Preterm Delivery: A Potential Heart Disease Risk Factor in Women

Women are at higher risk of developing cardiovascular disease, including coronary heart disease and stroke, later in life, who have a history of preterm delivery (PTD), reports a new study. The findings of the study are published in the Journal of Women's Health. The study, which used a novel Markov microsimulation model to quantify CVD burden in terms of cost and years of life lost over a 50-year period, is published in a peer-reviewed publication from Mary Ann Liebert, Inc., publishers.

The article entitled "How Does Preterm Delivery Contribute to the Increased Burden of Cardiovascular Disease? Quantifying the Economic Impact of CVD in Women with a History of Preterm Delivery" was coauthored by Lan Gao, Ph.D., Shu-chuen Li, Ph.D., and Marj Moodie, DrPh, Deakin University (Geelong) and The University of Newcastle (Callaghan), Australia. While PTD is not traditionally recognized as a CVD risk factor, it places the mother at increased risk of developing CVD, including coronary heart disease and stroke, later in life, and women who have a PTD have about twice the risk of CVD mortality.

Based on an Australian healthcare system perspective, the study comprised two models, a dynamic model and a static model which showed the total CVD cost burden to be 11.4 billion Australian dollars and 4.5 billion Australian dollars, respectively, over the 50-year study period. The years of life lost were 0.34 per capita and 0.52 per capita, respectively.

In an accompanying editorial entitled "The Economic Burden of CVD in Women with a History of Preterm Delivery," Margo Minissian, Ph.D., Cedars-Sinai Medical Center (Los Angeles, CA) states: "Considering the substantial economic burden eloquently described by Gao et al., future prevention strategies for women who experience PTD are imperative." In addition, "recognizing PTD as a potential CVD risk factor/enhancer is important."

Dr. Minissian highlights the novel microsimulation modeling technique used in this study, which allows for subsequent recurrent CVD events to be captured over a lifetime. Most notable was the 19.8% 4-year recurrence rate of stroke.
