Abstract
Abstract only Introduction: Guidelines are increasingly recommending a goal LDL-C <55 mg/dL in persons with atherosclerotic cardiovascular disease (ASCVD). The proportion and characteristics of US adults with ASCVD with an LDL-C <55 mg/dL remains unclear. Aims: To evaluate lipid management in ASCVD patients and factors associated with achieving an LDL-C <55mg/dL. Methods: Using electronic health record data from 8 US health systems, we evaluated LDL-C levels and treatment patterns in persons with prevalent ASCVD seen as outpatients between 1/1/2021-12/31/2021 with an LDL-C level within the prior year. Multivariable logistic regression modeling with generalized estimating equations was used to evaluate factors associated with an LDL-C <55 mg/dL. Results: Among 178,240 eligible ASCVD patients, 43.5% (77,472) had an LDL- C <70 mg/dL and 22.0% (39,270) had an LDL-C <55 mg/dL. Older age was associated with higher odds of LDL-C <55 mg/dL (OR 1.10 per 10 years, 95% CI 1.07-1.13), while female sex (OR 0.71, 95% CI 0.68-0.64) Black race (OR 0.77, 95% CI 0.70-0.86), and non-coronary artery disease forms of ASCVD including peripheral artery disease (PAD, OR 0.61, 95% CI 0.58-0.64) and cerebrovascular disease (CeVD, OR 0.72, 95% CI 0.66-0.79) were associated with lower odds of LDL-C <55 mg/dL in multivariable modeling. Overall, while 75.0% were on a statin, only 36.9% were on a high-intensity statin, 5.7% were on ezetimibe, and 1.7% were on a PCSK9i. Combination therapy was rare: only 4.2% were on a statin+ezetimibe, 0.5% on statin+PCSK9i, and 0.3% on all three. Conclusions: Less than a quarter of US patients with ASCVD achieve an LDL <55 mg/dL. Achieving this goal is even less common among younger adults, women, Black persons, and those with PAD and CeVD. Current therapeutic regimens often fail to use high-intensity statins, and markedly underutilize combinations of statins with ezetimibe and/or PCSK9 inhibitors.
