Relationship between recurrent miscarriage and early preterm delivery and recurrent events in patients with manifest vascular disease: The SMART study

BACKGROUND: Women with a complication of pregnancy are at increased risk of cardiovascular morbidity and mortality later in life. Yet, information on risk of recurrent events in women with a previous cardiovascular event is lacking.

METHODS: We included 1014 women with a mean age of 60 years from the SMART study, a prospective ongoing cohort study among subjects with clinically manifest vascular disease. The included women had a history of ≥1 pregnancy and were followed for the occurrence of subsequent vascular events. The relationship between the pregnancy complications ((miscarriage (gestational age
