Figure 1. Coronary angiographic features of vasospastic angina.

Figure 1.

Selective left coronary angiography of a patient with refractory vasospastic angina in the setting of chronic smoking shows diffuse narrowing of (A) the left circumflex artery, (B) the left anterior descending artery, and their respective branches. Selective right coronary angiography of the same patient shows (C) severe diffuse vasospasm of the right coronary artery, which (D) worsens after intracoronary acetylcholine (ACH) and (E) resolves after intracoronary nitroglycerin (NTG). NTG also vasodilates all major vessels in the left coronary circulation. Adapted from reference [58], with permission from Elsevier.
