“…1-3 Neurologic examination using the Glasgow Coma Scale (GCS) 5 is a universal, simple, and costless procedure, but such a neurologic examination on admission has not been fully evaluated in comatose survivors of CA. 1,2,6- 13 The aim of the present study was to determine the association between GCS, in particular initial motor score (on admission), and neurologic outcome, in patients with out-of-hospital CA who receive TH.…”

“…The prevalence of CAS in patients resuscitated from cardiopulmonary arrest is 7.4% in Japan3 and 8.6% in Western countries 6. In addition, inferolateral J wave has been reported in 21% to 36% of patients with CAS 9, 10.…”

“…In a multicenter study conducted by Haïssaguerre et al, provocation using ergonovine was performed in only 19 of 122 patients with ERS (16%) 12. However, Kobayashi et al reported that only 3 of 12 patients with CAS with cardiac arrest experienced prodromal chest symptoms 3. This indicates that a considerable number of patients with CAS without chest symptoms may have been included in cases with idiopathic VF and inferolateral J wave.…”

BackgroundPreviously described patients with early repolarization syndrome (ERS) may have experienced silent coronary artery spasm (CAS) because the diagnosis of CAS was mainly based on symptoms or coronary angiography findings, without performing a spasm provocation test. This study investigated the significance of CAS diagnosis and evaluated the incidence of silent CAS in patients with possible ERS (ie, idiopathic ventricular fibrillation [VF] and inferolateral J wave).Methods and ResultsThe study included 34 patients with idiopathic VF and inferolateral J wave. Thirteen patients (38%) were diagnosed as having CAS on the basis of coronary angiography with spasm provocation test (n=8) and documentation of spontaneous ST elevation (n=5). Of the 13 patients with CAS, 5 (38%) did not experience chest symptoms before and during VF, and were diagnosed as having silent CAS. The remaining 21 patients (62%), with a negative provocation test result and absence of chest symptoms, were considered to have ERS. During the 92 months of follow‐up, patients with CAS receiving appropriate medical treatment with antianginal drugs showed a favorable outcome. In contrast, 4 of 21 patients with ERS (19%) had VF recurrences. The use of monotherapy or combination therapy, consisting of quinidine, cilostazol, and bepridil, in the 4 patients with ERS, was effective in suppressing VF.ConclusionsApproximately 40% of patients with CAS with documented VF and inferolateral J wave did not experience chest symptoms at the first VF, and could have been misdiagnosed as having ERS. The use of the spasm provocation test is considered essential to differentiate patients for optimal medical treatment.
