Painless coronary spasm in the absence of fixed coronary disease was the underlying etiology in two cases of resuscitated sudden cardiac death.
Painless coronary spasm can be a cause of sudden cardiac death in patients with near normal coronary arteries.
May support spasm evaluation in resuscitated SCD with near-normal arteries; hypothesis-generating case reports leave prevalence and management open.
Two cases of resuscitated sudden cardiac death are described; one was due to ventricular fibrillation and the other to ventricular asystole. In both cases the underlying etiology was painless coronary spasm and no fixed coronary disease.
