What is vasospasm?

Vasospasm is a sudden narrowing of an artery. It can occur in several places in your body:

  • Coronary vasospasm: a constriction of coronary artery in the heart, which can cause chest pain, heart attacks or other illnesses
  • Cerebral vasospasm: a narrowing of an artery in the brain

Causes of vasospasm

Cerebral vasospasm often occurs after an aneurysm bleeds. Coronary vasospasm is commonly a result of atherosclerosis.

Symptoms of vasospasm

Vasospasm is often symptomless. In that, your physician may on an X-ray of the affected blood vessels (angiogram). When symptoms do occur, they include lack of blood flow to the affected organ or, in coronary vasospasm, tightness and pain in the chest.


We generally treat vasospasm by administering fluids and using calcium channel blockers or other drugs to increase blood flow and widen the narrowed artery.
