Vascular Path (section 2) Flashcards
What is Myocardial Vessel Vasospasm?
Excessive vasoconstriction of myocardial arteries that may result in ischemia/infarct
What are 2 possible causes of Myocardial Vessel Vasospasms?
- Excessive vasoactive mediators
ex. cocaine, caffeine, epi and norepi. - Excessive thyroid hormones
