Provocative testing for coronary reactivity and spasm.
Coronary spasm is an important and often overlooked etiology of chest pain. Although coronary spasm, or Prinzmetal's angina, has been thought of as benign, contemporary studies have shown serious associated adverse outcomes, including acute coronary syndrome, arrhythmia, and death. Definitive diagnosis of coronary spasm can at times be difficult, given the transience of symptoms. Numerous agent...
متن کاملA renaissance of provocative testing for coronary spasm?
The term variant angina, first used by Prinzmetal et al. (1) in 1959, denotes chest discomfort with classic features of angina but occurring at rest or at night (usually the early morning hours) rather than with exertional or emotional stress. The pain is often associated with ST segment elevation and is relieved by nitroglycerin. A female predominance and frequent association with cigarette sm...
متن کاملMultivessel coronary artery spasm.
A 60-year-old patient with variant angina was shown to have myocardial ischemia in two different regions supplied by separate major coronary arteries. Neither artery had significant coronary atherosclerotic obstruction. Ventricular fibrillation was noted during ST-segment elevation in anteroseptal leads. The attacks of pain and arrhythmias disappeared during nifedipine therapy.
متن کاملCoronary Artery Spasm
Case presentation: A 37-year-old man was admitted in the early morning hours to the emergency department after experiencing excruciating chest pain. The patient was a heavy smoker who gave a history of several previous similar but less intense episodes of pain during the past 2 years; most of them also during the early morning hours. One of his earlier attacks was associated with sensing his he...
متن کاملCoronary artery spasm.
Coronary artery spasm is a transient reduction in lumen diameter of an epicardial coronary artery of sufficient degree to produce objective evidence of myocardial ischemia in the absence of any significant increase in heart rate or blood pressure. In this article are summarized pathophysiological observations, the coronary angiographic anatomy of patients with coronary spasm, etiologic consider...
