Summary
Angiographic contrast media can cause coronary artery spasm, contrary to common belief. A patient experienced right coronary artery spasm after left ventricular angiography, successfully treated with calcium channel blockers.
Area of Science:
- Cardiology
- Radiology
- Pharmacology
Background:
- Angiographic contrast media are typically viewed as vasodilators.
- However, in vitro studies suggest these agents can induce arterial spasm.
- Clinical evidence linking contrast media to coronary spasm is limited.
