Syncope during pregnancy increases risk for poor outcomes

Key clinical point: Syncope during pregnancy, especially in the first trimester, is a risk factor for adverse outcomes.

Major finding: Pregnancies with first-trimester syncope had a higher rate of preterm birth (18% vs. 15%, P less than .01), and pregnancies with multiple episodes of syncope at any time had a higher rate of congenital anomalies (5% vs. 3%, P less than .01).

Study details: Retrospective population-based cohort study of 481,930 pregnancies occurring during 2005-2014 in Alberta.

Disclosures: The investigators disclosed no relevant conflicts of interest. This study was funded by a grant from the Cardiac Arrhythmia Network of Canada.
