Abstract:
A 66-year-old hypertensive woman presented with epigastric and scapular pain on the basis of type 3 aortic dissection. Appropriate therapy with a combined alpha-adrenergic and beta-adrenergic antagonist agent prevented further ongoing dissection and amelioration of symptoms. On day 5, an episode of coronary vasospasm occurred presumably due to beta-blockade with unopposed alpha-adrenergic activity.
