The risk of thrombosis in women giving birth for the first time was 10- to 11-fold higher in the first 6 weeks postpartum, but in a report presented at the International Stroke Conference, Dr. Hooman Kamel of Cornell University, N.Y., and his colleagues found that the risk of thrombosis (stroke, MI, and venous thromboembolism) is still doubled during 7-12 weeks postpartum. The study was published Feb. 13 in the New England Journal of Medicine in conjunction with the report at the conference (2014 Feb. 13 [doi:10.1056/NEJMoa1311485]).
