A Short History of Vasospastic Angina
The syndrome of chest pain and/or myocardial ischemia with normal or nonobstructive coronary arteries at angiography is common and is of practical importance to the general medical audience. Many studies have tried to address this topic over the last 4 decades. Only 1 thing is clear: for patients with ongoing signs and symptoms of ischemia in acute coronary syndromes, the prognosis is not so favorable, as believed earlier in the 1990s. Yet, physicians remain confused by other patients who refer a history of effort angina or angina-like chest pain whose coronary angiograms show no evidence of obstructive coronary artery disease (CAD) and who have no structural heart disease.
