LDL cholesterol (LDL-C)3, an important modifiable risk factor for atherosclerotic cardiovascular disease, is primarily calculated via the Friedewald equation. However, a newly derived equation for LDL-C estimation was recently published that addressed limitations in the commonly used Friedewald LDL-C calculation method. Mayo Clinic researchers completed a study to evaluate the performance of a novel method to classify patients with superior concordance to measured LDL-C compared to the Friedewald method.
