Cholesterol screening should be targeted.

For primary prevention of coronary heart disease (CHD), the American College of Physicians (ACP) has recommended that initial cholesterol screening be targeted to people who have other risk factors in addition to elevated cholesterol. This would include those with symptoms of heart disease, asymptomatic men 35-65 years old and women 45-65 years old, or younger people who have > or = 2 risk factors or who might benefit from treatment for high blood cholesterol. After the age of 75, cholesterol is no longer a risk factor, so there is no rationale for testing. In primary prevention, lipoprotein fractionation should be performed in men and women who have been identified as having elevated blood cholesterol levels, not as part of initial testing. In secondary prevention, some studies indicate that cholesterol reduction may be beneficial after age 65. In asymptomatic younger people without other risk factors, the low prevalence of CHD and rapid response to cholesterol reduction once it is initiated suggest that early screening and treatment are unnecessary. Everyone should adopt the lifestyle modifications conducive to cardiovascular health, but the ACP believes that, for primary prevention, universal screening is neither cost effective nor the best use of the patient's and physician's time.
