Not a single one of the 326 heart attacks had been predicted by the physicians . The death toll alone is a staggering burden, but it is only part of the picture. One out of every four Americans has CVD, that converts to about 57 million Americans. Heart disease and stroke account for almost 6 million hospitalizations each year and cause disability for almost 10 million Americans age 65 years and older. Also, a number of health-related behaviors practiced by people every day contribute markedly to cardiovascular disease.
Smokers have twice the risk of heart attack as nonsmokers.
One-fifth of the annual 1,000,000 deaths from CVD are attributable to smoking. People who are sedentary have twice the risk of heart disease as those who are physically active. Despite these risks, America remains a predominantly sedentary society. Surveys show that more than half of American adults do not practice the recommended level of physical activity, and more than one-fourth are completely sedentary. If oxygen doesn't arrive the tissue or organ will die.
