"Management of Refractory Angina-Drugs, Devices, or Both"

 

Prinzmetal's variant angina

  • This figure illustrates coronary artery vasospasm.

  • In the top frame a localized narrowing of a long segment of the proximal right coronary artery is apparent.

  • The patient had been complaining of intermittent chest pain during at rest.

  • In the bottom frame the abnormality has been corrected by intracoronary nitroglycerin.

  • The response to nitroglycering confirms that the narrowing resulted from coronary vasospasm or Prinzmetal's angina.
