Unemployment could increase risk of heart attack

Researchers say stress goes up any time people don't feel in control of their lives.

Itâ??s no surprise that unemployment can put a huge strain on your health, but a new study suggests it could also put you at higher risk of having a heart attack.

Scientists at Duke University found people who are unemployed at some time in their lives are at an increased risk of heart attack after the age of 50.

People who experienced four or more job losses in their lifetime had a 63 percent higher risk of heart attack compared to those who had never experienced unemployment, the study found.

The risks were also the same for men and women, for all races and ethnic groups and for rich and poor people. The study finds that a job loss can pose the same dangers as smoking, high blood pressure or diabetes.

The study is published in the Archives of Internal Medicine.
