Glucose screening in pregnancy and future risk of cardiovascular disease in women: a retrospective, population-based cohort study

摘要

Background In studies to date, gestational diabetes has consistently been associated with an increased future risk of cardiovascular disease, irrespective of the antepartum screening protocol or diagnostic criteria by which gestational diabetes is diagnosed. We reasoned that the resultant heterogeneity in the severity of dysglycaemia in women with gestational diabetes suggests that the relationship between gestational glycaemia and subsequent cardiovascular disease probably extends into the non-diagnostic range. Thus, we hypothesised that glucose screening in pregnancy would identify future risk of cardiovascular disease in women who did not have gestational diabetes.
