. People with angina also may have undiagnosed episodes of silent ischemia. In addition, people who have had previous heart attacks or those with diabetes are especially at risk for developing silent ischemia.
