Vascular spasms temporary limit blood flow to tissue supplied by that vessel. The most common symptom is pain. Other symptoms are caused by lack of proper circulation and will vary depending on the specific organ affected:
When the spasm affects circulation in a limb, there may be pallor and a sensation of cold in that arm or leg. Limb function and movement will be impaired.
When the spasm affects circulation in the heart, there may be symptoms similar to a heart attack and irregular heartbeats. Other names for chest pain resulting from vascular spasm are Prinzmetal's angina and variant angina.
Signs and tests
These vary depending on the affected organ.
Definition Coronary artery spasm is a temporary, sudden narrowing of one of the coronary arteries (the arteries that supply blood to the heart). The spasm slows or stops blood flow through the artery and starves part of the heart of oxygen-rich blood. Alternative Names Variant angina; Angina - variant; Prinzmetal's angina Causes, incidence, and risk factors The spasm often occurs in coronary arteries that have not become hardened due to plaque buildup ( atherosclerosis ). However, it also can occur in arteries with plaque buildup. A contraction (squeezing) of muscles in the artery wall causes these spasms in the arteries. The contraction occurs in just one area of the artery. The coronary artery may appear normal during angiography , but it does not function normally. Coronary artery spasm affects approximately 4 out of 100,000 people. About 2% of patients with angina have coronary artery spasm. Coronary artery spasm occurs most commonly in people who smoke or who have high cholesterol or high ...
Definition Muscle function loss is when a muscle doesn't work or move normally. The medical term for complete loss of muscle function is paralysis. Alternative Names Paralysis; Paresis; Loss of movement; Motor dysfunction Considerations Loss of muscle function may be caused by: A disease of the muscle itself (myopathy) A disease of the nervous system: nerve damage (neuropathy), or spinal cord injury, or brain damage ( stroke or other brain injury) The loss of muscle function after these types of events can be severe, and often will not completely return. Paralysis can be temporary or permanent. It can affect a small area (localized) or be widespread (generalized). It may affect one side (unilateral) or both sides (bilateral). If the paralysis affects the lower half of the body and both legs it is called paraplegia. It if affects both arms and legs, it is called quadriplegia. If the paralysis affects the muscles that cause breathing, it is quickly life threatening. Common Causes Diseases of the mus...
