Key result
Medical treatment is usually advised for variant angina with normal coronary arteries, whereas bypass surgery may be highly effective when it occurs with atherosclerotic disease.
The management of variant angina depends on the underlying coronary anatomy, with medical therapy advised for normal arteries and bypass surgery considered for those with atherosclerotic disease.
Bypass surgery merits consideration in variant angina with atherosclerosis; extends revascularization indications to mixed spasm-stenosis cases.
When a patient's coronary arteries are anatomically normal, variant angina probably results from transient spasm that narrows and occludes a coronary artery; medical treatment is usually advised. But this distinctive type of pain can also occur in conjunction with atherosclerotic disease, in which case bypass surgery may prove highly effective in relieving symptoms and averting the risk of myocardial infarction.

Allen D. Johnson (1978) conducted a review in Variant angina and coronary spasm. Medical treatment or bypass surgery was evaluated. Medical treatment is usually advised for variant angina with normal coronary arteries, whereas bypass surgery may be highly effective when it occurs with atherosclerotic disease.
