Heart disease a newfound legacy of 9/11 disaster

A review of 1980 individuals who sustained physical injuries such as fractures or burns in the attack, recorded in the World Trade Center Health Registry, showed a threefold higher risk of heart disease among those with multiple injuries and post-traumatic stress disorder (PTSD).

In addition, those with multiple injuries but without PTSD had double the risk of respiratory disease in the six years following the disaster.

There was a dose-response relationship between the number of types of injury and chronic disease, the authors said.
