What is the difference between variant and unstable angina?
Unstable angina occurs suddenly and worsens over time. Variant angina (Prinzmetal) – occurs at rest without any underlying coronary artery disease.

How do you diagnose variant angina?
Diagnosis of Variant Angina Confirmation is by provocative testing with ergonovine or acetylcholine, which may precipitate coronary artery spasm. Coronary artery spasm is identified by finding significant ST-segment elevation on ECG or by observation of a reversible spasm during cardiac catheterization.
How do you test for variant angina?
It is diagnosed by history, electrocardiogram, or coronary-artery angiography. Provocative tests, such as the cold-pressor test or intravenous ergonovine maleate, are sometimes used to aid diagnosis of PVA.
