PABON, Guillermo Mora et al. Frequency of adverse events in the short and medium term in patients with syncope classified as high and low risk according to the OESIL score. Rev. Colomb. Cardiol. [online]. 2017, vol.24, n.3, pp.241-249.  Epub Dec 18, 2016. ISSN 0120-5633.


To assess the frequency of adverse events in patients over 18 years old with syncope and their relationship with criteria of the OESIL risk score in those who attended the emergency room of five hospitals in Cundinamarca.


A cohort study was conducted which included patients over the age of 18 years who attended the emergency room with a syncope diagnosis between January 2014 and December 2015.

OESIL score information was collected. During the follow up at 7, 30 and 90 days, death, recurrence, rehospitalization, cardiological interventions and neurological events were determined.


173 patients were included with an average age of 69 years, of whom most had syncope in the absence of prodromes (70.5%). Scores higher than 2 were classified as high risk (71.6%). Statistically significant differences were evidenced in the outcome of cardiological interventions during the follow up, as well as a higher incidence of any adverse event at 30 and 90 days within the high risk group.

Survival analysis indicated that the group with scores higher than 1 in the OESIL scale are twice more likely at risk of presenting any event with a hazard ratio of 2.11.


According to the OESIL score, there is a higher number of deaths and cardiological interventions in patients with high risk syncope.
