A pregnancy loss invariably raises a woman's concerns about her reproductive health. However, other pregnancy problems, such as high blood pressure or diabetes, may also provide an early warning of future heart disease. "Pregnancy affects your heart and cardiovascular system, and gestational problems can be an indicator of how well your system deals with stress," says Dr. Malissa Wood, co-director of the Corrigan Women's Heart Health Program at Harvard-affiliated Massachusetts General Hospital.
