M62.2: Ischaemic infarction of muscle

Ischaemic infarction of muscle, simply put, is a condition where parts of a muscle die due to lack of blood. The root cause of this condition is usually a blockage in the blood vessels that supply oxygen and nutrients to the muscle, often due to a clot. When muscle tissues don't receive enough oxygenated blood, they can't function properly and could end up dying. The onset of symptoms would typically be rapid and severe, including intense pain and swelling in the affected muscle, along with potential weakness or inability to use the muscle. Over time, the muscle can become necrotic, meaning the tissue dies. This condition can occur in any muscle in the body, though it's most common in the heart, leading to what is known as a heart attack.
