How Do You Treat Vasospasm?

What medication is used to decrease vasospasm?


Nimodipine is a dihydropyridine agent that blocks voltage-gated calcium channels and has a dilatory effect on arterial smooth muscle.

It is the only FDA-approved agent for vasospasm with a half-life of about 9 h [6]..

How is coronary vasospasm diagnosed?

These tests are often enough for a diagnosis, but the only way to definitively diagnose coronary artery spasm is by doing an additional test called provocative testing . During provocative testing, doctors use specific drugs to cause or “provoke” a spasm, which allows them to diagnose the condition with certainty.

What does a vasospasm feel like?

When a vasospasm develops in the coronary artery, the main symptom is chest pain often described as constricting, crushing, pressure, squeezing or tightness.

Can vasospasm cause heart attack?

In someone with clogged coronary arteries or a weakened heart, though, vasospasm can throw the heart into a potentially dangerous rhythm. A coronary vasospasm can also rupture a fragile cholesterol-filled plaque inside an artery, setting off a full=blown heart attack.

Does caffeine cause vasospasm?

In vitro, caffeine has physiological effects on the concentration of intracellular calcium in the vascular smooth muscle and could induce coronary vasospasm; in vivo, caffeine reduces myocardial blood flow during exercise [97] .

How common are Vasospasms?

Vasospasm is the most common complication of SAH and is the main cause of delayed morbidity and mortality. It usually occurs 4 to 14 days after the initial accident, with a peak incidence at 7 days. Its rate of occurrence varies according to the authors from 40 to 70% 38. It is symptomatic in 17 to 40% of cases 10.

Is vasospasm a stroke?

Subarachnoid Hemorrhage After the hemorrhage, the blood can irritate the brain and cause the vessels in the brain to narrow or go into spasm, limiting blood flow and putting the brain at risk for stroke. This condition is called a cerebral vasospasm.

How is vasospasm treated after SAH?

In addition to angioplasty, vasodilating agents such as papaverine or verapamil, can be infused directly (intra-arterially) to relieve the spasm. Hypertension, hypervolemia, and hemodilution (triple-H therapy) is often utilized to prevent and treat cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH).

How do you stop Vasospasms?

Avoid nicotine and caffeine, as they can exacerbate the problem. If you still experience pain, try massaging your areola (the ring of pigmented skin that surrounds your nipple) with olive oil. You can also massage the chest muscles above your breasts before feedings, or during a vasospasm, for 60 seconds on each side.

How do you prevent vasospasm?

Maintenance of euvolemia and normal circulating blood volume is recommended to prevent vasospasm. In symptomatic vasospasm, induction of hypertension is recommended to achieve increased cerebral blood flow. Hypervolemia is no longer recommended as a measure to prevent vasospasm.

Is vasospasm a complication of cerebral aneurysm?

After a brain aneurysm ruptures, blood vessels in your brain may narrow erratically (vasospasm). This condition can limit blood flow to brain cells (ischemic stroke) and cause additional cell damage and loss.

Can you recover from vasospasm?

One-third of patients will survive with good recovery; one-third will survive with a disability; and one-third will die. Treatment focuses on stopping the bleeding, restoring normal blood flow, and preventing vasospasm.

What causes vasospasms in the brain?

Vasospasm occurs when a brain blood vessel narrows, blocking blood flow. It can occur in the two weeks following a subarachnoid hemorrhage or brain aneurysm. You are at greater risk for a cerebral vasospasm if you have had a recent subarachnoid hemorrhage or ruptured brain aneurysm.

How does nimodipine prevent vasospasm?

Nimodipine. Nimodipine is a dihydropyridine that blocks calcium influx through the L-type calcium channels. It is the most rigorously studied and only drug approved by the US Food and Drug Administration for use in treatment of vasospasm.

How long do Vasospasms last?

It typically begins 72 h following SAH, peaking at 6–8 days, and terminating 21 days post SAH. The severity of vasospasm is an important clinical risk factor for neurological deterioration and poor outcome.

Can your brain have a muscle spasm?

Your brain injury may cause the muscles in your body to become stiff, overactive, and difficult to stretch. The muscle may “spasm” or tighten suddenly. Doctors call this effect spasticity (pronounced spas-TIS-it-ee).
