title: Painless Prinzmetal's ST elevation related to propranolol: a case report.
abstract: Previous studies have shown that propranolol, an effective mainstay for angina pectoris and unstable angina, can induce coronary arterial spasm in patients with variant angina. However, no report has yet associated it with painless Prinzmetal's ST elevation in patients without a history of variant angina. The present communication describes such an unusual and negligible case after propranolol overdose. Coronary arterial spasm can be induced by beta-blocker, not only in patients with variant angina but also in normal persons.
