About 610,000 people die of heart disease in the United States every year–that's 1 in every 4 deaths. Heart disease is the leading cause of death for both men and women.
I'm sure some of these people were bodybuilder, weightlifters etc...
Is the death rate higher among these people can't find any facts but I doubt it.
Dave Palumbo mentioned discussing this with his cardiologist. The doctor claimed to have pulled the numbers and said incidences of dying from heart disease in bodybuilders is roughly the same as the general population.
