Christopher Ruhm, an economics professor at the University of North Carolina at Greensboro wrote in his study that there is a pronounced increase in death rate due to heart attacks, when the economy grows further with no improvement in the rate of unemployment. Statistics have shown that even a one percentage decline in unemployment can cause the mortality rate to rise by 1.3 percent or 2,515 additional deaths per year from heart attacks, with the rates of mortality being alike for both male and female.
An economic upswing witnesses the 20-44 age groups portraying a high risk of heart attack, compared to the older people. Ruhm, said "During that period of time chances are you are working so much you are not exercising, haven't had a chance to join a gym, you're eating out a lot, maybe smoking more. When the economy heats up, people often end up working more overtime."
