P.2. Syncope, Pacemaker, CRT & ICD: P.2.1 Risk Stratification and Follow-Up in Patients Who Attended an Emergency Department Because of Loss of Consciousness

To analyze 1 year follow-up and risk stratification of patients that attended an emergency department because of an episode of loss of consciousness, in a prospective multicenter study performed in 19 hospitals in Spain.

Out of 1428 patients that attended emergency department, 1019 (71%) were discharged (Group [G] I), 397 (28%) (GII) were admitted to the Hospital and 12 died in the emergency department. OESIL score was 1.4±1.1 in GI vs. 2.4±1 in GII. (p <0,001). 128 patients (12,5%) with an OESIL score > 2 were discharged. One year follow-up has been analysed in 814 patients: 607 from GI and 207 from GII. 18 patients from GI (3%) vs. 23 in GII (11%) died (p = 0,05). No one patient from GI vs. 6 in G II received an ICD; 7 patients from GI (1%) vs. 20 in GII (10%) received a pacemaker (p<0,001). The mortality according to OESIL score was: 0% for OESIL 0; 2,5% for OESIL 1; 5% for OESIL 2; 13% for OESIL 3 and 17% for OESIL 4 (p < 0,001).

The admission rate of patients that attended the emergency department because of an episode of loss of consciousness was lower than the reported rate in other series. The risk stratification, the mortality and the implantation rate of an ICD and a pacemaker, was lower in those patients that were initially discharged from emergency department compared with those that were admitted to the hospital. The overall mortality as well as the mortality stratified different risk factors was lower than in other series.
