What is the long-term prognosis of patients with coronary spasm and normal coronary arteries?
The clinical course of patients with pure coronary artery spasm is variable. Some patients have a chronic course characterized by recurrent angina at rest. Others develop spontaneous remission of symptoms. Most patients have a poor response to long-acting nitrate therapy and a good response to calcium antagonists. Despite the morbidity associated with this syndrome, cardiac mortality is low. When death occurs, it is usually sudden and probably secondary to an arrhythmia.
