RT Journal Article SR Electronic T1 Nocturnal diaphoresis and coronary artery spasm JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 515 OP 518 VO 54 IS 6 A1 Becker, Richard C.

YR 1987 UL http://www.ccjm.org/content/54/6/515.abstract AB Coronary artery spasm may be important in a number of cardiovascular disorders including exertional angina, Prinzmetal’s angina, silent ischemia, myocardial infarction, and sudden cardiac death. Abnormalities of the autonomic nervous system may play an integral role. In a 62-year-old woman with recurrent episodes of nocturnal diaphoresis, intracoronary acetylcholine administration provoked near-total occlusion of the left anterior descending artery. Episodic parasympathetic outflow may be responsible for coronary artery spasm in some patients.
