MedicalResearch.com: What are the main findings of the study?Dr. Sheiner:The study was aimed to investigate whether a history of preterm delivery (PTD) poses a risk for subsequent maternal long-term cardiovascular morbidity.
During the study period 47,908 women met the inclusion criteria; 12.5% (n=5992) patients delivered preterm. During a follow-up period of more than ten years, patients with PTD had higher rates of simple as well as complex cardiovascular events and higher rate of total cardiovascular related hospitalizations. A linear association was found between the number of previous PTD and future risk for cardiovascular hospitalizations (5.5% for two or more PTD, 5.0% for one PTD vs. 3.5% in the comparison group; P<0.001). The association remained significant for spontaneous vs. induced PTD and for early (<34 weeks) as well as late (34-36+6 weeks) PTD. In a Cox proportional hazards model that adjusted for pregnancy confounders such as labor induction, diabetes mellitus, preeclampsia and obesity, PTD was independently associated with cardiovascular hospitalizations (adjusted HR 1.4, 95% CI 1.2-1.6).
