FACTBOX: Risk factors for cardiovascular disease

(Reuters) - Heart disease will cost the U.S. economy $503.2 billion in 2010, the American Heart Association said on Thursday.

Most cases of heart disease, the No.1 killer in the United States and many other countries, could be prevented, the association said. Here are some details on risk factors from the report:

* 59 percent of adults say they never engage in vigorous activity -- exercise that causes heavy sweating and a large increase in breathing or heart rate.

* Fewer than half of even the highest-risk persons are taking statins or other drugs to control their cholesterol.

* Only about one-third of patients who are getting treatment have their low-density lipoprotein (LDL or "bad" cholesterol) at desired levels.

* Fewer than 20 percent of coronary heart disease patients are at their LDL goal.

* Nearly 10 million children and teens (6 to 19 years old) are obese. A third of adults are overweight and another third are obese.
