Abstract

Background: Syncope is a temporary loss of consciousness with a loss of postural tone. Medicinal treatment of reflex syncope has shown to have no significant effect in reducing the recurrence of syncope. A 36-month follow-up of our pilot cohort showed that non-pharmacological treatments alone were effective in reducing relapse rates. The purpose of this study is to investigate long-term results and 8-year follow-up of previous patients. Methods: The current study is a continuation of a prospective pilot cohort which was done between August 2013 and 2014 in two academic hospitals in Isfahan (Dr. Chamran heart center and Imam Hossein children hospitals). This current study examines the 8-year follow-up results of children with reflex syncope who were treated with non-pharmacological treatments alone or with drugs. Therefore, the patients who participated in the pilot study were enrolled (30 patients in the pharmacologic group and 40 patients non-pharmacological group). Finally, on 26 patients in the pharmacologic group and 31 patients in the non-pharmacological group (after applying the exclusion criteria), the incidence of syncope and pre-syncope attacks was compared between these two groups of patients using the Chi-square test. Results: Our study showed that within 5 years after the last follow-up, the incidence of syncope and pre-syncope in patients with a history of vasovagal syncope who did not continue the diet or tilt exercises was different between the two groups of patients (without medication and drug recipient) was not significantly different, even the incidence of presyncope increased significantly again in both groups. The incidence of syncope in the period of 5 years after the last follow-up from the previous study was slightly increased in the group of patients without medication compared to the previous periods, but in the group of patients receiving medication, this incidence decreased slightly. Conclusion: In order to prevent recurrence, the use of non-pharmacological methods is effective, but for the stability of this recovery, follow-up and continuation of these methods is necessary.
