Victims of stalkers appear to have an increased risk of heart disease, a new study says.

Women who had been stalked or had obtained a restraining order were more likely to develop heart problems later in life, researchers reported in the journal Circulation.

"Stalking is often seen as a form of violence that does not involve physical contact, which may make it seem less serious," said lead researcher Rebecca Lawn, a research associate in epidemiology at Harvard T.H. Chan School of Public Health in Boston.

"However, our findings suggest stalking should not be minimized," she added in a news release.
