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.
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.

Surds are based on roots. Root 8 can be split into root 4 and root 2; as there's a root to 4, get that number, and multiply it by the remaining root. So root 8 = 2 root 2. Root 40 would be 2 root 10 Root 48 would be root 4, root 4, root 3 Root 48 = 4 root 3.
Carrot is a root vegetable.
The cube root of the square root is the sixth root. The sixth root of 729 = 3
root 8 = root 4 x root 2 = 2 root 2, root 18 = root 9 x root 2 = 3 root 2; 2 root 2 x 3 root 2 = 6 x 2 = 12
