How much does lifestyle modification actually matter?

The absolute impact of diet and exercise on lipid parameters is relatively modest. No studies have demonstrated a reduction in adverse cardiovascular outcomes with specific interventions regarding diet or activity.

Diet. Nevertheless, ACC/AHA recommends that at-risk patients follow a dietary pattern that (1) emphasizes vegetables, fruits, and whole grains and (2) limits sweets, sugar-sweetened beverages, and red meat.

For adults ≥ 20 years of age who are not receiving lipid-lowering therapy, a nonfasting lipid profile can be used to estimate ASCVD risk and document the baseline LDL-C level.

Saturated fat should constitute no more than 5% or 6% of total calories. In controlled-feeding trials,¹⁰ for every 1% of calories from saturated fat that are replaced with carbohydrate or monounsaturated or polyunsaturated fat, the LDL-C level was found to decline by as much as 1.8 mg/dL. Evidence is insufficient to assert that lowering dietary cholesterol reduces LDL-C.¹¹

Activity. Trials of aerobic physical activity, compared with a more sedentary activity pattern, have demonstrated a reduction in the LDL-C level of as much as 6 mg/dL. All adult patients should be counseled to engage in aerobic physical activity of moderate or vigorous intensity—averaging ≥ 40 minutes per session, 3 or 4 sessions per week.¹¹

Primary prevention:Stratification by age

40 to 75 years. ACC/AHA recommends that you routinely assess traditional cardiovascular risk factors for these patients and calculate their 10-year risk for ASCVD using the PCE. Statin therapy as primary prevention is indicated for 3 major groups (TABLE 1).⁴ The US Preventive Services Task Force (USPSTF) recommends a 10-year ASCVD risk ≥ 10%, in conjunction with 1 or more additional CVD risk factors (dyslipidemia, diabetes, hypertension, smoking), as the threshold for initiating low- or moderate-intensity statin therapy in this age group.¹²
