Variant (Prinzmetal's angina)

Explanation:

Prinzmetal's Angina, also called Variable Angina is a syndrome characterized by episodes of ischemic pain that occur at rest (during sleep and more often in the early hours of the morning, as with Harvey). This syndrome is caused by a coronary vasospasm (temporary narrowing of a vessel). Treatment is with ingestion of nitrates and calcium channel blockers.
