Lifetime cumulative incidence of syncope in the general
population: a study
of 549 Dutch subjects aged 35-60 years.

PMID: 17074006

INTRODUCTION: There are limited and conflicting data on the
lifetime
cumulative incidence of syncope in the general population.
The aim of our
study was to determine the lifetime cumulative incidence and
triggers of
syncope in the general population. METHODS: Questions about
syncope were
added to a cross-sectional survey on cardiovascular risk
factors carried out
between 2001 and 2003 in 549 native Dutch respondents, aged
35-60 years.
RESULTS: The lifetime cumulative incidence of syncope in our
study
population was 35% (95% confidence interval 31-39%). Syncope
occurred more
often in women than in men (41% vs 28%; P = 0.003). A peak
in the incidence
of syncope occurred around the age of 15 years in both men
and women. The
median number of episodes in persons with syncope was 2
(Inter Quartile
Range 1-5). The top five most frequently mentioned triggers
of syncope
included warm environment, pain, insufficient food intake,
seeing
blood/venipuncture, and emotion.

CONCLUSION: In conclusion, our study shows that the lifetime
cumulative incidence of syncope in the general population is
high. Females experience syncope more often than males. The
majority of the syncope triggers were related to conditions
that affect orthostatic
blood pressure regulation and vasomotor responses.
