Key result
A 60-year-old man who suffered sudden cardiac arrest due to coronary vasospasm remained free of anginal episodes and ICD therapies at 3 months following ICD placement and verapamil therapy.
Why the study?
Vasospastic angina is an uncommon cause of cardiac arrest.
Case Report (n=1)
Coronary vasospasm can cause life-threatening ventricular arrhythmias and sudden cardiac arrest, which may be diagnosed with ambulatory monitoring and managed with calcium-channel blockers and ICD therapy.

Supports considering vasospasm in unexplained arrest; leaves open ICD role in vasospastic angina.
Vasospastic angina is an uncommon cause of cardiac arrest. We describe a patient who presented with sudden cardiac arrest due to severe coronary vasospasm. Telemetry during the event revealed ventricular arrhythmias and asystole followed by spontaneous self-conversion back to normal sinus rhythm. The patient underwent implantable cardioverter-defibrillator therapy. (Level of Difficulty: Beginner.)

Jiang et al. (2020) conducted a case report in Vasospastic angina and sudden cardiac arrest (n=1). Implantable cardioverter-defibrillator (ICD) and verapamil was evaluated on Recurrence of anginal episodes or ICD therapy. A 60-year-old man who suffered sudden cardiac arrest due to coronary vasospasm remained free of anginal episodes and ICD therapies at 3 months following ICD placement and verapamil therapy.
