Fitness Counts Even for Men with Coronary Risk Factors

Topics: Health Issues

In a study published online today by Circulation, Journal of the American Heart Association, Dr. Katzmarzyk and colleagues of the Queens University in Kingston, Ont. analyzed the cardiovascular risk factors and cardiorespiratory fitness of more than 19,000 men ages 20 to 79. The men were treated at a preventive medicine clinic from 1979 through 1995, prior to the revised treatment guidelines of the National Cholesterol Education Program. The investigators sought to determine whether the new guidelines effectively identified men at risk of cardiovascular mortality.

While the study found that the new categories were effective predictors of cardiovascular death, the researchers were also surprised at the magnitude of risk-reduction associated with physical fitness, which was defined as performance of four to five 30-minutes sessions of exercise per week. The study indicates that even men with high cholesterol levels and other risk factors for heart disease can cut their mortality risk in half by hitting the gym or treadmill four or five times a week, researchers here report.

Regular exercise lowered the mortality risk for men with the highest cholesterol levels from 15 times to only seven times that of men with the lowest cholesterol levels.
