What is it about?
Vasospastic angina (VSA) is a benign disorder, but sometimes leads to acute coronary syndrome and life-threatening ventricular arrhythmias. Patients resuscitated from sudden cardiac arrest (SCA) due to VSA are at a high risk of recurrent lethal arrhythmia. However, the effects of Implantable cardioverter-defibrillator (ICD) implantation on these patients remain inconclusive. We showed there was no significant difference in the incidence of the primary endpoint (a composite of all-cause death and appropriate ICD therapy) between patients with (n=51) and without (n=229) VSA during a median follow-up period of 3.8 years (24% vs. 33%, p = 0.19).

Why is it important?
Long-term clinical outcomes were not different between patients with and without VSA. ICD therapy may be considered in patients with VSA and those with other etiologies after resuscitation from SCA.
