As per a recent study, it has been revealed that heart attack survivors, who live within 100 metres of major roadways, are at a greater risk of dying than those who live at least 1,000 metres away.

A survey was being conducted, which involved 3,547 heart attack survivors, who were around 62 years. The survey revealed that the heart attack survivors are at 27% increased risk of death and that too within 10 years, but only if they live within the radius of 100 metres of major roadways.

In addition, it has been found that people, who live 100 to 199 metres from major roadways, have 19% increased risk of death. However, those who live 200 to 999 metres away are at 13% increased risk of death.

Study author Murray A. Mittleman, who is Director of the Cardiovascular Research Unit at Beth Israel Deaconess Medical Centre in Boston, said, "We think there is exposure to a combination of air pollution near these roadways and other exposure, such as excessive noise or stress from living close to the roadway".

The study continued for 10 years and assessed the deaths of 1,071 deaths. It was found that 672 people have lost their lives due to cardiovascular causes.
