Answer

The recommendations on management of blood cholesterol were released in November 2018 by the ACC, AHA, and multiple other medical societies. [23, 24]

The guideline's top 10 key recommendations for reducing the risk of atherosclerotic cardiovascular disease through cholesterol management are summarized below.

Emphasize a heart-healthy lifestyle across the life course of all individuals.

In patients with clinical atherosclerotic cardiovascular disease (ASCVD), reduce low-density lipoprotein cholesterol (LDL-C) levels with high-intensity statin therapy or the maximally tolerated statin therapy.

In individuals with very high-risk ASCVD, use an LDL-C threshold of 70 mg/dL (1.8 mmol/L) to consider the addition of nonstatins to statin therapy.

In patients with severe primary hypercholesterolemia (LDL-C level ≥190 mg/dL [≥4.9 mmol/L]), without calculating the 10-year ASCVD risk, begin high-intensity statin therapy.

In patients 40 to 75 years of age with diabetes mellitus and an LDL-C level of ≥70 mg/dL: Start moderate-intensity statin therapy without calculating their 10-year ASCVD risk.

In patients aged 40 to 75 years evaluated for primary ASCVD prevention: Have a clinician–patient risk discussion before starting statin therapy.

In nondiabetic patients aged 40 to 75 years and with the following characteristics:

  • LDL-C levels ≥70 mg/dL (≥1.8 mmol/L), at a 10-year ASCVD risk of ≥7.5%: Start a moderate-intensity statin if a discussion of treatment options favors statin therapy.

  • A 10-year risk of 7.5-19.9% (intermediate risk): Risk-enhancing factors favor initiation of statin therapy.

  • LDL-C levels ≥70-189 mg/dL (≥1.8-4.9 mmol/L), at a 10-year ASCVD risk of ≥7.5-19.9%: If a decision about statin therapy is uncertain, consider measuring coronary artery calcium (CAC) levels.

Assess patient adherence and the percentage response to LDL-C–lowering medications and lifestyle changes with a repeat lipid measurement 4-12 weeks after initiation of statin therapy or dose adjustment; repeat every 3-12 months as needed.
