Vasospasm-- Narrowing of a blood vessel caused by a spasm of the smooth muscle of the vessel wall.
papaverine
Sudden contraction of the smooth muscle of a blood vessel is vasospasm. It can be due to body response to hemorrhage or as an effect of drugs. Coronary Vasospasm can cause Ischemic heart disease (prinzmetal angina) or even MI
Serotonin to continue the vasospasm.
The term means a tightening of a blood vessel. Vaso-=vessel + spasm=constriction. The root of the word is vaso-
In general, during conditions in which the vascular system suddenly loses a large amount of its volume (hemorrhagic stroke, trauma)
likely due to coronary artery vasospasm, which can result in transient ischemia. Nitroglycerin dilates coronary arteries, increasing blood flow to the affected area and relieving the spasm-induced wall motion abnormality. It is important to investigate the underlying cause of vasospasm and address any coronary artery disease risk factors.
Though surgery can sometimes be used for treatment of coronary vasospasm, it is usually reserved for very serious cases which a) do not respond to medication alone, and b) are associated usually with some obstructing plaque, causing life-threatening oxygen starvation in the tissues of the heart. Results have been mixed when surgery is used to treat coronary vasospasm, so it is usually employed as a last resort.
underlying life long heart problem, congenital heart problem, vasospasm, or problem with other systems like liver or kidney failure including drug and or alcohol induced. also morbid obesity and diabetes could play a role.
Iodinated contrast is warmed before administration to improve patient comfort and reduce the likelihood of adverse reactions such as cold-induced vasospasm and discomfort at the injection site. Warming the contrast can also help prevent issues like muscle cramping and ensure optimal viscosity for smooth administration.

According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 1 words with the pattern -A--S-A-M. That is, nine letter words with 2nd letter A and 5th letter S and 7th letter A and 9th letter M. In alphabetical order, they are: vasospasm
Nicotine, the active ingredient in tobacco, is a stimulant compound. For those individuals who are already predisposed to heart disease and coronary artery narrowing, nicotine stimulation can cause coronary artery vasospasm and attacks of angina pain. Smoking cigarettes is a known risk factory for coronary artery disease.
