Prinzmetal's variant angina associated with subarachnoid hemorrhage: A case report.

Prinzmetal's variant of angina occurred in a 48-year-old man who sustained two attacks of subarachnoid hemorrhage within 10 days. The first anginal pain started at the same time that the second cerebrovascular accident developed, but subsequent anginal episodes were not accompanied by other symptoms or signs that indicated new development of subarachnoid hemorrhage. Twelve days later, when nuchal rigidity was fairly improved, the episodes of chest pain ended. A vasospasm of the large coronary arteries--probably due to the derangement of the autonomic nervous system caused by subarachnoid hemorrhage--was presumed to contribute to the occurrence of the variant angina. Based on this case and on review of the literature, we propose that coronary arterial spasm is one of several causes of the cardiac changes seen in subarachnoid hemorrhage.
