Interestingly, link between stress and cardiovascular ills was found to be strong among men, but weak for women.
It is thought that constant stress may affect the conditions of arteries in a number of direct or indirect ways, from causing chronically high levels of stress hormones to pushing people to maintain unhealthy habits such as smoking.
Throughout a study between 1974 and 1980, middle-age men and women were questioned about their stress levels over the previous 1 to 5 years. They were then followed through 1999 to see who developed cardiovascular disease.
The researchers found that participants who reported chronic stress at the study’s start were 14 percent more likely to develop heart-related problems or suffer a stroke, regardless of other factors like family history, body weight, smoking and high blood pressure.
Though the reason remained unknown, it was men’s risk of fatal stroke that showed the clearest relationship to stress: stress-out men were twice as likely as their peers to die of a stroke. Weaker findings among women were likely due to the fairly low number of heart disease and stroke cases among women.
