Occasionally, the plaque may rupture and form an embolus which travels with the blood-flow downstream to where the vessel narrows and eventually clogs the vessel lumen

Classification
By histopathology
Infarctions are divided into two types according to the amount of blood present:

White infarctions (anemic infarcts) affect solid organs such as the spleen, heart and kidneys wherein the solidity of the tissue substantially limits the amount of nutrients (blood/oxygen/glucose/fuel) that can flow into the area of ischaemic necrosis. Similar occlusion to blood flow and consequent necrosis can occur as a result of severe vasoconstriction as illustrated in severe Raynauds phenomenon that can lead to irreversible gangrene. Red infarctions (hemorrhagic infarcts) generally affect the lungs or other loose organs (testis, ovary, small intestines). The occlusion consists more of red blood cells and fibrin strands. Characteristics of red infarcts include:
occlusion of a vein
loose tissues that allow blood to collect in the infarcted zone
tissues with a dual circulatory system (lung, small intestines)
tissues previously congested from sluggish venous outflow
reperfusion (injury) of previously ischemic tissue that is associated with reperfusion-related diseases, such as myocardial infarction, stroke (cerebral infarction), shock-resuscitation, replantation surgery, frostbite, burns, and organ transplantation. By localization
Heart: Myocardial infarction (MI), commonly known as a heart attack, is an infarction of the heart, causing some heart cells to die. This is most commonly due to occlusion (blockage) of a coronary artery following the rupture of a vulnerable atherosclerotic plaque, which is an unstable collection of lipids (fatty acids) and white blood cells (especially macrophages) in the wall of an artery.
These include effort-based tests such as grip and pinch strength, diagnostic tests such as Finkelsteins test for De Quervains tendinitis, Phalens contortion, Tinels percussion for carpal tunnel syndrome, and nerve conduction velocity tests that show nerve compression in the wrist. Various imaging techniques can also be used to show nerve compression such as x-ray for the wrist, and MRI for the thoracic outlet and cervico-brachial areas. Utilization of routine imaging  is useful in early detection and treatment of overuse injuries in at risk populations, which is important in preventing long term adverse effects. Treatment
There are no quick fixes for RSI. Early diagnosis is critical to limiting damage. For Upper Limb Repetitive Strain Injury (RSI), Occupational Therapists create interventions that include education to facilitate ergonomics. This will minimize the possibility of an upper limb strain injury by learning the correct approach during facilitating functional task movements. The RICE treatment is used as the first treatment for many muscle strains, ligament sprains, or other bruises and injuries. RICE is used immediately after an injury happens and for the first 24 to 48 hours after the injury. These modalities can help reduce the swelling and pain. Commonly prescribed treatments for early-stage RSIs include analgesics, myofeedback, biofeedback, physical therapy, relaxation, and ultrasound therapy. Low-grade RSIs can sometimes resolve themselves if treatments begin shortly after the onset of symptoms. However, some RSIs may require more aggressive intervention including surgery and can persist for years.Although there are no "quick fixes" for RSI, there are effective approaches to its treatment and prevention.
