Researchers tracked 12,116 women over a 15 year period when the nurses were aged 45 to 64. By 2008, researchers found that 580 of the nurses had been admitted to hospitals with heart disease, including 138 heart attacks and 369 angina cases.
Researchers say women who describe their work pressures as high are 25 percent more likely to suffer from heart disease than those who said their stress levels at work are manageable.
The study's authors say the findings don't prove that stress at work causes heart disease, only that there appears to be some sort of link between the two.
The study is published in the May issue of the journal Occupational and Environmental Medicine.
