Vasospastic Angina

Coronary spasm causing chest pain at rest, treated with targeted medications.

Vasospastic angina — sometimes called Prinzmetal angina or variant angina — is one form of chest pain in which a coronary artery temporarily constricts, restricting blood flow to the heart muscle. Unlike classical angina from fixed plaque, vasospastic episodes typically occur at rest, often in the early morning hours, and can occur in arteries that appear normal or only mildly diseased on angiography. The diagnosis is frequently missed because standard exercise testing may be normal and angiograms do not always reveal spasm. Recognizing and treating vasospastic angina matters because untreated episodes can produce dangerous arrhythmias or rarely heart attack. Dr. Kedan considers vasospasm in patients whose chest pain pattern does not fit obstructive coronary disease.

What Cardiolucent Evaluates

  • Detailed history of chest pain pattern, especially rest pain and circadian timing
  • EKG capture during episodes when possible
  • Ambulatory ECG monitoring to detect ST-segment changes during pain
  • POCUS at the visit and resting echocardiography
  • Cardiac CT angiography to rule out obstructive coronary disease
  • Coordination with Cedars-Sinai for provocative testing when diagnosis remains unclear
  • Review of triggers including tobacco, cocaine, stimulants, and certain medications

Common Symptoms

  • Chest pain or pressure occurring at rest, often in early morning hours
  • Episodes lasting several minutes, sometimes severe
  • Pain that often responds quickly to nitroglycerin
  • Symptoms triggered by cold exposure, emotional stress, or certain medications
  • Recurrent episodes in clusters separated by symptom-free periods
  • Less commonly, syncope or palpitations during episodes

Risk Factors

  • Tobacco use, current or past (strongest risk factor)
  • Cocaine and stimulant use
  • Migraine and Raynaud phenomenon
  • Age 40–65, often younger than typical coronary patients
  • Female sex (women may be overrepresented)
  • Asian ancestry has higher prevalence in some studies
  • Certain medications that can trigger spasm

How Cardiolucent Approaches Treatment

The cornerstone is calcium channel blockers, often combined with long-acting nitrates, which together prevent spasm in most patients. Complete avoidance of tobacco and stimulants is essential, since their use can defeat any medication regimen. Dr. Kedan also reviews other medications that can precipitate spasm and tailors therapy based on episode frequency and severity. For severe or refractory cases, more intensive regimens or coordination with electrophysiology for arrhythmia monitoring may be needed.

Common Questions

Frequently Asked Questions

What is vasospastic angina?
Vasospastic angina is chest pain caused by sudden constriction (spasm) of a coronary artery, which temporarily reduces blood flow to the heart muscle. It is also called Prinzmetal or variant angina.
How is it different from typical angina?
Typical angina is caused by fixed atherosclerotic plaque and is brought on by exertion. Vasospastic angina is caused by transient artery constriction and most often occurs at rest, frequently in the early morning. Standard exercise testing may be normal in vasospastic patients.
How is it diagnosed?
Diagnosis combines a characteristic history with EKG evidence of ST-segment changes during episodes, normal or near-normal coronary anatomy on imaging, and sometimes provocative testing in the catheterization lab. Dr. Kedan often uses ambulatory monitoring to try to capture ST changes during symptomatic episodes.
Why is vasospastic angina often missed?
Many patients have normal exercise tests, normal or only mildly abnormal angiograms, and intermittent symptoms that resolve before they can be documented. Without specifically considering the diagnosis, clinicians often label the chest pain as non-cardiac. Dr. Kedan considers vasospasm when the history fits even if standard tests are unrevealing.
Is vasospastic angina dangerous?
Most patients do well with appropriate treatment. Untreated, severe vasospasm can occasionally cause dangerous arrhythmias or rarely heart attack, so accurate diagnosis and consistent treatment matter.
How is it treated?
Calcium channel blockers are the cornerstone, often combined with long-acting nitrates. Complete avoidance of tobacco, cocaine, and stimulants is essential. Some patients require combination therapy or higher doses; refractory cases benefit from specialist evaluation.
Can I exercise?
Most patients with controlled vasospastic angina can exercise normally. Because cold exposure and abrupt exertion can sometimes trigger episodes, a graduated warm-up and avoidance of extreme cold can help. Dr. Kedan provides personalized guidance.
Will I always need medications?
Most patients benefit from long-term medical therapy because episodes can recur after treatment is stopped. Some patients have a more limited course, and Dr. Kedan reviews the regimen periodically with you.
What triggers should I avoid?
Tobacco of any kind is the single most important trigger to avoid. Cocaine, amphetamines, and certain over-the-counter decongestants can also provoke spasm. Some prescription medications can contribute, and Dr. Kedan reviews your medication list with this in mind.
How do I schedule a consultation?
