Despite the high prevalence of cholesterol screening and awareness, only ≈50% of US adults with familial hypercholesterolemia (FH) are on statin therapy, with even fewer prescribed a high-intensity statin. Researchers used data from the 1999 to 2014 National Health and Nutrition Examination Survey to estimate prevalence rates of self-reported screening, awareness, and statin therapy among US adults (n=42,471 weighted to represent 212 million US adults) with FH and with severe dyslipidemia (defined as low-density lipoprotein cholesterol [LDL-C] levels ≥190 mg/dL). They found:
- The frequency of cholesterol screening and awareness was high (>80%) among adults with definite/probable FH or severe dyslipidemia.
- However, statin use was uniformly low (52.3%) in adults with definite/probable FH and 37.6% in adults with severe dyslipidemia.
- Only 30.3% of patients with definite/probable FH on statins were taking a high-intensity statin.
- Young and uninsured patients are at the highest risk for lack of screening and for undertreatment.
