What Is an Arterial Spasm?
An arterial spasm, also called arterial vasospasm, is a sudden tightening or narrowing of an artery caused by contraction of the blood vessel wall. This temporary narrowing reduces blood flow and the amount of oxygen reaching nearby tissues. Depending on where it occurs, an arterial spasm can cause mild discomfort or become a serious medical condition requiring immediate treatment.
Arterial spasms may affect the heart, brain, fingers, toes, or other parts of the body.
Why Arterial Spasm Matters
Reduced blood flow caused by an arterial spasm can lead to chest pain, neurological symptoms, or tissue damage if prolonged. Prompt diagnosis helps identify the underlying cause and reduce the risk of complications.
Common Causes
- Coronary artery disease
- Smoking
- Cold temperatures
- Stress
- Certain medications
- Cocaine or stimulant drug use
- Subarachnoid hemorrhage (brain vasospasm)
Common Symptoms
- Chest pain
- Cold or pale fingers and toes
- Numbness or tingling
- Temporary weakness
- Headache
- Vision changes
- Pain during physical activity
How Is an Arterial Spasm Diagnosed?
Healthcare providers may diagnose arterial spasms using a physical examination, electrocardiogram (ECG), angiography, CT angiography, MRI, ultrasound, or other imaging studies depending on the affected artery.
How Is an Arterial Spasm Treated?
Treatment depends on the location and cause of the spasm. It may include medications that relax blood vessels, calcium channel blockers, nitrates, smoking cessation, avoiding triggers, and treatment of the underlying condition.
How Home Care Can Help
Home care professionals support medication adherence, encourage healthy lifestyle habits, monitor symptoms, educate individuals about avoiding known triggers, and recognize signs that require prompt medical evaluation.
Home Care Tip
If cold temperatures trigger symptoms, dress warmly and protect your hands and feet to help reduce episodes of arterial spasm.
